Dave Thornton Earl Bramley-Howard An excellent link, positive news of the many many reforestation projects that are happening right now. That and renewables being cheaper than fossil fuels are two of the most important things we NEED to be fast growing!.

Earl Bramley-Howard we need slow growing trees though – like broadleaf hardwoods – not just miles of fast growing pines.

Dave Thornton Earl Bramley-Howard Yes but parts of Broadleaf Forest on the outside edges could be planted up as Forest Gardens, so the Forests would serve both Environmental purposes and produce a lot of food!.

Dave Thornton The search engine ‘Ecosia’ has just passed 40 million Trees planted. Then you have ‘Cool Earth’, ‘The Great Green Wall of China’ and the ‘Great Green Wall of Africa’. Scotland are replanting the Caledonian Forests, even Iceland has reforestation projects. There’s plenty of reason for hope!.

Dave Thornton I still think using Hydrogen via a fuel cell is the best way to store the energy for EV. Hydrogen via Electrolysis is a good way of storing energy but without the need for Lithium, Cobalt or other hazardous materials/chemicals needed to make Lithium Ion batteries. Fuel cells on the other hand only need to convert energy, and recent breakthroughs with Fuel Cell technology has produced Fuel Cells that are made from a Ceramic made from non mined materials such as Sand.

Earl Bramley-Howard How can hydrogen be the “best” when the full cycle from solar panel/wind turbine, to gas, to vehicle, is only 35% efficient? Even if they get that up to 50% efficient, it’s still nothing like the 96-97% efficiencies of solar/wind directly into lithium batteries, even when you have to have battery to battery chargers to get the electricity into the vehicles from the ‘storage’ batteries.
A service station (or home) could store energy separately in super-capacitors for rapid-charging directly into vehicles. Sure for certain specialist forms of transport hydrogen may be a useful stop-gap till battery solutions are more developed. But even those could be better addressed with bio-gas solutions because methane is also a form of hydrogen (CH4).

Dave Thornton Once again I’ll have to agree to disagree with you, I don’t know how much better batteries are now, but I read many years ago that you only get 1/50th of the electricity out to what you put into a battery I’m sure that % has got better but till we have batteries that can charge like a super capacitor. I don’t see that % getting significantly better, then you have hazardous materials in manufacture and disposal!. Also there’s plenty of times when Wind Genes are switched off when there’s an excess of electricity, also at night time when electricity is really cheap cos much less of it is needed. Instead of turning off turbines why not do( as they are currently doing on the Orkney Islands, and Aran is likely the next Island) and produce Hydrogen from excess renewable energy?.

Earl Bramley-Howard “Efficiency
The battery is highly efficient. Li-ion has 99 percent charge efficiency, and the discharge loss is small. In comparison, the energy efficiency of the fuel cell is 20 to 60 percent, and the ICE is 25 to 30 percent. ”

Dave Thornton But I think it’s better to use natural and non hazardous materials as apposed to what is used in batteries( even IF they are that/and more efficient). Being Green is about diversity, the future will no doubt involve a variety of fuels, engines, motors etc, places like the Orkneys that nearly always have an excess of electricity, it makes sense to use that excess energy to make Hydrogen. Which is making money for the Islanders and creating a local Hydrogen economy. When you say Lithium Ion batteries are 99% charge efficiency, do you mean only 1% energy loss when charging one of these batteries, so you get out 99% of the energy input? Cos I’m pretty sure batteries are knowhere near that efficient!

Earl Bramley-Howard I don’t know why you refute a scientific battery education website?
99% efficient means that 99% of the electrons that you put in stay there. Output efficiency depends of what it’s put through when it comes out. For example most Pure Sine Wave 48v inverters will run at about 98% efficient so the round cycle in and out is about 98.5% efficent. Put 1000 Watt hours in, and get 985 Watt hours out.
The cycle depth of discharge varies from battery to battery. The most recent lithium can be discharged to about 20% without any difficulty (meaning they always retain about 20% – so a 4kWh battery will hold about 3.2kWhs of useable electricity). GEL lead deep cycle batteries can be discharged to about 50% remaining, so lithium’s 20% remaining, is a big improvement – and they are lighter and smaller.

Dave Thornton Earl Bramley-Howard And?, are you saying 8 years on and nothing has come of it?. Cos Bloom boxes have been installed by Google and 2-3 other big multi nationals. Which according to Google etc own reports the ‘Bloom Boxes’ are working well, and as they should!.

Dave Thornton I’m not saying how much energy put into a battery ‘stays there’. But how much more energy has to be used to charge a battery to how much you get back out. I don’t believe you get 99% of the imput energy, back out, to do that there would need to be little to no resistance from forcing the energy into the battery. Also the ( hazardous)materials in Lithium Ion batteries is a big concern even though they can be recycled. Lithium is not renewable and is expected to be exhausted in next 50 years. Whereas Hydrogen and the Ceramic fuel cells( made from sand) to convert it to Electricity are both renewable!.

If a PBR, a Pyrolysis machine,! a medium sized Turbine (of some type) for compressing Air AND making electricity for EV/CAV, and a facility for making liquid fuel from old Veg oil, was all combined, we could have multi Green fuel Vehicle fill up stations in each village a d town etc, for all the future green fuelled vehicles!.

Dave Thornton Ali Chakir They say 60 of these devices are needed which is the number they plan on building, they are getting a lot of funding so I don’t doubt they will do what they plan. But first they want to see how this first one works in situ and use it to make modifications to following ones so they evolve in effectiveness!.
