Industrial production of commodity chemicals traditionally relies on energy-intensive processes powered by fossil fuels, leading to significant greenhouse gas emissions. To address this challenge, electrified heating methods utilizing renewable electricity have emerged as a promising solution. Electrothermal approaches like Joule heating, induction heating, microwaves, and plasma have been investigated for synthesizing various chemicals, including hydrogen, with improved efficiency and sustainability. These methods offer new opportunities for achieving reaction outcomes unattainable with conventional reactors. Resistive heating, notably Joule heating, stands out for its flexibility in design and operation, making it a key player in advancing electrothermal synthesis. Choosing the right heater materials is essential for efficient resistive heating, considering factors like electrical and thermal properties, chemical stability, and dimensional accuracy. This shift towards electrified heating signifies a positive step towards decarbonizing the chemical industry and enhancing productivity while reducing environmental impact.
