The article from CleanTechnica critically examines the common defense of hydrogen fuel cell forklifts as evidence that hydrogen technology is succeeding in transport applications. It argues that citing hydrogen forklifts to rebut broader critiques of hydrogen transport is misleading because it ignores the scale of the market. While a few thousand hydrogen forklifts may sound significant, they represent less than 0.1% of the global forklift market, which sells around 2.2 to 3 million units annually. The vast majority of forklifts are battery electric, with hydrogen forklifts constituting a negligible "rounding error" rather than a meaningful market share. Focusing on the U.S. market, the article notes that although hydrogen forklifts are somewhat more visible, they still account for only a small fraction of total forklift sales—about 50,000 to 60,000 units over more than a decade—compared to hundreds of thousands of battery electric forklifts sold annually. Even prominent users like Amazon, Walmart, and Home Depot

The article from CleanTechnica addresses the recurring question of why hydrogen buses continue to be purchased despite their operational struggles compared to battery electric buses, which have proven successful in many cities. It argues that these decisions are often mistakenly attributed to corruption or bribery. Instead, the root causes lie in systemic issues such as institutional structures, delegated authority, misaligned incentives, legal lobbying, cognitive biases, and entrenched industrial policies. Most transit agency personnel act with good intentions but face organizational and strategic limitations that hinder optimal technology evaluation. Public transit agencies are primarily designed for operational efficiency—running buses on time, ensuring safety, managing labor, and budgeting—rather than conducting strategic assessments of emerging propulsion technologies. Since the last major transition in transit propulsion occurred decades ago, agencies lack the institutional expertise to thoroughly compare the costs, infrastructure needs, and risks of new technologies like hydrogen versus battery electric buses. Consequently, agencies often defer to national or regional authorities for guidance. In many cases, these higher-level bodies promoted hydrogen due

The article "When Hydrogen Transport Failures Stop Being Surprising" from CleanTechnica examines a recurring pattern in hydrogen transport projects worldwide, highlighting the recent decision by Liverpool City Region to convert its hydrogen buses to battery electric vehicles due to fuel supply constraints. This pattern, described as the "odyssey of the hydrogen fleet," typically begins with strong political enthusiasm and public funding aimed at zero-emission transport pilots. Initial deployments face delays, complex infrastructure challenges, high and volatile fuel costs, and maintenance difficulties. Despite early optimism, these projects often struggle with operational reliability and low utilization, leading to limited fleet expansion and a shift in public messaging toward future improvements rather than current performance. Over time, as battery electric vehicle technology improves and becomes more cost-effective, operators reassess hydrogen projects. The decision to mothball, sell, or convert hydrogen assets becomes common, framed as a learning experience rather than a failure. Liverpool’s choice to switch to battery electric buses aligns with similar decisions made in California, Germany, and

A new pilot project announced by New Jersey Governor Phil Murphy will introduce six hydrogen fuel cell electric trucks to Port Newark, one of the busiest East Coast seaports and a critical hub in the Port Authority of New York and New Jersey. These trucks will be used for drayage—short-distance transport of shipping containers from the port to nearby warehouses and rail yards—addressing the significant local air pollution caused by traditional diesel drayage trucks, which account for about 48% of the port’s greenhouse gas emissions. The project aims to reduce emissions in this high-impact area while acknowledging current limitations in hydrogen refueling infrastructure and battery electric truck recharge times for long-haul routes. The initiative is funded by the New Jersey Economic Development Authority and managed by Rutgers University’s Center for Advanced Infrastructure and Transportation, with partners including utility PSEG, Hyundai Motor Company, and the Port Authority. Beyond emissions reductions, the project seeks to establish New Jersey as a research, development, and workforce training hub for hydrogen-powered

The article compares battery-electric vehicles (EVs) and hydrogen fuel-cell vehicles (FCEVs) as two different electric drivetrain technologies aimed at reducing emissions from transport. EVs store electricity directly in batteries and convert it efficiently into motion, achieving about 70-90% energy efficiency due to fewer conversion steps. Their charging infrastructure leverages the existing electricity grid, which is widespread and increasingly powered by renewables. In contrast, hydrogen cars store energy as compressed hydrogen gas, which is converted back into electricity via fuel cells. However, the entire hydrogen production and usage chain—electrolysis, compression, transport, and conversion—results in significantly lower overall efficiency (25-45%) and greater energy losses. From a climate perspective, lifecycle analyses show battery EVs currently produce 70-75% fewer greenhouse gas emissions than petrol cars, benefiting from direct grid connection and improving grid decarbonization. Hydrogen cars can approach similar low emissions only if the hydrogen is “green,” produced from renewable electricity;

Hyundai, a leading Korean automaker known for its successful electric vehicle (EV) lineup, continues to invest in hydrogen fuel cell EVs despite challenges, particularly in the U.S. market where federal policies have been unfavorable to EV adoption. Hyundai is collaborating with French gas company Air Liquide under a renewed Memorandum of Understanding to develop a sustainable hydrogen energy ecosystem spanning Europe, the U.S., and South Korea. Their partnership focuses not only on fuel cell vehicles but also on hydrogen production, storage, transportation, and broader clean energy solutions to support the global energy transition. This collaboration is part of the broader Hydrogen Council, an industry group founded in 2017 by major companies including Hyundai, Air Liquide, BMW, and Toyota, aimed at advancing hydrogen technologies in line with the Paris Agreement on climate change. While green hydrogen development has faced setbacks and slow progress globally, especially in Europe, the Council and its members remain committed to scaling hydrogen use, particularly in heavy-duty transport, logistics, and public

The article from CleanTechnica analyzes Solaris' position in Europe’s zero-emission bus market, highlighting that while Solaris is currently the largest supplier of hydrogen buses on the continent, it is doing so in a segment that is losing momentum. In 2024, Europe registered only a few hundred hydrogen buses compared to nearly 8,000 battery electric buses, reflecting a strong market shift toward battery electric technology. National and municipal transport agencies across Europe are increasingly scaling up battery electric fleets, closing hydrogen refueling stations, and removing hydrogen from procurement plans. Solaris’ leadership in hydrogen buses places it at the top of a shrinking market, which risks contraction as operators favor technologies with better economics and clearer strategic futures. Solaris built its zero-emission reputation during a period when hydrogen enjoyed political support and EU funding, offering a broad portfolio including battery electric, hydrogen fuel cell, trolleybuses, and hybrids alongside legacy diesel and CNG lines. However, this breadth has introduced complexity and diluted focus, especially as the

A review of eight Polish municipal projects funded by the EU’s Green Public Transport program reveals a widespread neglect of the Energy Efficiency First (EE1st) principle, which mandates comparing energy use and costs before selecting zero-emission bus technologies. Despite EU law, seven out of eight cities failed to conduct any meaningful energy or cost-efficiency comparisons between hydrogen fuel-cell buses (FCEVs) and battery-electric buses (BEVs). The subsidy structure favored hydrogen buses by offering up to 90% funding compared to 80% for BEVs, incentivizing cities to choose the more expensive and energy-intensive hydrogen option. This has led to public funds being spent on buses that consume 4–5 times more electricity and cost 4–6 times more to operate than BEVs. Operational data from Polish cities confirm the inefficiency of hydrogen buses. For example, BEVs in Białystok consume 85–130 kWh per 100 km, while hydrogen buses require about 490 kWh per

Hyundai Motor Company made a significant return to the Japan Mobility Show (JMS) in 2025 after a 12-year hiatus, unveiling its largest public presence in Japan. Rather than directly competing with dominant Japanese automakers in the hybrid passenger vehicle market, Hyundai focused on two niche areas where it holds technological advantages: hydrogen fuel cell vehicles and integration with digital gaming culture. The highlight was the Japan debut of the all-new NEXO fuel cell electric vehicle, representing nearly three decades of Hyundai’s hydrogen research. The second-generation NEXO offers an impressive WLTP range of over 826 kilometers from a five-minute hydrogen refuel, thanks to increased tank capacity and improved powertrain performance, including better low-temperature operability and winter drivability. Hyundai aims to position itself as a collaborative partner in Japan’s hydrogen society vision rather than a competitor, with plans to launch the NEXO in Japan in the first half of 2026. In addition to the NEXO, Hyundai showcased its

The article from CleanTechnica examines the troubled trajectory of Horizon Fuel Cell Technologies and its subsidiary Hyzon Motors, highlighting the disconnect between Horizon’s ambitious hydrogen energy goals and the reality of its business performance. While Hyzon, which went public via a SPAC and aggressively promoted hydrogen fuel cell trucks, collapsed amid regulatory, financial, and operational challenges, Horizon itself has largely flown under the radar despite supplying Hyzon’s technology and leadership. The CEO, Craig Knight, who led both companies, continues to advocate for hydrogen as a key energy carrier despite the clear setbacks and failures, raising questions about Horizon’s governance and strategic direction. Horizon presents itself as a global engineering firm focused on hydrogen systems, but its only consistent commercial success lies in educational products—small-scale fuel cell kits for classrooms and hobbyists. Attempts to scale hydrogen technology into commercial markets such as heavy-duty trucks, Chinese hydrogen buses, UAV fuel cells, and stationary power systems have failed to deliver viable business outcomes. Hyzon’s failure was particularly

The EU Innovation Fund has awarded a €21.4 million grant to ZeroAvia, a US-UK company, to retrofit 15 Cessna Caravan aircraft with ZA600 hydrogen fuel cell electric engines. This pilot project, part of the ODIN initiative, aims to introduce zero-emission hydrogen fuel cell aircraft into commercial operations within the European Economic Area, specifically across 15 Norwegian airports equipped with hydrogen refueling and storage facilities. The retrofitted aircraft are expected to replace conventional kerosene-fueled turboprops on cargo routes, achieving over a 95% reduction in greenhouse gas emissions. This marks a significant step toward decarbonizing regional air travel and establishing the world’s largest network of zero-emission commercial flights. The project addresses the “chicken-and-egg” challenge of hydrogen fuel infrastructure, similar to early electric vehicle adoption hurdles, by developing a green hydrogen supply chain supported by the European Commission.

The agrivoltaic industry, which integrates solar power generation with agricultural activities, has rapidly evolved since its inception a few years ago. Recently, researchers have begun exploring the combination of agrivoltaics with green hydrogen production, aiming to create dual-use systems that simultaneously support food production and clean energy generation. A University of Exeter research team conducted a financial analysis of a simulated 1-gigawatt agrivoltaic solar farm coupled with an on-site electrolysis facility for green hydrogen production. Their study focused on growing tomatoes under solar panels while producing hydrogen fuel for fuel cell electric vehicles (FCEVs) in regions including Australia, California, China, Nigeria, and Spain. Despite some reduction in crop yields due to shading, the land equivalent ratio (LER) calculations showed positive economic benefits across all locations, with Nigeria and Spain leading. The study highlights that although green hydrogen remains costly and its adoption has been slow, government policies and industrial demand continue to drive interest in the technology.

General Motors (GM) has officially ended its development of the next-generation Hydrotec hydrogen fuel cells for transportation, concluding a decades-long experiment with hydrogen propulsion. Despite early efforts dating back to the 1966 Electrovan and multiple revivals tied to policy shifts and oil prices, GM acknowledged that hydrogen fuel cells are not a viable solution for road vehicles due to persistent technical, economic, and infrastructure challenges. The company highlighted the inefficiency of hydrogen energy conversion—where less than a third of the original electricity is retained after electrolysis, compression, transport, and reconversion—compared to battery electric systems that deliver about 75% of grid energy to wheels. GM’s Hydrotec initiative, which included partnerships with Honda, Wabtec, and Nikola Motors, ultimately faltered as these collaborations dissolved or failed, with Nikola’s bankruptcy notably ending a key hydrogen trucking project. The company cited high costs, sparse hydrogen refueling infrastructure (around 60 stations in the U.S.), and weak consumer

The article discusses the practical challenges and economic realities that undermine the widespread adoption of hydrogen fuel cell technology in public transportation, using the example of Bayreuth, a Bavarian city. Initially, Bayreuth planned to decarbonize its bus fleet with hydrogen fuel cell vehicles supported by renewable energy and significant government funding. However, after conducting a neutral techno-economic assessment, the city reversed its decision and opted for battery-electric buses instead. This shift highlights a broader trend: when full system costs—including electricity inputs, conversion losses, infrastructure, maintenance, and operation—are objectively analyzed, hydrogen consistently proves less cost-effective than direct electrification. The article further explains the inherent inefficiencies of hydrogen production and use, noting that it takes roughly three units of renewable electricity to generate one unit of motion at the wheels due to energy losses in electrolysis, compression, storage, and reconversion. Additionally, hydrogen systems are expensive to maintain and have higher fuel costs compared to diesel when all factors are considered. Beyond economics

Researchers at Japan’s National Institute for Materials Science (NIMS) have developed a cost-effective, high-performance catalyst for hydrogen storage by modifying a common mineral called green rust, an iron hydroxide. This catalyst enables the release of hydrogen from sodium borohydride (NaBH4) through hydrolysis at room temperature without relying on expensive precious metals like platinum, addressing a major challenge in hydrogen fuel technology. The modification involves treating green rust particles with copper chloride, creating nanoscale copper oxide clusters that serve as highly active sites for hydrogen production. The catalyst also harnesses solar energy, with the green rust structure absorbing sunlight and transferring energy via copper clusters to enhance the hydrolysis reaction’s efficiency and hydrogen generation rate. Performance tests showed that this catalyst achieves hydrogen production rates comparable to or exceeding those of traditional precious metal catalysts, while maintaining durability over repeated use. Its room-temperature operation, simple production, and compatibility with existing hydrogen systems position it as a promising solution to advance clean hydrogen energy, particularly when combined with

Researchers at the University of Toronto have developed a lizard-scale-inspired design for flow field plates in proton exchange membrane (PEM) hydrogen fuel cells, significantly improving water management and power density. Traditional fuel cells suffer from water flooding in the gas diffusion layers (GDLs), which blocks oxygen delivery to reaction sites and reduces performance. By mimicking natural structures such as desert lizard scales and leaf veins—both of which channel water directionally with minimal energy—the team carved auxiliary drainage channels into the flow field plates. This biomimetic approach enables more efficient water removal while maintaining oxygen flow, addressing a critical bottleneck in fuel cell operation. The study, published in Applied Energy and led by Eric Chadwick, demonstrated a 29.1% increase in peak power density, achieving 639 milliwatts/cm² compared to 495 milliwatts/cm² in conventional designs. The innovation departs from the traditional corrugated land-channel structure, where water accumulates under solid lands and obstructs oxygen

Researchers at Kumamoto University in Japan have developed a novel solid electrolyte membrane for hydrogen fuel cells using abundant natural montmorillonite clay minerals. This flexible membrane, fabricated from monolayer silicate nanosheets, exhibits dual functionality: it offers high proton conductivity across a wide temperature range (from -10°C to 140°C) and acts as a superior hydrogen gas barrier, blocking hydrogen over 100 times more effectively than the current industry standard, Nafion. These properties enable safer, more efficient, and longer-lasting fuel cells that operate well in extreme heat and cold, overcoming the limitations of traditional fuel cells that require high operating temperatures above 500°C. The new clay-based electrolyte achieves proton conductivities comparable to or exceeding polymer-based electrolytes, with values such as 2.3×10⁻³ S/cm at 10°C and 8.7×10⁻³ S/cm at 140°C under full humidity. In practical testing, fuel cells using this membrane demonstrated strong performance

The BloombergNEF 2025 Factbook on zero emission commercial vehicles reveals a decisive market shift favoring battery-electric trucks over hydrogen fuel cell trucks in global freight transportation. In the first half of 2025, nearly 90,000 zero emission trucks were sold worldwide, with 97% being battery-electric, while fuel cell truck sales halved to about 1,000 units. China leads this trend, having sold close to 80,000 electric trucks in six months—more than double 2023’s total—driven by strong battery supply chains, incentives, and cost reductions. Conversely, China’s hydrogen truck market is shrinking despite subsidies, indicating hydrogen’s failure to compete. Europe shows a similar pattern, with electric truck sales growing over 50% year-on-year, supported by infrastructure investments and zero emission zones, while hydrogen truck programs face delays and reduced ambitions. The EU’s binding infrastructure targets further cement battery dominance. In contrast, the U.S. market lags significantly,

The North American Council for Freight Efficiency’s (NACFE) "Run on Less" initiative showcases a diverse range of freight trucks, including battery electric vehicles (BEVs), renewable diesel tractors, natural gas trucks, and hydrogen fuel cell units. This variety reflects the real-world choices fleets are making, but it also raises questions about why many trucks do not outperform others in terms of cost efficiency or greenhouse gas emissions when normalized for comparable metrics. NACFE aims to clarify this by emphasizing two key metrics upfront: cost per mile (the energy cost to move a loaded truck over a specific route) and well-to-wheel emissions per mile (greenhouse gases from energy production through use, normalized to 1,000 miles). These metrics are contextualized by factors such as duty cycle, location, and energy source characteristics, including grid carbon intensity and fuel production methods. The article details how these metrics are calculated for different truck types, incorporating realistic efficiencies, energy losses, and emissions from fuel production and use. For

South Korea's ambitious 2019 plan to become a global leader in hydrogen transportation, highlighted by a government pledge to replace all 802 police buses with hydrogen fuel cell models by 2028, has largely faltered. Despite significant investment—over $7.2 million spent—and initial enthusiasm from Hyundai and government ministries, only 16 hydrogen police buses are expected to be operational by the end of 2025. The police have refused to purchase more due to unreliable fueling infrastructure, with many hydrogen stations having limited hours, rationing fuel, or frequent outages. This unreliability undermines the operational readiness required for police deployment, effectively ending the program. The failure of South Korea’s hydrogen bus initiative reveals deeper challenges in the country’s hydrogen transportation strategy. Hydrogen buses remain more expensive to buy and operate than battery electric alternatives, with costly and often unreliable fueling stations. Safety concerns also surfaced, notably a December 2024 explosion of a hydrogen bus that injured several people. These practical issues contrast sharply with

BMW has reaffirmed its commitment to hydrogen fuel cell electric vehicles (FCEVs), signaling plans to move toward series production despite challenges faced by the technology in the zero-emission mobility market. While battery electric vehicles (BEVs) currently dominate due to advantages in cost, fuel availability, and convenience, fuel cells still offer benefits in range and refueling time. BMW’s approach contrasts with companies like Stellantis, which recently discontinued its fuel cell development for light-duty commercial vehicles, citing limited hydrogen infrastructure, high costs, and weak consumer incentives. Stellantis, however, has not abandoned hydrogen entirely and may revisit the technology in the 2030s. BMW’s fuel cell efforts date back to a 2014 prototype and a 2023 limited iX5 demonstration fleet developed with Toyota’s fuel cell technology. The latest development is a third-generation fuel cell platform co-developed with Toyota, designed for both commercial and passenger vehicles.

The article from CleanTechnica highlights a critical and often overlooked limitation in the widespread adoption of hydrogen fuel cell vehicles: the scarcity of platinum, an essential metal for proton exchange membrane (PEM) fuel cells. Platinum acts as a catalyst in these fuel cells, facilitating key chemical reactions necessary for their operation. However, global platinum supply is limited to about 250 to 280 tons annually, with significant portions already allocated to automotive catalytic converters, jewelry, and industrial uses. The market is currently in deficit, with shortages and rising prices, posing a severe constraint on scaling hydrogen fuel cell technology for mobility. The article further explains that while some hydrogen technologies, like certain electrolysers, can avoid or reduce platinum use by employing alternative materials, fuel cell vehicles lack such flexibility. The demand for platinum in fuel cell stacks is substantial: a typical passenger car requires 13 to 18 grams, heavy trucks 120 to 180 grams, and buses 40 to 90 grams. If just 10%

The article "Hydrogen Mobility vs. Platinum Reality" from CleanTechnica highlights significant challenges facing hydrogen fuel cell technology in transportation, particularly due to its reliance on platinum. Alstom’s hydrogen-powered Coradia iLint trains, which use fuel cells supplied by Cummins, have faced operational setbacks in Germany, with many trains reverting to diesel because replacement fuel cells are unavailable. This issue is not merely a supply chain problem but points to a deeper structural constraint: the critical dependence on platinum, a scarce and expensive metal essential for the fuel cells’ catalytic function. Each train’s fuel cells require about 0.2 kg of platinum, costing roughly $8,700 at current prices, which is a significant factor given the limited global platinum production. Platinum’s unique catalytic properties enable the fundamental reactions in proton exchange membrane (PEM) fuel cells, splitting hydrogen molecules and facilitating the combination of oxygen, protons, and electrons to produce electricity efficiently and durably. This indispensable role means fuel cells cannot

The International Council on Clean Transportation (ICCT) recently published a lifecycle assessment (LCA) report on road vehicle decarbonization in Europe that positions hydrogen fuel cell electric vehicles (FCEVs) as a climate-friendly alternative comparable to battery electric vehicles (BEVs). However, the report has been criticized for focusing on passenger cars in 2025—a segment where hydrogen vehicles have effectively failed in Europe—and ignoring the current market reality where electric buses and heavy goods vehicles dominate. Critics argue that including a "dead segment" like passenger FCEVs misrepresents the state of hydrogen technology and its viability compared to BEVs. More importantly, the ICCT report is faulted for not adequately accounting for hydrogen leakage throughout the supply chain and for using the 20-year global warming potential (GWP20) metric instead of the more common 100-year metric (GWP100). Hydrogen leakage occurs at multiple stages—electrolysis, liquefaction, pipeline transmission, trucking, refueling,

Stellantis, a major global automaker and early advocate for hydrogen fuel cell electric vehicles (FCEVs) in light commercial transport, has recently retreated from its hydrogen mobility ambitions. Despite launching eight new hydrogen-powered van models in early 2024 and investing heavily—including a 33% stake in French fuel cell supplier Symbio—Stellantis faced harsh economic realities. The company projected producing up to 10,000 hydrogen vans by the end of 2024, banking on supportive European policies and infrastructure. However, the high costs of hydrogen vehicles, which remained about 80% more expensive than comparable battery-electric models even after significant price cuts, proved prohibitive. Former CEO Carlos Tavares publicly acknowledged these challenges, and his departure later in 2024 underscored strategic uncertainties around hydrogen. Stellantis’ withdrawal highlights persistent structural issues with hydrogen mobility, notably the failure of promised European hydrogen refueling infrastructure to materialize.

The article discusses recent developments in off-grid electric vehicle (EV) charging stations amid regulatory and infrastructure challenges. Despite the temporary suspension of the US NEVI program by President Trump, a judge has mandated its continuation. Meanwhile, startups like California-based L-Charge, in partnership with Epic Charging, are innovating by deploying transportable, off-grid EV chargers that do not rely on traditional electrical grid connections. These chargers use generators fueled by renewable natural gas (RNG) or flare gas, enabling rapid installation at locations such as motels, restaurants, and retail outlets without the need for extensive electrical infrastructure upgrades. L-Charge’s off-grid charging stations offer a practical solution especially for heavy-duty fleet vehicles, providing a faster pathway to electrification and reducing reliance on diesel fuel. The company targets both public use and fleet owners, allowing a single installation to serve multiple needs and reduce tailpipe emissions in communities. This approach, while not a complete decarbonization solution, helps mitigate diesel pollution and supports zero

The article discusses the challenges and ongoing efforts to develop green hydrogen production in the United States amid political and policy headwinds. Despite the Trump administration’s efforts to curtail renewable energy initiatives, including the termination of the Biden-era Hydrogen Hubs program that aimed to diversify hydrogen sources toward sustainable methods like electrolysis from water and biomass, investor interest in green hydrogen remains resilient. Green hydrogen, produced via electrolysis powered by renewable energy, is seen as a critical component for decarbonizing key industrial sectors such as refining, metallurgy, and fertilizer production, as well as for fuel cells in transportation and electricity generation. A notable example of continued investment is the UK-based firm Hoku Energy Ltd., which plans to establish green hydrogen facilities in the US, leveraging existing infrastructure and renewable energy sources. The article highlights the case of Cadiz, Inc., a California-based water resources company with extensive land holdings, which is developing a clean energy campus incorporating green hydrogen production powered by solar energy.

The article from CleanTechnica critically examines the current state and challenges of hydrogen fuel cell technology in transportation, highlighting the gap between its appealing theoretical benefits and practical realities. It emphasizes two main issues: first, hydrogen is not inherently zero-emission unless produced via renewable energy sources like electrolysis powered by green electricity; otherwise, its production from fossil fuels generates significant carbon dioxide. Second, the cost of producing green hydrogen remains prohibitively high, making widespread commercial adoption difficult. Advocates for hydrogen often overlook these barriers, engaging in what the article terms "magic realism"—a hopeful but unrealistic belief in hydrogen’s near-term viability as a clean fuel. Despite these challenges, Toyota Motor Europe, in partnership with VDL Group, has introduced four heavy-duty fuel cell trucks operating between freight terminals in Belgium, France, Germany, and the Netherlands. These 40-ton trucks reportedly match diesel trucks in performance, offering up to 400 km range per refueling and zero tailpipe emissions, emitting only water vapor.

Hype, once a leading hydrogen taxi service in Europe, has abandoned hydrogen technology and shifted exclusively to electric vehicles, reflecting the broader global failure of hydrogen-powered transportation ventures. Founded in Paris in 2015, Hype initially expanded rapidly by leveraging substantial subsidies from French government agencies, regional authorities, and the European Union. Key funding came from the French Environment and Energy Management Agency (ADEME), the Île-de-France region, and the EU’s Fuel Cells and Hydrogen Joint Undertaking (FCH JU), which supported both vehicle acquisition and the costly hydrogen refueling infrastructure. This extensive public funding masked the underlying economic challenges of hydrogen taxis, which remained prohibitively expensive without subsidies. A critical factor in sustaining Hype’s operations was its partnership with Toyota, which provided free hydrogen fuel with leased Mirai fuel cell vehicles for several years, eliminating a major operational cost and creating a misleading impression of economic viability. By 2020, Hype operated Europe’s largest hydrogen taxi fleet and was prominently featured in

Toyota is set to launch the world’s first fully connected, self-contained “robot city” called Woven City at the base of Mount Fuji, Japan, in fall 2025. Situated on the 175-acre former Higashi-Fuji plant site in Shizuoka Prefecture, about 140 kilometers southwest of Tokyo, this experimental metropolis will serve as a real-world testbed for future mobility, smart infrastructure, and sustainable living. Initially housing 100 residents—mainly Toyota engineers and their families—the population is expected to grow to 360 in the first phase, with a long-term goal of 2,000 inhabitants. The city’s residents are divided into “Inventors,” who develop new technologies, and “Weavers,” who provide user feedback. Central to the city’s design is Toyota’s autonomous electric vehicle platform, the e-Palette, which will operate alongside an underground logistics network and dedicated surface lanes for pedestrians, slower mobility devices, and autonomous vehicles. Beyond mobility, Woven City emphasizes sustainability and resilience through a hydrogen fuel cell energy grid supplemented by solar panels, water recycling, and advanced waste management. Smart homes equipped with robotics and AI will monitor health, manage energy, and optimize daily life, while the entire urban system is interconnected via sensors and AI to create a living digital operating system. The city functions both as a simulation environment and a functioning habitat, enabling direct testing of smart infrastructure technologies. Although not open to tourists initially, Toyota plans to allow public access starting in 2026. Ultimately, Woven City aims to serve as a scalable model for future urban planning worldwide, demonstrating how public-private partnerships can foster next-generation technologies amid growing climate and security challenges.
