Wonder who the gas suppliers are!!
Hmm, AFC have just finished a hydrogen fuel cell which can use ammonia.
Ammonia has 3 or 4 times as much energy as hydrogen in the same volume and is not stored at potentially dangerous high pressures.
This technology is being attached to Electric Vehicle re-charging points initially and could become a very big deal as part of the renewables/carbon reduction mix.
Interesting article this…
EIA reports the average cost for utility scale battery systems to be about $1500 per kWh. At that rate the batteries needed for backing up a solar or wind facility for three days cost around 30 times as much as the RE facility. But wind is often unpowered for more like seven days, during huge stagnant high pressure episodes. Thus the backup battery cost is more like 100 times the wind farm cost. Batteries are not feasible.
The major intermittency problem is season-to-season, especially saving up enough for winter. We do not have a way, today, of storing energy from one season to another, short of making it into a liquid (such as ammonia), and storing the liquid from season to season. This would be another way of driving up costs of the overall system. It has not been included in anyone’s cost calculations.
So how come Tesla gigafactories are claiming $125 per kW hour?
Others say that the price is far lower than quoted in the article nad are forecasting much lower prices…
By the way, the one way to store energy from season to season, ‘using, say, ammonia’ is already with us with AFCs new hydrogen fuel cell technology and products about to hit the market. They are only going to improve and hopefully in decades to come we will save oil for the very useful things it does rather than burning it.
Nice post eadwig…
Wonder if this is the same eli akaso as our eli akaso!!

If you look at tanker and other maritime trade magazines they are full of stories to move to hydrogen fuel cells and batteries to get around new emission regulations with some due to start tests within months.
Tankers and ships generally use about the dirtiest diesel oil there is and many ports have already banned some older tankers due to the pollution they trail in with them. These tend to be older tankers so they are simply being scrapped as retrofitting them isn’t worth the investment as tankers have a time limit on their life time anyway - 25 years I think it is but there was talk of reducing that to 22 then 20.
