Abstract
SaFEGround – Sustainable, Flexible and Efficient Ground source energy systems – is an interdisciplinary research project focused on ground source energy systems (GSESs) and their potential contribution to the decarbonisation of heating and cooling. It covers several interlinked domains, spanning a range of scales. This paper summarises the key outcomes of the project and how they deliver new insights into the design and optimisation of GSESs. It is found that at the whole-energy system level, distributed domestic GSESs require substantial subsidies to be competitive with gas boilers and air-source heat pumps (ASHPs), and that gas boilers are preferred at low gas prices while GSESs require high proportional subsidies. Higher electricity grid upgrade costs favour GSESs. The true value of GSESs likely lies in (large) new-built properties as well as centralised heating systems, such as communal and district heating schemes.
