"Norway is using very high efficiency electrolysers + clean Hydro electricity to produce clean H2 at affordable price." The technology developed by NEL will give you 1 kg compressed hydrogen while using 65KWh of electrical energy. That is not what I call high effiency.The cost of electric power is estimated to 32,5 NOK (4 USD) for each kg of H2. The customer have to pay 90 NOK (11 USD) for each kg of H2. This price does not take into account the cost of investing in infrastructure. It is basically set to this level to make the cost of driving equal to the cost of driving diesel/gasoline cars. The building of infrastructure have to be sponsored by the goverment. And so far the Norwegian government have spent about the same amount of money on 4 hydrogen stations as they have used on the entire network of fast charging stations. Building a network of hydrogen filling stations will cost a lot of money. And I understand very well that BMW don't want to be part of this.
$1/kg H2, is a very optimistic number. If you invest in wind or solar energy you want to sell most of the energy at a highest possible price. You don't want to give away a lot of cheep power to make it possible to manufacture low cost hydrogen.To be able to produce and store 1kg of hydrogen you will need about 45 KWh of electric energy. That means that the cost of electric power alone will have to be less than $0.022/KWh if you don't consider the cost of investment.
HarveyD. 57$/KW means that a fuel cell stack of the same size as Toyota Mirai will cost 6440$. That amount of money will buy you a 65 KWh battery. And a 65 KWh battery will give you a practical driving range of 400 km, which is sufficient enough for most people. A FCEV will cost you about 9$ for each 100 km of driving compared with a BEV that cost you less that 2$ for the same distance. After 10 years of driving the FCEV will cost you 10000$ extra compared with the BEV. So I cant see why new batteries will need unreachable improvements to match these fuel cells.
Ethanol is a far better carrier of energy than pressurized hydrogen. Ethanol can be produced in many ways. One alternative is using sunlight, CO2 and bacteria.
One challenge when using this technology in transportation is how to recycle the LOHCs during tanking. You would probably need one tank for hydrogenized LOHCs and one tank for the dehydrogenized LOCHs. And you have to fill up one tank and empty the other. The article does not say anything about the storage capacity. How many kg of hydrogenized LOHCs is needed for storing 1 kg of H2? It is very positive to get rid of the high pressure tanks, in order to get better safety, and reduce risk of hydrogen leakage. But I expect that this solution will be more expencive than using compressed hydrogen.
If you read the details in the article you will see that the progress from the Toyota FCHV-adv model is not all that impressive. 6.5% more efficient fuel cells and 20% overall. Most of the improvements are based on a more aerodynamic design of the car. It seems to me that most of the efforts has been made to make the car less expensive by using as many Prius parts as possible. I don't know if this information is very valuable for other car makers. And I don't know why they insist to claim that the cruising range is the same as for gas cars. A typical gas car can drive > 1000 km on a full tank. Mirai can drive > 500 km. Toyota has been doing testing for winter conditions in Norway this winter, and claims that the range is up to 400 km. Practical tests done by a news magazine concluded with a range of 340-350 km.
HarveyD This is not a plant for producing hydrogen. It is a plant for producing hydrogen filling stations. Which means the equippment needed for doing on site electrolysis, storage and filling.
Hydrogen has no practical purpose for energy storage in Norway. With an annual production of more than 140TWh of hydro, it is no problem to balance the power grid. For that reason its just a big waste of energy to produce hydrogen. However there are some people who belive that it is wise to invest in hydrogen production, since electric power is cheep and hydrogen is expensive. With a price of 90 NOK (10,8$) for 1 kg of hydrogen, you can easily get a profit when you invest 65KWh of cheep electric, which will cost about 30 NOK (3,6$). And if you can get the goverment to take a good share of the investment costs it will be even better.
