A controversial plan to store CO2 deep under Lake Maurepas was intended to greatly limit greenhouse gas emissions from a nearby industrial plant, but a new proposal raises the possibility that significantly less will be sequestered.

(…) just months after receiving the state’s blessing for air emissions based on that low-carbon vision, Air Products has asked for a do-over.

The proposed change could allow the [Air Products’ project called] Louisiana Clean Energy Complex to become among the top 25 industrial emitters of greenhouse gases in the state, (…)

Some environmental groups, which have opposed carbon capture projects because they claim they won’t live up to the storage rates being promised, speculated the air permit changes indicate the company is trying to hedge its bets.

Gov. Jeff Landry has also instituted a temporary moratorium on new underground carbon injection permit applications to prioritize a review of existing applications. Six projects were fast-tracked under the order, but Air Products’ permit wasn’t one of them.

This community is evolving from being just about CDR to include all CO₂ capture, removal, utilization, sequestration & storage technologies. So let’s discuss everything related to:

Carbon Capture and Storage (CCS)
Carbon Capture, Utilization, and Storage (CCUS)
Direct Air Capture (DAC) / Direct Air Carbon Capture and Sequestration (DACCS)
Carbon Dioxide Removal (CDR) / Greenhouse Gas Removal (GGR)
etc

While many climate scientists have reservations about CCS, the crisis has now grown so acute that almost all the net zero pathways modeled by the U.N.-backed Intergovernmental Panel on Climate Change (IPCC) and the Paris-based International Energy Agency (IEA) envision huge deployments of the technology by mid-century. Governments have also embraced the prospect that CCS could be a cost-effective means for reducing emissions without disrupting fossil fuel-based economies.[1]

Perhaps, it could be considered alarming that these technologies are often intertwined with fossil fuel companies. These corporations use them as an excuse not to phase out their production, while portraying themselves as part of the solution. (see: Exxon Mobil, BP, Shell, Chevron, TotalEnergies)

Carbon Capture and Storage (CCS), according to the definition by the IPCC, is a process that captures CO₂ from a point-source.

The terms CCS and Carbon Capture, Utilization, and Storage (CCUS) are closely related and often used interchangeably. Both terms have been used predominantly to refer to Enhanced Oil Recovery (EOR) a process in which captured CO₂ is injected into partially depleted oil reservoirs in order to extract more oil.

Some sources use the term CCS, CCU, or CCUS more broadly, encompassing methods such as Direct Air Capture (DAC) or Direct Air Carbon Capture and Sequestration (DACCS), as well tree-planting which remove CO₂ from the air.

Carbon Dioxide Removal (CDR) is defined by the IPCC as: “Anthropogenic activities removing CO₂ from the atmosphere and durably storing it in geological, terrestrial, or ocean reservoirs, or in products.”

Synonyms for CDR include Greenhouse Gas Removal (GGR), negative emissions technology, and carbon removal. The term geoengineering (or climate engineering) is sometimes used in the scientific literature for CDR. The terms geoengineering or climate engineering are no longer used in IPCC reports.
