D1.6 Report on the assessment of the environmental sustainability (V1)

The present deliverable focuses on the environmental evaluation using Life Cycle Assessment (LCA) methodology of the RESTORE prototype, which combines the Organic Rankine cycle / Heat pump and Thermochemical Energy Storage technology. The following processes are taken into account when conducting the LCA study: i) upstream processes: raw material supply chains (e.g., Novec 649 supply chain, copper sulphate supply chain, oil procurement and production, RESTORE prototype construction) ii) thermal energy charging and discharging cycles; and iii) downstream processes: recycling of Novec 649, copper sulphate, and oil; wastewater treatment and purification. Traditional Life Cycle Assessment (LCA) methodology has been employed to thoroughly address each of the four stages of LCA: 1) defining the objective, parameters, and limits of the system 2) assessing the input-output inventory 3) evaluating the impact on the environment 4) analysing the results while offering recommendations for improved performance.
