As transportation sectors like transport and aviation stay difficult to decarbonize, a French startup claims to have developed a promising answer to cut back carbon emissions in these industries. Aerleum, based in 2023, says its know-how can pull carbon dioxide from the air and convert it into methanol, which can be utilized to gas cargo ships and function a base chemical in producing aviation gas.
The French utility firm Électricité de France just lately awared Aerleum the EDF Pulse Award within the carbon capture class for this innovation, which can assist offset a number of the emissions from transportation sectors that depend upon liquid fuels. Since 2019, EDF’s innovation accelerator, Blue Lab, has introduced the awards to spotlight the efforts of start-ups, innovators and entrepreneurs with new concepts that might transfer the power sector in direction of net-zero carbon emissions.
Aerleum’s proprietary reactor, which mixes CO2 seize and conversion in a single gadget, makes use of a sponge-like materials that may adsorb CO2 concentrations as excessive as 15 %, making it efficient for each direct air seize and level supply carbon seize, wherein CO2 is captured immediately from industrial exhausts. In direct air seize, CO2 makes up roughly 0.04 % of the gasoline being filtered; for level supply seize; that rises to 10 % for one thing like a pure gasoline energy plant smokestack. Aerleum’s founders say their system may very well be a great complement to such industrial services by filtering and changing CO2 out of the exhaust earlier than it reaches the ambiance.
Aerleum CEO Sebastien Fiedorow says that it takes about one hour for the proprietary sponge-like materials the corporate developed to tug in as a lot carbon dioxide as it could maintain. “The second stage, the conversion to methanol, is accomplished in about 20 minutes,” says Fiedorow. After that, the reactor begins one other cycle of adsorbing CO2 from the air. How a lot CO2 is captured and the way a lot methanol is produced, says Fiedorow, will depend upon the dimensions of the reactor.
“Carbon seize is dear,” says David Sholl, the director of the Transformational Decarbonization Initiative at Oak Ridge National Laboratory in Tennesse. “Since you’re attempting to both mitigate or offset some emission, the final word financial query is how a lot will folks pay to do that.” Oak Ridge employs a liquid solvent for CO2 absorption in a 3D-printed carbon seize gadget they developed to carry out direct air seize. Whether or not the mechanism is a sponge like Aerleum or a solvent like Oak Ridge, the query of value stays.
Aerleum’s method addresses the highest financial challenges going through carbon seize and conversion. Sholl factors out that changing CO2 economically is hard. CO2 is chemically nonreactive, making conversion each advanced and costly. However Aerleum says its reactor depends on a simplified course of that eliminates energy-intensive steps that might maintain the associated fee prohibitive.
Making Cash by Making Methanol
There’ll absolutely be a marketplace for all of the methanol Aerleum plans to supply. In line with the National Renewable Energy Lab in Golden, Colo., the U.S. authorities has set bold targets for sustainable aviation fuel manufacturing, with a objective to supply all aviation gas from renewable sources by 2050. Sholl says attaining this might require the manufacturing of tens of billions of liters of sustainable aviation gas every year. Scaling as much as that quantity in 25 years “is feasible,” he says. Aerleum CEO Sebastien Fiedorow says Aerleum’s know-how will play a giant function in reaching that objective.
Presently, most methanol is derived from fossil fuels like pure gasoline, with CO2 being a climate-changing byproduct. Aerleum’s renewable “E-methanol” course of might assist scale back or offset these emissions along with mitigating the CO2 output from different industrial processes.

The most important problem that Aerleum should resolve is that methanol created from skinny air is extra expensive than standard, fossil-fuel-based methanol. In line with a latest report from IDTechEx, a market analysis agency that makes a speciality of rising applied sciences, sustainable aviation gas is at present 10 instances as costly as standard jet gas.
Aerleum says it’s working to enhance its gas’s cost-competitiveness by economies of scale and using green hydrogen generated utilizing renewable sources equivalent to photo voltaic and wind. Its cost-cutting measures may also be aided by incentives from nationwide governments within the type of tax credit and aviation fuel production credits, like those america at present presents beneath the Inflation Reduction Act.
Others are betting that Aerleum can ramp up manufacturing, attain value parity, and ultimately flip a revenue. Enterprise capital companies 360 Capital and High-Tech Gründerfonds have invested large sums due to their perception that Aerleum has a successful components.
Aerleum is making an early entry to an business that Oak Ridge’s Sholl says could have complete annual revenues approaching US $100 billion if carbon capture-and-conversion targets are met. The startup introduced in October that it had raised $6 million to finance the development of a pilot-stage facility because it proceeds towards full industrialization. The output of the pilot-stage plant can be as a lot as 3 tonnes of methanol per thirty days or roughly 3,800 liters.
In line with Fiedorow, as soon as Aerleum overcomes the engineering challenges inherent in scaling up from the lab to the pilot stage, the startup can be on monitor for full industrialization of its capture-and-conversion course of. He says one other of the corporate’s objectives is to construct a first-of-its-kind manufacturing facility whose output can be about 300,000 tonnes of methanol—which equates to simply beneath 380 million liters—per yr by 2030. From there, he says, Aerleum will seemingly depend on licensing its know-how to massive industrial companies like oil and gasoline corporations which may afford to construct Aerleum-style reactors at their services to fulfill their greenhouse gasoline emission curtailment objectives.
Aerleum joins different innovators in carbon seize who’re attempting to make it scalable and inexpensive. Earlier this yr, Climeworks, a Zurich-based startup, launched new direct air capture technology designed to take away thousands and thousands of tonnes of CO2 yearly by the top of the last decade. In line with projections from the Intergovernmental Panel on Climate Change, the world might must seize between 6 billion and 16 billion tonnes of CO2 yearly by 2050 to mitigate climate change impacts.
If Aerleum’s know-how scales successfully, it might play a significant function in assembly these targets by decreasing emissions whereas additionally creating renewable gas for hard-to-decarbonize sectors like aviation and transport. In different phrases, Aerleum is actively working to rework a part of the issue into a part of the answer.
