Green goals

ABB and Hydrogen Optimized Inc. (HOI), the Canadian technology innovator unlocking green hydrogen production at scale, have signed an agreement to expand the companies’ existing strategic relationship


This includes an investment by ABB into Key DH Technologies Inc. (KEY), the parent company of HOI, as it seeks to accelerate the fast-emerging green hydrogen production segment with unique large-scale architecture.

The signing follows the two companies’ showcase of their green hydrogen technologies at the German-Canadian Atlantic Renewable Hydrogen Expo in Stephenville, Newfoundland, which was attended by Canadian Prime Minister, Justin Trudeau and German Chancellor, Olaf Scholz. Hydrogen produced with low-to-zero carbon dioxide emissions is widely recognized as essential to achieving net-zero emissions by 2050.

By accelerating the strategic collaboration between ABB and HOI launched in 2020, the two companies are advancing the deployment of economic large-scale green hydrogen production systems to decarbonize hard-to-abate industries that address a wide range of essential needs.

The companies will leverage their respective capabilities and resources to rapidly commercialize HOI’s patented RuggedCell high-power water electrolysis technology for the world’s largest green hydrogen plants.

“This agreement positions us for success in the large-scale segment with customers requiring installations in the hundreds of megawatts to multi-gigawatts,” says Andrew T. B. Stuart, President and CEO of KEY and HOI. “ABB’s global footprint, commercial relationships and technology leadership in high-power rectifiers, distributed control systems and manufacturing automation provide us with the market reach and capabilities to achieve our company’s goals.”
