Green hydrogen as an energy carrier sits at the heart of the global energy transition today.
Not every company that has moved on the opportunity in the past five years has delivered on their ambitions, but one tangible success is Stargate Hydrogen in Estonia, which since 2021 has been busy developing a novel alkaline electrolyser.
The step-change the Stargate Hydrogen electrolyser stack delivers lies in the catalysts the technology deploys. It uses ceramic-based materials rather than scarce and costly precious metals, such as iridium or ruthenium, which other electrolysers need.
It’s an innovation that has several clear benefits, including lower material costs and energy consumption, thereby making green hydrogen that much more viable as it scales. It also extends the lifespan of the equipment in use, cutting maintenance and downtime to improve the economics.
