Expert manifests itself: “Hydrogen Future or Bridge Technology?”

Expert manifests itself:

Series founder and Tech investor Frank Thelen answered the question on LinkedIn for the question of whether hydrogen is a future – or only bridge technology. We were able to share this article on yesterday Thursday on our portal with you. Also on LinkedIn has become Dr.-Ing. David Wenger to speak, his sign recognized expert for hydrogen technology and founders of several companies in this area – his answer to the question of Thelen we did not want to consider you.

Dear Frank Thelen,

Thanks for the article. After 16 years at the forefront of the industry in the industry, I trust myself some assessments.

I have learned the following sentence: “If you ask the wrong question, the answer does not matter.”That means in this context: Hydrogen is neither forward-looking technology nor bridge technologyhydrogen is already a basic material today. There are about 500 billion standard cubic meters per year, which are about 50 million tons produced, especially for petrochemicals and fertilizer production. Hyberstuff is an elementary basis of our worldwealth by the Haber-Bosch procedure, with which artificial fertilizer are produced. And that for over 100 years. From the sex appeal of a “Fancy-Ki Autonomous Electric Drone Startup” is far away. Hydrogen is daily bread for chemical plants around the world.

In the production of this hydrogen, about 500 million tonnes of CO2 are emitted per year. That is much. And if you would now produce this hydrogen through renewable energies and electrolysis instead of natural gas, you would save this CO2. And that’s what it’s about the “wumms package” and the national hydrogen strategy equipped with nine billion.

The world market leader for electrolysis facilities is called ThyssenKrupp. No company, which is suspected, to be a sexy investment insider tip. But suspected a company that creates or at least receives jobs in the Ruhr area. This motivates politician of all couleur. The second motivation is that the EU refers a third of natural gas from a single company – Gazprom -. This is a gigantic geopolitical dependency. To reduce this makes great sense.

Whether hydrogen in traffic prevails, remains to be seen. Essentially, it depends on the further development of battery technology. The question is less crucial than one could mean because of the heated discussions.

Exciting, I find that many people quote the pictured graphic. It is so catchy that you hardly come up with the idea to question you. And yet she is wrong. why? It starts with “100% renewable energy”, D.H. With a stream offer that is just there. But that’s not so. Renewable energies fluctuate, and supply and demand can not be automatically covered. It takes a memory in between. These stores are either gigantic battery parks (I did not believe today) or a chemical energy storage. And that is hot hydrogen. The efficiencies will level so.

Germany will not be able to produce enough renewable energy according to compliant expert opinions. We will depend on imports. How will it go? By cable? We do not even do it to put a cable from northern Germany to southern Germany to distribute the excess wind stream. Accordingly, it is unlikely that we place one of Tunisia about Italy to Munich. Desertec tried and failed. Here, too, hydrogen will be the way, and the currently politically preferred (non-EU) countries are Morocco (Sun + Wind) and Ukraine (Wind). The pipelines are there, you have to reduce them “only”.

For a long time: we should discuss the topic in detail, also with the inclusion of the question of whether Germany is as an innovation country on the wrong track and we tuned things, while Hyundai invests 6 billion in the topic and is already world market leader for fuel cell systems today.

About the author: Dr.-Ing. David Wenger is a globally recognized expert for hydrogen technology and founders of several companies in this area. In the last 16 years he has driven up with Wenger Engineering GmbH from California to Australia for almost all companies in the industry developments, especially in the field of hydrogen production, storage and gas stations.

In order to further promote the topic, he founded Mission Hydrogen GmbH in the beginning of March, which has quickly become a world leading hydrogen marketing company. On the weekly hydrogen webinars with representatives of the German Bundestag, the American Energy Ministry or Companies such as Linde, Nel or Loop are on average over 1.000 participants.

On the 08. October organizes mission hydrogen the world’s largest hydrogen conference, the Hydrogen Online Conference with around 10.000 participants. The live ticket is free. www.Wenger Engineering.de, www.Mission Hydrogen.de, www.Hydrogen online conference.com.

  1. Well, there is finally one of the idea. Each chemistry student white after the first semester: hydrogen is produced larg-indit and to a large extent to ammonia (Haber-Bosch process at 300bar and around 700 ° C, so you can think what that costs energy) and then too fertilizer implemented. That’s nothing groundbreaking new but will be operated for decades.

  2. Is it a miracle that someone works in marketing, wants to hopes?

    But this will not be better, more beautiful or environmentally friendly. The hydrogen is produced to more than 90% of oil or natural gas.

    And that will not be changed in 5-10 years, as the EE is not consistently expanded. See Bayern with 10h …

    And which generate the continuous transformation of energies in the hydrogen chain with BZ nonsensical losses has already realized everyone.

    In the end, the use will decide and the hostility.

  3. We write here in a portal for e-mobility. Since often the impression is conveyed that the fuel cells could replace the BEV in width, these core kits are crucial for me:

    “Whether hydrogen in traffic prevails, remains to be seen. Essentially, it depends on the further development of battery technology … “

    I think, that’s why Mr. Thelen was also. The valuable green hydrogen, as listed in the article, is indispensable for so many applications. But he is extremely inefficient in a broad mass for car use extremely inefficient and thus little. It’s the pure waste.

    Who in contrast to a BEV a highly complex fuel cell car with U. a. want to buy high maintenance, should it be happy to do and then carry the consequences, whether he comes up with them or not.

    As progressively the battery technology will be, Tesla will hopefully learn about the announced Battery Investor Day as a benchmark.

  4. At the latest when the battery technology has arrived at about 600Wh per liter, there is no reason to use a fuel cell for the mass. And I consider this energy density for quite realistic in the next 5 years, as there are more and more news about new battery technology and also of renowned companies / institutes / persons.

    Do not oppose me at all. That’s an argument according to the motto, we always did so.
    Why are efficiencies leveling, just because additional memory (as always these appears) will be needed if the proportion of renewable energies is increased?
    The table makes it clear that purely for the electromobility hydrogen makes little sense for cars – very well for all other purposes.

  6. The memories do not necessarily have to be gigantic battery parks (although on the other hand nothing is to oppose).
    Today, more and more solutions are looking for together with the economy. Z.B. Melzbader, which are heated more strongly for electricity overlay than necessary and then can go briefly from the network with too little electricity. That’s exactly what works for big cooling houses.

    In the future, car batteries become buffer buffers for the network. Who really can guarantee 1 million. Take advantage of, as has been offered by Toyota for the Lexus UX300E or Proace Elektro? So many charging cycles are wonderfully suitable for the feedback.

    There are also interesting storage projects that are not yet in the focus of Openness. Z.B. Who water reservoirs are explored, which are to be sunk in the sea. With excess, the water is pumped out against the overpressure on the seabed and with too little stream it flows back into the tanks via a turbine.

    Last but not least, the question arises as to whether EE is not an oversupply. The electricity costs in production as good as nothing and wind turbines can be removed from the net in seconds. It’s the same with PV systems. Conventional power plants can be controlled much worse and slower and cost significantly in operation.

  7. What makes the hydrogen expert here is to compare apples with pears.
    The criticized graph shows the efficiency of the various vehicles, but Wenger then talks about stationary storage of energy.
    For stationary storage, hydrogen is certainly meaningfully usable, but for cars, it is basically more efficient to renounce a two-time transformation of the energy.

  8. Some points are questionable to inaccurate: “Experts believe that the required amount of energy from EE can not be generated in Germany”. How high is the energy consumption estimated? How high the power component?”As well:” The power consumption for the production of the battery equates to the efficiency disadvantage “. How high is the power consumption for making a battery? (per kWh capacity)
    and: “Current must be cached.”Why must power from wind and sun have to be cached if needed exist? That definitely does not true!
    With a battery of 40 kWh and a realistic mileage of 180.000 km, the efficiency advantage is well over 50%.
    Of course there are other proportions. (Z.B. Battery with 60 kWh and a mileage of 150,000 km. In practice, however, it is already well over 300.000 Km reached) In a general assessment, however, should be expected with averages.

  10. Interesting: The topic of storage efficiency gains the hydrogen here because the Lord is not battery storage believe. If he would rate both technologies right away, then the graph also called here: Hydrogen is always inefficient, no matter whether in the vehicle or as a memory.

    Reality is: Battery storage are massive in the coming, they serve to compensate for daily EE fluctuations and are the perfect complement for photovoltaics.
    Hydrogen storage will come to use seasonal fluctuations. At some point in the future. Because green hydrogen is foreseeable much too valuable than that he would bunk him half a year.
