Bill Gates backed Canadian scientist seek to remove CO2 from airNaija247news

"This is a real step forward, and it's not just our company saying it", Prof David Keith from Harvard University, and a founder of Carbon Engineering told BBC News.

If Keith's company can live up to promises laid out in the new Harvard study it would leapfrog Climeworks, a Swiss company that has already launched a commercial-scale plant that can use its own DAC process for around $600 a metric ton.

The startup uses Carbon Engineering (CE), which are banks of fans that get air to capture carbon dioxide.

"At Carbon Engineering, we now have the data and engineering to prove that DAC can achieve costs below $100 (U.S.)", he said.

Noah Deich, Executive Director, Center for Carbon Removal, says: "Direct air capture technology offers a highly-scalable pathway to removing carbon from the atmosphere". 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. Still, Field cautions that the technology isn't a silver bullet for combatting climate change-there's no way yet to know whether it can scale up quickly enough to alter Carbon dioxide levels in the atmosphere.

"We've bought the smallest scalable unit of each piece of technology we have". And a spokesman for the firm said it can readily scale up using off-the-rack hardware, The downside is that the plant is now using some natural gas for power, but the goal is to switch to renewable electricity. "So we hope it is really a turning point". The problem has been finding a way to drop costs and then make it work on a large scale.

While scientists have endeavoured to come up with numerous methods for removing CO2, by far and away the most effective process is Direct Air Capture (DAC). In the fuel cases, the carbon is essentially recycled and replaces fossil fuels pulled from the ground, hence the process is carbon neutral.

Prince George stole the show at Trooping the Colour on Saturday afternoon, but his baby brother appeared to be missing in action. George, who turns five in July , was just as excited as he watched the roaring fly-past by the Royal Air Force.

Canada's Carbon Engineering claims CO2 could be sequestered from the air for less than $100 a ton and converted into carbon-neutral fuel for existing vehicles.

Not only are the scientists sucking Carbon dioxide out of the air, but they are also commercializing a process which uses water electrolysis and fuels synthesis to produce clean liquid hydrocarbon fuels that are drop-in compatible with existing transportation infrastructure.

Carbon Engineering is building a larger plant, utilizing low-priced renewable energy, that will produce 200 barrels of synthetic fuel a day. That's because the new study bases its numbers on data and costs from a real pilot facility, whereas others have relied on scientists' best guesses of how Carbon dioxide capture technologies scale up.

Carbon Engineering, which has about 40 employees and produces about a tonne of carbon dioxide a day from an experimental plant. "We are not going to run out of air anytime soon", adds Steve Oldham, CEO of Carbon Engineering.

However, plans to capture Carbon dioxide directly from the air have been regarded as somewhat more substantial - essentially mirroring the actions of trees.

There are plenty of hurdles to overcome before we can see any benefit from this technology. The market will get a further boost as the Canadian government and US states adopt clean fuel standards that will provide incentives for marketers to purchase low-carbon alternatives.

Keith said the establishment of an industrial-scale production plant to absorb air could produce fuel at United States dollars 1 per liter.
