Developing the world's first high pressure, ultra-efficient electrolyser MoreLess

Supercritical is a UK-based clean-tech startup that operates in the sustainable energy industry. The company's primary focus is on the development and implementation of innovative clean technology solutions that aim to replace fossil fuels. Supercritical's main product is a high-pressure, ultra-efficient electrolyser that produces hydrogen with zero emissions. This electrolyser is unique in that it operates at 99% Higher Heating Value (HHV) efficiency, which means it uses almost all the energy it consumes to produce hydrogen, making it highly cost-effective.

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.
