Episode Summary
Executive Summary: Jason Jacobs interviews Deepika Nagabushin of Clean Air Task Force about decarbonized fossil energy and carbon capture. Deepika argues CCS should be treated as one tool in a broader climate portfolio: keep emissions out of the air, drive costs down with policy, incentives, and innovation, and use early markets like EOR to build infrastructure while scaling permanent saline storage and other utilization pathways.
Main Topics: What decarbonized fossil energy means (Priority: 5/5): Deepika explains that decarbonized fossil energy keeps using hydrocarbons but captures the resulting CO2 so the emissions do not enter the atmosphere. The goal is to make this option cost-competitive and widely deployable. How carbon capture and storage works (Priority: 5/5): The conversation covers the mechanics of CCS, including capturing flue gas or concentrated CO2 streams, transporting it, and storing it underground or using it in industrial applications. Policy and incentives as deployment levers (Priority: 5/5): Deepika emphasizes 45Q, state programs like California’s LCFS/CCS pathway, loan guarantees, contracts for differences, and government RD as the main tools to bridge the cost gap and accelerate adoption. Enhanced oil recovery as a near-term market (Priority: 4/5): EOR is presented as the largest current market for CO2 and a practical way to monetize captured carbon while building the CCS ecosystem, despite climate-community concerns. Barriers to scaling CCS (Priority: 4/5): Key barriers include high capture costs, varying economics by facility type, need for pipelines and sequestration infrastructure, financing risk, limited industry learning, and the need for more R&D. Fossil fuels, renewables, and the portfolio approach (Priority: 4/5): Deepika argues against single-solution thinking, saying the energy transition likely requires a mix of renewables, CCS, nuclear, and other technologies rather than relying on a sole pathway. Ethics, divestment, and working with oil majors (Priority: 3/5): The discussion addresses distrust of fossil fuel companies and divestment campaigns. Deepika says regulations, not trust, should govern outcomes, and advocates engaging firms to force decarbonization through policy.
Key Arguments: Decarbonized fossil energy is not about stopping fossil use immediately; it is about preventing CO2 from reaching the atmosphere when fossil fuels are used. Markets alone will not scale CCS fast enough; policy incentives and regulations are needed to make the technology financially viable. 45Q is a major step because it effectively places a price on captured carbon and improves project economics, though not enough for every facility. EOR can pay for captured CO2 and help build early CCS infrastructure, but it is not a silver bullet because available EOR capacity is limited. The climate problem is large enough that no single technology will solve it; a portfolio of solutions is more realistic and lower-cost. Even if a world without fossil fuels is desirable, Deepika argues it is not yet practical to assume we can transition fast enough without using CCS as a bridge and/or complement. Working with fossil fuel companies can be justified if policy and regulation force them to invest in decarbonization and clean technologies. The biggest bottleneck is not just technology but the surrounding ecosystem: financing, pipelines, storage sites, standards, and government-supported R&D.
Data Points: 45Q credit for geologic sequestration: $50 per ton - Tax credit for capturing and permanently sequestering one ton of CO2 45Q credit for EOR/utilization: $35 per ton - Tax credit for CO2 used in enhanced oil recovery or other utilization pathways US power sector CCS impact estimate: 49 million metric tons per year - CATF study estimate for annual CO2 capture by 2030 under 45Q economics Retrofitted fossil generation: About 45 units - Number of power units expected to be retrofitted in CATF’s study Retrofit capacity: Approximately 10 gigawatts - Approximate fossil-fired generation capacity fitted with carbon controls in CATF’s study Boundary Dam / Petra Nova re-engineering savings: 30% to 60% lower costs - Deepika notes these operating CCS plants said costs could be materially reduced with better design and learning-by-doing EOR life-cycle offset: 0.37 tons offset per ton injected - IEA study cited on net emissions impact of anthropogenic CO2 used in EOR EOR net reduction: 0.63 tons net reduction per ton injected - Derived from the cited life-cycle analysis after accounting for offsets US power sector target in IPCC two-degree scenario: About 46-50 million tons by 2030 - Deepika cites IPCC-style scenario needs for CCS deployment in the US power sector Global cumulative CCS need in 1.5°C scenario: 350 billion to 1.2 trillion metric tons - Deepika cites a large cumulative global capture requirement over time IEA estimated EOR capacity: About 140 billion tons - Used to argue EOR cannot meet total long-term global CCS demand Fusion timeline mentioned: ~15 years - Used as an example of long-horizon RD investment for breakthrough climate technologies
Pivotal Quotes: "our job is to identify how or make this happen, make decarbonized fossil fuel competitive from a cost point of view with fossil energy." — Deepika Nagabushin: Defines CATF’s mandate for the Decarbonized Fossil Energy Program "I don't think that we can rely on people to do the right thing. I'm just not sure that that's an approach I would bet my money on." — Deepika Nagabushin: Explaining why policy and regulation matter more than moral appeals to companies "I don't actually care. I don't actually care what solution we use. I think that what matters is that we're able to do it affordably, do it in time and get to that sort of carbon target." — Deepika Nagabushin: Her pragmatic stance on technology choice in climate solutions
Implications: For listeners and industry, the episode argues that CCS should be judged pragmatically as part of a broader decarbonization toolkit. Policy support, infrastructure buildout, and R&D are critical if CCS is to scale fast enough to matter.
