Titus et al. (2024): Techno-economic analysis of geothermal combined with direct and biomass-based carbon dioxide removal for high-temperature hydrothermal systems

K.A. Titus, David Dempsey, Rebecca A.M. Peer, Rosalind Archer IN: Geothermics, 125, https://doi.org/10.1016/j.geothermics.2024.103159

Here, the authors present a techno-economic comparison of renewable electricity generation coupled with either BECCS or DACCS at high-temperature, low-gas hydrothermal systems. They use a systems model that quantifies energy, carbon and financial flows through a generic hybrid power plant.

Bunya et al. (2024): Optimization and Tradeoff Analysis for Multiple Configurations of Bio-Energy with Carbon Capture and Storage Systems in Brazilian Sugarcane Ethanol Sector

Bruno Bunya, César A. R. Sotomonte, Alisson Aparecido Vitoriano Julio, João Luiz Junho Pereira, Túlio Augusto Zucareli de Souza, Matheus Brendon Francisco, Christian J. R. Coronado IN: Entropy, 26(8), 698, https://doi.org/10.3390/e26080698

This study seeks to carry out a thermodynamic optimization and analysis of a BECCS technology for a typical Brazilian cogeneration plant. To maximize generated net electrical energy (MWe) and carbon dioxide CO2 capture (Mt/year), this study evaluated six cogeneration systems integrated with a chemical absorption process using MEA. A key performance indicator (gCO2/kWh) was also evaluated.

Bio-based carbon dioxide removal encompasses a range of (1) natural sink enhancement concepts in agriculture and on organic soils including peatlands, and in forestry, (2) bio-based building materials, and (3) bioenergy production with CO2 capture and storage (BECCS). A common database on these concepts is crucial for their consideration in strategies and implementation. In this study, the authors analyse standardised factsheets on these concepts.

Fridahl et al. (2024): Potential and goal conflicts in reverse auction design for bioenergy with carbon capture and storage (BECCS)

Mathias Fridahl, Kenneth Möllersten, Liv Lundberg, Wilfried Rickels IN: Environmental Sciences Europe, 26, https://doi.org/10.1186/s12302-024-00971-0

Sweden seeks to lead the way in bringing Bioenergy with carbon capture and storage (BECCS) up to scale, introducing a EUR 3.6 billion reverse auction scheme to facilitate market entry of companies producing BECCS. The authors explore instrument design preferences among politicians, regulators, and prospective BECCS operators to identify trade-offs and explore feasible policy design. Based on 35 interviews with experts in the latent BECCS sector in Sweden, the authors identify under which circumstances prospective operators would be willing to place bids and discuss how actor preferences both align with and challenge auction theory.

Yang et al. (2024): Policy support for BECCS and DACCS in Europe: the view of market participants

Pu Yang, Sam Fankhauser, Stephen M Smith, Ingrid Sundvor, Stephanie Hirmer, Injy Johnstone, Joseph Stemmler IN: Environmental Research Letters, https://doi.org/10.1088/1748-9326/ad661e

As governments start to devise CDR support policies, this paper solicits the views of market participants in two of the most prominent CDR methods: bioenergy with carbon capture and storage (BECCS) and direct air carbon capture and storage (DACCS). The authors survey 47 BECCS and DACCS project developers and financiers active in Europe, conducting in-depth interviews with 27 of them to identify their key challenges and preferred policy interventions to address them.

Dufour et al. (2024): How to maintain environmental integrity when using state support and the VCM to co-finance BECCS projects – a Swedish case study

Malin Dufour, Kenneth Möllersten, Lars Zetterberg IN: Frontiers in Environmental Science, https://doi.org/10.3389/fenvs.2024.1387138

This paper focuses on the financing of bioenergy with carbon capture and storage (BECCS) in Sweden. A Swedish state support system for BECCS based on results-based payments is planned. Furthermore, demand for CDR-based carbon credits is on the rise on the voluntary carbon markets (VCM) for use towards voluntary mitigation targets. Risks involved with the current Swedish policies are analysed, specifically for the co-financing of BECCS by the planned state support and revenues from the VCM.

Ugarte-Lucas & Jacobsen (2024): Public perception of bioenergy with carbon capture and storage in Denmark: Support or reluctant acceptance?

Paula Ugarte-Lucas, Jette Bredahl Jacobsen IN: International Journal of Greenhouse Gas Control, 136, https://doi.org/10.1016/j.ijggc.2024.104187

Little is known about public support for BECCS. This paper gauges Danes’ willingness to pay (WTP) for biomass with carbon capture and storage and examines factors influencing it, with Denmark as a suitable case study given its reliance on biomass and negative emissions to achieve climate targets.

This study critically evaluates a BECCS-Hub within the North-West Industrial Carbon Capture cluster using advanced digital twin modelling via the Carbon Navigation System and detailed biomass mapping. It investigates five distinct BECCS supply chains at the Protos site, each reflecting novel configurations that closely align with real-life upcoming BECCS projects within the cluster. This research highlights significant carbon performance and scalability variations, crucial for aligning with evolving BECCS business models.

Dong et al. (2024): Negative emission potential from biomass/waste combined heat and power plants integrated with CO2 capture: An approach from the national perspective

Beibei Dong, Shuo Wang, Eva Thorin, Qie Sun, Hailong Li IN: Journal of Cleaner Production, 467, https://doi.org/10.1016/j.jclepro.2024.142917

Integrating carbon dioxide (CO2) capture in biomass or waste-fired combined heat and power (CHP) plants has been considered a key measure to achieve negative emissions. This paper proposed a bottom-up approach based on a dynamic modelling to evaluate the potental of nationwide negative emissions. As heat supply is often prioritized by CHP plants, unchanged heat generation is a prerequisite of this study. Two operating modes (OMs) for the integration of CO2 capture are investigated, which can represent the upper and lower boundaries of CO2 capture: OM1 aims to maximize the amount of captured CO2, while electricity generation can be sacrificed; OM2 aims to maximize the amount of captured CO2, while the electricity generation is maintained unchanged. Sweden is employed as a case study.

Kim et al. (2024): Recent advances in engineering fast-growing cyanobacterial species for enhanced CO2 fixation

David S. Kim, José Ángel Moreno-Cabezuelo, Eduardo Nicolas Schulz, David J. Lea-Smith, Uma Shankar Sagaram IN: Frontiers in Climate, 6, https://doi.org/10.3389/fclim.2024.1412232

In this review, the authors evaluated the thermodynamic considerations of performing atmospheric carbon removal using microalgae and cyanobacteria versus physicochemical processes and explore the implications of these energetic costs on the scalability of each respective solution. They review the biomass productivities of recently discovered fast-growing cyanobacterial strains and discuss the prospects of genetically engineering certain metabolic pathways for channeling the fixed carbon into metabolic ‘carbon sinks’ to further enhance their CO2 capture while concurrently extracting value. The authors share our perspectives on how new highly productive chassis strains combined with advanced flux balance models, essentially coupling synthetic biology with industrial biotechnology, may unlock more favorable methods for CDR, both from an economic and thermodynamic perspective.
