Critical Energy Systems

Critical Energy Systems designs and builds modular geothermal power plants to deliver dispatchable 24/7 clean electricity. Its Cascade system uses factory-assembled, shipping-container modules that can be moved to remote sites and operated individually or in parallel to match local resources. Each module provides multi-megawatt output and relies on a closed-loop geothermal cycle with heat exchange, working fluid circulation, and turbine-driven power generation. The approach allows faster, more flexible deployment than traditional geothermal facilities. The company differentiates itself with aerospace-inspired engineering, a proven testbed (over 50 kW generated in a demo), and a focus on cost-effective, scalable modules that can be deployed rapidly. The goal is to accelerate adoption of low-cost, dispatchable geothermal energy to provide reliable, carbon-free power at scale.
