DESCRIPTION:Aquifer Thermal Energy Storage (ATES) is an underground therma
 l energy storage technology that provides large capacity (of order MWth to
  10s MWth)\, low carbon heating and cooling to the built environment.  Hea
 ting and cooling currently produces 23% of the UK’s greenhouse gas emiss
 ions.  ATES can be a key technology for the UK to meet its net zero target
 s.  ATES offers a higher overall coefficient of performance compared to co
 nventional\, open-loop shallow geothermal systems: waste heat and cool is 
 captured and stored underground as warm and cool water\, so less electrica
 l energy is required by a heat pump to provide heating\, and cooling can b
 e delivered directly without the need for a heat pump. \n\n \n\nATES could
  make a significant contribution to decarbonising UK heating and cooling\,
  but uptake is currently very low with eleven systems meeting <0.01% of th
 e UK’s heating and <0.5% of cooling demand.  Despite the current low upt
 ake\, the UK has large potential for widespread deployment of ATES due to 
 its seasonal climate and the widespread availability of suitable aquifers 
 which are co-located with urban centres of high heating and cooling demand
 .  ATES could supply ca 61 % of UK heating demand and 79 % of cooling dema
 nd.  Widespread deployment in the UK offers a 16-41% reduction in carbon e
 missions for heating\, and 86-94% reduction for cooling\, compared to equi
 valent ground- or air-sourced heat pump systems. A key barrier to increasi
 ng uptake is lack of awareness of the technology.
