Electromagnetic induction heating is being studied as a way to decarbonize energy-intensive chemical reactions that currently rely on fossil fuel combustion. A review from Beijing University of Chemical Technology covers three types of susceptors: carbon-based materials, macroscopic metals, and magnetic nanoparticles. Each heats differently and suits different reactions, from CO2 conversion to methane coupling and ammonia decomposition. The technology offers fast start-stop response on a second timescale and precise temperature control, which makes it a possible fit for intermittent renewable electricity. Reported lab results include high CO2 conversion and high yields in several endothermic reactions. The main open questions are long-term susceptor durability, scale-up beyond lab reactors, and a full techno-economic assessment comparing induction heating to conventional furnaces in real industrial settings.
