This week on Inside Appalachia, we look back at a shocking crime near the Appalachian Trail and speak to the author of a book that re-examines the case. We also sample a beloved Lenten staple made in Charleston, West Virginia. It’s a Yugoslavian fish stew that has a little bit of everything. And we talk with the poet laureate of Blair County, Pennsylvania, who invented the demi-sonnet.
Plugged In: What Is Carbon Capture and Storage, and Why Do We Need It?

A bipartisan group in Congress, including several Ohio Valley lawmakers, is pushing for more federal support for poorly understood technology known as carbon capture and storage. The lawmakers and an uncommon alliance of labor, business, and environmental groups want to pass legislation called the FUTURE Act which would speed commercial deployment of technology that reduces carbon dioxide emissions from industries that burn fossil fuels.
Such technology has been in development for decades. Today, a number of commercial-scale projects exist demonstrating various technologies that “scrub” CO2 from the waste stream and store it underground are possible. However, scaling those projects up to levels that would affect the atmosphere in significant ways is still prohibitively expensive.
The new legislation is the latest in a long line of federal attempts to help scale up carbon capture, most of which have failed. But as CO2 reaches record levels in the atmosphere and scientific evidence mounts about the clear danger of climate change, even some who were skeptical about the technology are now willing to reconsider carbon capture and storage.
Change of Mind
Akshat Rathi is a Ph.D. chemical engineer-turned journalist based in London, where he writes for the business news outlet Quartz.
His interest and skepticism about carbon storage as a solution to global carbon emission woes set him on a year-long trip around the world to research the topic for a series of reports called “The Race to Zero Emissions.”
“I was highly skeptical,” he said. “The idea that you would be able to capture it and just bury it? As if people are going to bury the money underground? Because it would cost you to capture that carbon and the next day you’re simply going to bury it?”
After traveling to eight countries and talking to hundreds of people, Rathi said he has a new perspective.
“I have changed my mind,” he said. “This technology is actually feasible.”
He’s quick to point out that other developments will remain critically important, such as investment in renewable energy and efficiency, but he’s now convinced carbon capture will need to be in the mix.
“No serious body, no academic body, no scientists, no government officials would say that we will stop burning fossil fuels” in the coming decades, he said. While solar, wind and other clean energy developments are booming, Rathi said they still will fall short of demand. “The world requires so much energy, and the amount of energy we will consume will keep increasing as the population keeps growing till about 2050. And we will be burning fossil fuels.”
“Carbon capture is just one part, but a key part of the solution,” he said. “I’m hopeful that the system exists to take this and make this something that could save humanity from climate change.”
For decades researchers in the Ohio Valley and around the world have been focused on how to burn fossil fuels in more environmentally friendly ways. The pursuit of “clean coal” has yielded some innovations by improving power plant efficiency and reducing pollutants linked to smog and soot. But pulling CO2 from smokestacks is still a complex, expensive venture.
“The amount we capture today is about 40 million tons,” Akshat Rathi said. “Just to put that in perspective, we produce 40 BILLION tons. So we’re capturing .1 percent of all emissions that we put out in the air.”
That carbon dump, releasing CO2 that had been sequestered in the earth eons ago, puts us on a collision course with climate change. International goals set in the Paris Climate Agreement require dramatically reducing CO2 emissions globally to “net zero” by 2050.
“The ‘zero’ doesn’t mean we don’t burn fossil fuels at all,” Rathi said. “It means we burn fossil fuels with carbon capture, or there are technologies that can pull carbon dioxide from the air – negative emissions technologies.”
While the United States has announced intentions to pull out of the Paris Agreement – an act that will take many years to complete – the only other country in the world that wasn’t signed on, Syria, has now also committed to the agreement.
“Carbon dioxide is not a U.S.-only problem,” Rathi said, “it’s a global problem. So even if the U.S. doesn’t want to reduce emissions, other countries do.”
Many of the technologies for carbon capture have been in development since the 70s. The Department of Energy’s National Energy Technology Laboratory in Morgantown, West Virginia, has been researching various aspects of carbon capture technology for decades.
About two dozen commercial scale projects are in operation around the world, including a project supported by NETL. A relatively small coal-fired power plant in Texas called Petra Nova has successfully captured and stored 90 percent of carbon emissions in its first year — about a million tons of CO2 — making it the largest “clean coal” facility in the world, according to the U.S. Department of Energy.
“We’re spending tens of billions of dollars investing in this infrastructure of all these pipelines moving natural gas to natural gas generating plants which are 40 to 60 year assets. So we’re going to be burning gas for a long time,” he said, noting that gas still produces plenty of carbon emissions.
“The same principals of carbon sequestration for coal plants can apply and will need to apply to gas plants in order to achieve the significant reductions in greenhouses gas necessary to avoid increasing temperature globally.”
But the record for successfully deploying carbon capture is spotty, at best. What might have been the flagship U.S. project ended earlier this year when the Southern Company pulled the plug on a plan to turn coal into gas and then capture carbon emissions at its new facility in Kemper County, Mississippi. The plant will instead burn natural gas. The earlier FutureGen project, launched by the Bush administration, also fizzled before a promised low-emissions power plant was built.
Question of Will
Rathi said running carbon capture technologies and the infrastructure to pump and store the CO2 requires a lot of energy.
“On a typical power plant right now you are spending about 10 to 20 percent of the energy that you produce to do the capturing,” he said. “That may seem a lot but that’s where our value system comes in place. Are we really interested in doing this?”
Rathi said it will take significant government incentives, like carbon taxes, around the globe to scale up implementation of carbon capture and storage. He estimates meeting goals the international community has set will require about $500 billion annually, or about 1 percent of global GDP.
On this West Virginia Morning, with the 60-day legislative session over, lawmakers and West Virginians have a chance to reflect on what was accomplished – and look forward to what still needs to be done for the state. Chris Schulz covered the Senate all session and has one last look at the chamber’s activity.
Edible Mountain follows botanists, conservationists, and enthusiastic hobbyists in the field as they provide insight on sustainable forest foraging. The episodes are designed to increase appreciation and accessibility to the abundance found in Appalachia, celebrating the traditional knowledge and customs of Appalachian folk concerning plants and their medical, religious, and social uses.
On this West Virginia Morning, several lawmakers called the just completed legislative session historic, while others were concerned over the focus on major economic development rather than helping working West Virginians. Randy Yohe has a final session wrap from the House of Delegates.
