Membrane Technology and Research Raises $27M Series B to Scale Gas Separation and Carbon Capture Systems

Membrane Technology and Research just pulled a quiet power move out of Newark, and if you blink you miss the weight of it. 40+ years in the game, hundreds of systems deployed, and now a fresh $27M Series B to remind everyone that patience and precision still print results. Climate Investment led the round, Hartree Partners stepped in alongside, and the signal is clear. This is not a science project. This is scale knocking on the door.

Credit where it is due. Congratulations to Brett Andrews, CEO, for stepping into a moment that demands both operational grit and long memory. And respect to Dr. Richard W. Baker, who started this whole thing back in 1982 when membrane tech sounded more like a lab experiment than a commercial backbone. Some companies chase trends. Others become the infrastructure those trends depend on.

Membrane Technology and Research lives in that second category. They build polymer membrane systems that separate gases at industrial scale. Natural gas, hydrogen, CO2, the stuff most people never see but every economy runs on. Their Polaris platform pushes into carbon capture, targeting real volume, real impact, not just conference talk. At Dry Fork Station, the design ambition is up to 3M tonnes of CO2 per year with at least 90% capture. That is not theory. That is engineering with consequences.

So why does this round matter now. Because the market is done entertaining science fair projects. Industrial buyers want solutions that bolt onto existing systems, behave predictably, and do not require a PhD to operate. Membrane Technology and Research has been refining that play for decades. Modular, compact, integratable. Words that do not trend on social, but they close deals in boardrooms.

Climate Investment is not placing casual bets. They lean into decarbonization with a mandate tied to real industry. Hartree Partners understands energy markets at a level where inefficiency is expensive and speed matters. When both show up, it is less about hype and more about throughput.

The takeaway is simple, but not easy. Longevity plus technical depth plus timing equals leverage. Membrane Technology and Research did not rush to be seen. They built until the market had no choice but to look. Now the capital follows the competence. And somewhere between polymer science and project finance, a company that started with membranes is now separating signal from noise in one of the most crowded conversations in tech.
