Researchers develop hydrogen"battery" from salt

Hydrogen as a low-emission energy source

Efforts are being made worldwide to reduce the use of fossil fuels such as oil and natural gas. In addition to the finite nature of the deposits of these energy sources, the environmentally harmful emissions produced during combustion are viewed critically. An alternative and promising energy carrier is hydrogen. In contrast to conventional fossil fuels, this does not produce any carbon dioxide when burned. Furthermore, hydrogen contains more energy per mass than petroleum and natural gas.

Challenges in storing hydrogen

Commercially viable use of hydrogen has been hampered by challenges in storage, particularly due to hydrogen’s flammable properties. Science and companies are therefore looking for ways to make hydrogen transportable safely and efficiently. To the Leibniz-Institute for Catalysis has succeeded in developing a system that enables both chemical storage and release of hydrogen in a highly pure form. Formic acid and its salts, so-called formates, are used to bind the hydrogen. The principle is similar to that of a battery, whereby instead of electricity, hydrogen is stored and released again when required. It should be particularly emphasized that no expensive precious metals are required as catalysts.

commercial use

In cooperation with the Apex Group, an established provider of renewable energies, the Leibniz Institute is striving to put the research results to practical use. The possible uses of the new technology are as varied as they are interesting. For example, the process offers the possibility of storing energy from renewable sources and thus gaining a greater degree of flexibility. In addition, use for the supply of fuel cells in vehicles is also conceivable.
