Hope “gruner hydrogen” – research, test, save

What currently happens underground at 1000 meters depth at Rudersdorf ten kilometers of Berlin currently from Berlin, can only be redeemed: Kunftig should be 100 percent pure hydrogen to be stored – the climate-friendly energy carrier of the future. In any case, this is the plan of the provider EWE from Oldenburg, which operates the research project on the edge of the capital.

Build memory

In the cavern, according to the company, up to six tonnes of hydrogen can be stored after completion – sufficient to complete 1000 hydrogen cars full refinements. You already go into practice, said Ewe-expert Paul Schneider. The secure storage of hydrogen is tested, the contractuality of materials and the degree of purity after removal from the cavern – the subterranean cavity. A cavity with the out of a detached house is washed out of the salt rock in the marked floor.

On the earth’s surface is built in short the technology so that the company can begin with the so-called emission: with water from a nearby pond. "Hydrogen technology is to make rough-flat economically and renewable energy stored memory and thus usable around the clock", Says Schneider.

From renewable energies

Nationwide, some hydrogen research projects are running. The Federal Research Department demands basic research. "I liked Germany worldwide for the largest source of knowledge for the "grunn" Make hydrogen", Stresses Federal Research Minister Anja Karliczek (CDU). He is a central building block for the energy security of the high technology land Germany. Hydrogen is made by electrolysis: water is cleaved by current in hydrogen and oxygen. The electricity from renewable energies, it is called "gruner" hydrogen.

Energy industries

The Federal Government wants to continue to boost research in the area with around € 700 million to 2025. Among other things, the East German Chemical Region requires rough amounts of energy. In Leuna, for example, scientists want to find out with an electrolysis test and test platform, as gruner hydrogen can be transported, transported and stored as challenged as possible as possible.

Working on the project are in the plan, such as a speaker of the Fraunhofer Institute for Microstructure of Materials and Systems IMWS in Halle says. The pilot plant is intended to start the information as planned this year. In it, scientists of the Fraunhofer Center for chemical-biotechnological processes CBP (LEINA) and the Fraunhofer Institute IWMS from Halle.

Saxony-Anhalt also has the claim to become a hydrogen model region in Germany. "The exciting is how it can succeed in converting an energy-intensive industry climate-neutral", says a spokesman for the Magdeburg Ministry of Economic Affairs. Under the name of "Hypos" Works a network of around 130 companies, institutes and research institutions. The task is to engage for the production, storage, distribution and broad application of green hydrogen in the fields of chemicals, refinery, mobilitat and energy supply.

Lausitz after the lignite

Also elsewhere does a lot. In Lausitz sets a network "Put through" On hydrogen specifically for the time after the lignite. In Gorlitz, the Land Saxony and the Confederation support the establishment of a research platform for hydrogen technologies with 30.5 million euros. Under the name Fraunhofer Hydrogen Lab Gorlitz (HLG), it is one of the projects for structural change in Lausitz. New technical approaches are to be developed and tested along the entire value chain. In Rudersdorf Ewe with its investment project amounting to 10 million euros according to own information is well in the plan. Four million euros comes from the company, the remainder from the national innovation program hydrogen and fuel cell technology as a claim by the Federal Ministry of Transport.

The rock salt layer begins in Rudersdorf at 600 meters depth and reaches up to 3200 meters in the earth. The salt comes from a sea company, that there was 250 million years ago in today’s Brandenburg. In the coming months, the technique should be built to start the emergence – the hoping of the rock salt – says EWE project manager Hayo Seeba. Over an existing about 54 kilometers long underground brine, the water is passed to Heckelberg, where in rough depth of nature is already salted water.

At the site EWE has already been memory experiences since 2007. Two of the 37 natural gas caverns of the Lower Sachsian company are there. The already existing hole was used for the construction of a third test cavern.

According to companies, EWE has 15 percent of German cavern storageers, which were suitable for storage of hydrogen. EWE wants to save 3 to 4 terawatt hours of hydrogen a year – about 100.000 tons. This allowed 16 million hydrogen cars to be filled out. If everything works well in Rudersdorf, findings from the project could be transferred to caverns with 1000-fold volume. Efficiency ames how the company emphasizes.
