The ULLEVI project (Eng. New business from thermal energy storage) addresses the future challenges faced in matching the energy production and demand by producing new information, solutions, business potentials and innovations about thermal energy storage by developing an environment for demonstration, piloting, research, education, application and joint use. The project will deepen the knowledge and competence in the field by improving the efficiency and credibility of carbon-neutral solutions, energy systems integration, as well as networking between the partners and stakeholders. ULLEVI project will support the sustainable growth, internationalization, and renewal of SMEs. The project will promote the climate change mitigation efforts and the development of self-sufficient, secure and resilient business life in South-West Finland. Simultaneously it will reduce EU’s dependence on imported energy sources. ULLEVI supports the government’s “Carbon neutral Finland 2035” strategy, particularly with respect to developments in the heating market, waste heat utilization (e.g., in district heating networks), R&D, innovations and competition as well as in securing the maintenance and supply. The developed knowledge and solutions on long-term thermal storage support Finland’s goal of carbon neutrality with respect to the transition to an electrification of the heating sector, including education of the future experts.
