First Mode started by removing the diesel engine from a colossal mining truck and replacing it with a hydrogen fuel cell powerplant. A world-first, and the world’s largest. But we’re not stopping there. We are also working on providing critical mine site infrastructure for hydrogen production, battery recharging, and hydrogen refueling. Today, we’re starting at the source, the mining industry, and tomorrow the larger supply chain, to completely eliminate the use of diesel and speed the clean energy transition. We hope you’ll join us in building a brighter future for people and planet.
