The article discusses the benefits of hydrogen-based microgrids for establishing decentralized power networks with renewable energies. These microgrids store electricity generated from solar and wind power in the form of hydrogen through electrolysis, allowing for extended periods of energy storage. This technology is crucial in preventing overloads in the power grid and bridging periods of low energy production when there is no wind or sunshine, known as 'dark doldrums.' The stored hydrogen is converted back into electricity using fuel cells in the grid, making these microgrids ideal for local energy networks and offshore containers. Compared to battery storage, hydrogen storage offers advantages such as the ability to store large amounts of energy for extended periods with low self-discharge rates, making it suitable for seasonal energy storage. The Reference Factory.H2 from Fraunhofer IWU has developed concepts for applications in sports centers and hospitals in Germany, where the oxygen produced during electrolysis can be utilized for various purposes. The article also highlights the showcasing of the H2 microgrid platform HyGrid at Hannover Messe, featuring the innovative HyVentus electrolyzer. Strategic partnerships with companies like Siemens AG aim to drive the development of robust, cost-effective microgrid solutions with reduced manufacturing costs, catering to various application scenarios. The Fraunhofer Society is promoting the HyGrid as a cost-effective plug-and-play microgrid solution that can range from a few to several hundred kilowatts, catering to different sectors and regions. The article also mentions the experience of the Reference Factory.H2 with H2 microgrids, including the HyTrA project in Cape Town, South Africa, providing insights into the operation and maintenance of such solutions.
