Ministers hope Turkish Airways will make its first biofuelled flight by the tip of 2022, however consultants are sceptical algae could make a lot of a dent in aviation emissions
A laboratory to develop algae for jet gas opened in Istanbul this month, as a part of an EU-backed push to chop carbon emissions from flying.
The €6m ($6.8m) demonstration challenge is funded by the European Union and Turkish authorities. It’ll develop easy water-based crops, often called algae, in outside ponds and indoor tubes, and refine them into gas and different merchandise.
After touring the positioning on Boğaziçi College’s campus and handing out algae-based candies to reporters, Turkish power and pure assets minister Mustafa Varank mentioned: “The work is underway for the usage of biofuels produced right here by Turkish Airways. We would like [them] to hold out [their] first flight utilizing biofuel from right here earlier than the tip of 2022.”
Consultants instructed Local weather House Information biofuel from algae had potential however expressed scepticism it could possibly be produced on a scale to interrupt aviation’s dependence on fossil fuels.

Dan Rutherford is the aviation director of the Worldwide Council on Clear Transportation. He mentioned: “Algae jet gas is type of like disco, [it] comes again each decade or so however in a worse kind. The US authorities has been selecting at this for no less than 30 years and has by no means figured it out.”
In 2011, a aircraft flew from Houston to Chicago powered by gas which was 40% algae-based and 60% petroleum. Solazyme, the San Francisco-based firm which developed the gas, filed for chapter in 2017.
Aviation is a notoriously troublesome sector to scrub up. Electrical batteries, the principle answer to land-based transport, are heavy and never highly effective sufficient to maintain planes within the sky for lengthy durations.
Biofuels comprised of crops like soy compete with forests and farms for land. As water-based crops, algae don’t pose that downside – however they nonetheless have points.
Named: The oil firms playing on local weather failure
The primary problem is competing on value. The value of conventional jet gas from petroleum has doubled previously yr to $830 a tonne. It’s nonetheless cheaper than sustainable alternate options, which a McKinsey evaluation in 2020 costed at $1,300-3,800/t, relying on the manufacturing methodology.
Berat Haznedaroglu, director of the Istanbul challenge, instructed Local weather House he was aiming to get the worth all the way down to $1,000/t for algae-derived gas. He expects curiosity in clear fuels to develop as governments, airways and airports attempt to meet their local weather commitments.
“There will probably be a mandate coming from [industry body] IATA and the governments,” he mentioned, including that the elevated value of utilizing clear fuels could be handed on to passengers. “I believe it’s going to be €10-15 ($11-17) per ticket”.
Brussels-based thinktank Transport and Surroundings’s aviation director Andrew Murphy mentioned: “EU funding in sustainable aviation gas (SAF) growth in Turkey is an efficient technique to convey that aviation market into the scope of its personal SAF measures reminiscent of ReFuelEU.”
However, he added: “Algae has some considerations as a consequence of scalability, so each the EU and Turkey have to fund feedstocks which could be extra simply expanded.” For instance, he proposed hydrogen derived fuels like e-kerosene.

Haznedaroglu mentioned that hydrogen-derived fuels had been “part of the toolbox” however that the majority hydrogen continues to be comprised of fossil fuels and “the analysis path for hydrogen continues to be somewhat behind algae”.
The Istanbul facility is a university-based demonstration challenge. It goals to show the idea, to not grow to be a large-scale provider itself.
One other limiting issue is the climate. A US power division examine discovered that algae manufacturing charges “range dramatically from summer season to winter, even in locations like Florida”. Istanbul has a median most each day air temperature in January of 9C (48F).
Haznedaroglu mentioned it might be preferable to develop algae in hotter southern Turkey, however there are cold-resistant types of algae which survived current snows in Istanbul. Algae grows in locations as chilly as Iceland.
The Istanbul facility will produce algae for meals dietary supplements, animal feed and fertilisers in addition to jet gas.
Rutherford mentioned: “That’s a recurring theme on biofuels typically for aviation. You begin off saying ‘jet gas’ and you then begin producing merchandise and lots of them are fairly fungible. They find yourself cosmetics, meals, changing petrochemicals.”
Haznedaroglu mentioned that 80 cubic metres of the positioning’s 110 cubic metres are devoted to biofuel manufacturing in outside ponds. The opposite 30 cubic metres are the indoor tubes.
These are dearer however much less more likely to be contaminated by air pollution. These are used for merchandise like meals dietary supplements the place avoiding contamination is especially vital.
