Aquifer thermal energy storage for decarbonisation of heating and cooling: Overcoming technical, economic and societal barriers to UK deployment (ATESHAC)


Providing low carbon heating and cooling for buildings is a key challenge in moving to a net-zero economy.   Aquifer Thermal Energy Storage (ATES) is a type of geothermal seasonal energy storage that can deliver heating and cooling to large buildings, and heating/cooling networks, with very high energy efficiency and very low carbon emissions.  ATES recycles surplus heat and cool from buildings that would otherwise be wasted.

Typical ATES deployment using a well doublet. In summer (left), cool water is pumped out of the aquifer to provide space cooling, and warm water is pumped into the aquifer to store heat for use in winter. In winter (right), the system is reversed and operated with a heat pump: warm water is pumped out of the aquifer to provide space heating, and cool water is pumped into the aquifer to store cool for use in summer.

ATES is a key candidate technology for large-scale decarbonisation of heating and cooling in the UK, because the climate is seasonal and there are suitable aquifers beneath numerous large urban and industrial centres. However, uptake of ATES in the UK is low, with just a handful of projects in a few locations. In contrast, Holland has more than 2500 operational installations.

The broad aim of the ATESHAC project is to overcome technical, economic and societal barriers to large-scale deployment of ATES in the UK and other immature markets, by providing key data, knowledge and recommendations targeted at

  1. Industry, to raise awareness and reduce perceived technical and economic risks
  2. Government, to guide policy and stimulate uptake
  3. Regulatory authorities, to inform a fit-for-purpose regulatory framework

ATESHAC is a collaborative, multi-disciplinary project, involving researchers from the Department of Earth Science and Engineering, The Energy Futures Lab, and the Centre for Envionmental Policy at Imperial College London; the British Geological Survey, and the Department of Earth and Environmental Sciences at the University of Manchester.  

 

Project partners

ATESHAC is supported by eleven project partners who serve on the project Advisory Board, supply expert advice and guidance, provide key data, and provide a route to disseminate results direct to stakeholders.

  • The UK Department of Business, Energy and Industrial Strategy (BEIS) develops national and local policy pertaining to low carbon heating and cooling technology such as ATES
  • The UK Environment Agency develops and applies the regulatory framework for ATES
  • Mott MacDonald leads commerical development of ATES in the UK and internationally
  • IFTech leads commercial development of ATES in the UK and internationally
  • Storengy has broad interest in energy storage in the UK and internationally
  • HayesTec leads on district heating installations
  • National Grid ESO supports analysis of ATES in an energy network context
  • The UK Heat Pump Federation informs policy and works to raise awareness of heat pump technology
  • The UK Ground Source Heat Pump Association (GSHPAinforms policy and uses results to improve best practice and update relevant code(s)
  • THE UK Chartered Institute of Building Service Engineers (CIBSE) uses results to improve best practice and update relevant code(s)
  • The Geological Survey of Northern Ireland confirm UK-wide engagement and applicability

Funding

ATESHAC is funded by the UK Engineering and Physical Sciences Research Council (grant number EP/V041878/1).  ATESHAC was funded as one of eleven projects under a specific call for new technology solutions to decarbonize heating and cooling (see www.ukri.org/news/eleven-projects-launched-to-decarbonise-heating-and-cooling/).
