Can sustainable aviation fuel clean up flying? | FT Rethink

Proposed plan for Boeing: start by keeping your aircraft in the air; Next move to biofuel.

[@JetPro11]

Thousands of Boeing airplanes do tens of thousands of flights everyday…safely. I challenge you to find anything mode of transport safer than that.

[@lours6993]

@@JetPro11 If they fly safely, it is in spite of and not due to, corporate values. Fix that.

@6:45 - "It will be a challenge, we have had the industrial revolution that took place over 100 years that needs to be done again in the next 10 years. That is a heavy lift, as a human race, we have done it before so i think we can do it again"

[@jaslarja]

SAF as E-fuel is the only way. Stop that biofuel thing lol

[@user-pt1ow8hx5l]

Ammonia is more promising. And cheaper. Yet, as they say in the video, it's a little longer way of.

[@Sacto1654]

Sustainable Aviation Fuel (SAF) from oil-laden algae has been researched for quite a long time. That's the biomass source that will be used for this fuel, mostly because oil-lagen algae has the potential to be made on a true large scale worldwide.

just as hair grease.

your wrong on this one bud

[@zapfanzapfan]

I wouldn't count fuels made from palm oil as anything near eco friendly...

[@denyoellamcy8251]

Its much more ecofriendly than normal jet fuels..It reduces carbon emissions by 80%

Most plastic is petroleum derived, however most of the plastic waste is being burned or buried anyway (due to high cost of recycling and limited recyclability of plastic). Even if certain plastics like PVC and CPVC had to be filtered out, this requires far less sorting (and cost) than conventional plastic recycling. Fortunately, it turns out that plastic can be easily converted into jet fuel in a single step! It requires only a simple heating process, no FT synthesis required! This is inexpensive and scalable. As a bridge solution it could help lower the high cost of an SAF blend while also addressing the problem of plastic waste piling up. The quantity of plastic waste in the U.S. is 1.3 lbs/person/day, (0.6 kg/person/day), a similar weight to the consumption of jet fuel (1.3 lbs/person/day). If all the currently non-recycled plastic were converted, it could in theory supply up to 1/3 to 1/2 of the total jet fuel use.

There is a small comment one should put; palm oil does not come from Brazil to start... What is the main barrier, for palm based from Asia or soy based from Brazil/Argentina or cooking oil from elsewhere, is that this is not environmentally 100% green. For many arguments the push back remains not the net-saving for the environment but the incomplete "green" solution. In the end this is an imperfect solution with great saving potential for energy consumption for airlines, marine transportation and road fuels. In regards to agricultural yield per hectare of palm oil farming, please show which is yielding better.

[@calado2000]

Correct me if im wrong. Its claimed ethanol is from plants that captured co2. But oil comes from plants too (millions years ago) that captured co2. So ethanol polutes the same as oil?

[@michaelmiklosofficial]

Bio fuel and hydrogen is the way forward

Aircrafts and Trains compete with similar fares on majority of short routes. But trains are electric. So the aviation industry has a dirty advantage of using cheap fossil fuels. There for I hope there will be regulation to curb this aviation pollution to force them go green. At least for domestic routes.

[@BillobanBilloba]

the sky was blue because there was water in it. the sky is no longer blue because the remnants of airplane flights disturb the particulate nature of the formation of raindrops. that's why your head will be dry, the rain will not fall, and the sky will be white, 90% of the days of the year .that will of course also affect the wind, the temperature rise above the ground, the biosphere, etc. if by chance plane flights were to be suspended, blue days, blue skies would instantly appear..like before..peace

What a grab bag of pseudo science!

E Kerosene is the next jet fuel.

"But aviation is just 3% of emissions": Only because most people never fly. It's a huge emission % for those privileged few who do fly. With reduced poverty, aviation is expected to grow massively, faster than can be offset by slowly reducing emissions per flight. "But population growth": The populations that grow quickly have low consumption. High consuming populations grow slowly, or decline. Impact = consumption times population. High consumers have orders of magnitude higher emissions per person, and don't get a guilt free pass to point fingers at poor people with many babies. With great power/wealth comes great responsibility. More money = more choice. SAF seems on the whole less bad than the status quo, but will still have big negative impacts, as the video shows. Stopping aviation growth is still good, SAF or no SAF. We should all think carefully about what consumption we can justify. I'm flight free for 5-6 years now, I don't miss flying and I love trains, but I consume other things of course, like computer gear and youtube. I won't criticise those who have close family outside of train range and fly to meet them. But most of us can quite easily choose not to fly. And vote for greener politics.

[@markdavis8888]

People fly too much and eat too much beef.

[@unclefurbiesvoice9902]

There's a very simple way to improve emissions from aviation flights. 1st and foremost: Stop the flights, or reduce by 97%+. Problems solved.

[@thesoaringdutchman]

The KLM guy has such a heavy Dutch accent, I always feel ashamed when someone with such an accent gets picked to represent my country. I just can't take it seriously

[@lours6993]

Don’t worry. It’s intelligible. Nobody really cares.

[@joefulton8011]

The claim that 100% of airlines are able to be fuelled using SAF... yet what about the emissions for the production that goes into the airplanes being built? It would be huge (as it is already!) so how far down the line will they breakeven? We have already seen how expensive air travel was when commodity prices were at the all time highs a few months ago... Sustainable Aviation Fuel needs to maintain a blend!

It's not that meaningful in long term. Commercial aircraft usually fly 20-30 years. Most of their monetary and ecological cost comes from actual use, fuel, not from the initial manufacturing cost. For example in passenger cars, that have perhaps 15 years of life on average and are used perhaps 2-3h daily on average have only 1/3 of the cost in manufacturing. Commercial aircraft are used 12-14h on average in a day and have perhaps 25 years of life. The cost of manufacturing is perhaps 1/15 or 1/20 of the total cost during the lifespan.

[@PDZ1122]

If you're concerned about what fuel airliners use - Don't fly! And stop whinging.

And Airbus are going with hydrogen which is a much better solution for short trips.

[@matthewbaynham6286]

@ericliu5491 many people like to fly and they will fly.

[@saullotzof]

Narrator is atrocious. Please get someone new. Also sound in general is quite poor.

[@beezer370]

The sound reminds me of a toilet flushing repeatedly.
