Heating and cooling both make up a large part of the total energy demand in UK; long-term seasonal thermal storage (STES) can address temporal imbalances between varying supply heat to buildings processes. Underground (UTES) play role decarbonisation by storing waste from space cooling, refrigeration, data processing, industrial processes, harvested summer solar or even generated surplus renewable (solar wind) electricity with fluctuating supply. This paper evaluates range UTES technologies UK context addresses geological suitability, capacity, low-carbon sources, surface sources demand. review concludes that there is significant potential for aquifer (ATES) borehole (BTES) systems, coinciding Therefore, uptake technology will help achieve net-zero carbon neutral targets 2050. There also scope utilise within existing subsurface infrastructure. are 464 oil gas wells which could be repurposed upon end life using different technologies. However, repurposing needs further evaluation; deep single well BTES systems have high area volume ratio storage, reducing efficiency such ATES limited issues associated contaminants. 23,000 abandoned mines underlay ∼25 % UKs population utilised minewater (MTES).

Repurposing a deep geothermal exploration well for borehole thermal energy storage: Implications from statistical modelling and sensitivity analysis

Applied Thermal Engineering, Journal Year: 2022, Volume and Issue: 220, P. 119701 - 119701

Borehole thermal energy storage (BTES) is an important technology to minimise greenhouse gas emissions by storing surplus heat from industrial processes, space cooling or even excess summertime renewable wind solar energy. This paper investigates the efficiency of BTES via a single deep ex-geothermal exploration well in Newcastle, retrofitted using coaxial borehole exchanger (DBHE) completion. Previously, few studies have investigated 1) use DBHE for 2) retrofitting well; therefore, this study through numerical modelling on MATLAB testing impacts 10 design parameters operational performance both global and local sensitivity analyses. Under base-case conditions, operating at depth 920 m could achieve extraction rate c.54 kW recorded end 6 month (winter) production phase. When applying (summer) charge phase prior (recorded as 250 period), yield was increased minimum c.69 kW. In total, over annual cycle, 1.23 GWh injected into formation, 0.46 extracted. Across all simulations, average 9.5–55.6 following period charge. The analysis demonstrated that recovery most influenced such undisturbed geothermal gradient, flow rate, inlet temperature during extraction. Most these are parameters, indicating systems can be optimised careful engineering. concludes DBHEs some capacity store heat. However, additional only modest proportion reinjected formation charging (calculated <20 % new metric proposed study). approach likely viable where there large source with little alternative value, existing suitable retrofitting. If conditions do not exists, more conventional, shallower, multi-borehole arrays BTES.

Integration of curtailed wind into flexible electrified heating networks with demand-side response and thermal storage: Practicalities and need for market mechanisms

Increasingly high renewable penetration in electrified energy systems causes increasing levels of curtailment that must eventually be mitigated. System flexibility, storage and demand-side response the form flexible heating cooling demands are efficient solutions for mitigation, however challenges remain such as economic benefits financial impacts mitigation on consumers, among others. In this paper curtailed wind energy, incentivised with discount payments, through networks thermal is investigated a genetic optimisation algorithm, results analysed terms overall costs, technical feasibility level use from perspective network operator consumer. It found large-scale lowers cost increases integration, allows district to run almost entirely otherwise (up 97.0 % example considered here). However without adequate market mechanisms, financially beneficial all stakeholders only at low levels; split approach, incentives or mechanisms necessary higher of, more efficient, mitigation.
