Water Stuff & Sun

water stuff & sun is a German start-up specializing in the development of innovative storage and infrastructure technologies for renewable energies. Founded in December 2016 near Munich, the company works closely with internationally renowned European research institutions and industry partners.

The core of the technology from water stuff & sun is the so-called hydrogen battery, a 2-in-1 storage and application solution. This battery consists of so-called SFEERS (Small, Flexible, Efficient Energy Reservoirs), which function as tennis ball-sized, spherical high-pressure containers made of carbon fiber. Each SFEER contains a micro-valve system made of silicon that regulates the hydrogen flow, similar to a conventional valve, but at significantly lower weight and cost[3][5].

This innovative technology combines the safe and easy distribution of renewable energies with their integration into various applications, both mobile and stationary. Compared to lithium-ion batteries, the hydrogen battery is about 95% lighter and up to 30 times more cost-effective, with the same energy content[2].

The mission of water stuff & sun is to make the storage and use of renewable energy simple, safe, and cost-efficient. The company aims to make green hydrogen competitive with fossil fuels. The vision is to develop the world's leading standard for green hydrogen solutions, thus enabling an emission-free energy future[2].

water stuff & sun is firmly committed to shaping an emission-free energy future. The hydrogen battery eliminates the need for multiple compression or conversion steps and various storage media used between energy generation and usage. This reduces infrastructure costs and allows for rapid scaling of the system. As a result, green hydrogen can be provided for applications such as trucks, drones, airplanes, and other areas at significantly lower costs[4].

The company has already achieved significant milestones, including the successful validation of the micro-valve system and planning for the completion of a complete hydrogen battery system in the second half of 2024. water stuff & sun continues to seek strategic partners and investors to advance this visionary technology[4].

The leadership team of water stuff & sun consists of experienced experts in hydrogen technology. Thomas Korn, the CEO, has over 25 years of experience in developing hydrogen technologies, including his work at BMW and the start-up KEYOU. Jonas Flädjemark, the COO, and Alvaro Sousa, the CSO, also bring extensive experience from the automotive and hydrogen industries. Erwin Deutscher, the CTO, has more than 25 years of experience in the international automotive industry[2].

water stuff & sun has already received several prestigious awards, including the "Best CleanTech Solution for Energy" and the "Best Stand Out Performer" at the Global EnergyTech Awards 2023. The company has also been shortlisted for the Innovation Zero Awards 2024 in the category of Transport, Logistics & Supply Chain[5].

With their innovative technology and dedicated leadership team, water stuff & sun is a pioneer on the path to a sustainable and emission-free energy future.
