Energy sustainability of new service buildings should considers the use of envelope materials able to minimize thermal dispersions avoiding at the same time environmental and landscaping impacts specially in the small islands of Mediterranean sea generally characterized by high environmental and landscaping values. In this context, the paper provides an analysis of local materials for the design of low-energy service buildings in touristic islands, according with the concept of re-use. As a preliminary result, a case study in Favignana Islands is presented designing a modular and temporary structure using local materials and municipal solid waste. The pilot project includes a summer and a winter design, and can be replicated in similar contexts.

Among the several typologies of storage technologies, mainly on different physical principles (mechanical, electrical and chemical), hydrogen produced by power to gas (P2G) from renewable energy sources complies with chemical storage principle and is based on the conversion of electrical energy into chemical energy by means of the electrolysis of water which does not produce any toxic or climate-relevant emission. This paper aims to pinpoint the potential uses of renewable hydrogen storage systems in Europe, analysing current and potential locations, regulatory framework, governments’ outlooks, economic issues, and available renewable energy amounts. The expert opinion survey, already used in many research articles on different topics including energy, has been selected as an effective method to produce realistic results. The obtained results highlight strategies and actions to optimize the storage of hydrogen produced by renewables to face varying electricity demand and generation-driven fluctuations reducing the negative effects of the increasing share of renewables in the energy mix of European Countries.
