Asahi Kasi launches green hydrogen production in Fukushima-launches

In March 2020, the Japanese technology group Asahi Kaili took the operation of his 10 megawatt (MW) single-stack alkali water electrolyist in the Fukushima Energy Research Field (FH2R) in Namie, Fukushima, Japan,. This gains another, important step on the way to the world’s leading provider of large-scale alkaline water electrolysis facilities for the production of green hydrogen. On the name of the “Aqualizer” he is the largest single-stack system in the world – one hour is enough to 1.200 standard cubic meters (NM3) green hydrogen to produce.

Already three years ago, in 2017, the order for the plant of Toshiba Energy Systems & Solutions Corp. The system was installed at FH2R as a technological development project of the Japanese Nedo (New Energy and Industrial Technology Development Organization). It generates 1.200 NM3 hydrogen per hour (rated power operation) and is thus the world’s largest plant system consisting of a single stack. After installation in November 2019, in March 2020, the test operation of the hydrogen supply in fluctuating power supply began. The start of the regular operation is planned for summer 2020.

Asahi Kaili qualifies for the construction of such a system through its almost one hundred years of long experience in the field of hydrogen production. In 1922, the company already used hydropower for water electrolysis to produce hydrogen for the production of ammonia. Furthermore, the Japanese technology company has been active in the field of chlorine-alkali electrolysis since 1975 and is today a leading full-service provider of key components, including catalysts, electrodes and membranes.

  1. I am very pleased that they operated about the problem with a purchase of hydrogen or battery
    Vehicles report. With their reviews and experiences in these areas they help many people in their decisions between these vehicles. Because they differ from each other and this information requires many people to make a real decision. Since the two types differ considerably from each other, regarding the influences on our environment. I would like to point out the problem of the composition of the batteries.Maybe they can report on this question, again information in an article summarized.

  2. Could someone please explain someone how to convert the so-called standard cubic meter in kilograms (as it is needed to locate a vehicle) – and the still never answered question is: how much is this cost for 1 kg of hydrogen or norm cubic meters really in production?
    I have the feeling that in such press releases only sounding quantities will be announced – without really bringing butter with the fish

  3. A cubic meter (1000 liters) (standard cubic meter with 1.03 bar, ie atmospheric pressure) hydrogen has an energy content of 3 kWh, which is about as much as 0.3 liters of gasoline.
    So if the largest system of the world can produce 1200 m³ of hydrogen, the ridiculous 3600 kWh of energy, or the energy content of 360 liters of heating oil / diesel.
    If the plant, which I do not know, but suspect, works with 70% efficiency, it consumes 5140 kWh electricity. From the 3600 kWh energy content go through the compression to 700 to 800 bar for vehicle refueling again 15% lost. So it ends 3000 kWh energy content in the vehicle tank, and this 3000 kWh are used in the system fuel cell / battery intermediate memory to 60%. A fuel cell vehicle can thus drive about 9000 km far, a BEV could be with the 5100 kWh Incl. Loading loss 25.000 km drive.

    Just to compare the dimensions: I live near the second largest petroleum fiber yard. This refinery processes 1700 tons of crude oil per hour (14.9 million t / year), which has roughly about 17 million kWh energy content. Around 70% of this are processed to gasoline, diesel and fuel oil, ie about 12 million kWh energy in the form of gasoline and diesel / fuel oil per hour. With this energy a car drives about 170.000 km.

    Who can expect it more accurately, I am learning!
