The BERLIN project was presented at the SyNERGY MED 2022 Conference by Dr Alexandros Arsalis, Special Scientist at the FOSS Research Centre for Sustainable Energy of the University of Cyprus. The presentation described how the BERLIN project can set the foundations for future advanced energy systems that can help achieve decarbonization targets by exploring energy storage technologies that can include storage beyond batteries. This could include the additional integration of a Photovoltaic battery microgrid system with a regenerative hydrogen fuel cell subsystem. Such a subsystem includes electrolyzer, fuel cell, and hydrogen storage units; it can provide long term energy storage, with a reduction of the capacity of the battery units in the overall system. Such a configuration may also provide green hydrogen for the fuelling of hydrogen electric vehicles. In this study a preliminary investigation of integrating a green hydrogen subsystem to a predefined PV-battery nanogrid is conducted.

The 2^nd International Conference on Energy Transition in the Mediterranean Area continues the idea of establishing a major energy platform in the region. The conference focused on topics of interest to the Energy Challenges in the Mediterranean area. The conference aimed to address the vast technological changes in all areas of the electric energy business, products, equipment, methods, etc. SyNERGY MED 2022 provided a forum for discussion among researchers, policy-makers, regional and local authorities, renewable energy clusters and main actors/stakeholders about the energy technology challenges in these regions and solutions for boosting economic and sustainable development. The paper was presented during the technical session of ‘Renewables’.
