World’s smallest pressure regulator for hydrogen gas unveiled in Warsaw

water stuff & sun GmbH, a hydrogen startup, has unveiled its latest technological innovation - the world's smallest pressure regulator for hydrogen gas, in Warsaw. This new technology combines safe and easy storage with the direct use of green energy, a first in the industry.

The microvalve system is a core component of the miniature pressure regulator, measuring only a few micrometres in size, and is part of a silicon chip that measures 4x4x2 mm. The regulator is capable of controlling hydrogen release in steps from 1000 bars down to just a few bars.

The lightweight and flexible SFEERS carbon fibre high-pressure storage cells will integrate the miniature pressure regulator, allowing for a highly modular system that can be customized to power hydrogen fuel cells or hydrogen combustion engines of all sizes.

According to Thomas Korn, CEO and co-founder of water stuff & sun GmbH, "A successful energy transition requires a shift from fossil fuels to renewable energies, and hydrogen as an energy carrier will be able to make a decisive contribution to this. With our technology, we are making green hydrogen safe, cost-efficient and easily available and thus competitive with fossil fuels. With the successful development of the pressure regulator prototype, we have achieved a decisive technical breakthrough that represents an important milestone in the overall development of the hydrogen battery."

The worldwide patented technology will debut at the Energy Tech Summit in Warsaw (26 and 27th April), which brings together investors, entrepreneurs, and government representatives from over 40 countries to showcase the latest developments in energy and mobility. The development move comes at a good time, as the startup opens its next investment round.
