Summary

Industry accounts for almost a quarter of the energy use world-wide and energy-related carbon dioxide (CO2) emissions. Industry has several pathways to step-change GHG reductions including electrification of process heat, which is responsible for 50% of on-site energy use. Industrial heat pumps (IHPs) can beneficially electrify much of the process heat needed for low to moderate temperature applications, helping to make dramatic cuts in industrial GHG emissions. Our research shows that moderate IHP deployment in industrial groups with high process heating demands (e.g., pulp and paper, chemicals, and food manufacturing) can save up to 30% of the source energy or 221.6 petajoules/year (equivalent energy use/year of 1.5 million U.S. homes). In parallel, IHPs can reduce CO2 emissions up to 18.2 million metric tons /year (equivalent emissions from 4 million passenger cars or 1.3% of U.S. industrial CO2 emissions). Expanded adoption of IHPs across all industrial sectors would save even more energy and CO2 emissions.
