How can we replace the fossil-fuel-derived heat that conventionally drives chemical processes with an emissions-free alternative? The current standard in industrial-scale heterogeneous catalytic processes, such as the production of ammonia and hydrogen, is to use heat supplied by the combustion of natural gas. Heat can alternatively be supplied from non-fossil sources, such as renewable electricity; however, assessing the net impact on carbon emissions of electricity-based processes remains non-trivial.
