Power-to-Heat Technologies for Renewable Heating of Gas-Solid Reactors beyond 500°C

Kurzfassung

Electrification of chemical processes using renewable electricity has emerged as a promising transition path to low-carbon manufacturing of chemicals. Particularly, substituting high-temperature heat above 500°C with renewable electricity offers high potential to mitigate harmful process emissions. However, available industrial-scale power-to-heat technologies are limited to temperatures of 700 °C. This contribution provides an overview of emerging power-to-heat technologies, that are pushing the boundaries of the state-of-the-art for heating chemical reactors, targeting an efficient heat supply at temperatures far beyond 500 °C. The presentation also reports on current work on high-temperature heating with a novel ceramic-based induction heater. Current concepts are outlined and experimental results from the operation of a 100 kW prototype are presented.
