Report: Technology Readiness Assessment, Costs and Limitations of five shortlisted NETs

Kenneth Möllersten, Raza Naqvi, Mälardalen University, Report of the NET-RAPIDO Project: Negative emission technologies: readiness assessment, policy instrument design, options for governance and dialogue, 77 pp.

This report presents an in-depth technology readiness, cost assessment and an analysis of practical deployment barriers for NETs along with an analysis of related knowledge gaps and research needs. The selected NETs are (i) bioenergy with carbon capture and storage (BECCS); (ii) direct air capture and storage (DACCS); (iii) large-scale afforestation and reforestation; (iv) soil carbon sequestration; (v) Biochar as soil additive; (vi) Enhanced Weathering; (vii) Accelerated Mineralization; (viii) Ocean fertilization.

Nature – Buss et al. (2022): Mineral-enriched biochar delivers enhanced nutrient recovery and carbon dioxide removal

Wolfram Buss, Christian Wurzer, David A. C. Manning, Eelco J. Rohling, Justin Borevitz, Ondřej Mašek IN: Commun Earth Environ 3, 67 (2022). https://doi.org/10.1038/s43247-022-00394-w

Biochar production via biomass pyrolysis with subsequent burial in soils provides a CDR technology that is ready for implementation, yet uptake requires acceleration; notably, through generation of cost reductions and co-benefits. Here the authors determined that biomass enrichment (doping) with refined minerals, mineral by-products, or ground rocks reduces carbon loss during pyrolysis, lowering carbon dioxide removal costs by 17% to US$ 80–150 t−1 CO2, with 30% savings feasible at higher biomass costs.

The Green Carbon Webinar is starting again

Deadline Call for speakers: 6th February 2022

The 5th webinar series (UK Biochar Research Centre, University of Edinburgh) will be running from February to June 2022 with 2 bi-weekly presentations. Therefore, they are looking for enthusiastic academics and professionals to present their work. The webinar series will focus on the production, characterisation and application of advanced carbon materials from biomass, i.e. biochar, hydrochar and activated carbon.

How to secure carbon removal for your net zero pledge?

by PuroEarth

A webinar with CEO, Antti Vihavainen, he talks how Pre-CORC takeoff agreements work and meet the supplier of negative emissions: Carbo Culture. Carbo Culture is a Puro.earth current and Pre-CORC supplier of biochar-based technology to permanently keep carbon from the atmosphere. Tim Preisenhammer, Head of Commercialization, talks about the firm’s plans for a new facility, long term vision and how your company can contribute to reaching these ambitious goals.

Biomass to biochar – maximizing the Carbon Value

by the Center for Sustaining Agriculture and Natural Resources (Washington State University)

For these up to date report, fourty biochar producers, practitioners, scientists, and engineers held a virtual workshop in April 2020 to chart a roadmap (184 pages, summary 18 pages) for future development of the biochar industry in the Pacific Northwest and beyond.

Video: Can we remove carbon from the atmosphere? (True Planet)

„There is no ‘magic’ technology to solve climate change, says Professor Cameron Hepburn, Director and Professor of Environmental Economics at Oxford’s Smith School and director of the university’s Economics of Sustainability programme. ‘I wish there were,’ he says. ‘But we have to use all the existing tricks we have in the book as fast as possible to reduce emissions.’ Professor Hepburn emphasises there are some really interesting new technologies – and he thinks we should work to scale these up. In the meantime, he says, we already have some very old technology – the humble tree, which has been doing an important job for millennia – and is making a real contribution to reducing climate change. But Professor Hepburn says that right now, far from rewilding and restoring our ecosystems, we are deforesting and damaging nature with harmful agricultural practices. That needs to change. ‘Used together these various techniques…are going to make quite a big contribution to addressing climate change…what’s stopping us?’ Part of the problem, he says, is that somebody has to pay – and we need to talk about how to achieve that, without relying entirely on the taxpayer. But economics is only part of this, he says. We also need to think about a range of complex issues from politics to equity and beliefs – but, critically, the public needs to be on-board.“

Tech Crunch: Made of Air, a maker of ‘carbon negative’ thermoplastics, locks in $5.8M

„Berlin-based climate tech startup Made of Air has closed a €5 million (~$5.8 million) seed funding round, led by Norwegian sustainability-focused family fund, TD Veen. […] As the name (kind of) implies, Made of Air (MoA) is producing durable materials for a variety of use cases that make use of (pyrolyzed) wood waste in order to lock up carbon for long periods in the resulting hardened carbon-negative thermoplastic compound. (Which is literally made from biochar and bioplastics).“
