Hi,

I´ve got the feeling we have to go back to the diesel to run around in. Here in Spain we've got the ECOdiesel that's made of a 100% renewable energy.
Made of waste and CO2. We can fill up in Repsol Stations. And for now, I haven't noticed any difference, OK, it's about 10% more expensinve, but I think it's a price we can pay.
If anyone wants to know a bit more, I'll leave a link,

And maybe you don't have to buy that EV after all

More expensive than regular diesel

Not zero-emission: Cars still emit NOx/particulates, so from an air-quality perspective, EVs remain cleaner.

You don’t have to buy an EV anyway!

Running on the likes of waste cooking oil has been around for many years. It's a renewable and as yet no car can be said emmet Zero CO2 (end to end energy production cycle) seams a good pathway to Net Zero until ICE is banned.

We're rapidly running out of Diesels cars to put this into in the UK though... On current trajectories, by 2031, there will be more EVs in the UK car fleet than Diesels. Fine for those that have a Diesel currently and want to hang onto it, but there won't be enough cars to go around. There's been a near 20% drop in Diesel cars on the road in the UK since their peak in 2018 and this decline is only accelerating. Over the last 12 months, over 1500 more Diesels disappeared from our roads every day, than were replaced.

Diesel Trucks on the other hand……

HVO emits circa 90% less CO2 compared to diesel. It’s a great step towards reducing emissions.

Don’t concentrate on CO2, there’s more to emissions than that.

The allowable emissions for a Euro 6 diesel car are:-

Carbon Monoxide (CO): 0.50 g/km
Hydrocarbons and Nitrogen Oxides (HC+NOx): 0.17 g/km
Nitrogen Oxides (NOx): 0.08 g/km
Particulate Matter (PM): 0.005 g/km


Home heating accounts for 38% of all UK gas use, and an average household gas boiler emits greenhouse gases equivalent to approximately 2.2 tonnes of CO2 per year.

A typical car can emit over 1,000kg (1 tonne) of CO2 annually based on average mileage and emissions

Who is this "we" you are referring to - the Royal We?!

How do they get this stuff to the petrol stations...?

Already happening…..

Demand is growing, availability expanding.

There's only so much used veg oil around.

There have been a few exposes about so-called 'waste' oil coming straight from the farm.

In America, they have high-bio-content petrol, using a lot of corn.
You need a lot more land to grow fuel for an IC vehicle than to power an EV with solar panels.

used to see people topping up their 205 diesel outside asda with the their own brand vegtable oil.
was way cheaper and no tax
no wonder the fuel companys and gov wanted it banned.scratchchin

And given the excess of unstorable solar power in Spain, using it to charge EV's would seem far more sensible than messing around with new types of diesel - which are still more expensive, damaging and st to drive.

If Spain has an excess of unstorable electricity why don't they sell it to the European grid or use it to charge EVs? Turning it into biodiesel seems like a circuitous and long-winded activity.

Anything involving producing fuel, transporting fuel, igniting fuel, is fundamentally wasteful compared to the electric alternative.

The OP has presented nothing new or remotely beneficial, other than for those people that absolutely love their diesel cars and are prepared to pay more for diesel fuel to make it mildly less damaging. It's still in no way an eco alternative to EV, not even close.

Under the Scope 1 GHG protocol it is the only measure.

But cars have been subject to emissions restrictions on many more fronts than Greenhouse Gases.
There is no great future for IC cars in developed cities.

Bio diesel probably has a role with HGVs, construction plant, back up generators and marine during some transition period or other.
