Boris is getting worried about how much acreage is being giving over in the UK to the process of growing grain to produce Biofuel . With the ongoing war in Ukraine there will be a serious shortage of grain to supply the worlds populations. He apparently will bring the the subject up with world leaders ASAP.

So it seems some sort of sensible argument on burning food to burn to give less energy may be about to happen.

As short term crisis management maybe worth looking at

But isn't the Ukraine crisis also making the fossil fuel (which would replace the biofuel) hard to get hold of?

Long term the IC engine ban, once extended to trucks, will pretty much make the market go away, apart from possibly aviation fuel

r&d is speeding up for making aircraft engines and motors work from Hydrogen including HGV engines which they say full evs are not a good idea in HGVs, batteries are too heavy and do not have the range for long haul, so this crisis is helping to speed up research in Hydrogen (green at that)

Large quantities of hydrogen will call for quite large amounts of energy to generate ?

If its wanted that badly it is up to the R&D group of engine makers to sort out, which apparently is being looked at in great detail for companies to develop and use.

Don't forget other uses such as marine engines (tons per mile for large vessels), farm tractors, JCBs, mobile cranes, small power tools such as chainsaws, hedge trimmers, cement mixers (yes, some are mains electric or battery, but no use in remote areas unless you take a genset with you, which also needs fuel).

Based on 2019 figures to avoid Covid distortions:

  • 68m tons total oil use in UK
  • 12m aviation
  • 36m road transport
  • 9m tons to industry, domestic, agriculture, commercial
  • 7m tons non-energy uses - I assume plastics, chemicals etc
  • 4m tons for refining

HGVs and buses take ~7-8m tons of the road transport - the balance is cars.

If the combined requirement for fuel is (say) 50m tons (road + air + agriculture), EVs will reduce oil demand by ~55% (28m tons). Industry, chemicals, plastics etc will not change.

Hydrogen may replace the remaining 45% of fuel users in time - although as batteries seem likely to get lighter and cheaper they will be fitted to an increasing number of freight vehicles.

Distribution logistics if/when driverless becomes a reality may change to favour smaller, lighter, electric vehicles and supplant HGVs - no driver constrained by tachograph!

I wonder if this will be used as the tech seems good and is easy to enough for most to change themselves This BANNED Technology Could Push Hydrogen Cars Over BEVs - YouTube

I noticed this some time ago but its improved since then and maybe we will see it in new cars
