Master thesis: Combating Global Warming: Modeling Enhanced Rock Weatheringof Wollastonite Using Density Functional Theoryof Wollastonite Using Density Functional Theory

Luan, Brian (2022) Thesis. Rochester Institute of Technology. 88 pp.; accessed from RIT Scholar Works

To obtain an atomic scale understanding of the weathering process and to design more reactive silicates for enhanced rock weathering, CO2 adsorption on low Miller index wollastonite (CaSiO3) surfaces was modeled using density functional theory. Atomic scale structure of (100), (010), and (001) surfaces of wollastonite was predicted and the thermodynamics of their interaction with CO2 was modeled. Mechanisms for electronic charge transfer between the adsorbate and the substrate were studied to shed light on the fundamental aspects of these interactions.

Certification of Carbon Removals: Part 1: Synoptic review of carbon removal solutions

Niki Bey, Hugh McDonald, Larisa Maya-Drysdale, Raphaëlle Stewart, Cordelia Pätz, Maria Naae Hornsleth, Laurens Duin, Ana Frelih-Larsen, Christian Heller, Paul Zakkour; report, 126 pp. owner and editor: Environment Agency Austria

The European Commission is developing a certification mechanism for naturebased and technology-based carbon removals. To support its development, this report aims to provide a thorough overview and reviews existing solutions for such removals, covering both nature-based solutions (NBS) and technology-based solutions (TBS). By documenting different key characteristics, the report identifies and evaluates a range of options for the EU certification mechanism, supporting the development of a robust and effective system to incentivise uptake of carbon removals within Europe.

NASEM Report (2022): A Research Strategy for Ocean-based Carbon Dioxide Removal and Sequestration

Consensus Study report; National Academies of Sciences, Engineering, and Medicine.2022, Washington, DC: The National Academies Press. https://doi.org/10.17226/26278, 308 pp.

NOW PRINTED!

This report builds on previous work from the National Academies to assess what is currently known about the benefits, risks, and potential for responsible scale-up of six specific ocean-based CDR strategies as identified by the sponsor, ClimateWorks Foundation. It describes the research needed to advance understanding of those approaches and address knowledge gaps. The resulting research agenda is meant to provide an improved and unbiased knowledge base for the public, stakeholders, and policymakers to make informed decisions on the next steps for ocean CDR, as part of a larger climate mitigation strategy; it is not meant to lock in or advocate for any particular approach.

IAE report: Direct Air Capture – A key technology for net zero

by International Energy Agency (76 pp.)

This report explores the growing momentum behind direct air capture, together with the opportunities and challenges for scaling up the deployment of direct air capture technologies consistent with net zero goals. It considers the current status of these technologies, their potential for cost reductions, their future energy needs, and the optimal locations for direct air capture facilities. Finally, the report identifies the key drivers for direct air capture investment and priorities for policy action.

IPCC-report (AR6 WGIII) Climate Change 2022: Mitigation of Climate Change

The IPCC published the third part of the Sixth Assessment Report, Climate Change 2022: Mitigation of Climate Change, the Working Group III contribution. It was finalized on 4 April during the 14th Session of Working Group III and 56th Session of the IPCC. The Working Group III report provides an updated global assessment of climate change mitigation progress and pledges, and examines the sources of global emissions. It explains developments in emission reduction and mitigation efforts, assessing the impact of national climate pledges in relation to long-term emissions goals.

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.

World Energy Transitions Outlook 2022

by the International Renewable Energy Agency (IRENA)

This second edition of the Outlook outlines priority areas and actions based on available technologies that must be realised by 2030 to achieve net zero emissions by mid-century. By laying out a map for the next eight years, the report enables policy makers to stay on the path to 2050. It provides in-depth analysis of two areas particularly relevant for the decarbonisation of end-use sectors: electrification and bioenergy. It also explores the socio-economic impacts of the 1.5°C pathway and suggests ways to speed progress towards universal access to clean energy.
