European colla­bo­ra­tions for innovation in sustainable energy

The European Institute of Innovation and Technology (EIT) is an EU body created by the European Union to strengthen Europe’s ability to innovate. EIT is active in different industries, such as manufacturing, health and culture. EIT InnoEnergy is responsible for accele­rating sustainable energy innovations and one of its tools for doing this is the European Battery Alliance for battery storage (EBA), that amongst other things produces training material for battery technology and electromobility. 

EIT InnoEnergy and EBA work with training providers all across Europe to adjust the training to local needs. Göteborgs Tekniska College are proud to be the first Swedish college to provide the online training from EIT InnoEnergy and EBA to the Swedish market.
