Rainer Gehrung of Home Power Solutions Discusses Cutting-Edge Hydrogen Storage Technology for Renewable Energy Independence

Rainer Gehrung, CFO and CSO of Home Power Solutions (HPS), delivered the third impulse lecture. With extensive experience in financial management and strategy development, Gehrung co-founded multiple companies including Steinbeis Hochschule Berlin and Smart Solutions for Industries. He introduced HPS as a pioneering German company enabling energy storage from photovoltaic (PV) systems for use across seasons. Gehrung emphasized the immense potential of solar energy, noting that while it’s abundant during summer months, it falls short in winter. To address this imbalance, HPS developed PKEA technology to store excess summer PV energy as hydrogen for winter use. This method offers substantial independence from utilities with a storage capacity up to 1,500 kilowatt hours—significantly higher than traditional batteries. The system is CO2-free and fully transparent since users rely solely on their generated energy without ambiguity about its source. Primarily catering to private households of varied demographics keen on modernizing or embracing new technologies, HPS aims to revolutionize home energy consumption through sustainable practices.

Photovoltaic prices have fallen continuously in recent years - a trend that should translate into a growing market for off-grid solutions. Declining costs are crucial for rural electrification in particular, making sustainable energy supply economically viable in remote regions. However, so far many of these price advantages have not yet reached the people that need them most. Do existing framework conditions to foster rural electrification still work in this new market reality? Which measures are needed to ensure that cost reductions reach our target group? This session discusses strategies for improving the availability of low-cost off-grid solutions, financing and innovative business models. A look at successful practical examples shows which political, economic and technological levers need to be pulled to make off-grid PV accessible on a large scale.
