Michael Alexander

Michael Alexander is the co-founder and CEO of Addis Energy, a Somerville, Massachusetts startup turning the Earth's crust into a chemical reactor to make clean ammonia. A chemical engineer who spent more than eight years refining oil at Shell and Marathon Petroleum, he discovered geologic hydrogen at Harvard Business School and teamed up with classmate Charlie Mitchell and MIT professors Iwnetim Abate and Yet-Ming Chiang to commercialize a process that stimulates ammonia production from iron-rich rock underground. In December 2025 Addis raised an oversubscribed $8.3M seed round, bringing total funding to $17.3M.
