Data-driven energy research produces large amounts of data. However, the majority of databases don’t allow for re-analysis and lack integration of interdisciplinary and complex data. Tapping the enormous potential of energy data is crucial for informed decision-making, accelerating the market uptake of research results, and thereby guiding the successful transition to a clean energy system. Together, the project partners from Norway, Turkey, Austria, Italy, Belgium, and Poland strive to advance efforts on opening databases and making low carbon energy data findable, accessible, interoperable, and re-usable – FAIR.
