It was observed that grid-connected vapor-compression heat pumps/chillers (conventional systems) presented higher GWP impacts than other AC systems powered by renewables, which in contrast, exhibited higher impacts in some toxicity and resource depletion-related indicators. However, the share of GWP ...

Geothermal power plants (large-scale) and geothermal heat pumps (GHPs) (small-scale) convert heat from the Earth’s interior into electricity using steam or hydrocarbon. Geothermal energy was once location dependent—requiring access to geothermal reservoirs deep under the Earth’s crust. The latest...

Lars Ivar Nitter Havro, a senior analyst at Rystad Energy—who expects to see a global sevenfold increase in demand for heat pumps by 2050—said chip supply chains were still “feeling some of the aftermath” of COVID lockdowns. But he also warned of possible future problems, owing to de...
Energy consumption (heat, electricity and fuel) of each individual process unit is measured. As both production and energy consumption data are available, it is possible to generate SEC figures on process level. The total amount of gas and electricity use is reported as well as the efficiencies...
The solar-assisted heat pump technology (SAHP) has been introduced and researched, and is considered to be one of the most promising clean heating technologies in the near future (Song et al., 2021a). Long et al. (2019) proposed a SAHP system with a dual heat source integrated heat pump...
