I don't want to labour the point on subsidies, whether they be tariffs, R&D development funding or tax breaks, this issue is sustainable credentials

If a wind turbine/solar panel etc charges a battery the whole cycle is CO2 neutral and can make this claim.

If the battery is charged by a fossil fueled source it can't - simple.

Unless the emissions of the charging generator are less or equal to the item being charged, if not, it is a waste of time. (and money) Life cycle assessment needed !

Long journey home from the cricket

I would like to think that battery and energy storage is helping the climate challenge-simply because it will allow solar and wind energy to be stored as against often dissipated.There is clearly a long transition from fossil to renewable but you have to start somewhere.The johann Cruyff arena is a case in point-our batteries store energy from the solar panels on the roof so that the whole stadium can be run off grid at best, but also store energy when there is low demand.

How much to replace battery system in a standard car because if they are anything like lithium batteries in power tools their charge holding power does drop off after a while.

I have no idea Alan but we use Leaf batteries from Nissan which originally had an expected life of maybe 5/6 years.What we are seeing is a growing market in second life batteries which are still very efficient and could be used in energy storage facilities.

Leaf batteries seem to be lasting around 8 years in cars-much better than expected.

Cell prices are coming down very quickly as technological advances have some momentum.This means the price per KWh is coming down very quickly-probably halved in last couple of years.

Battery energy storage and the portability of it opens up a whole new world.

Various scenarios have been generated, especially round community usage where multiple vehicles could be used to power the local community center for events, even stadiums, the possibilities are endless. Why have a propane cylinder delivered, why not a battery, where the delivery truck is also the charging unit.

You seem interested in the space so have a look at Bladon Jets-I’m a shareholder in that too and it’s poised for greatness.Based in Coventry.

Africa is a huge market for any kind of portable energy-lots of remote areas with no grid

The whole sector has a bright future, and the UK is up there in the World with development.

There is already 000's of jobs being created and 00's of new star-ups, which is great news.

But, already the warning signs are there that the full Ethos about what the market is about are being forgotten.

Massive investment is being made to de-carbonise our energy generation infrastructure, mostly at the taxpayers cost. Ground-source is a failure, the RTFO is floundering, Solar has been a get rich quick scheme for the suppliers and installers and many of our large wind-farms are being paid for generation and are not even connected to the grid. Battery power will fall into the same hole as investor capital is part of the engine and EPC Contracts and Non recourse funding will be used. BEIS need to tighten up their act, and ensure the policy balances job creation and tax revenue v the objective.

If they do, it is win, win............
