Hi Ivan

I represent the portuguese association of start-ups. We would be a valuable partner to promote entrepreneurial initiatives on the results of the project, thus promoting the sustainability of the results

We also have something to say on renewable energy and batteries. For example one alternative to the not-very-green lithium battery could be the pumped storage hydropower

Another alternative is the heating of water, which is to use very very large and very well isolated water containers as storage of renewable energy. when you have an excess of energy you use it to heat up the water, and when you are lacking renewable energy you use the hot water to produce new energy

please write me to projects@apsu.pt if you want us in your project. we can also engage local municipalities

Kind regards

Nuno
