The overall objective of the Waste2GridS (W2G) project is to identify the most promising industrial pathways of waste gasification and solid-oxide cell (SOC) integrated power-balancing plants (W2G plants in short). The project aims are to perform a preliminary investigation on the long-term techno-economic feasibility of W2G plants to meet different grid-balancing needs and to identify several promising business cases with necessary preconditions. To achieve such goals, an interdisciplinary team is formed by gathering leading research bodies and companies in Europe in the fields of solid-oxide reversible cells (SORC), waste identification, gasification and syngas cleaning, grid operation, and energy/process systems engineering. The results of the project will further enhance the knowledge exchange and interaction among different key players (manufacturers, investors, and research institutions), provide useful guidelines for technology development/deployment and market positioning, increase long-term competitiveness and leadership of relevant industries, and provide knowledge for policy support on W2G plants for a circular economy and for the decarbonisation of European energy systems.
