Wales and West Utilities (WWU) will develop an electrolyser designed to be capable of producing green hydrogen from highly contaminated industrial wastewater sources.
Alongside HydroStar and Cardiff University, the companies will use water high in microplastic and heavy metal pollution as a feedstock for the electrolyser, which would normally be unsuitable for the production process.
Combining pollutant removal with the low-carbon hydrogen production process is expected to reduce operational barriers, and enable the delivery of lower-cost green hydrogen to customers. The removal process also produces hydrogen and oxygen as byproducts, which can be captured as high-value goods to recover future energy costs.
