Off-Grid: PV-Based Hydrogen Microgrid Projects Around the World

Philipp is an international expert in island energy supply and rural electrification. He conducted a PhD in engineering about 'Barriers to implementing renewable energies on Caribbean islands' at the TU Berlin. In 2011, he joined the Reiner Lemoine Institut and he started to develop the Off-Grid Systems Research Unit, which he is currently heading. Within the Unit, he develops and manages projects and strategic processes. In 2019 Philipp was appointed Visiting Scholar in the Renewable and Appropriate Energy Laboratory (RAEL) of the University of California, Berkeley as part of the C-BEAR+ project and he is a selected member of the Arab-German Young Academy of Sciences and Humanities (AGYA) at the Berlin Brandenburg Academy of Sciences and Humanities. Since 2020 he is also leading the RLS-Graduate School on Energy System Transition with currently 6 PhD students.

Jonas Pluschke holds a PhD in Environmental Process Engineering from TU Berlin, where he focused on industrial water management and sustainable resource solutions in several international projects. He now works on the integration of hydrogen technologies into renewable energy systems, particularly photovoltaic-battery-hydrogen microgrids for resilient off-grid power supply. Within the GH2GH project, he is involved in developing and operating a PV-hydrogen microgrid in Ghana that combines renewable electricity generation with hydrogen production and storage. His interests include system integration and the practical deployment of sustainable infrastructure in emerging markets.

With over 25 years of experience, Manfred Limbrunner is a leading figure in the fuel cell industry. During his 24-year tenure at Proton Motor, he served in key roles ranging from CTO to Board Member; as Director of Sales and Marketing, he was instrumental in developing the company's brand and driving its commercialization.Today, at H2 Powercell GmbH, he leads the marketing and sales of electrolysis and hydrogen technologies. In this role, he also supports partner companies BEN-Tec and Hydro Generation in implementing decentralized, renewable energy solutions for efficient, carbon-neutral power and heat generation.

Michele Velenderic is an engineer, IT consultant, and software developer. As the Founder and CEO of the Munich-based company Green Power Brains, his expertise spans the planning and installation of off-grid power systems and microgrids, decentralized green hydrogen, energy management systems, and e-mobility, alongside a deep commitment to education in the renewable sector. Driven by his passion for all forms of green and renewable energy, he brings his technical and entrepreneurial expertise to his role as Co-CEO of subasol AG, a Swiss joint venture dedicated to innovative solar and energy storage.
