Butnar, Isabela, et al. (2020): The Role of Bioenergy for Global Deep Decarbonization: CO 2 Removal or Low‐carbon Energy?

Butnar, Isabela, Oliver Broad, Baltazar Solano Rodriguez, and Paul E. Dodds (2020): The Role of Bioenergy for Global Deep Decarbonization: CO2 Removal or Low‐carbon Energy? GCB Bioenergy, January. https://doi.org/10.1111/gcbb.12666.

"‌We use a global integrated assessment model, TIAM‐UCL, to investigate the role of bioenergy within the global energy system when direct air capture and afforestation are available as cost‐competitive alternatives to BECCS. We find that the presence of other CO2 removal technologies does not reduce the pressure on biomass resources but changes the use of bioenergy for climate mitigation."

E4tech: Bioenergy and hydrogen & fuel cells identified as key areas for UK Government innovation support

"Investing in the deployment of early commercial gasification based plants, and building on the UK’s expertise in Miscanthus breeding and use, were identified as areas that the UK government should support. In hydrogen and fuel cells, bringing down the cost of both electrolysers and fuel cells through advanced manufacturing techniques and lower cost materials were identified as focus areas, to enable their widespread use in hydrogen production and transport."

Hu, Bin; et al. (2020): Can bioenergy carbon capture and storage aggravate global water crisis?

Hu, Bin; Zhang, Yilun; Li, Yi; Teng, Yanguo; Yue, Weifeng (2020): Can bioenergy carbon capture and storage aggravate global water crisis? In Science of the Total Environment, p. 136856. DOI: 10.1016/j.scitotenv.2020.136856.

"A bottom-up analysis approach was applied in this paper to calculating water consumption for BECCS and estimating water quality deterioration caused by increasing fertilizer and pesticide application. The results indicated that water usage of BECCS was equal to adding 12.86%–16.64% (switchgrass) and 17.59%–26.06% (miscanthus) additional water stress on global available water resources at 2100. Additional N fertilizer application in 2100 would be equal to over 84%, 55% and 42% for both switchgrass and miscanthus under three CCS capture efficiency scenarios, respectively, comparing to such global scale in 2012."

Merk, Christine; et al. (2019): Public Perceptions of Climate Engineering: Laypersons’ Acceptance at Different Levels of Knowledge and Intensities of Deliberation

Merk, Christine, Geraldine Klaus, Julia Pohlers, Andreas Ernst, Konrad Ott, and Katrin Rehdanz (2019): Public Perceptions of Climate Engineering: Laypersons’ Acceptance at Different Levels of Knowledge and Intensities of Deliberation. GAIA - Ecological Perspectives for Science and Society 28 (4): 348–55. https://doi.org/10.14512/gaia.28.4.6.

"‌We look at laypersons’ perceptions of BECCS and SAI at three stylized stages of increasing knowledge and deliberation. We found a high level of uncertainty among survey respondents as to whether to accept the use of these methods, which decreases when additional information is supplied by stakeholders."

Klaus, Geraldine; et al. (2019): Psychological factors influencing laypersons’ acceptance of climate engineering, climate change mitigation and business as usual scenarios

Klaus, Geraldine; Ernst, Andreas; Oswald, Lisa (2019): Psychological factors influencing laypersons’ acceptance of climate engineering, climate change mitigation and business as usual scenarios. In Technology in Society, p. 101222. DOI: 10.1016/j.techsoc.2019.101222.

"In July 2017, we assessed public reactions from the German population in a representative online survey. Participants were given a brief text informing them about climate change and one of four different scenarios in a between-subject design (N = 678). Two of the scenarios described the use of climate engineering technologies - stratospheric aerosol injection (SAI) and bio-energy with carbon capture and storage (BECCS) - one of them covered conventional mitigation strategies and the fourth group was given an outline of the business-as-usual (BAU) approach."

Denton Daily: Caution urged over use of ‘carbon unicorns‘ to limit warming

"Early drafts said it would require machines to suck carbon out of the air. The ideas are unrealistic, said one expert, calling them 'carbon unicorns'."

Butnar, I., et al. (2019): A Deep Dive into the Modelling Assumptions for Biomass with Carbon Capture and Storage (BECCS): A Transparency Exercise

Butnar, Isabela, Pei-Hao Li, Neil Strachan, Joana Portugal Pereira, Ajay Gambhir, and Peter Smith (2019): A Deep Dive into the Modelling Assumptions for Biomass with Carbon Capture and Storage (BECCS): A Transparency Exercise. Environmental Research Letters, November. https://doi.org/10.1088/1748-9326/ab5c3e.

‌"Through a structured review, we find that all IAMs communicate wider system assumptions and major cost assumptions transparently. This quality however fades as we dig deeper into modelling details."
