Fraunhofer ISE Starts Operation of New Hydrogen Feed-In Plant

25.01.2018

In its role as a flexible energy carrier, hydrogen is an important element of the energy transformation. It facilitates the transfer of renewable energy between the different sectors of, for example, mobility, industrial raw materials, heat or gas. The Fraunhofer Institute for Solar Energy ISE is working to further develop the key technologies for sector coupling, for example, hydrogen generation by PEM electrolysis. Together with industry and energy sector, they are testing the application of these technologies in the practice. The results shall serve to establish important fundamentals on the use of this central energy carrier of the future.

"In an energy system without fossil fuels, the fluctuations in electricity production from renewables must be balanced out,” says Dr. Christopher Hebling, Division Director of Hydrogen Technologies at the Fraunhofer Institute for Solar Energy Systems ISE. “Flexible electrolyzer systems for hydrogen production are gaining importance as one solution here. The existing natural gas grid can be used for long term storage.”

Fraunhofer ISE

As part of its research work, Fraunhofer ISE constructed and put into operation a hydrogen generation plant for feed-in to the natural gas grid. This plant is located in the institute’s laboratory on Auerstrasse in the northern industrial district in the City of Freiburg.

The work at Fraunhofer ISE is supported by its project partners badenova / bnNETZE and the College of Applied Science Offenburg. The construction and operation in 2017 was supported with funds from the State of Baden-Württemberg through the project carrier Karlsruhe Institute of Technology KIT within the project “Kommunaler Energieverbund Freiburg” (Communal Energy Network).

Research System to Investigate Operation in the Distribution Grid

Since August 2017, the plant at Fraunhofer ISE feeds hydrogen into a natural gas supply pipeline of the communal distribution grid. Gas customers in the northern industrial district and in Gundelfingen receive gas with a mix of 2 % hydrogen.

“The targeted sector coupling makes it possible to increase the share of renewable energy in the system, and thus demonstrates an important building block of a sustainable future energy supply. As an energy and environmental service provider, we are already collecting first experiences in order to best support the ecological efforts of the region,” says Richard Tuth of the Innovation Funds and Environmental Management of badenova.

In the project “Kommunaler Energieverbund Freiburg,” complex algorithms for operating the plant were developed and tested. These algorithms for the management operation are based on a model predictive control, which means the operation is optimized daily using a simplified simulation model integrated in the algorithm.

The tested algorithms aim either for a maximum use of local green electricity or the lowest possible electricity price on the day-ahead market of the European Electricity Exchange (EEX) or rather an optimized combination of both.

These operating strategies were developed in simulations, then tested and subsequently transferred to a real plant in the practice. Even though commercialization through Fraunhofer ISE is not intended, the plant is operated based on economic and ecological aspects and validated under real operating conditions.

The plant is conceived as a research platform for optimizing the operation of the distribution grid. Even after the project ends, the plant shall continue to serve as a platform to validate different operating strategies as well as to develop and test new components for the natural gas grid.

At present, it is difficult to operate hydrogen plants with economic efficiency, since the legal regulations governing hydrogen are disadvantageous compared to other technologies. By adjusting the legal regulations to facilitate a more just market entry, however, these technologies can then dramatically contribute to the reduction of carbon emissions in the heat, mobility, industrial raw materials and gas sectors and advance the energy transformation.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
