Carbon dioxide capture and utilization, and sequestration (CCUS) comprises both the large‐scale capture of CO2 (via direct capture from air, ocean, or point sources), functional utilization of concentrated CO2 for the production of value‐added products, and long term sequestration. A wide range of products ranging from low to high value can be generated from CO2 through CCU, but these products come at an energy price, and not all products will achieve net negative emissions (for example, conversion of fossil CO2 to liquid fuels). Selecting optimal combinations of capture, conversion technologies and target products or geologic sequestration, and then coupling these technologies with CO2 sources and the necessary energy infrastructure is an enormous challenge that has gone largely unaddressed. In this study, we develop system‐wide strategies for CCUS technologies that can offer negative emissions at meaningful scales. We apply techno‐economic analysis (TEA) and life cycle assessment (LCA) to help identify emerging negative emissions technologies that can be implemented to capture CO2 from various dilute sources (air, ocean, other biogenic sources), as well as to understand potential technological bottlenecks in capture, utilization, and sequestration of these streams. We focus on those that are emerging from research efforts within the Lawrence Berkeley National Laboratory (e.g., use of electrochemical methods for CO2 conversion, novel CO2 sorbents, such as metal organic frameworks, MOFs, and sequestration in basalt formations).

Alabama’s National Carbon Capture Center successfully tests carbon-reduction technology for concrete production

Read the full story from Alabama NewsCenter.

A pioneering technology that can permanently store carbon dioxide (CO2) in concrete blocks has gone through successful testing at the Alabama-based National Carbon Capture Center (NCCC).

CarbonBuilt and the NCCC, located next to Alabama Power’s Plant Gaston in Wilsonville, announced the completion of the multiweek test of carbon utilization and concrete production technology. The test successfully injected COfrom the flue gas streams of the NCCC’s natural gas testing system and Plant Gaston’s coal-fired generating unit into more than 5,000 concrete blocks, where the carbon is now “stored for good,” according to a news release.

IEEFA U.S.: Coal-fired carbon capture projects are waste of tax dollars

Read the full story from IEEFA.

The federal government’s support for carbon capture projects at coal-fired power plants may be politically necessary (see Sen. Joe Manchin, D-W.Va.), but it is environmentally and fiscally misguided. The potential for Department of Energy funding and the lure of federal tax credits are pushing plant owners and avaricious developers to push for the conversion of aging coal plants into the equivalent of carbon dioxide factories instead of moving toward cleaner, cheaper alternatives.

The carbon capture retrofit proposal touted by Enchant Energy for the coal-fired San Juan Generating Station in New Mexico is the most egregious example. The company, which entered the scene as Acme Equities under the direction of a New York hedge fund operator, promised it would round up private investors to fund a $1.5 billion effort to capture as much as 90 percent of the CO2 emitted at the power plant.

New gas turbines ‘better be flexible’ to someday accept carbon capture or hydrogen: New EEI chairman

Natural gas is a critical part of the U.S. transition to a decarbonized power sector, top executives from three major utilities agreed on Tuesday. But its role will decline over time, and gas power plants will have to adapt to new technologies and fuels to reduce the risk of becoming stranded assets, said the recently elected board members of the investor-owned utility advocacy group, Edison Electric Institute (EEI).

“There’s no way to get to net zero without gas transitioning and eventually being either fully captured in terms of carbon or replaced with a different fuel,” Gerry Anderson, executive chairman at DTE Energy, said Tuesday at EEI’s “Road to Net Zero” conference. “As we permit new natural gas turbines, I think all of us need to be aware that someday they better be flexible enough to accept carbon capture, or in some way flexible to accept hydrogen,” he continued.

Anderson was elected this week as the new chairman of EEI’s board, alongside two new vice chairmen who echoed the persisting importance of natural gas: Warner Baxter, chairman, president and CEO of Ameren Corp., and Pedro Pizarro, president and CEO of Edison International.

Many people have predicted that carbon capture will play a key role in meeting emissions-reductions goals set forth by the Paris Climate Agreement. Others have been skeptical about the technology and economics around CCUS. Join us for a conversation science, financial and policy issues involved in whether CCUS may soon become important in hard-to-decarbonize sectors such as manufacturing and heavy industry.

How carbon-intensive industries can scale up CO2 recycling

Read the full story in Horizons.

New technologies that capture and recycle carbon dioxide from industrial processes such as steel and cement making will be vital if the EU is to meet its goal of slashing greenhouse gas emissions by at least 55% by 2030 and down to zero by 2050. However, while solutions are emerging, more work is needed in order to roll them out at scale, experts say.

Is carbon the ‘crop’ of the future?

Read the full story in High Plains Journal.

An increasing awareness and concern about the environment, changes in government policy, America’s re-entry into the Paris Agreement and a robust demand for carbon offsets all point toward an appetite for a different type of agricultural crop—carbon.

“There has been an increasing amount of discussion on how to create a way for farmers to earn credits for the climate-friendly practices they have implemented or will implement on their operations,” said Joe Outlaw, Ph.D., co-director of the Agriculture and Food Policy Center at the Texas A&M College of Agriculture and Life Sciences and economist with the Texas A&M AgriLife Extension Service, Bryan-College Station. “One of these ways is through carbon farming that would allow for the capture or sequestration of soil organic carbon, making it possible for the sale of carbon credits to corporations so they may offset their greenhouse gas emissions.”

However, many questions on the efficacy of carbon farming and its worth to the farmer are as yet unanswered. Will there be incentives to attract a sufficient number of farmers for it to work? How much trouble will it be to implement and monitor these carbon capture methods? Will some farmers benefit more than others? Will farmers be credited for the actions they have already taken to reduce greenhouse gas emissions?

Net Zero by 2050: A Roadmap for the Global Energy Sector

Download the document.

The number of countries announcing pledges to achieve net-zero emissions over the coming decades continues to grow. But the pledges by governments to date – even if fully achieved – fall well short of what is required to bring global energy-related carbon dioxide emissions to net zero by 2050 and give the world an even chance of limiting the global temperature rise to 1.5 °C.

This special report is the world’s first comprehensive study of how to transition to a net zero energy system by 2050 while ensuring stable and affordable energy supplies, providing universal energy access, and enabling robust economic growth. It sets out a cost-effective and economically productive pathway, resulting in a clean, dynamic and resilient energy economy dominated by renewables like solar and wind instead of fossil fuels. The report also examines key uncertainties, such as the roles of bioenergy, carbon capture and behavioral changes in reaching net zero.

NREL details cost declines needed for long-duration storage to displace nuclear, gas with CCS

Read the full story at Utility Dive.

More research is needed to understand the economics of long-duration and seasonal storage technologies to make sure they can play a role in decarbonizing the electric grid, according to a new article published in the journal Nature Energy.

The article, written by National Renewable Energy Laboratory (NREL) research engineer Omar J. Guerra, builds on a previous study that looked at the cost-effectiveness of deploying long-duration energy storage (LDES) in conjunction with renewable energy to decarbonize the grid. That study, published in March in Nature Energy, found that LDES storage costs and discharge efficiency need to improve in order to displace nuclear power or natural gas power plants as sources of grid reliability.

Although there are “promising opportunities” for LDES, Guerra writes, “comprehensive modeling of multi-scale energy storage technologies remains a major challenge towards achieving complete understanding of the value of storage technologies in achieving carbon-free or high renewable power systems.”
