Sustainably Heating Heavy Industry

摘要

The high-grade heat required for heavy industry—such as for the production of cement, steel, petrochemicals, and glass—accounts for nearly 10% of global CO_2 emissions. The pathways to decarbonizing this sector are unclear. Fried-mann and colleagues have recently examined the state of low-carbon heating approaches for heavy industry. Existing options are costly, inadequate, or both. Increased efforts to decarbonize this sector through policy instruments and technology innovation are urgently needed.
