LWS potential in relation to repurposing of coal power plants is due to their infrastructure distinguishing characteristics. Existing grid connection point and active high rise construction permits enable to reduce LWS CAPEX. Moreover, ash and slag left over due to coal combustion can be used to produce weights and reinforced concrete structures.
According to the calculations of Energozapas’ experts, existing infrastructure of coal power facilities enables to reduce LWS construction capital costs by about 20%. The storage lifetime is 50 years, full cycle efficiency is 83%, and about 75% of the capital costs can be localized in the region where LWS is built.
LWS is an eco-friendly energy storage technology that is aligned with the initiative of European countries to reduce carbon emissions. The problem of slag and ash (left overs due to fossil fuel combustion on the territory of coal power plants) recycling is under consideration of the same initiative.
Summing up, the RECPP workshop participants came to the conclusion that emission reduction program could not be implemented without energy storage technologies. These technologies are becoming more and more requested every year, and their development will inevitably cause creation of regulatory framework, that will cover long-term energy storages as well.
Repurposing of coal power plants in Europe as part of the energy transition (RECPP project) opens up development opportunities for regions with these conventional generation facilities. Re-purposing of assets contributes to elimination of fossil fuel, to economical, social and green development of coal regions with transition economy. It provides European and local communities with options to re-use territories and to incite development, supports industry innovations and encourages investments in green technologies.
