Renewable hydrogen can make our mobility green. For this, however, the costs must decline. How does that work, develop energy industry and research currently in an industrial power-to-gas system in the southern German borderline Wyhlen. The megawatt plant has been operating in April 2020 for four months and works reliably. Also a research electrolyeaner connected thereto is very successful. The Center for Solar Energy and Hydrogen Research Baden-Wurttemberg (ZSW) coordinates the project. Operator of the commercial facility is the energy supplier Energy Service AG.

The power-to-gas system with an electrical connection capacity of a megawatt generates renewable hydrogen with the stream from the Rhine hydropower plant in Wyhlen. Since a use of the public electricity grid is not required, network charges and the EEG levy. In addition, compared to power-to-gas plants based on wind or solar energy, high full-load hours can be achieved because the hydropower is practically available around the clock. This further improves the cost-effectiveness and quickly enables extensive operating experiences.

Since the beginning of December 2019, the plant has been regularly running and has since then since 1850 operating hours. The monitoring system attached by the ZSW, which misses all essential components and subsystems, works flawlessly. The system works fully automatically at full load and in different part load states in 24-hour operation. With the help of a remote transfer to Stuttgart and automated data evaluation, the ZSW monitors the operation. The scientists identify, among other things, the efficiency of the entire system including all subsystems. The overall efficiency of electricity to high purity, 300 bar-compressed hydrogen is currently up to 66 percent based on the condensing value of the gas. In addition, researchers examine aging effects and derive improvement potential from the data.

So far, the plant filled 62 trailers with fuel cell compatible hydrogen. Each of these transportable containers holds around 300 kilograms. Per day, the system can generate up to 500 kilograms of hydrogen. This is enough for an average daytime reception of more than 1000 fuel cell cars.

Reduce costs of electrolyzers for the industry

The research project docked to the commercial plant is successful. In a research facility, the scientists sampled in parallel operation for commercial plant improved electrolysis blocks with a maximum of 300 kilowatt performance. You should further reduce the hydrogen price. But companies can also test and optimize components there, to transfer them to their products later. Thus, the project supports technology transfer to the economy. Last year, the ZSW and its research partners already made a first success during the test of the system: with new electrode coatings, the researchers reached 20 percent more power density compared to the electrolysis blocks of the industrial plant part. This means: For the same power, less room content and material are required.

As the investment costs are also based on the volume of construction and the electrolysis blocks accounting for around 40 percent make the biggest cost share in the conversion of renewable electricity, progress in this area automatically reflects on the hydrogen price. For manufacturers of electrolysis systems, the development is therefore an important factor for further cost reduction. The long-term goal of the ZSW researchers and energy service engineers is to halve today’s production costs of current-based hydrogen.

Twelve partners are on board in the project on board, four of them from research: In addition to the ZSW the German Aerospace Center (DLR), the Fraunhofer Institute for Solar Energy Systems ISE and the DVGW Research Center at the Engler-Bunte-Institut of the Karlsruhe Institute of Technology (KIT). In addition, there are eight-associated industrial partners: Energy service AG, the Daimler subsidiary Nucellsys, the Zwerkverband RBB BOblingen, the Stadtwerke Sindel- began, the telescopic operator Terranets BW, the electrolyzer manufacturer McPhy Germany, the membrane producer and plant manufacturer Fumatech BWT and the National Agency for New Mobility solutions and automotive Baden-Wurttemberg (E-Mobil BW).

  1. Great waste of hydropower, but the Frenchman can secure our basic load thanks to atom flow and we do not know anyway where our money.

  2. Transportable hydrogen
    For free solar energy can be harvested worldwide and
    also used in such industrialized zones, where the sun does not appear in abundance.

    Hydrogen energy is storable, pipeline bar and transportable exactly like petroleum and gas.
    When hydrogen is generated and traded worldwide worldwide, change at most
    The places where the energy instead of fossil from the earth, regenerative from the sky.

    The efficiency of converting free and quasi unreal global solar energy in
    Storatable waterstake then does not play an essential role for the meaningful feasibility
    a worldwide hydrogen industry.

  3. If I read the whole comments here so again is once again realizing that here obviously there are two bearings:
    The one advocate the hydrogen – the others are against it. Ok, I would have a very different simple question to the article:
    How much is now a kilo of such produced hydrogen for the end customer right now ?and if you do not pay the state-specified ten euros price?

  4. In my view, research associated with fuel cells has progressed massively in the last two years. I have been working on FCEV since 2017. Please do not look at Mirai and Co. These are really outdated.
    Unfortunately, this technique is not so promoted as the BEV. These are not sooo too.
    How about a restriction to 3kg lithium per car ?

  5. H2 is set worldwide as a storable energy source in the energy industry. There can be various gentlemen there above what they want. You are not an experts for energy industry, but want to comment all negative what has to do with H2. Above all, the men are unaudirable. No matter what you give to facts, that does not interest you. Incidentally, research is always useful, no matter what it works. Only right when it comes to one of the most important topics in the world. And that the hydroelectric power station is used has the simple reason that the German rules is ee-hostile and you can only save network charges and EEG levy. Is in text when you read correctly. If you can use electricity economically, you should do that. So everything speaks for BEV. But in the future extreme amounts of electricity must be stored to achieve a 100%-sea system in 2050, H2 will be available in large quantities by electrolysis. Whether part of it will land in a part of the future cars is still uncertain, but quite conceivable.
    This is the simple and clear reality against the usually only carbonobbyists writing in energy.

  6. Hydrogen production made of renewable electrical energy is waste and has no future.
    As long as not enough electricity is there, you can terry the topic anyway. Although the projects are currently running everywhere in the country (stadeworks, waste incineration, sewage treatment plants), because politics discovered the topic for themselves (as a jewelry) and the subsidy castle pours.
    The whole thing is not to be overparted with bigotry if our Lord Altmeier at the topic opposes her mouth. All who are really on the subject: “Convations, taxes, donations, as they are introduced by the rulers, prevent usable development.”EE expansion, PTX, everything is currently being massively hindered.
    Hydrogen is needed, but then be delivered by the Petro and Chemical Industry. Do not make any illusions about solar parks in the desert O.a.
    Hydrogen is obtained by the methane pyrolysis. As soon as the funding programs have enabled the ScaleUp to the required size, the old known (Wintershall DEA, BASF, refineries Younameit) will board.
    All SMEs, Stadtwerke, Idealists are then confronted with a market price for hydrogen, which drives you the fun from the face.
    How did our husband said. EnergyKomissar Ottinger in conversation with the lobbyists of energy suppliers: The underwire our energy transition. Shortly thereafter, electricity prices in Keller and the network usage and duties in the amount.
    That will be like that.

  7. The instantaneous situation is not relevant to the research, but the future and the end target 100% -E system up to 2050.
    In a 100%-sea system, no room is for natural gas and is more expensive for CO2 levies anyway. Current tendering result from Qatar for a large PV system is a power price of sensational 1.47 cents / kWh. Then we come to a H2 price of 3 cents / kWh in production. These are the co-decision parameters. Namely, economy, not just efficiencies of plant components. The sun sends enough electricity to the earth. We just have to “talk” as clean as possible. Incidentally, in the 66%, the print generation is already included in 300Bar.

  8. So far, it was argued: Hydrogen from excess WK, therefore useful. What has changed now?
    Obviously, the conversion of H2 with WK is not so far. At the above-mentioned system, it is also about gaining findings.
    When is to be expected with hydrogen from excess wind and solar energy?

  9. It’s not about wind power, but about renewable energies as a whole. WK and PV complement each other very well. Because with a lot of sun is often little wind available and vice versa. At some point, however, the proportion of EE is so extensive and fluctuating that you have to start saving. For economic reasons, this will expand in parallel. In principle, it is an optimization task for scientists. It is estimated to be stored at least 20% of the years of the year in the form of H2 and then, if necessary, to produce electricity and heat again. Incidentally, much more heat is needed as electricity. From electricity, however, you can make heat and is therefore usually the higher quality energy form. I am convinced that we will invest a lot in Agro-PV in the longer term, since 100% area use approx. 160% will (80% Agro + 80% PV). We have a lot more than we need. PV is new major power plants, the most cost-effective form to produce electricity.
    And I can also imagine that after elimination of EEG promotion in old wind turbines, there are own electrolyzers installed in order to be able to use energy economically. Until H2 is really strong, certainly a few years. That depends on many factors, especially political. This time you have to use to develop research and H2 technologies even further. This technique is also a possible international bestseller for German mechanical engineers. We have to be at the very beginning.
