Burke & Gambhir (2022): Policy incentives for Greenhouse Gas Removal Techniques: the risks of premature inclusion in carbon markets and the need for a multi-pronged policy framework

Joshua Burke and Ajay Gambhir IN: Energy and Climate Change, 100074, 2022;

Here the authors identify three risks associated with using carbon markets as the sole, or main, policy lever to encourage the deployment of GGR (Greenhouse Gas Removal) techniques. The categorisation of risks stems from discussions with policymakers in the UK and a review of the broader literature on carbon markets and GGR.


Ahlström et al. (2022): Sustainable Aviation Fuels – Options for Negative Emissions and High Carbon Efficiency

Johan M. Ahlström, Yawer Jafri, Elisabeth Wetterlund, Erik Furusjö; 59 pp. available at SSRN,

The authors investigate seven different pathways for producing aviation biofuels coupled with either bio-energy carbon capture and storage (BECCS), or bio-energy carbon capture and utilization (BECCU). Both options allow for increased efficiency regarding utilization of feedstock carbon. The analysis uses process-level carbon- and energy balances, with carbon efficiency, climate impact and LCOP as primary performance indicators.


Springer Book: Transportation in a Net Zero World: Transitioning Towards Low Carbon Public Transport

Kathryn G. Logan, Astley Hastings, John D. Nelson (Eds.), Green Energy and Technology. Springer, Cham.

This book discusses the importance of transitioning from conventionally fuelled, electric and hydrogen personal vehicles towards low carbon electric and hydrogen public transport. It presents international comparisons and case studies of countries who have successfully and unsuccessfully implemented policies to reduce their emissions from land-based transport.


Nature: IPCC’s starkest message yet: extreme steps needed to avert climate disaster

by Jeff Tollefson IN: Nature

„Radical emissions cuts combined with some atmospheric carbon removal are the only hope to limit global warming to 1.5 °C, scientists warn.“ Some key points of the recent IPCC reports are mentioned and statements of e.g. Inger Andersen, executive director of the UN Environment Programme, as well as of Oliver Geden, a social scientist with the German Institute for International and Security Affairs in Berlin, a lead author on the report, are given.


Nature – Liew et al. (2022): Carbon-negative production of acetone and isopropanol by gas fermentation at industrial pilot scale

Fungmin Eric Liew, Robert Nogle, Tanus Abdalla, Blake J. Rasor, Christina Canter, Rasmus O. Jensen, Lan Wang, Jonathan Strutz, Payal Chirania, Sashini De Tissera, + 17 authors IN: Nat Biotechnol 40, 335–344 (2022).

The authors describe the development of a carbon-negative fermentation route to producing the industrially important chemicals acetone and isopropanol from abundant, low-cost waste gas feedstocks, such as industrial emissions and syngas. Unlike traditional production processes, which result in release of greenhouse gases, this process fixes carbon. These results show that engineered acetogens enable sustainable, high-efficiency, high-selectivity chemicals production.


Wan Yun (2022): A techno-economic review on carbon capture, utilisation and storage systems for achieving a net-zero CO2 emissions future

Hong, Wan Yun IN: Carbon Capture Science & Technology, 2022, 100044,

This article aims to provide a general techno-economic review of CCUS systems. The technology readiness, technical performance, energy requirement and cost associated with CO2 capture, separation, transport, utilisation and storage technologies were discussed and compared.


Solid Carbon: A Climate Mitigation Partnership Advancing Stable Negative Emissions

Solid Carbon is an project to permanently and safely sequester carbon dioxide (CO2) as rock. The vision is to extract CO2 directly from the air or ocean. Then, using deep ocean technology powered by ocean-based wind and solar energy, inject the CO2 into the subseafloor basalt, where it mineralizes into solid carbonate rock. A PICS (Pacific Institute for Climate Solutions) Theme Partnership – Project; began October 1, 2019 with project Duration of four years. Lead PI: Dr. David S. Goldberg; a new explainer video is relased.
