Sorry. Shambling into my sunset years.

I've tried unsuccessfully to find an estimate of one obvious source: how much CO2 do the billions of folks on the planet expel in the breathes very year. I figured our resident experts might have a counter view. So far not any denial to the number but a comment on its significance.

This story has been updated.
The first large scale U.S. “clean coal” facility was declared operational Tuesday — by the large energy firm NRG Energy and JX Nippon Oil & Gas Exploration Corp.
Their Petra Nova project, not far outside of Houston, captured carbon dioxide from the process of coal combustion for the first time in September, and has now piped 100,000 tons of it from the plant to the West Ranch oil field 80 miles away, where the carbon dioxide is used to force additional oil from the ground. The companies say that the plant can capture over 90 percent of the carbon dioxide released from the equivalent of a 240 megawatt, or million watt, coal unit, which translates into 5,000 tons of carbon dioxide per day or over 1 million tons per year. They’re calling it “the world’s largest post-combustion carbon capture system.”
“There are not many coal plants that are being built these days,” said Mauricio Gutierrez, the president and CEO of NRG. “We think that actually having an experience in installing a [carbon capture and storage] technology in existing coal plants will have a pretty significant application in the current plants that exist throughout the country, and for that matter, throughout the world.”
But there is another coal plant near completion in the United States that will also capture carbon dioxide — but using a very different approach. It’s the Kemper Plant, being operated by Mississippi Power, a subsidiary of Southern Co., and expected to be operational Jan. 31. This plant has been designed to turn lignite, a type of coal, into a gas called syngas, stripping out some carbon dioxide in the process. The syngas is burned for electricity and the CO2 is then again shipped to an oil field to aid in additional oil recovery.
Thus, at Petra Nova the capturing of carbon occurs after the coal has been burned — or “post-combustion” — whereas at Kemper, it happens beforehand.
The arrival of Petra Nova and Kemper comes as the incoming Trump administration will have to try to deliver on sweeping promises made to the struggling coal industry. It remains unclear if that will involve any type of support for carbon capture technology or for the industry, but Trump did allude to “clean coal” while campaigning.
The two very different plants together mark the arrival of a technology, often called “CCS” for short, that has been heralded as essential to the future of coal burning in particular (though it has many other applications), but has struggled despite considerable subsidies from the U.S. Department of Energy. Several projects have seen their Energy Department funding withdrawn, but these two now stand at or near the finish line.
According to the Global CCS Institute, which tracks this fledgling industry, there are 21 carbon capture projects worldwide on a large scale that are either operating or have been built, but relatively few of these are in the power generation sector — making Petra Nova and Kemper quite novel in context of the United States. In Canada, the Boundary Dam Carbon Capture and Storage Project, also a “post-combustion” capture plant using coal, has been operational since 2014.
The Energy Department provided grants totaling $ 190 million to the Petra Nova facility, which cost $1 billion overall. Kemper is a considerably more expensive project, representing a $6.91 billion expenditure for a massive plant with a capacity of 582 megawatts. That includes $270 million in support from the Energy Department, also as part of its Clean Coal Power Initiative.
The Department hailed the news Tuesday. “As the world’s largest post-combustion carbon capture system, the Petra Nova project confirms that carbon capture and storage technologies can play a critical role in ensuring the nation’s energy security and providing good jobs for American workers, all while helping us reduce carbon emissions from coal-fired power plants,” said Christopher Smith, Assistant Secretary for Fossil Energy, in a statement.
For Petra Nova, a key part of the operation of the plant involves its pairing of power generation with oil recovery. Carbon dioxide injected into the oil field will increase its production, and with oil prices at $50 a barrel or higher, the plant is economical, according to NRG spokesman David Knox. Some of the carbon dioxide then remains sequestered in the oil field after the enhanced oil recovery process.
The plant’s completion is a milestone, says Gutierrez, and a doorway into a wider world of using carbon capture and storage. “I think in the future, this is a technology that is going to be necessary for gas units, as natural gas becomes this bridge fuel,” he said.
Furthermore, Gutierrez said, while the Petra Nova plant is paired with an oil field to help make it economical, that may not always be so with future projects. “We really chose the enhanced oil recovery to improve the economics of the plant to the extent that there is not a price on carbon,” he said. “Potentially that is not necessary to make the economics work.”
The company does not have any immediate plans to adapt a second coal plant with carbon capture technology, but Gutierrez said that if it wanted to do so, the know-how gained at Petra Nova would make the second plant cheaper.
The International Energy Agency and the United Nations Intergovernmental Panel on Climate Change have both said that carbon capture and storage will be a necessary technology to curb humanity’s greenhouse gas emissions.
“Any country that is in need to increase their power generation, and that is happening through fossil fuels, they will be looking at this technology as a way to mitigate the impact of carbon,” said Gutierrez.

The Department of Energy said last week the memorandum of understanding between the two countries would extend to carbon capture as well as methods such as chemical looping and oxy-combustion that make it easier to remove carbon dioxide from emissions.
"Together through the development of clean energy technologies," Perry said in a statement, "our two countries can lead the world in promoting economic growth and energy production in an environmentally responsible way."
Carbon capture and other technologies that seek to prevent carbon dioxide, a byproduct of burning fossil fuels, from entering the atmosphere are considered by analysts and industry officials as critical to the future of oil, gas and coal industries as countries around the world seek to slow climate change. Carbon dioxide is a greenhouse gas and a major contributor to global warming.
Earlier this year, at an international energy conference in Houston, the Saudi oil minister called on the industry to find ways to "minimize the carbon footprint of fossil fuels." Three major European oil companies, Statoil, Total and Royal Dutch Shell, meanwhile, are assembling a network of technology and facilities that will capture and store carbon dioxide released from industries in Norway, with a goal of expanding to other countries.
Despite such ambitions, carbon capture systems are few and far between. Even with some success stories - like NRG Energy's retrofitting of a Texas coal plant through the Petra Nova project - the costs remain high. The uses for captured carbon dioxide are limited to pumping it underground to increase oil production, and logistical and legal questions abound around storing it underground.
Petra Nova, installed at the W.A. Parish power plant in Fort Bend County, cost an estimated $1 billion. Each day, the system, which began operating about a year ago, can capture more than 5,000 tons of carbon dioxide, which is piped 80 miles away to an aging oil field. NRG has said it is unlikely to build another such project unless economics change to make it profitable.
The Obama administration awarded a $190 million grant to NRG to develop the Petra Nova project. But President Donald Trump has proposed cutting the program that funds the research and development of carbon capture systems by 50 percent.
Perry has suggested that he would like to put more money into carbon capture research. The technology also has support among some Democrats and Republicans in Congress, who believe that any hope of meeting the 2015 Paris accord's goal on climate change will require the development of carbon capture.

Carbon capture down on the farm could give Biden an opportunity
By now, everyone is experiencing the consequences of President Joe Biden’s war on fossil fuels. From horrendously high gasoline prices to the cost of cooling and heating homes and businesses, people are suffering the consequences of Biden’s Green New Deal enthusiasm. Of course, high energy prices are a significant cause of inflation. The production and transportation of goods and services require fossil fuels, for the most part. Food prices have been particularly inflated, as anyone who has been to the supermarket can attest.
Carbon capture has often been touted as an alternative to dealing with climate change that does not involve laying waste to the fossil fuels industry with the attendant misery inflicted on consumers. Whether it is developing power plants that capture carbon dioxide instead of belching it into the atmosphere or finding ways to suck carbon dioxide out of the air, such as by planting trees or through more exotic methods such as Project Vesta’s “green sand” approach , carbon capture holds a great deal of promise.
MIT Technology Review recently related another carbon capture project that recruits agriculture for the task of fighting climate change. A research group out of Berkeley, California, called the Innovative Genomics Institute is using a gene-editing tool called CRISPR to alter food plants to absorb more carbon dioxide, further decreasing the amount in the atmosphere. As a happy side effect, the researchers believe that the altered food crops would grow faster, thus increasing crop yields.
The institute's initial efforts will focus on rice, whose genome is well understood, as well as sorghum. Presumably, if the process can be shown to work, it can be expanded to other crops, such as wheat and corn. The initial experiment will cost $11 million and will last for three years.
Making food crops engines of carbon capture is not the entire solution to climate change. But it is a more sensible part of it than waging war on the fossil fuel industry and hoping people will be forced to buy expensive electric cars because gasoline is near $5 a gallon on average — and much more in liberal states such as California.
It has become conventional wisdom that the Democrats are in for a red wave of a shellacking in the midterm elections. The recent election to Congress of Mayra Flores, a Mexican-born Republican from a Hispanic-majority district in South Texas, is seen to be a prelude to the coming electoral massacre that the Democrats face. Biden’s recent exhortation of the oil companies to increase production, which his very policies have been designed to prevent, is a futile and panicky attempt to stave off disaster.
Nothing can save congressional Democrats. But Biden will be afforded the same opportunity to reboot his administration that former President Bill Clinton had after the Gingrich Revolution of 1994. The first two years of the Clinton administration consisted of attempts to pass liberal policies, such as an abortive healthcare reform bill championed by then-first lady Hillary Clinton. After 1994, Clinton pivoted toward the center and declared that the “era of big government is over.” His presidency featured a number of successes, at least until the Monica Lewinsky affair blew it up.
In 2023, seeing many of his liberal allies involuntarily retired to the private sector, Biden could declare, “The era of the Green New Deal is over.” Then he could rescind his executive orders that have placed a boot on the neck of the fossil fuel companies and pivot toward encouraging carbon capture, including the idea of turning food crops into carbon sinks.
The progressive Left will not be happy with anything that does not destroy the fossil fuel industry. The anti-GMO crowd will be especially irate. But Biden, because of his advanced age, is not likely to run for president successfully again. That fact will be oddly liberating to a man who has sought the presidency for decades only to acquire it in the winter of his life. Going out with a winning policy would be legacy-making, not to mention good for the country. Biden could spend the rest of whatever years he has left appreciating that.
