As housing developers grapple with the implications of a changing landscape with legislative changes driving the delivery of more sustainable homes, brick manufacturer Michelmersh is piloting an innovative global project to assess a new brick manufacturing process using green hydrogen. Michelmersh’s innovation director, Sarah Le Gresley, explains more about the potential that lies behind the trial to produce the world’s first 100% hydrogen-fired clay brick. The nation’s housing stock is viewed by policymakers as a key component of the long-term aim to deliver a low-carbon future. COP26 outlined the perils of the impending climate crisis and government moves such as the changes implemented to Part L of the Building Regulations are designed to ensure we start building more energy-efficient, low-carbon, sustainable homes.
