At the Danish Technological Institute (DTI) we strive to provide the industry with state of the art knowledge and test facilities to support the green transition through energy efficiency technologies, digitalization and partnerships. Our EnergyFlexLab is a unique digital platform that combines several of our highly specialised laboratories, enabling testing of subcomponents in a complex energy system. Our focus is to contribute to development and demonstrate technologies utilising as much renewable energy (RE) as possible through energy flexibility and sector integration. We believe that batteries will play a key role in the green transition of both the transport sector and the energy system. We therefore participate in Danish and European funded R&D projects that cover the full value chain around batteries. Such initiatives help us to further strengthen and apply our knowledge and test facilities so we are always suited to meet the needs of our collaborators.
