A report funded through a Department of Energy grant examined a scenario that called for repurposing a Duke Energy coal plant into an energy storage system by integrating the retiring asset with a Malta long duration Pumped Heat Energy Storage system (PHES).
Finally, the existence of accsess in the form of former mining towns that have now been converted into population centres, and major road, rail and even air and sea connections, is another reason to argue in favour of the transition from abandoned sites to renewable power plants in pursuit of a net-zero economy and sustainable development. 2.2.
Finally, a CAES plant could be established, using the upper mine galleries for underground air storage; the fact that Lieres is a “dry mine” is ideal for this type of system. Thus, the abandoned mine facilities are efficiently used to generate both electrical and thermal renewable energy. Fig. 5.
Pumped storage power plants and compressed air energy storage plants have been in use for more than a hundred and forty years, respectively, to balance fluctuating electricity loads and to cover peak loads helping to meet the growing demand for sustainable energy, with high flexibility.
Conversion of old coal plant sites to new storage and renewable projects is happening in New Jersey, Nevada, Louisiana, and elsewhere across the country.
Turning abandoned mines into energy storage is one example of many solutions that exist around us, and we only need to change the way we deploy them,” concludes Behnam Zakeri, study coauthor and a researcher in the IIASA Energy, Climate, and Environment Program.
From capturing sunlight in vast expanses of open-pit mines, to optimising energy production through compressed air storage in underground mines, these innovations hold the key to unlocking a future where coal, far from being a liability, becomes a renewed resource for sustainability. 2.
