How do you make air travel greener? This Rolls-Royce pledge is a big part of the answer
The hunt is on for ways to make air travel less carbon-intensive, especially with demand set to soar as countries emerge from the worst of the pandemic. An announcement on Thursday by Rolls-Royce is a big step in the right direction...
Rolls has previously said that sustainable aviation fuel, which is produced from feed stocks such as cooking oil, non-palm waste oils from animals or plants and solid waste from homes and businesses, offers "net CO2 lifecycle emissions of at least 75% less than conventional jet fuel".
Sounds good but we clearly need to make sure green feed stocks are adequate. Cooking oil is an obvious area we could easily boost via a number of measures.
- Green subsidies for fish and chip shops.
- Replace BBC presenters with much more rotund folk.
- Develop BBC food programmes such as the Great Green Fry Up.
- Introduce a Green BMI of 30 to make people less anxious about their weight.
- School meals could have Green Fry Up Day every week.

Now if they could find a use for ascetic acid for cleaning the engines or de-icing then the smell at airports would be irresistable.
Amazon were going to market an idea called the "Flying Pan", but called it off after complaints from the Chinese.
Sam, 'Go wok, go brok'...
o/t slightly, but Coldplay are hoping to power some of their concerts by use of a kinetic floor, which creates energy by the croud jumping up and down!
Now that would save all those steak tenderisers being powered up, the kids could just leap up and down on all the meat that apparently isn't used here any more...
From the interwebs:
"The global fuel consumption by commercial airlines increased each year since 2009 and reached an all-time high of 95 billion gallons in 2019."
Plus talking of rapeseed oil 'expectations':
"The £1bn fish and chips industry uses about 100,000t of oil a year, and Mr Marriott hopes the new product will make big inroads into this market and also the wider food service area."
and
"Global biodiesel production reached 3.8 million tons in 2005"
Not enough to fuel a fleet.
Since fish and chip oil and ordinary biodiesel would have to be processed to make aviation fuel then there is some way to go...
Sackers - pie and peas for me - wi' proper gravy.
Doonhamer - I once followed a bus supposedly running on fuel made from old cooking oil. May have been my imagination but the exhaust aroma was quite pleasant.
Sam - and now they have probably made one.
Scrobs - surely treadmills would be better.
DJ - Rolls Royce probably expects a phased introduction beginning with a few percent as for alcohol in petrol. What they expect in the long term would be interesting to know.
