About Lazarus Energy

Lazarus Energy (Lazarus Energy Systems) is a Hawthorne, California deeptech company founded by CEO George Kitromelides and CTO Luke Malcolm—former Anduril propulsion teammates with experience at Siemens Energy, Williams International and Ursa Major—that builds containerised modular power plants using supercritical CO₂ (sCO₂) Brayton-cycle turbines for on-site data-center and industrial electricity. Supercritical CO₂ above ~31°C and 73.8 bar behaves with liquid-like density and gas-like flow, enabling much smaller turbomachinery than steam or conventional gas turbines; Lazarus designs heat-source-agnostic modules that can convert natural gas, biogas, advanced nuclear, concentrated solar or other heat into dispatchable power, ship in a standard container, assemble in weeks without custom site buildouts, and use direct air cooling so the plant does not require water for cooling. The firm is developing a megawatt-class demonstrator aimed at first paid customer deployment as AI load outpaces grid interconnection queues and legacy turbine lead times stretch years. In 2026 Lazarus raised an oversubscribed $16 million seed led by 8VC, with Marlinspike, DST Global, Neuron Power Ventures, Relentless, Fifty Years and Side Door Ventures, after earlier support via the 50/50 Accelerator.
