PlasmaLeap Technologies
PlasmaLeap Technologies is a Sydney-based cleantech company building modular, non-thermal plasma reactors that make ammonia, nitric acid, fertiliser and hydrocarbon eFuels from just air, water and renewable electricity. Spun out of the University of Sydney in 2019, its 'lightning-mimicking' process replaces the century-old, fossil-fuelled Haber-Bosch route with room-temperature, on-site chemical production. Its eNFix containerised units let farmers make green nitrogen fertiliser at the farm gate, cutting emissions and supply-chain dependence. The company raised roughly A$30 million in a Series A led by the Gates Foundation, Investible and Yara Growth Ventures to build first-of-a-kind fertiliser hubs in New South Wales and Tasmania.
1s1 Energy
1s1 Energy is a materials-science company making green hydrogen cheaper by rethinking the guts of the electrolyzer. Instead of the fluorinated (PFAS) membranes the industry has leaned on for decades, 1s1 builds boron-based proton-exchange membranes and electrochemical components that its partners report can produce a kilogram of hydrogen using roughly 70% of the energy of incumbent devices - already hitting efficiency targets the U.S. Department of Energy set for 2031. Founded in 2019 and run out of Portola Valley, California with labs in Lisbon and Campinas, Brazil, the company sells core components to electrolyzer and fuel-cell makers and runs pilots with utilities and heavy industry.
Addis Energy
Addis Energy is a Somerville, Massachusetts climate-tech company turning the Earth's subsurface into a chemical reactor to make ammonia. By injecting nitrate-bearing water into iron-rich underground rock, its process uses natural heat and pressure to convert nitrogen into ammonia without hydrogen feedstock, added electricity, or CO2 emissions. Spun out of MIT research and paired with deep oil-and-gas engineering experience, the company aims to produce clean ammonia - a fertilizer and potential fuel behind more than 1% of global emissions - at a fraction of conventional cost.
TalusAg
TalusAg, the agriculture arm of Talus Renewables, builds modular, containerized systems that make green ammonia on-site from only water, air, and renewable electricity. By shrinking a process that normally requires billion-dollar plants into a shipping container, the company lets farmers and industrial users produce their own carbon-free fertilizer and fuel locally, cutting costs and supply-chain risk.
