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.
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 sand, water, or 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 keeping the grid humming.
PTES is a closed-loop, high efficient system designed to last decades. Fewer moving parts. Lower costs. Smaller footprint. More uptime. And, unlike batteries, it does not degrade over time.
As demand for power grows, so does the need for storage that can keep up—for any generation source, from solar to fission. Echogen delivers 8-100 hours of energy storage with flexible charge and discharge cycles, no geographic limitations, and zero fire risk. Just clean, durable tech that pulls its weight—and strengthens the grid.
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.
We build the only heat pumps on the market that can efficiently deliver steam and process heat up to 400°C—all from ambient sources. Powered by supercritical CO₂, our systems are compact, efficient, and built to get more out of less—without wasting a single degree.
Echogen’s patented technology uses the safest refrigerant available—and is uniquely suited for integration with thermal energy storage. When electrification is the name of the game, a system optimized for high heat, high return is the only answer for delivering safe, scalable decarbonization.
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.
Zero water. Minimal footprint. And a clear path to decarbonizing heavy industry—no overhaul, no hype, just smart systems built by engineers who measure twice, cut once, and don’t mind breaking a sweat.
Whether it’s waste heat, advanced nuclear, or innovative geothermal, our power generation cycles convert high heat into valuable electricity with serious efficiency and reliability. Our Heat to Power solution is engineered for maximum performance and seamless integration, while delivering results that speak for themselves.
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, we’ve got the calluses to prove it. This isn’t fluff, it’s real hardware that solves real problems.
