About Aqsorption

Aqsorption Ltd is a Nottingham-based engineering and research company founded in 2017, operating as the dedicated research arm of the AqGas Group. The firm specializes in developing bespoke engineering solutions for the zero-carbon hydrogen production and fusion energy sectors. A core focus is its patented, membrane-free electrolysis technology. This 'flow-through' design uses porous electrodes to inherently separate hydrogen and oxygen gases, which eliminates the need for a traditional membrane. The benefits of this approach include enhanced robustness, the ability to handle intermittent power from renewable sources, and suitability for high-pressure operation, potentially removing the need for downstream gas compression.

The company's technology is designed to be more efficient and operate at higher pressures than conventional systems, with the goal of reducing maintenance costs and reliance on expensive rare earth minerals. Aqsorption is also developing systems to recover kinetic energy from the high-pressure oxygen output to further boost efficiency. Beyond hydrogen production, the firm applies its electrolysis and isotopic separation techniques to the fusion energy sector. This includes developing systems for handling tritiated water and separating hydrogen isotopes like deuterium and tritium, using innovations like 2D graphene-based isotopic sieves. The company has engaged in research collaborations with the University of Nottingham and the Graphene Engineering and Innovation Centre at the University of Manchester. It has received funding from entities such as the Net Zero Technology Centre and the UK Atomic Energy Authority's Fusion Industry Programme to accelerate technology development.
