The SCORES project aims to develop and demonstrate in the field a building energy system including new compact hybrid storage technologies, that optimizes supply, storage and demand of electricity and heat in residential buildings, increasing self-consumption of local renewable energy in residential buildings at the lowest cost. Combination and optimization of multi-energy generation, storage and consumption of local renewable energy (electricity and heat) brings new sources of flexibility to the grid and giving options for tradability and economic benefits, enabling reliable operation with a positive business case in Europe’s building stock. SCORES project optimizes self-consumption of renewable energy and defers investments in the energy grid. To properly evaluate the SCORES project solutions and their most promoting target countries, a market assessment is necessary. This report Market analysis on hybrid storage components aims to reveal the most important responses for the market assessment core questions.
