 The board instigated new more efficient and cost-effective processes for gas-making including a ‘Gas Integrale’ plant at Kensal Green in 1955, and a plant using low-grade coal at Bromley in 1960.The board also developed process for reforming oil to produce gas including plants at Southall and Romford and butane/air plants at Beckton, Bromley and Fulham.These new processes shifted the production of gas away from coal carbonisation to gas/oil reforming.
