SpaceX alums find traction on Earth with their Mars-inspired methane-to-CO2 tech

General Galactic, founded by Mattison and Neise, develops reactors producing methane from carbon dioxide as a natural gas alternative. Their pilot system generates 2,000 liters daily, with plans to expand. The company aims to sell methane for industrial use rather than heating or energy. They recently raised $8 million in seed funding and plan to deploy modules in 2025. While potentially having a lower carbon footprint than fossil fuels, concerns about methane leaks persist. General Galactic is also exploring other hydrocarbons for future transportation applications.
