This ‘essential’ expense would likely go the way of HS2 and double or triple in real cost, with at least some costs continuing well after the target date. Absurd is too weak a word to describe this fear of a harmless trace gas essential to nature. CO2 is not pollution.

Britain must invest [sic] £30bn in a network of massive air cleansing systems designed to strip CO2 from the atmosphere if it is to reach net zero, a government-funded report has warned.
The “direct air carbon capture systems” would remove up to 48 million tonnes of CO2 from the air each year and then pump it into disused oil and gas reservoirs under the North Sea or Irish Sea, says The Telegraph.
Without such a scheme the UK will never reach its target of net zero emissions by 2050, according to the report by Energy Systems Catapult, a government-funded body that promotes innovation.
It also warns that direct capture will be essential if the UK is to maintain an aviation industry, because aircraft are unlikely ever to run entirely on sustainable fuels.
“Beyond 2040 we see few options to abate remaining emissions so use of direct air carbon capture and storage (DACCS) will be required,” it said.
“Direct air capture would collect 38-48 million tonnes of CO2 a year by 2050. This technology appears to be essential to meeting net zero in all our scenarios and yet remains unproven at scale.”
Direct air capture plants would need to be built along the UK’s east coast, from East Anglia to Aberdeen, so that the CO2 captured could be pumped to storage sites under the North Sea, the study said.

The Department for Energy Security and Net Zero is already spending £100m of taxpayers money on experimental projects to capture CO2 from the air, with plans to turn any successful ones [Talkshop comment – none so far?] into full-scale industries by 2040.

The Department for Energy Security and Net Zero is another stupid government department that need removing and its members sacking and a note made on their file that they should never be employed again – no revolving door for them.
I think it is about time that the government employed real scientists, not the ideological pseudo scientists that the education system is producing now.
“So Called” Scientists are educated in institutions that require strict compliance with alarmist dogma. Those who question, as science is supposed to do, do not graduate and get the “credentials” to be a scientist.
Intelligent people who have knowledge that was acquired outside of the strictly enforced Consensus Climate Science Dogma must step forward and help correct the theory that one trace gas controls climate change.
Two words – Henry’s Law.
Absolutely! There’s over 50 times more CO2 disolved in the oceans, ready to replace the £30b worth of CO2 removed by our hapless politicians.
