| Abstract |
In 2013 a “renewable heat incentive” (RHI) was introduced in the UK to accelerate the adoption of renewable heat technologies in order to meet the EU 20/20/20 RES Directive. The incentive scheme had to encompass multiple heat technologies at domestic and non-domestic scale, set appropriate tariffs, and establish heat metering requirements and tariff control mechanisms. At the time of introduction, heat pumps, including GSHPs, were expected to develop as significant, long-term contributors to the decarbonisation of heat in the UK. This paper describes the evolution of the RHI, specific issues related to GSHP systems, and the ensuing impact that it has had on the UK GSHP industry. |
