LC-H2 Low-cost H2 production by high-performing alkaline water electrolysis
| Hydrogen is envisioned to become a key enabler and energy carrier in the future 100% renewable energy system with predicted applications within transportation, grid stability, industry, re-electrification, etc. The current Low-Cost Hydrogen project (LC-H2) has a game changing, break-through potential in the field of green hydrogen accelerating the entire PtX market. The project aims to validate/demonstrate electrolyser current density of 400 mA/cm2@1.6V and improve the efficiency of Alkaline Water Electrolyser (AWE) cell from today state-of-the-art of 63% energy conversion efficiency to 77% by combining different electrode/bipolar plate inventions in an optimised MW electrolyser configuration. The new inventions will make it possible to double the current density from 200mA/cm2 to 400mA/cm2 for the stack and thereby reduce the electrolyser stack CAPEX by a factor of two. Modelling technique and neutron imaging will be used for eliminating inflow/outflow bottlenecks in the cell supporting further optimisation of the cell efficiency – especially at high current densities. In short, the LC-H2 project will make improvements to the key components of the alkaline electrolysed stack for green hydrogen to be able to compete with hydrogen from fossil sources and thereby pave the way for a society based on 100% renewable energy. |
