Fuel cell company PowerCell Sweden AB will partner with Wallenstam AB, Midroc Automation AB and Hydrogen Sweden to launch a pilot study program on developing a system where surplus energy from wind and solar energy can be temporarily stored as hydrogen.

The purpose of the study is that it will lead to a joint demonstration project in 2016 next to PowerCell’s premises in Gothenburg, Sweden. The Vàƒ¤stra Gàƒ¶talandsregionen finances the feasibility study.

The electric power the solar panels and wind turbines generate satisfies the continuous demand for electricity, and the excess energy hydrogen is produced via electrolysis stored in the tank. The hydrogen can then be used in a fuel cell to generate new electricity and heat when needed.

PowerCell will, along with the Hydrogen Sweden; property manager and wind farm owner Wallenstam AB and Midroc Automation AB, a part of Midroc Europe Group, a comprehensive partner in the areas of real estate, construction, industry and environment, begin a feasibility study to develop a system where excess energy from wind and solar power can be temporarily stored as hydrogen which then together with PowerCell’s fuel cells provide electricity and heat in cloudy and windless days.

In the transformation “byproducts” occurs in the form of heat and oxygen that is possible to take advantage of. The heating is in a temperature range suitable for the district heating system and heating of premises. The oxygen is clean and has a high value if the right customer (e.g. hospitals) and a distribution method can be found. Hydrogen that is not needed into the grid can be sold as vehicle fuel and then has a higher market value than electricity into the grid on windy and sunny days.

PowerCell develops and produces environmentally friendly power systems for stationary and mobile customer applications. PowerCell has developed a modular system of fuel cell platforms producing electricity from hydrogen with only, heat and water as emissions. The fuel cells are designed to handle the hydrogen reformed from biogas, natural gas, biodiesel or standard diesel.
