The unit at Hanson UK's site generates hydrogen using electrolysis, which splits water into oxygen and hydrogen. While it may have a lower carbon footprint than Portland cement, Regen GGBS remains an energy intensive product, requiring substantial amounts of electricity and natural gas.Īccording to Swansea University, the idea behind the Port Talbot project is to 'replace some of the natural gas used at the plant with green hydrogen, which is considered a clean source of energy as it only emits water when burned.' This, the policy institute said, amounted to roughly 8% of global CO2 emissions. think tank Chatham House, over 4 billion metric tons of cement are produced annually.
The effect of cement production on the environment is considerable. The term GGBS refers to ground granulated blast furnace slag, which can be used instead of cement when producing concrete. In a statement last week, Swansea University said the green hydrogen unit - which is housed inside a converted shipping container - had been installed at Hanson UK's Regen GGBS plant in the town of Port Talbot, south Wales.
