Carbon Capture Will Be Difficult & Very Expensive, Says UK Scientists

Coal mining is an idea that is attracting a lot of attention from climate scientists and a lot of research money from governments. For example, the British government is currently spending around $ 90 million to fund a competition to find the best ways to remove greenhouse gases from the atmosphere.

According to The Guardian, these technologies should start removing vast amounts of carbon dioxide from the atmosphere by 2030. The hope is that the winning methods could be expanded and ready for market in two years. The British government is confident that this will be the case. The Department of Transport has stated, for example, that greenhouse gas (GGR) removal technologies will enable the British to make “innocent flights” before the end of next year.

However at a Hub Greenhouse Gas Disposal event in London this week, organizers asked attendees if they believed the carbon removal targets would be met. Of the 114 who voted, 57% said they were “not sure” that Britain’s net zero by 2030 would be met, 25% said they were fairly certain, and 11% said there was no chance that let that happen. [A quick poll of the people at the CleanTechnica Tiki bar next to our rooftop lap pool found 100% of them believed that much ballyhooed goal was so not happening.]

A recent government press release announced somewhat breathlessly that these technologies will enable net zero flights by 2023. Professor Mark Taylor, deputy director of energy innovation at the Department of Trade, Energy and Industrial Strategy, said The Guardian, “No, that’s not the case.” He said the government’s position was “somewhat impertinent”. The techniques under consideration include direct air capture, biofuels, biofuel, afforestation and enhanced weathering.

Carbon Capture Is Hard And Expensive

One of the most popular approaches is direct carbon sequestration, a process that sucks carbon dioxide from the air and uses it to make stones or as a raw material for biofuels. It can also be pumped underground into abandoned oil and gas wells. Taylor says, “We need to use energy to extract the CO2, the net CO2 flow from the solid, so what we’re looking for is integration that can reduce the costs of DCC, and especially reduce the cost of CO2 extraction. And the energy costs of extraction. “It’s currently useless to capture CO2 from the air and then use natural gas to power a heat process to extract clean CO2.”

Taylor adds, “People see it as having the biggest market. It’s funding from American companies – it feels like a silver bullet, there are a lot of people who like it. Ministers like it because they think, ‘Oh, that sounds easy, you can take it out of the air and that’s it. ‘ And that’s the thing that gets invested. I really care if it’s the best solution. It’s very, very expensive. So some of the other technologies may appear to be winners, but the good thing about our competition is that we choose the best. “

Making fuel from crops means diverting food from people so that people can drive sports vans and trucks. In addition, thanks to heavy rains, punishing heat, prolonged drought and war in Ukraine, the risk of famine is particularly high this year. The same goes for reforestation, which seems like a wonderful idea in addition to taking land out of production as well as for growing food.

Enhanced weathering involves dropping tiny rock particles into the ocean to create chemical reactions that lock carbon into seawater. While it has potential, it is at an earlier stage than many of the other carbon sequestration methods. It may be able to compensate for ocean acidification but its overall impact on the oceans is still poorly understood.

Storing carbon in the soil is another popular method. But Gideon Henderson, chief scientist in the Department of Environment, Food and Rural Affairs, says The Guardian“There are concerns about how long carbon can be stored and how it is measured. If the soil starts to release carbon again soon after it is stored, it could cause problems, especially if it is not measured effectively and counted in net zero targets. .

“I think if we see significant financial resources coming into this area to encourage storage of ground carbon without being able to measure it, and be sure of its consistency, there is a risk of continued leakage from storage that is not constant or well enough measured. “GGR is difficult and expensive. And we can’t afford to see it as a substitute for offsetting sustainable emissions in sectors that can be decarbonised. There’s no excuse not to decarbonise, so we need to reduce emissions anyway.”

That’s the point

The point of all this is that the removal of greenhouse gas is being touted by politicians as a way to alleviate the worries people have about a warming planet. It is a a ploy promoted by the oil, gas, and coal companies. Tell people not to worry. We can do what we’ve always done – burn every molecule of fossil fuel we can find anywhere on Earth, whether in the Arctic, under the ocean, or on the highest mountains, because we can always pick it up. from Earth. atmosphere in the future.

So go back to sleep, people. Nothing to see here, go ahead. Nothing to see here, go ahead. Just keep buying all those huge cars and trucks as if they won’t be there tomorrow and let’s take care of the consequences. Nothing bad will happen because of course we have the best interests of humanity at heart and we have never lied to you, right?

Well, actually, they were lying to us for more than half a century and they are lying to us now and will continue to lie to us in the future so that they can keep their shareholders at peace and their senior management well fed. If you think that coal mining or any of these other strategies will cool the Earth as we continue to release carbon emissions into the atmosphere at an ever-increasing rate, we have some land in the Bermuda Triangle that we can let you have at a really good price. !
