Lukera Energy converts stranded methane and industrial seawater into carbon-negative methanol for ships using a patented nanobubble electrocatalytic reactor that is seven times more energy efficient than conventional synthesis. Our modular 1-ton-per-day units cut levelized costs below 400 dollars per ton, eliminate the need for green hydrogen, and slash well-to-wake emissions by 120 percent compared with heavy fuel oil. Backed by LOIs for pilot deployments, we aim to commercialize 100-ton-per-day plants by 2030, attacking a 50 billion dollar marine fuel market.
