„This study explores the mechanisms behind cost-optimal BECCS deployment with evolving regional CO2[nbsp]removal targets and energy sectors to provide insights into the ways in which different regional players will interact as a function of their bio-geophysical endowments and their ability to trade these assets. An important finding is that inter-regional cooperation—in choosing the right burden-sharing principle to establish regional targets—and collaboration—in trading negative emissions credits and biomass—are central to sustainably and affordably meeting these targets.“
PR Newswire: Carbon Capture and Sequestration Technology Could Play Key Role in Deeply Decarbonizing Electricity Grids, According to Study by Brattle Economists
„A new[nbsp]study[nbsp]by consultants at[nbsp]The Brattle Group[nbsp]assesses the cost-effectiveness of carbon capture and sequestration[nbsp](CCS) for utilities in meeting decarbonization goals. The study shows that some opportunities currently exist to retrofit coal-fired power plants with CCS at low net costs. In the future, the economics of CCS are likely to become more favorable, as the value of emission-free dispatchable energy in deeply decarbonized systems, which CCS can provide, is likely to be very large.[nbsp]“

„In our recent paper “Three Prongs for a Prudent Climate Policy,” Richard Zeckhauser and I evaluate a broader policy portfolio to combat climate change. In particular, we explore adding amelioration — through solar radiation management, or SRM — and adaptation to the emissions mitigation approach to climate change policy.“

IEAGHG Technical Report (2020): Value of Emerging and Enabling Technologies in Reducing Costs, Risks & Timescales for CCS
IEAGHG Technical Report (2020): Value of Emerging and Enabling Technologies in Reducing Costs, Risks [&] Timescales for CCS.
„This study was a horizon scanning exercise that aimed to understand the relevance of digital and enabling technologies for CCS and assess what benefits these technologies could offer to the large-scale deployment of CCS. Current R[&]D into the reduction of costs, risks, timescales and challenges in CCS primarily focusses on conventional improvement methods; emerging and enabling technologies have the potential to offer more opportunities for cost and risk reduction.“

„[T]his paper quantifies the initial and operating financial costs and initial and operating equivalent CO2[nbsp](CO2eq) emissions of the specialised aircraft-based SAI delivery system developed with relatively high-fidelity tools in part 1 of this series. We analyse an interval of operating conditions, within which we devote special attention to four injection scenarios outlined in part 1: Three scenarios where H2SO4[nbsp]vapour is directly injected at several dispersion rates and one SO2[nbsp]injection scenario.“
