Technical Components/ Infrastructure Selection

ROBINSON incorporates more low-carbon or renewable energy sources. In the notion of industrial symbiosis, for example, biomass and/or waste feedstock will be utilised. ROBINSON proposes many methods to meet environmental and economic goals, which will are discussed more in the relevant sections.

The case studies' future energy systems will incorporate renewable energy sources, namely wind and PV power, as well as sustainably produced heat sources such as biomass and (renewable) hydrogen. Furthermore, the newly proposed EMS attempts to always balance energy supply and demand while taking into account the restrictions of all system components. The ROBINSON EMS will guarantee the effective and intelligent integration of all distributed energy resources (DER), energy surpluses, and storage capabilities available on the island, while taking demand-side response, power balancing, weather forecasting, and market-related prices into account. Such an integrated system would offer a dependable, cost-effective, and resilient energy supply, so contributing to the decarbonization of European islands by phasing out fossil fuels and lowering CO2 emissions. The software's usability and adaptability will permit replication to additional energy islands with comparable conditions, which will be assisted by active participation of local communities and other stakeholders. The EMS will be developed with the local communities for the local communities with the aim to bring relevant business opportunities, while making sure that the fragile environment of the island is preserved.

It is worth noting that ROBINSON will be applied to an industrialized region of one of the three chosen islands, allowing for the installation of an industrial microgrid in conjunction with industrial symbiosis. As a result, the notion is also relevant to distributed (multi-)energy systems. Furthermore, Eigerøy and the Western Isles now have an energy grid link to the mainland, but Crete does not. The ROBINSON idea is to create an intelligent, resilient, and adaptable energy system (Figure 1) that integrates technology from several energy vectors (electricity, heat, and gas) and is underpinned by cutting-edge digital technologies like blockchain. 

To meet energy security limitations and reduce costs, the EMS will regulate the electrolyzer based on energy excess or energy storage needs, as well as the hydrogen storage level. If the stored hydrogen level has to be raised, the EMS will activate the electrolyzer. For the opposite case the device will be switched off.  Integration of innovative energy storage in the form of renewable gases will contribute to peak shaving and balancing of the local thermal, electrical, and gas networks, while individual source/sink elements and exchange between different local prosumers and the mainland will be required for a stable and efficient system. Other concepts, such as waste valorization and industrial symbiosis, will add considerable value to the system's cost-efficiency and environmental impact.
