Interesting report from Drax on electric vehicles and how long it can take to repay the upfront carbon costs of EV batteries.

Really interesting report, thanks for sharing. Even with upfront carbon 'loading' from production an electric car is cleaner and will continue to get cleaner as electricity production continues to be decarbonised.
But, instead of simplistically thinking that EV is the answer, surely we should also need to start producing hydrogen from renewables PDQ. I see that JCB just signed a contract to buy renewably-sourced Hydrogen from Australia, for it to be shipped across the globe I hope that COP26 creates enough awareness to overcome the reluctance to push through the constrictions on national planning issues. With the environmental lobby blocking every Severn tidal power project (that could produce the equivalent of 3 nuclear power stations day in, day out with balancing from pumped-storage or hydrogen turbines or fuel cells) I'm a totally perplexed about the UK's approach to energy security and renewables. Surely we could have reliable renewable energy and make thousands of tonnes of hydrogen with any excess production - effectively storing energy for all forms of road transport and plant machinery?

Does it depend on which 'hand wash' you take it to..........

@Lodelaner Agree, it does seem crazy that we aren't exploiting the tidal ranges around the UK when we are an island with such a difference between low and high tides across the nation.

The government vitoed the plan based on a feasibility study. i can't do a link but if you Google Severn Tidal Power Gov uk the PDF is available on the .gov website. There are some concerns about damage to the environment but it looks like the cost/benefit doesn't make sense at this time. WARNING. This post may contain sarcasm. |

I’ve read it. 5 solutions were considered ranging from £7 billion to £34billion.
The summary is that “The costs and risks for the taxpayer and energy consumer would be excessive compared to other low-carbon energy options. Furthermore, regulatory barriers create uncertainties that would add to the cost and risk of construction. The Government believes that other options, such as the expansion of wind energy, carbon capture and storage and nuclear power without public subsidy, represent a better deal for taxpayers and consumers at this time.” However they didn’t rule out the viability of a private scheme - and bearing in mind that Hinckley Point C is currently running at £22billion and Sizewell C is likely to cost similar if commissioned with a life span of 60years (vs barrage having a span of 120 years) I think the conclusions should be seen through a different lens now.

I tend to agree. After reading, it looks like more government short sightedness. They've just kicked it down the road and instead given Chinese state owned companies billions to build our nuclear power stations.
What could possibly go wrong??? WARNING. This post may contain sarcasm. |

Not to mention that we are a small island, continually having houses built on is so where do you bury the spent radioactive rods that will take 300 years to become safe. There’s a housing development near Reading that can’t have open fires or BBQ’s due to leaking radon gas. |

The same transportation that also carries petrol / diesel powered cars? or parts that follow the same transports routes. More parts in a petrol / diesel powered vehicle as well. |

Also the creation of petrol and diesel, how energy intense is that. People always go on about the energy and the fossil fuels used for electric. But how much energy/co2 (or any other nasty chemicals) go into the ground or the atmosphere. Natural disasters when the front falls off a ship and tons of crude oil pour out.
At work I’ve increasing brought battery kit. We have solar to charge so pretty clean. But one big factor is not having the risk of spilling fuel. I’ll happily convert the 110’s engine to electric when that one goes pop. Not as if the 2.2 is a nice sounding engine. |

Yep, having "done" the first petrol station for Safeway back in 1992 and a few more to boot, there is quite a bit of equipment involved within the construction.... just saying.
And the ASDA brothers didn't come up with the concept of fuel and food / shopping at petrol stations |

Having a quick Google it takes 5-9 kWh per gallon to refine fuel. Then you need transport it using more fuel and pump it into the car using more electric.
That’s enough electric for for an electric car to do about 30 miles. So if we don’t refine fuel there would be a fair amount of electric not being used. So this thread has certainly made me think. |

It's probably methane rather than radon as the latter isn't flammable. Darren 110 USW BUILD THREAD - EXPEDITION TRAILER - 200tdi 90 BUILD THREAD - SANKEY TRAILER - IG@landroveranorak "You came in that thing? You're braver than I thought!" - Princess Leia |
