    Energy communities can be an effective means of re-structuring our energy systems, by empowering citizens to drive the energy transition locally and directly benefit from better energy efficiency, lower bills, reduced energy poverty and more local green job opportunities. Renewable energy communities, as defined in Article 2(16) of Recast Renewable Energy Directive (Directive (EU) 2018/2001) can introduce positive environmental impacts by increasing the use of renewable energy, thereby enhancing local energy security and reducing energy import from the main power grid, lowering energy bills. This aggregation therefore increases collective advantages and furthermore benefits the local distribution grid thanks to sharing resources and to a more efficient energy distribution, respectively. Energy communities are also key in bearing the adoption of new energy technologies and practices, thus paving the way toward innovation in the energy landscape.
    In the context of the scope of renewable energy communities, proposals are expected to demonstrate an integrated renewable energy system applying stationary fuel cells, possibly in combination with other hydrogen technologies, to supply reliable and efficient energy in at least one renewable energy community.
