US picks the first two sites for carbon-capture hubs
Up to $1.2 billion in funding for handling \"legacy\" carbon emissions.

That\'s crazy in so many ways.
The two pilot projects (capturing 0.002 Gt annually) can not matter to US currentOn Tuesday, August 15, 2023 at 2:12:37â¯PM UTC+10, John Larkin wrote:

Not as crazy as continuing to burn fossil carbon as fuel when we know it is wrecking the climate.
Tapering off is less painful than going cold turkey - the withdrawal symptoms would include a lot of deaths - but we really should be tapering off faster.
John Larkin has been brainwashed into thinking that more CO2 in the air isn\'t damaging the climate, but that\'s mostly because he doesn\'t have a lot of brain to wash.

\"The ultimate goal is to cut the cost of capturing and storing a tonne of CO2 below $100 before a decade has expired.\" As James Hansen has pointed out on the basis of atomic weight argument, $100/t CO2 is really $400/t C. So it\'s really a quite bit more expensive than they mislead people to believe.
\"The former Office of Fossil Energy has been renamed to Fossil Energy and Carbon Management as part of this focus.\"- OMG! Another institutional reorganization, that\'s always used to deflect previous failures.
\" The DOE estimates that will be the equivalent of taking roughly half a million cars off the road.\"- probably an gross overestimate, and even then, not much for a place like this:
\"There are 290.8 million cars in the U.S. as of September 2022. This number includes all vehicles, including cars, SUVs, vans, and other medium- and heavy-duty vehicles that were registered. Between 2021 and 2022, the number of cars in the U.S. rose by 0.45%\"
Until society very seriously and drastically curtails GHG emissions, DAC will never keep up, since legacy CO2 is ever growing. Notice they use the word \'legacy\' to imply something from the past that\'s no longer ongoing, and that\'s certainly untrue.

People pretend that there is a giant plastic bubble over the USA or
over Berkeley CA, and that our cutting back on CO2 will improve our
climate. There is no bubble.
China and India are building coal plants weekly, and Australia and
Indonesia and Russia are happy to sell them gigatons of coal.

China may be building more high efficiency (about 30%) coal-fired power plants, but it is retired lots of older low-efficiency (about 8%) plants. That\'s actually reducing their CO2 output per kW.hour generated
Where did you get such low efficiency numbers ?
The Carnot efficiency defines the power plant efficiency. The larger
the temperature difference between the hot and cold side, the higher
the efficiency.
Current nuclear reactors do not tolerate very high temperatures, thus
limiting the efficiency just above 30 %, the EPR runs up to 37%.
However coal-fired power plants tolerate at temperatures of 550 C so
efficiencies well over 40 % is possible.
