Klunk, I don't suppose Taskmaster is far off. A simple Google search will give you the basic values required to produce hydrogen and the energy stored in hydrogen. Perhaps they do need 40 odd panels to do the job, generating power for two weeks to provide enough hydrogen for one day's racing, but we're missing the point. The point being that AFC have consulted with Extreme E and asked to design a bespoke system that generates completely green hydrogen using renewable energy, which provides an effective store of energy to power the EVs for race day.
Now once that solar system is paid and installed it can be used anywhere to generate hydrogen for free. Office and factory roof tops for example. Used to power and electrolyser fed with water will generate Hydrogen at minimal cost, which can be used as a store of energy to utilise in a fuel cell for rapid charging. Solar on its own is perhaps not enough for rapid charging unless you have a solar farm of many many panels. Now this is not to say that this would be the only requirement for hydrogen of any business with an EV fleet but it certainly demonstrates the feasibility of the system and can easily be applied with an ammonia cracker to give a plentiful energy store and delivery system with the low cost hydrogen making up 10, 20% of the fuel requirements and thus reducing the hydrogen bill.
And thats what its all about ! a simple demonstration of what is possible and AFC have developed the bespoke system. The rest is irrelevant as long as AFC and Extreme E are happy.
