Part of London Climate Action Week 2020 #LCAW2020


Decarbonising heat is one of London’s biggest challenges to achieving net zero emissions. Natural gas, used mainly for heating buildings and water, accounts for 37 per cent of all greenhouse gas emissions in the city and London will therefore need to make a rapid transition from gas to low carbon heating solutions, the majority of which will be retrofitted into existing buildings, since at least 80 per cent of our buildings are expected to still be standing in 2050.

Heat Pumps are seen as playing a key technology in helping this transition to zero carbon heating, but progress in roll out both in the capital and more widely has been limited. The Renewable Heat Incentive (RHI), the government’s flagship mechanism for supporting heat pumps, has supported a mere 66 installations per year on average since 2014.

Building on a major new report issued by the Greater London Authority (GLA) – Heat pump retrofit in London – this event will discuss the challenges and opportunities to introducing heat pumps into London’s homes and offices and also how community-led projects could come forward.

Sarah Fletcher – Principal Policy & Programme Officer – New Energy Efficiency Programmes, Greater London Authority @LDN_environment – her presentation can be viewed here.

Toby Costin – Chair of CREW Energy. Toby will be looking at how community energy groups can get involved in heat project across the capital @CREWEnergyLDN – his presentation can be viewed here.

Magnus Henderson is Development Manager at Black Mountain Developments, a company which creates dedicated solar generation and implements very low carbon heating and cooling systems using heat pumps and geo-exchange technology. – his presentation can be viewed here.

Magnus will describe the levels of energy saving and carbon reduction which can be achieved by using the earth as both a source of renewable energy and as battery for storing captured waste heat. He will talk also about an innovative approach to building closed-loop, ground-coupled heat pump systems in areas, like many parts of London, where space is limited.

Heat pumps are a highly efficient form of electric heating. Due to their high efficiency and the ongoing rapid decarbonisation of grid electricity, heat pumps have the potential to deliver CO2 savings of 60-70% compared to conventional electric heating and 55-65% compared to an A-rated gas boiler. These savings increase when combined with energy efficiency measures to reduce space heating demand. As the grid decarbonises further in coming decades, the carbon savings delivered by heat pumps are expected to increase further towards 90-100% CO2 emissions reduction by 2050.
