Modelling Scenarios for Low Carbon Heating Technologies in the Domestic Sector Towards a Circular Economy
The UK Government’s Net Zero strategy requires strong commitments to avoid catastrophic impacts of climate change. The built environment puts major pressure on the natural environment, especially with space heating-related emissions; therefore, transitioning to a circular economy is vital. In this direction, the heat pump market in the UK has been growing gradually whereas the number is still low (43,000 units in 2021). The UK Government aims to reach 600,000 heat pump installations per year by 2028, and according to the Climate Change Committee (CCC), this number should reach 1 million by 2030. In order to accelerate the transition, the Boiler Upgrade Scheme (BUS) has been introduced to provide a £5,000 grant in the UK, and the Scottish Government granted Home Energy Scotland (HES) loan and cashback scheme providing a £7,500 grant and a £2,500 interest-free loan for heat pumps. Islands are facing environmental, economic and social pressure due to the lack of connection to the mainland and dependency on fossil fuel imports. Exploring the benefits of renewable energy and low carbon heating technologies is crucial to overcome these issues. Orkney has a huge potential for renewable energy by producing electricity more than its needs. Therefore, this study chooses Orkney as a case study to explore potential heat pump uptake scenarios in line with government targets towards Circular Economy (CE). The study aims to create a comprehensive holistic approach to evaluate the environmental, energy and economic impacts of heat pump deployment scenarios. The consequences of replacing conventional heating technologies with heat pumps have been assessed through (i) comparative life cycle assessment (LCA) of heat pumps with gas boilers in UK houses, (ii) energy systems modelling (ESM) to optimise the performance of a heat pump coupled with thermal energy storage (TES) tank to reduce use phase related impacts in Orkney, (iii) building stock modelling (BSM) of Orkney’s domestic sector to understand the housing condition, (iv) ...
