While serving as an entrepreneur in residence at the University of Washingtons Clean Energy Institute, renewable energy innovator John Plaza was looking for another company to run. He found one after meeting Dr. Greg Newbloom.

Newbloom, a chemical engineer, had developed alongside UW Professor Lilo Pozzo a technology that uses silica gel a nontoxic material often packaged with new shoes and beef jerky to create a new class of inexpensive, flexible ceramic membranes that separate molecules from liquids. The technology could be used for everything from desalinating water so its drinkable to storing renewable energy in massive batteries. (Think Californias water crisis or a municipal grid seeking cleaner power options).

Plaza, who founded Seattles Imperium Renewables, the first commercial biodiesel production facility in the western United States, immediately recognized the potential of the technology. He signed on as CEO of the company, Membrion Inc., in June 2017.

You can have a great solution to a problem, but if its more expensive than the existing solution, its an uphill battle, Plaza says. But if you have a great solution and its less expensive, you can get people to change their minds.

Investors are taking notice. Membrion, which employs 10 and operates in a 1,400-square-foot office in Pioneer Square, recently raised $2.23 million in an oversubscribed seed-funding round to commercialize the technology. The company also recently sold $1.485 million in securities to help fund operations through 2020, according to SEC filings.

Plaza says its too early to discuss profitability, but he expects early revenue later this year as it commercializes its first products. It plans to raise a series A round in 2020. Plaza says the global market for Membrions technology is $2.7 billion and growing.

We have competitors that sell a similar product, but its polymer-based, an extremely limited, 50-year-old technology with no area to improve, he notes. Nobody is approaching this from our perspective.
