MIT spinout Osmoses has developed a new class of polymer membranes that could dramatically reduce the colossal 10 to 15 percent of the world’s total energy consumption currently devoured by industrial chemical separation. Founded by former MIT researchers, the company’s technology filters gases with unprecedented selectivity, offering a powerful, energy-efficient alternative to the century-old practice of heat-based distillation.
Imagine the energy required to boil a massive pot of water, then scale that up to an industrial level where separating chemicals and fuels involves heating vast quantities to extreme temperatures every single day. That’s the reality for industries from petrochemicals to pharmaceuticals, and it’s a massive, often overlooked, drain on global energy resources. Francesco Maria Benedetti, CEO and co-founder of Osmoses, along with co-founders Katherine Mizrahi Rodriguez ’17, PhD ’22, MIT professor Zachary Smith, and Holden Lai, asked a critical question: What if we could separate these vital materials without all that heat?
The answer lies in their breakthrough polymer membranes. Gases, composed of some of the tiniest molecules, have historically been the most challenging substances to separate efficiently. Traditional thermal processes are clunky and energy-hungry. According to a MIT News report on the technology, Osmoses’ solution uses a innovative class of materials called hydrocarbon ladder polymers. These polymers have tunable molecular structures that act like incredibly precise sieves, allowing target molecules to pass through while blocking others, all without changing the temperature.

“Chemical separations really matter, and they are a bottleneck to innovation and progress in an industry where innovation is challenging, yet an existential need,” Benedetti told MIT News. “We want to make it easier for our customers to reach their revenue targets, their decarbonization goals, and expand their markets to move the industry forward.”
The impact potential is staggering. The company cites a study in the journal Nature which found that replacing thermal distillation in just the U.S. could slash annual energy costs by $4 billion and prevent 100 million tons of carbon dioxide emissions. For industrial customers, this isn’t just about going green—it’s a practical business upgrade. The membrane systems are more compact, reducing the physical footprint of separation plants, and they offer lower upfront capital costs compared to building massive thermal distillation columns.

The journey from lab bench to real-world solution began in Professor Smith’s lab at MIT, where fundamental research into polymer materials slowly yielded record-breaking results. In 2022, key research underpinning the technology was published in the prestigious journal Science. Rather than wait for industry to notice, the team decided to lead the commercialization charge themselves. After winning the MIT $100K Entrepreneurship Competition in 2021, they embarked on a mission to validate their technology at scale.
Today, Osmoses is moving beyond the gram-scale experiments of the lab toward pilot projects that prove its value. They are working with a large North American utility to upgrade biogas at a landfill—a process that separates CO2 from methane to create renewable natural gas. Another pilot at a dairy farm targets the same application. “In the near term, our goal is to validate this technology at scale,” Benedetti stated.

Further pilots showcase the technology’s versatility. In a partnership with the U.S. Department of Energy, Osmoses is working to extract valuable helium from underground wells. “Helium is a scarce resource… and our membranes’ high performance can be used to extract small amounts of it,” explained Mizrahi Rodriguez. This is crucial for everything from MRI machines to the semiconductor industry that powers the AI revolution.
Looking ahead, the team envisions their membranes tackling everything from carbon capture to purifying natural gas. By removing the thermal bottleneck, Osmoses isn’t just saving energy; it’s aiming to redefine the backbone of heavy industry, making essential separations smarter, smaller, and sustainable.
