Nature – Impact of declining renewable energy costs on electrification in low-emission scenarios

Gunnar Luderer, Silvia Madeddu, Leon Merfort, Falko Ueckerdt, Michaja Pehl, Robert Pietzcker, Marianna Rottoli, Felix Schreyer, Nico Bauer, Lavinia Baumstark, Christoph Bertram, Alois Dirnaichner, Florian Humpenöder, Antoine Levesque, Alexander Popp, Renato Rodrigues, Jessica Strefler, Elmar Kriegler IN: Nature Energy (2021).

„Here we show that further progress in solar- and wind-power technology along with carbon pricing to reach the Paris Climate targets could make electricity cheaper than carbon-based fuels. […] The lower production of bioenergy in our high-electrification scenarios markedly reduces energy-related land and water requirements.“


Webinar: How Can Carbon Mineralization Help Fight Climate Change?

6 December 12:00 PM to 1:30 PM

by Columbia Center on Global Energy Policy

A new report co-authored by Columbia University scholars finds the climate change benefits of enhancing carbon mineralization processes could be enormous. The ICEF Carbon Mineralization Roadmap explores several strategies, including injecting CO2-rich fluids into underground rock formations and exposing crushed rocks to CO2-rich gases. Please join the Center on Global Energy Policy as several co-authors of the report present their recommendations for using carbon mineralization processes.


Yang et al. (2021): Harmonized comparison of virgin steel production using biomass with carbon capture and storage for negative emissions

Fan Yang, Hans Meerman, André Faaij IN: International Journal of Greenhouse Gas Control 112, 2021,103519,

Mass and energy balances were used to evaluate each route’s cradle-to-gate CO2eq emissions. Results indicate that using either CO2 capture and storage (CCS) or biomass can reduce, but not eliminate, CO2eq emissions in the iron and steel sector. However, the combination of CCS and biomass (BECCS) can result in CO2-neutral or even CO2-negative steelmaking.

LINK COP26 – Key Outcomes From the UN Climate Talks in Glasgow

By Helen Mountford, David Waskow, Lorena Gonzalez, Chirag Gajjar, Nathan Cogswell, Mima Holt, Taryn Fransen, Molly Bergen and Rhys Gerholdt (World Resources Institute)

„Despite significant headway on several fronts, national climate and financing commitments still fell far short of what is needed to come to grips with the climate challenge. Here’s a summary of where things landed at COP26.“


Tatarewicz et al. (2021): The Role of BECCS in Achieving Climate Neutrality in the European Union

Igor Tatarewicz, Michał Lewarski, Sławomir Skwierz, Vitaliy Krupin, Robert Jeszke, Maciej Pyrka, Krystian Szczepanski, Monika Sekuła IN: Energies 2021, 14, 7842.

This research is devoted to an analysis of BECCS as a negative emissions technology (NET) and the assessment of its implementation impact upon the possibility of achieving EU climate goals by 2050.


Latest Special Issue: CO2 Utilization Technologies

Oxford University Press; Clean Energy Volume 5, Issue 4 (December 2021); ISSN 2515-4230

In a new special issue, authors discuss new CO2 -utilization technologies at various stages of development and commercialization. These technologies have the potential to provide opportunities for emission savings for power and other industrial sectors by partially substituting fossil-fuel raw materials, increasing efficiency and reducing GHG emissions, and generating revenues through producing marketable products.


Migo-Sumagan et al. (2021): A Superstructure Model for Integrated Deployment of Negative Emissions Technologies under Resource Constraints

Maria Victoria Migo-Sumagang, Kathleen B. Aviso, John Frederick D. Tapia, Raymond R. Tan IN: Chemical Engineering Transactions, 88, 31-36 DOI:10.3303/CET2188005

In this work, a superstructure-based Linear Programming (LP) model is developed to optimize the carbon drawdown of integrated NET deployment under resource constraints. Results show that varying the target negative emissions and resource constraints affect the NETs portfolio and total cost.


Nature – Jordaan & Wang (2021): Electrocatalytic conversion of carbon dioxide for the Paris goals

Sarah M. Jordaan & Chao Wang (2021) IN: Nature Catalysis Vol. 4 (Issue 11); 915–920;

Electrocatalytic conversion of CO2 into useful products can contribute to the Paris goals on the basis of abundant low-carbon power and technological advances. From R&D to policy, areas are highlighted in which coordinated efforts can support commercialization of such capture and catalytic technologies while deploying the required infrastructure.
