- Ukraine's 3rd Army Corps commander Andrei Biletsky set a 30% infantry-replacement goal with drones and ground robots for 2026, with the figure projected to reach as high as 80% in the future.
- Sesame Solar and Heven AeroTech deployed a mobile green hydrogen refueling system for Heven's Z-1 fuel cell UAVs, with a single person assembling the nanogrid in about 15 minutes and drones deployable in five minutes without tools.
- First Hydrogen and Exodus Actuation Solutions announced an unmanned ground vehicle combining solar, batteries, and fuel cells, designed for military field support such as drone launch and refueling, transport, and security, with civilian applications as well.
- First Hydrogen established a First Nuclear branch to enlist small modular reactors (SMRs) for electrolysis, though the source notes the first US SMRs are not expected to produce electricity until 2030, barring typical nuclear cost overruns.
- US prospects for the green hydrogen industry dimmed after the Regional Clean Hydrogen Hubs program was scrapped, though a Minnesota ag tech startup is establishing wind- and solar-powered green ammonia fertilizer facilities to stabilize costs.
- S&P Global (2022) anticipated that climate change-exacerbated water shortages pose near- and longer-term performance risks to nuclear and hydropower plants, a factor complicating the SMR-based hydrogen plan.
Why it matters: Military demand has become a proving ground for green hydrogen fuel cells that have struggled for civilian adoption, echoing the Air Force's earlier role in seeding the solar industry. Fuel cells offer longer flight times and larger payloads than batteries for combat drones. With the US Regional Clean Hydrogen Hubs program curtailed and US SMRs not producing electricity until 2030, defense applications now carry the heaviest commercialization weight for fuel cell technology.
