Cost effective green hydrogen.​

  • Efficient by design, with a new approach to hydrogen electrolysis.
  • No precious metals, no expensive deionized water feedstock.
  • Electrolysis from virtually any water source, including seawater, the world’s most plentiful water source. No desalination required.
  • By injection molding, our units can be produced in hours rather than months.
  • Recyclable parts, with longer duty cycles and far less maintenance.

“...This is genius.”

– Dr. Viola Birss, Electrochemist, University of Calgary

Our Story

Long Island Innovators Address Climate Change

Evolve™ technology was created in New York by two Long Island based innovators, Brian Gilman and Spencer Teplin.

Friends for decades, they sought solutions for the environmental needs of their families and the world. In their garages and workshops, they developed their electrolyzer by making it simpler and more durable than electrolyzers available at the time.

After studying traditional electrolyzers, finding them inefficient and expensive, they created a radical polymer-based redesign, eliminating precious metals. 

With climate change threatening fresh water supplies, they designed Evolve™ to use seawater, without the need for desalination.

Things really got interesting when they used seawater to replace the costly feedstock of deionized water, used by traditional electrolyzers.

Their first experiment with seawater showed promising results at an astonishingly low 7 degrees celsius.

Patents with 81 noble claims were soon awarded to Evolve™ in 9 countries.

Evolve™ R & D has been tested and verified internationally by several international labs and universities, including NREL, Calgary University, Strathclyde University, and AERTC at SUNY Stony Brook. 

Eliminating the standard costly and slow process of manufacturing by CNC milling, Evolve™ is a polymer solution that can be mass manufactured by injection molding, securing current and future jobs in the local manufacturing community. 

In 2022, Evolve Hydrogen Inc. won the 
US Department of Energy’s “H-Prize” Phase One, among only 9 other winners, and the only company in the northeast.

We want people to treat our electrolyzer like a toaster; a simple, durable, everyday appliance.
