Simple bread ingredient enables revolutionary hydrogen battery

hydrogen He is one of the aspirants. Energy TransmissionIt allows sustainable energy, such as solar energy, to be stored and accessed when needed. The problem is that the material volatile and easily flammable It is. So storage is a challenge.

Rostock scientists now have an innovative way. Safe and stable storage It was developed by Hydrogen. To do this, they use an ingredient that many people probably have in their kitchen cupboard: Bicarbonate.

Bicarbonate is Sodium bicarbonateknown as baking soda Known. Used by researcher Potassium bicarbonate It is also a raising agent and is known as potash. It is mainly used for gingerbread And the honey cake used.

Harmless salt

along with Potassium bicarbonate Hydrogen reacts in the presence of A Motivational to FormatIt is also harmless salt, i.e. salt. Formic acid. Thus, hydrogen is “tamed,” the researchers explain. Formate can then be easily added. plastic containers Store and Tanker trucks He transmits. Research group leader Henrik Jung says:Basically like milk, beer or diesel.“

“We can release the hydrogen stored in the formate again at any time – with the same catalyst, in the same system,” he explains. Roy Sang PhD student Caroline SteinBoth are first authors of a scientific publication, in one. Announcement from the Leibniz Institute for Catalysis. That is, the reaction is Reverse it.

Researchers compare the power system to a battery… hydrogen It is loaded or unloaded. According to the press release, this system is particularly suitable for domestic use, for example rural area. There could be Wind energy or solar energy In stages where electricity is saved more than it is consumed electrolysis Production of green hydrogen, which is then stored in the form of formate.

The system operates at temperatures 60 degrees Celsius It allows simple and safe storage as well as uncomplicated transportation of hydrogen. Compared to other storage media such as Methanol or Ammonia It is format less toxic It uses less energy.

40 courses

Researchers have already managed to do that. 40 successful memorization and retrieval courses Demonstration and now plans to build a larger demonstrator. The goal is to commercialize the technology by the end. 2025Great importance is also attached to this process. carbon dioxide neutral be. published Study in Nature.
