Industrial sites have considerable potential to utilise low-temperature excess heat from cooling for heating via pumps, limited mainly by the overlap of and demand profiles. Coupling industrial infrastructure with district (DH) systems is therefore an attractive solution, as DH requires new sources decarbonisation.This article examines techno-economic feasibility converting a substation at German production site into prosumer using TRNSYS simulation model incorporating pump, cold storage, allowing bi-directional transfer substation. Subsequent optimisation minimised levelised cost (LCOHC) adjusting pump capacity.The results indicate that integration without feed-in, reduces LCOHC about 10% compared decoupled cooling. However, achieve similar in configuration, which includes feeding surplus network, compensation payment 80% current costs required. This arrangement allows increase capacity 27% output, providing 4~GWh/a system May September.

The European Union has established ambitious targets for lowering carbon dioxide emissions in the residential sector, aiming all new buildings to be “zero-emission” by 2030. Integrating solar generators with hydrogen storage systems is emerging as a viable solution achieving these goals homes. This paper introduces linear programming optimization algorithm aimed at improving installation capacity of solar–hydrogen systems, which also utilize waste heat recovery from electrolyzers and fuel cells increase overall efficiency system. Analyzing six cities diverse climate conditions, our techno-economic assessments show that optimized configurations can lead significant net present cost savings electricity over 20-year period, potential up EUR 63,000, amounts 26% reduction, especially Southern Europe due its abundant resources. Furthermore, enhance sustainability viability sector significantly reducing emissions. Our study does not account economic benefits EU subsidies. Instead, we propose novel incentive policy allows owners inject 20% their total power output directly into grid, bypassing storage. strategy provides two key advantages: first, it enables profit selling excess photovoltaic during peak midday hours, rather than curtailing production; second, facilitates reduction size—and therefore cost—of electrolyzer.
