Process Heat

What is process heat?

Process heat is the use of energy in the form of steam, hot water or hot gases in industrial processing and manufacturing. The main fuel source of process heat at the moment is from burning of coal and other fossil fuel.

New Zealand has a long-term greenhouse emissions reduction target to reduce greenhouse gas emissions to 50 percent below the level of 1990 levels by 2050. Electrification of process heat can pay a big role in this when electricity that is used is generated from renewable sources such as solar, wind and hydro.

The Energy Efficiency & Conservation Authority (EECA) and the Ministry of Business, Innovation and Employment (MBIE) are working on a Process Heat in New Zealand (PHiNZ) initiative which looks at the opportunities to improving energy efficiencies of process heat.

More information on process heat can be found on both the EECA and MBIE websites.

EECA also helps administer the GIDI Fund (Government Investment in Decarbonising Industry) which supports decarbonisation of industrial process heat.
