The quest to capture and store carbon — and slow climate change — just
reached a new milestone

A new large-scale technology has launched
<http://www.adm.com/en-US/news/_layouts/PressReleaseDetail.aspx?ID=799> in
Decatur, Illinois that, by combining together corn-based fuels with the
burial of carbon dioxide deep underground, could potentially result in the
active removal of greenhouse gases from the atmosphere.

It’s an objective described as crucial by scientists hoping to control the
planet’s warming.

The facility operated by ethanol giant Archer Daniels Midland, dubbed
the Illinois Industrial Carbon Capture Project, arrives at a time of
uncertainty for the U.S. and global biofuels industry. It faces growing
competition from electric vehicles, and continuing struggles to move beyond
so-called “first generation” feedstocks like corn, which can create
conflicts with food supplies.

Some critics have also questioned the  technology — dubbed “bioenergy with
carbon capture and storage,” or BECCS

—
that marries together plants that pull carbon from the air as they grow,
and industrial applications that process or consume those plants to
generate energy, but also capture some of the resulting carbon and stow it
within the Earth.

The ADM plant could still be quite significant from a global climate
perspective. Computer models that seek to chart our planet’s energy and
climate future have leaned heavily on BECCS as a way to power future
transportation and electricity systems while nonetheless keeping the
planet’s warming below the dangerous level of 2 degrees Celsius.

“This is the first large scale project in the world on biofuels, and it
takes us down the road towards negative emissions, which is the exciting
part,” said Jeff Erikson, director of the Global CCS Institute. (The other
key BECCS idea — power plants that burn wood for electricity and then
capture the emissions — does not exist at a large scale, Erikson said.)

Yet the climate benefits  of driving cars with corn-based ethanol instead
of fossil fuels remain contested — even in combination with the CCS
technology.

“Because CCS benefits are independent, it should not be selectively used to
dress up the benefits of one carbon emitting fuel versus another,” said
Timothy Searchinger, a critic of biofuels
<http://science.sciencemag.org/content/319/5867/1238.full> with the World
Resources Institute, in a statement. “Coal, gasoline, natural gas and
bioenergy are precisely as good or as bad relative to each other as they
are regardless of CCS.”

The march towards launch of the Illinois project has been a remarkably
quiet one thus far. The local Decatur Herald & Review noted
<http://herald-review.com/business/energy/public-silent-as-adm-prepares-to-store-millions-more-tons/article_2f1e2215-4377-5730-bb23-a1c83b75259f.html>
in
December that a local Environmental Protection Agency hearing to review
ADM’s plans went off “with nobody showing up to submit comments about
changes to the permit.”

The Decatur project is expected to store 1.1 million tons of carbon dioxide
per year for five years in sandstone layers a mile and a half underground,
for a total storage of over 5 million tons. According to materials provided
by ADM, the geological formation involved, the Mt. Simon Sandstone, has
“the capacity to store billions of tons of CO2.”

The current ADM project builds on a prior, smaller scale project in
Illinois that over three years stored about a million tons of CO2, and
tested the sustainability of the geological sequestration of carbon dioxide
in sandstone, says Sallie Greenberg, a researcher with the Illinois State
Geological Survey who has collaborated on both projects.

“The significance of this is it is an upscale, more industrial scale
injection on the order of a million tons of carbon dioxide per year, so
this is a big step forward in terms of the commercialization of carbon
capture and storage,” said Greenberg.

At the Decatur plant, carbon dioxide is stripped out of the fermentation
process in which corn is converted to ethanol — which yields an almost
perfectly pure stream of carbon dioxide gas. That gas is then converted to
“supercritical,” fluid form and piped underground.

“The technology that we are using in Decatur can be a model for reducing
industrial carbon emissions around the world,” said ADM’s chief technology
officer, Todd Werpy, in a press statement
<http://www.adm.com/en-US/news/_layouts/PressReleaseDetail.aspx?ID=799>
 Friday.

Unlike in some other CCS projects, the carbon dioxide will not be used for
the purposes of so-called “enhanced oil recovery” from depleted oil fields,
Greenberg said. This may add to the economic viability of CCS technology,
but has drawn criticism because it promotes further use of fossil fuels.

The Energy Department praised the initiative. “Today’s announcement marks a
major step forward for the advancement of industrial carbon capture and
storage technologies,” said Doug Hollett, Acting Assistant Secretary for
Fossil Energy. That’s the division of the department that invested $ 141
million into ADM’s project as part of President Obama’s economic stimulus
bill in 2009.

Yet despite campaigning about the importance of “clean coal” and even
saying it is “committed to <https://www.whitehouse.gov/america-first-energy>
 clean coal technology <https://www.whitehouse.gov/america-first-energy>”
on the White House website, the Trump administration is aiming to slash
research funding for these kinds of technologies.

An OMB budget document
<http://www.eenews.net/assets/2017/03/28/document_gw_06.pdf>sent to Capitol
Hill last month, singled out the Energy Department’s Fossil Energy Research
and Development for a more than 50 percent budget cut for the remainder of
this year. It said the program could manage the cuts through “a reduction
in the number of R&D grant awards.”

In addition to the Archer Daniels Midland project, one other major CCS
facility opened in the U.S. this year — the Petra Nova plant
<https://www.washingtonpost.com/news/energy-environment/wp/2017/01/10/americas-first-clean-coal-plant-is-now-operational-and-another-is-on-the-way/>
in
Texas, which captured carbon dioxide from the process of burning coal for
electricity and then uses the stream of the gas for enhanced oil recovery.
It also received Energy Department funding.

Greenberg said it isn’t clear yet whether the entire process occurring in
Illinois will be proven to be carbon negative — to pull a net amount of
carbon out of the air and store it beneath the ground.

“There are lot of researchers who are looking at life cycle analysis, and
running those numbers, to make the case of whether it’s net negative,” she
said. “I think it’s probably about as close as you’re going to get. But I
think, really, for an answer to that, stay tuned, that’s one of the
research questions that we are all looking at quite closely.”
