00:00What if I told you that this Swiss airplane is flying on fuel made from literally nothing but
00:04air and sunlight, not biofuel, not hydrogen. Actual jet fuel, chemically identical to what
00:12powers every commercial flight, but created by pulling CO2 directly from the atmosphere.
00:18This isn't science fiction. This happened in 2025, and it's just the beginning of a revolution that
00:23could change aviation forever. Aviation accounts for about 3% of global CO2 emissions, but
00:29here's the problem. You can't exactly put a battery in a Boeing 777 for a 15-hour flight to
00:36Singapore. The energy density just isn't there yet. So while cars are going electric and ships
00:42might run on hydrogen, aviation needs liquid fuel. The question is, can we make that fuel without
00:48drilling it out of the ground? The answer is increasingly yes, and it's happening faster
00:54than most people realize. Here's how you turn air into jet fuel. First, you need a direct air
01:01capture facility, essentially a massive vacuum cleaner for CO2. The largest operational one right
01:08now is Climework's Mammoth facility in Iceland, which can capture 36,000 tons of CO2 per year.
01:15Next, you split water into hydrogen and oxygen using renewable electricity. This green hydrogen is
01:23crucial. If you're using coal power, you're defeating the whole purpose. Then comes the
01:28chemistry magic. You combine that captured CO2 with green hydrogen through a process called
01:35Fischer-Tropsch synthesis, or newer one-step processes, to create synthetic hydrocarbons.
01:42Finally, you refine these hydrocarbons to meet ASTM D7566 standards, the same specification as
01:50conventional jet fuel. The result is drop-in compatible fuel that works in any existing
01:56airplane engine. So who's making this happen? Let's start with 12, formerly called Opus 12.
02:05They've created something called E-Jet, synthetic aviation fuel that's already ASTM certified and
02:11flying with United Airlines and the US Air Force. Then there's Infinium, building what they call
02:17Project Roadrunner in Texas, planned to be the world's largest e-fuels facility when it comes online.
02:24Syngelion took a different approach entirely. Instead of using electricity, they use concentrated
02:30solar heat to drive the chemical reactions. They just delivered the world's first solar-made jet fuel to
02:36Swiss International Airlines in 2025. And HIF Global in Chile is producing E-Gasoline and E-Kerosene at
02:45their Haruoni facility, with backing from Porsche and Shell. But let's talk money. Because this isn't cheap.
02:52Right now, direct air capture costs somewhere between $600 and $1,000 per tonne of CO2. The companies say they
03:01can get that down to $100-$250 per tonne at scale, but we're not there yet. And the energy requirements
03:07are massive. It takes about 20 to 30 kilowatt hours of electricity to produce one liter of synthetic jet fuel.
03:15That's enough electricity to power an average home for about a day, just for one liter. This means E-fuels
03:21currently cost around €3 per liter or more, compared to about €0.50 for conventional jet fuel.
03:28Without subsidies, airlines simply can't afford this. But here's where politics comes in to change the
03:35game. The European Union's Refuel EU Aviation Mandate requires airlines to use 2% sustainable
03:43aviation fuel starting in 2025, ramping up to 35% by 2050. More importantly, there's a specific sub-target for
03:52E-kerosene, at least 1.2% by 2030, jumping to 35% by 2050. This creates guaranteed demand regardless of cost.
04:03In the United States, two tax credits are making the economics work. The 45Q credit gives up to $180
04:10per tonne for captured CO2, and the new 45Z Clean Fuel Credit can provide up to $1.75 per gallon for
04:19sustainable aviation fuel. These subsidies are essentially bridging the cost gap until the
04:25technology reaches commercial viability. But scaling this technology isn't easy.
04:31Climework's Mammoth facility has faced operational challenges in 2025,
04:36performing below its nameplate capacity and requiring workforce adjustments.
04:41The next major test comes from Occidental's Stratos facility in Texas, designed to capture 500,000
04:48tons of CO2 per year, more than 10 times larger than Mammoth. If Stratos works as planned when it comes
04:55online at the end of 2025, it could prove that DAC can reach industrial scale. There's also the
05:01fundamental question of energy competition. Every kilowatt hour used to make E-fuels is a kilowatt hour that
05:09can't electrify ground transport, heat buildings, or power industry. We need massive renewable energy
05:16expansion to make this work without tradeoffs. Let's be honest about the climate impact. E-fuels
05:22are only as clean as the electricity used to make them. If you're using grid power that's still partly
05:28fossil-fueled, your sustainable aviation fuel might not be that sustainable. And E-fuels only address CO2
05:36emissions. They don't solve aviation's other climate impacts like contrails and high-altitude nitrogen
05:42oxides, which some scientists estimate could be as significant as the CO2. The real question is whether
05:50massive investment in E-fuels is the best path forward, or whether that money and renewable energy
05:56would have bigger climate impact elsewhere. Looking ahead to 2030, the industry needs to scale from today's
06:03small pilot projects to hundreds of thousands of tons of production annually to meet those EU targets.
06:11Projects like Norsk E-fuel in Norway, planning 50 million liters per year, and multiple facilities
06:17from Infinium could make this possible. But most are still in development phases,
06:23with major technical and financial risks ahead. The companies say they can reach cost parity with
06:29conventional jet fuel by 2030-2035, but that depends on continued technology improvements, cheap renewable
06:37electricity, and sustained policy support. So, can we really power aviation with fuel made from air?
06:44The technology exists, and it's working today, but at tiny scale and high cost. The next five years
06:51will determine whether this becomes a niche solution for premium routes or a mainstream technology that
06:57could decarbonize flying. What do you think? Will E-fuels made from air become the future of aviation?
07:05Or are we better off focusing on other solutions like hydrogen, or even accepting that flying needs
07:10to become more expensive and less frequent? Let me know in the comments. And if you want to dive deeper
07:16into the companies and technologies making this happen, I've linked all my sources in the description below.
