UK firm hits first plasma milestone in fusion space propulsion
UK-based Pulsar Fusion has reached a significant milestone in developing its Sunbird fusion propulsion engine by successfully generating its first plasma within the engine's exhaust system. This achievement, demonstrated live at the MARS Conference in California, marks an early but crucial step toward creating nuclear fusion-based engines designed for high-speed space travel. The test validated the physical design of the fusion exhaust system, where charged particles are confined and accelerated using electric and magnetic fields. Initially, krypton gas was used as a propellant due to its favorable ionization properties, allowing researchers to study plasma behavior under controlled conditions. Looking ahead, Pulsar Fusion plans to advance the technology by measuring thrust and exhaust velocity with specialized instruments and collaborating with the UK Atomic Energy Authority to address challenges related to neutron radiation damage in reactor materials. The company aims to enhance the system with high-temperature superconducting magnets to achieve stronger magnetic fields and higher plasma densities, as well as explore advanced heating methods. Ultimately, Pulsar seeks to develop aneutronic fusion fuel

Zap Energy, a US-based fusion engineering company, has achieved a significant milestone with its Century test platform by operating over 100 plasma shots at a frequency of 0.2 Hz, delivering 39 kilowatts of power to the plasma chamber. This performance marks a 20-fold increase in sustained average power since the platform’s commissioning in 2024. The Century platform is designed to test the integration of key subsystems for a potential commercial fusion power plant, including a repetitive pulsed power system, durable electrodes, and liquid metal walls that absorb and transfer plasma energy. Importantly, the platform does not use fusion fuel or produce fusion reactions but provides crucial operational data on the system components. Zap Energy’s unique approach, called sheared-flow-stabilized (SFS) Z-pinch, confines and compresses plasma using a pulse of electricity and the plasma’s own magnetic field, avoiding the need for superconducting magnets or high-intensity lasers. Recent upgrades to the platform include a liquid metal

SOSV, a venture capital firm, is making a significant bet on plasma technology, planning to invest in over 25 plasma-related startups within the next five years. The firm is also launching a new Hax lab in collaboration with the New Jersey Economic Development Authority and the U.S. Department of Energy’s Princeton Plasma Physics Laboratory to foster innovation in this space. Plasma, a state of matter created by compressing fuel until atoms fuse and release energy, holds promise far beyond fusion energy alone. Duncan Turner, SOSV’s general partner, highlights that the best applications of plasma are yet to be discovered, indicating vast untapped potential. Beyond fusion, SOSV has already invested in companies like Yplasma, which utilizes plasma actuators for cooling data center chips and optimizing airflow over wind turbine blades. Plasma’s role in semiconductor manufacturing could lead to breakthroughs in materials and processes, while plasma thrusters offer more fuel-efficient propulsion for spacecraft. Additionally, plasma technology could enable the production of valuable chemicals such as ammonia

Researchers at the University of Sydney have developed a novel plasma-based technology that produces ammonia directly from air using electricity and artificial lightning, offering a cleaner, decentralized alternative to the traditional Haber-Bosch process. Unlike the conventional method, which requires high heat, pressure, and fossil fuels, this new two-step approach excites nitrogen and oxygen molecules in air via plasma and then converts them into gaseous ammonia through a membrane-based electrolyzer. This innovation bypasses previous inefficiencies where ammonia was only produced in liquid ammonium form, enabling a more straightforward and scalable production of green ammonia, particularly beneficial for rural or off-grid areas. Ammonia is critical not only for fertilizer production, supporting nearly half of global food supply, but also as a potential carbon-free fuel and hydrogen carrier, with industries like shipping exploring its use to reduce emissions. The Sydney team’s plasma-electrolysis method has demonstrated viability in energy efficiency and scalability for the plasma component, though further improvements are needed for the electrolyzer’s efficiency.
