vastaan, jota edellä sanoin tai annoin muiden sanoa:
To help with climate change, carbon capture will have to evolveGovernments and industry are betting big on such projects. [In 2023], for example, the British government announced £20 billion (more than $25 billion) in funding for CCUS, often shortened to CCS. The United States allocated more than $5 billion between 2011 and 2023 and committed an additional $8.2 billion from 2022 to 2026. Globally, public funding for CCUS projects rose to $20 billion in 2023, according to the International Energy Agency (IEA), which works with countries around the world to forge energy policy.
Given the urgency of the situation, many people argue that CCUS is necessary to move society toward climate goals. But critics don’t see the technology, in its current form, shifting the world away from oil and gas: In a lot of cases, they point out, the captured CO2 is used to extract more fossil fuels in a process known as enhanced oil recovery. They contend that other existing solutions such as renewable energy offer deeper and quicker CO2 emissions cuts. “It’s better not to emit in the first place,” says Grant Hauber, an energy finance adviser at the Institute for Energy Economics and Financial Analysis, a nonpartisan organization in Lakewood, Ohio.
Tai ehkei aivan. Tällaisia vastaväitteitä sille löytyy:
What’s more, fossil fuel companies provide funds to universities and researchers — which some say could shape what is studied and what is not, even if the work of individual scientists is legitimate. For these reasons, some critics say CCUS shouldn’t be pursued at all.
“Carbon capture and storage essentially perpetuates fossil fuel reliance. It’s a distraction and a delay tactic,” says Jennie Stephens, a climate justice researcher at Northeastern University in Boston. She adds that there is little focus on understanding the psychological, social, economic and political barriers that prevent communities from shifting away from fossil fuels and forging solutions to those obstacles.
According to the Global CCS Institute, an industry-led think tank headquartered in Melbourne, Australia, of the 41 commercial projects operational as of July 2023, most were part of efforts that produce, extract or burn fossil fuels, such as coal- and gas-fired power plants. That’s true of the Sleipner project, run by the energy company Equinor. It’s the case, too, with the world’s largest CCUS facility, operated by ExxonMobil in Wyoming, in the United States, which also captures CO2 as part of the production of methane.

Current and future projects are unlikely to capture carbon in sufficient quantities to make much of a dent [in] global emissions, O’Leary says. Estimates suggest that existing projects could capture around 50 million tons of CO2 annually — cutting the more than 35 billion tons of gross global carbon emissions by around 0.14 percent. Once all 392 projects are online, they could capture a few hundred million tons — about 1 percent of carbon emissions. Estimates of how much carbon CCUS needs to capture to help achieve climate goals vary widely between 1 billion and 30 billion tons annually by 2050.
Niinpä kirjoitusta kokonaisuutena voinee luonnehtia niin, että siinä ollaan vielä odottavalla kannalla.
