Canadian firm publishes details on Carbon dioxide to fuel pilot

"You can make gasoline or diesel fuel [via direct air capture] but, of course, they didn't come from the ground, so the amount of carbon they emit when they burn is just the amount you used making them, so they're carbon neutral", says Keith.

Making direct air capture as cheap as possible is critical because a growing body of work finds it's going to be almost impossible to prevent global temperatures from rising more than 1.5 ˚C without rolling out some form of the technology on a huge scale.

Researchers say they have developed a cost-efficient way to extract carbon dioxide from the air and make fuel from it for cars, trucks, or airplanes. "This is real", he said.

Other experts welcomed the study as a step to remove the severe uncertainty about the cost of gas collection technology directly from the atmosphere.

Instead, Trump acknowledged, the summit is unlikely to achieve a major breakthrough, stating that at minimum he would like to "start a dialogue" with Kim.

Carbon Engineering has issued a study proving that it is possible to capture carbon at a cost of $100 per tonne, which means a cost that is 6 times lower than the current cost of $600 per tonne. "This must change quickly if we are to fulfil the Paris agreement", she explained. Climate scientists say countries will need to drop Carbon dioxide emissions to near zero by midcentury and then remove more Carbon dioxide than they emit, if the planet is to avoid a catastrophic 2°C warming.

Its direct air capture technology uses large fans to blow air through a solution of potassium hydroxide. There are two plants in Kansas that capture Carbon dioxide and transfer it via pipeline to oil fields where the oil is produced and the Carbon dioxide is stored in the process.

That is well below past estimates of about $600 a tonne by the American Physical Society, said David Keith, a Harvard University physics professor and the founder of Carbon Engineering who led the research.

Keith is also a founder along with chief scientist of Carbon Engineering, which is a Canadian firm that has been developing this technology. After capturing the Carbon dioxide in solution, the plant transfers it into a solid, which when heated releases it in a pure gas stream. The APS had costs of 780 $/t-CO2-avoided and 550 $/t- CO2-captured, where the emission from electricity supply outside the plant boundary.

Keith and Oldham are optimistic that they have reduced scale-up risks by implementing direct air capture at reasonable costs using standard industrial equipment.

The projected costs of direct air capture range from less than $100 per tonne when it is part of a fuels plant, to $250 per tonne when it used for pure sequestration that requires compression of the gas and additional capital costs for a stand-alone operation, concluded the paper which was published in the journal, Joule.

Direct air capture is pretty much what it sounds like: a large fan draws in lots of air and essentially filters it through a liquid solution which captures any Carbon dioxide it comes in contact with. The company is now making around one barrel a day by combining the pure Carbon dioxide with hydrogen derived from water, using renewable energy. Then it's prepped for other uses by heating and other chemical reactions.

Previous research and studies into direct air capture (DAC) have suggested that removing a ton of Carbon dioxide from the atmosphere would cost US$600, which is too expensive to be a feasible solution, Keith said. The resulting fuel could be made at a relatively low cost of just USD$1 per litre. That could drive a market for DAC plants that would likely drive costs down further, Oldham says.

LeBron James scored 33 points and Kevin Love added 20 for the Cavs . "We're just going to focus on what we can do to win Game 3". Warriors coach Steve Kerr is glad to have a familiar situation for his team in the road challenge. "I agree with LeBron ".

Global investors have funded a startup based in Squamish which created a revolutionary technology that could combat climate change in the future. "There is a long way to go to see whether it will have any large-scale impact".
