What emits as much carbon as cars (6% of global emissions), planes (2%) and ships (2%) combined? The answer is industrial heating – kilns, reactors, chillers, crackers and furnaces, almost all powered by fossil fuels, emit 10% of our global CO2. And because of the high temperatures required (over 500 C / 932 F), likely substitutes – including biodiesel, renewable electricity, renewable natural gas, solar thermal, geothermal, thermal storage and hydrogen – are struggling to compete. According to the Center for Global Energy Policy at Columbia University, all these alternatives cost between two and 10 times more. Decarbonising is hard, but necessary.
