At Echogen, we don’t just talk innovation—we weld it, wire it, and test it until it works. With almost two decades of supercritical carbon dioxide (sCO₂) development under our belts (and under our fingernails), we build energy systems that solve real-world problems. No vaporware. No whiteboard fantasies. Just applied expertise, built to scale.
Decades of performance. Minimal maintenance. No chemical breakdown. We build systems that stick around, not ones that age out every five years.
Compact systems. No water. No global material scavenger hunt. Just clean thermodynamics, engineered to plug in and perform.
After a decade of lab work, field pilots, and real-world builds with serious partners, our track record speaks for itself. This isn’t fluff. It’s real hardware that solves real problems.
Our solutions solve problems, integrate with partners, and are designed for real-world conditions from day one.
Electricity in, electricity out. Our Pumped Thermal Energy Storage (PTES) system uses a CO₂ heat pump to charge and a heat engine to discharge—storing electricity as thermal energy in low-cost, durable materials like water and concrete. It’s engineered for long-duration performance with no rare earth metals, no degradation, and no need for augmentation. Just proven thermodynamics and turbomachinery doing what they do best—balancing renewables, flattening peaks, and providing inertia and resiliency to keep the grid humming.

Need high-grade heat or steam without the boiler baggage? Our supercritical CO₂ (sCO2) heat pump delivers clean, efficient heat powered by electricity. Designed for industrial processes that demand serious temperature (X–Y °F), it’s a drop-in solution that eliminates emissions without disrupting operations.
From Waste Heat Recovery (WHR) to power cycles for advanced nuclear reactors, our sCO₂ heat engines convert heat into power more efficiently than traditional steam systems — no extra fuel, no added emissions, no wasted energy. Our compact systems slot into existing operations or designs without skipping a beat.
