Hydrogen Economy?

Thanks for taking the time to explain, that's the reason forums like this are so great. You would have thought with all the combined knowledge and experience in forums like this that we haven't solve the world energy problems by now maybe the government do not read these threads, too busy on netmums

Is LFP what I was hearing about in the news a few years back. I do rem'ember a science programme on Radio 4 talking about advances on battery technology where you could charge to 80% in a matter of minutes and at a cost of pennies?

Thanks again

BTW they are trialling eco street lights in a village near us (Glinton, UK) with ultra low power bulbs and solar/wind generators. Can't find any technical info on it though.

Well LFP or lithium iron phophate batteries have been around for a few years, and are what a lot of the new electric vehicles are using.

As far as cost to charge up is like any other batteries as it depends on what size they are. For example a 10 Kwh lead acid battery is the same as a 10 Kwh LFP. They both cost about a 1 USD to charge up. Difference is a LFP can be charged up in 30 minutes or so if you have the source or charger big enough to do it with. A lead acid battery would take 8 hours or more as they cannot be charged any faster than about C/8 to C/10.
