About Echogen

Innovation that rolls up its sleeves.

We’re a team of hands-on engineers, builders, and problem-solvers designing thermal energy systems that perform where others fall short. Echogen exists to deliver real solutions to the grid’s toughest challenges, with rigor, humility, and staying power.

Born from engineering. Built for impact.

Echogen was founded with a clear goal: to convert
waste heat into clean, usable power using smarter thermodynamics. We saw untapped energy all around us, in industrial facilities, power plants, and remote sites, and knew there had to be a better way to put it to work. What started as a focused technical challenge became a broader mission to make advanced thermal systems that are rugged, efficient, and ready for real-world conditions.

From the beginning, we’ve followed the physics. Our team set out to solve energy challenges by engineering, not by chasing trends. We’ve stayed skeptical of hype, focused on validation, and committed to the slow, iterative work of building systems that perform. The time for long-duration storage and efficient heat recovery is now, and we’ve spent the last decade getting ready for it.

What
drives us.

Engineering first

We believe great systems start with sound physics, not flashy promises. Every design we build is grounded in science and shaped by rigorous testing.

Solve what matters

We work on problems that make a difference: cleaner grids, lower emissions, and more resilient infrastructure. If it doesn’t solve a real-world need, we’re not interested.

Build what lasts

Our systems are made to endure. We favor reliability over complexity, durability over trendiness, and performance over perfection.

Respect the work

We value deep knowledge, collaborative problem-solving, and a shared commitment to excellence. No egos. No shortcuts. Just people who care about getting it right.

Lead Engineer on PTES

“As a college intern at Echogen, I was tasked with developing foundational project documentation that would prove essential throughout the entire project life cycle. After my internship, I joined the team 
full-time and became a key contributor to the commissioning and testing of a first-of-its-kind, megawatt-scale CO₂ waste heat recovery system. Today, as a Senior Engineer, I lead projects that push the boundaries of what’s possible in CO₂ based turbomachinery and systems. The work demands persistence, creativity, and patience, and that’s exactly what makes it rewarding. At Echogen, you’re not just part of the process, you help shape it.”

Our values, put to work.

At Echogen, our values aren’t slogans. They’re how we operate. We move fast, think deep, and build systems that work in the real world. With a high-density team of curious, straight-talking engineers, we focus on pure, no-nonsense engineering that performs.

  • Technical excellence with dirty hands
    We don’t just model. We build, test, and refine every system ourselves.
  • Pragmatic innovation, engineered to last
    Our ideas are ambitious, but our approach is grounded. We solve for reliability, cost, and deployment.

  • Progress without pretense
    We believe in direct answers, common-sense thinking, and doing the work. Our team doesn’t overpromise. We overdeliver.
