Low temperature (space heating, hot water services) heating accounts for 40% or more of fossil fuel consumption and we must look forward to a time when no fuel is burnt directly for heat but heat pump systems (whether electrically or heat driven) are used exclusively. To drive the emissions down to 20% or less of today's levels will need a diverse range of energy conversion devices including advanced thermal storage to manage peak loads, improved efficiency and user friendly heat pump systems, etc.

The projects proposed for initial investigation are:

• WP3.1 Compact chemical heat store
• WP3.2 Compact latent heat energy storage
• WP3.3 Advanced electric heat pumps
• WP3.4 Next generation gas/heat powered heat pumps
