Read full description
The company serves all major hydrogen markets, offering them a chance to reduce their capital expenditure (CAPEX) and system complexity while increasing reliability. Supercritical's electrolyser is also environmentally friendly, as it does not use scarce critical materials like Iridium, PFAS chemicals (also known as forever chemicals), and rare earth metals in its production process.
Supercritical's business model revolves around partnering with industries to implement their technology. They make money by selling their high-pressure electrolysers and providing clean technology solutions. The company's approach is game-changing, as it offers a solution to the high cost of renewable energy, which is the biggest contributor to the cost of green hydrogen.
In conclusion, Supercritical is a pioneering clean-tech startup that is making significant strides in the sustainable energy industry with its innovative, efficient, and environmentally friendly hydrogen production technology.
