We harness supercritical CO₂, a state where carbon dioxide acts like a liquid and a gas, to create efficient, reliable energy systems that cut emissions, lower costs, and boost operational stability. Our technology powers three core solutions: long-duration energy storage that turns electricity into heat using affordable materials; high-temperature sCO₂ heat pumps for industrial decarbonization; and waste heat recovery systems that turn lost heat into clean power. Backed by proven science and hard-earned expertise, our systems deliver real value. No rare earths. No gimmicks. Just intelligent energy that works.
Echogen’s Pumped Thermal Energy Storage (PTES) system stores electricity as heat in abundant, low-cost materials like water and concrete, using precision-engineered CO₂ cycles to charge and discharge power with high efficiency. Built by engineers who design for durability and scale, our long-duration storage delivers reliable, dispatchable energy for hours or even days. With no performance degradation, no rare earths, and a modular footprint, PTES helps balance renewables, strengthen grid resilience, and lower the cost of clean power.
Echogen’s supercritical CO₂ heat pumps deliver high-temperature steam and heat to industrial processes, replacing fossil-fueled boilers with efficient, all-electric systems that cut emissions and reduce operating costs. Engineered from the ground up by a team that builds what they design, our heat pumps push the limits of thermodynamics to deliver clean heat at scale. With no combustion, compromise, or wasted energy, we help industries decarbonize confidently, strengthening their bottom line while staying ahead of shifting regulations and volatile energy markets.
Echogen’s supercritical CO₂ waste heat recovery systems convert high-grade industrial waste heat into clean, dispatchable power with no added fuel or emissions. Our compact, closed-loop systems integrate seamlessly into existing operations and are built on advanced thermodynamics and precision turbomachinery. Designed, tested, and refined by engineers who know how to turn waste into working power, they help industrial facilities reduce energy costs, shrink their carbon footprint, and get more from what they already produce.
