My project will have a biofuel generator. Does that qualify?

Can I sell the RECs my system generates to help pay for the upfront costs?

Hello, We have a project located in Sweden. Does an akvifer that stores heating and cooling count as renewable energy? The akvifer has two sides - a cold and a warm. Exessive heat from the buildings equipment is thrown down in the akvifer ("loading" it and storing for the winter). Outside air cools the cold side of the akvifer ("loading" it and storing for the summer).

The source for making the heating and cooling must be renewable. Sounds more like heat recovery on the heating side. On the cooling side is sounds sort of renewable but I assume that there is some sort of equipment that transfers the cool to the aquifer from the outside air. So in both cases you are probably using grid electricity to move the heating and cooling. In this way it is similar to groundsource heat pumps which are not considered renewable.
