Video: Recording: Webinar: Negative emissions and net zero: how do technologies for carbon dioxide removal measure up? (CCUS Projects Network)

"The European Union is committed to keeping the average temperature rise to well below 2°C, preferably closer to 1.5°C, which according to the Intergovernmental Panel on Climate Change (IPCC) requires bringing global GHG emissions to net zero by 2050. The IPCC scenarios show that alongside implementing other climate mitigation policies it is essential to remove CO2 from the atmosphere, known as carbon dioxide removal (CDR) which includes negative emission technologies (NETs). Various options are being reviewed and discussed, including both nature-based solutions and CCS-based solutions. The most common CCS-related solutions identified are direct air carbon capture and storage (DACCS) and CCS on energy production from biomass (BECCS). This event will discuss policy mechanisms for the delivery of CDR, storage longevity and the role of offsetting, and present some real project examples and the potential range of biogenic sources that combined with CCS can enable CDR."

Arens, Christof (Ed.) (2021): Ensuring longterm ambition. Paris-proofing of baseline setting as a means for alignment with the Paris Agreement’s long-term objectives (Wuppertal Institute for Climate, Environment and Energy)

Arens, Christof (Ed.) (2021): Ensuring longterm ambition. Paris-proofing of baseline setting as a means for alignment with the Paris Agreement’s long-term objectives. Wuppertal Institute for Climate, Environment and Energy. Wuppertal (Carbon Mechanisms Review, Vol. 9, No. 3). Available online at https://www.carbon-mechanisms.de/fileadmin/media/dokumente/Publikationen/CMR/CMR_03_2021_web_final.pdf.

"In this issue of the CMR, we take an in-depth look at the baselines discussion, starting with an analysis of the experience gained in the different carbon market arenas so far. We also present a Party perspective on the negotiation process and possible solutions for the associated agenda items. The cover feature is supplemented by a new proposal from the research community on how to technically solve baseline setting under the new Paris Agreement regime. Also in this issue, we look at how implementation of Article 6 activities can be promoted and assess actual capacity building needs. Finally, we explore the aviation sector and analyse the role of carbon markets in regulating GHG emissions from aviation as described in the European Commission’s recent “Fit for 55” proposal."

Joppa, Lucas; et al. (2021): Microsoft's million-tonne CO2-removal purchase - lessons for net zero

Joppa, Lucas; Luers, Amy; Willmott, Elizabeth; Friedmann, S. Julio; Hamburg, Steven P.; Broze, Rafael (2021): Microsoft's million-tonne CO2-removal purchase - lessons for net zero. In Nature 597 (7878), pp. 629–632. DOI: 10.1038/d41586-021-02606-3.

"Strengthen markets, measures and definitions for removing carbon dioxide from the atmosphere to fight climate change. In January this year, Microsoft made a major announcement: it had paid for the removal of 1.3 million tonnes of carbon dioxide from the atmosphere. Among its purchases were projects to expand forests in Peru, Nicaragua and the United States, as well as initiatives to regenerate soil across US farms. [...] Here we summarize the lessons learnt from Microsoft’s carbon-removal efforts, along with those from another early corporate procurement — the $9-million purchases of carbon removal in 2020 and 2021 by the US–Irish financial-infrastructure company Stripe. Although these are just two companies’ efforts, they are the first significant open solicitations focused exclusively on carbon removal. We write as a team composed of Microsoft staff working on the company’s carbon-negative programme and research scientists who analyse carbon reduction and removal strategies."

Du, Yang; et al. (2021): Zero- and negative-emissions fossil-fired power plants using CO2 capture by conventional aqueous amines

Du, Yang; Gao, Tianyu; Rochelle, Gary T.; Bhown, Abhoyjit S. (2021): Zero- and negative-emissions fossil-fired power plants using CO2 capture by conventional aqueous amines. In International Journal of Greenhouse Gas Control 111, p. 103473. DOI: 10.1016/j.ijggc.2021.103473.

"This work investigated the technical and economic feasibility of achieving zero and negative CO2 emissions in both pulverized coal (PC) and natural gas combined cycle (NGCC) power plants, using conventional amine scrubbing with 30 wt% aqueous monoethanolamine. In this work, we refer to “zero emissions” when the amount of CO2 in the exhaust flue gas is equal to that in the intake combustion air, and “negative emissions” when the amount of CO2 in the exhaust flue gas is less that in the intake combustion air. Increasing CO2 capture from 90% to that at zero-emissions for fossil-fired power plants can reduce global CO2 emissions by up to ∼1 Gt/y for the current global power generation mix. Even higher CO2 capture leads to negative emissions of the power plant with part of the CO2 from the intake air removed along with the fossil-fuel derived CO2. With an absorber configuration including a simple solvent intercooler, both PC and NGCC power plants can achieve zero-emissions with a ∼5% and ∼13% increase in CO2 avoidance costs, compared with the costs at 90% CO2 capture. The larger cost penalty for NGCC was mainly due to a temperature bulge at the absorber top. Replacing the simple solvent intercooler with a pump-around intercooler was able to reduce this cost penalty to ∼8%. Further decarbonization of flue gases from zero-emissions to direct air capture (DAC)-level of negative emissions (∼100 ppmv of CO2 in exhaust gases) has incremental costs of over $1000/t CO2 avoided for both PC and NGCC."

The New York Times: What’s the Least Bad Way to Cool the Planet?

"How to cool the planet? The energy infrastructure that powers our civilization must be rebuilt, replacing fossil fuels with carbon-free sources such as solar or nuclear. But even then, zeroing out emissions will not cool the planet. This is a direct consequence of the single most important fact about climate change: Warming is proportional to the cumulative emissions over the industrial era. [...] To cool the planet in this century, humans must either remove carbon from the air or use solar geoengineering, a temporary measure that may reduce peak temperatures, extreme storms and other climatic changes. Humans might make the planet Earth more reflective by adding tiny sulfuric acid droplets to the stratosphere from aircraft, whitening low-level clouds over the ocean by spraying sea salt into the air or by other interventions."

Vice: 'Carbon Footprint' and 'Net Zero' Don't Mean What You Think

"Words that imply strong emission reduction policies have adopted slippery meanings intended to imply companies are doing more to reduce emissions than they actually are."

Glenk, Klaus; et al. (2021): The opportunity cost of delaying climate action: Peatland restoration and resilience to climate change

Glenk, Klaus; Faccioli, Michela; Martin-Ortega, Julia; Schulze, Christoph; Potts, Jacqueline (2021): The opportunity cost of delaying climate action: Peatland restoration and resilience to climate change. In Global Environmental Change 70, p. 102323. DOI: 10.1016/j.gloenvcha.2021.102323.

"Ecosystem restoration and, in particular, peatland restoration, are considered a promising greenhouse gas (GHG) mitigation strategy to move towards net zero emissions. To remain within acceptable limits for projected warming scenarios, inaction with respect to GHG mitigation in the short term implies a need for even larger removals of GHGs in the longer term, which can be conceptualized as a ‘mitigation debt’. This paper explores the economic implications of delaying GHG mitigation through ecosystem restoration using data of a large survey (N = 1377) that included a choice experiment to elicit the public’s willingness to pay (WTP) for peatland restoration in Scotland, UK."

Rosa, Lorenzo; et al. (2021): The Role Of Beccs To Deliver Negative CO2 Emissions In Europe

Rosa, Lorenzo; Sanchez, Daniel; Mazzotti, Marco (2021): The Role Of Beccs To Deliver Negative CO2 Emissions In Europe. In SINTEF Proceedings (7). Available online at https://sintef.brage.unit.no/sintef-xmlui/bitstream/handle/11250/2780214/THE%20ROLE%20OF%20BECCS%20TO%20DELIVER%20NEGATIVE%20CO2%20EMISSIONS%20IN%20EUROPE.pdf?sequence=1&isAllowed=y.

"Bio-Energy with Carbon Capture and Storage (BECCS) is a key climate mitigation technology, which involves the capture and permanent sequestration of biogenic carbon dioxide (CO2). To reach net-zero-CO2-emissions by 2050, it is forecasted that many million tons of CO2 will have to be sequestered through BECCS in Europe. There are different industrial processes that utilize biomass for bio-energy production, namely, pulp and paper mills, biogas facilities, incinerators, and biomass-fired power plants. Moreover, crop residues, organic food waste, and livestock manure could be utilized to transform biomass from a poor energy carrier to an efficient carbon drawdown carrier through BECCS. Here, we quantify the techno-environmental potential for biogenic carbon dioxide removal considering prospective BECCS opportunities that do not require purpose-grown bio-energy plantations. Combining process engineering with a bottom-up assessment, we find that there are 200 million tons CO2 yr-1 that could be deployed for biogenic carbon dioxide removal through BECCS in Europe."
