As an alternative to most storage concepts, this technology consists of using a solid material, such as rocks, to increase storage capacity. Material costs will come down while storage capacity will go up. This will help improve heavy industry''s capacity to use waste heat from production. What is the value for society?
Waste Heat Recovery areas can be classified into four main groups : (i) energy recycling within the process, (ii) waste heat recovery (WHR) for other on-site processes, (iii) electricity generation with combined heat and power installations, and (iv) district heating systems. Each area of such WHR systems is accompanied by associated barriers.
Pumped thermal energy storage (PTES) is a promising long-duration energy storage technology. Nevertheless, PTES shows intermediate round-trip efficiency (RTE—0.5 ÷ 0.7) and significant CAPEX. sCO2 heat pumps and power cycles could reduce PTES CAPEX, particularly via reversible and flexible machines. Furthermore, the possibility to exploit freely …
