There is significant and growing momentum for the decarbonization of heating, driven first by the parallel and related momentum to replace fossil fuel-based power generation with renewables and the corresponding end use as well as primary energy efficiency increase of a Heat Pump over the furnaces and boilers they replace. But, the corresponding driver trend to increased percent of power generation coming from renewables also creates a supply/demand disconnect which has to be addressed by various forms and durations of supply and demand-side storage. 

Additionally, there is a significant variation in the efficiency and resulting heating costs / decarbonization potential of the Heat Pumps implemented, depending on the differential temperatures they have to achieve, and relat ...
