Take part in the emerging scientific discussion on methane removal research, and learn from leading scientists as we explore the challenges and opportunities of this new research area.
Join Spark Climate Solutions for monthly webinars, as we host scientists from around the world to discuss their research and explore challenges and opportunities associated with methane removal research.
Methane removal is an emerging area of climate research with potential to be part of a portfolio approach for addressing climate risks. Methane is a short-lived, powerful greenhouse gas characterized by diverse anthropogenic sources, strong radiative forcing, increasing atmospheric concentration, and a risk of growing emissions from natural sources. Potential atmospheric methane removal approaches are being explored to accelerate natural methane breakdown processes. All approaches are at an early stage, and much more research is needed to understand how, and if, methane removal may be a feasible, safe, and acceptable addition to the climate response portfolio.

Methane removal approaches are still in early stages of research, and consideration of the legal frameworks that could apply to field testing and any future potential deployment is critical for responsible governance. Which national and international laws come into play vary significantly based on the approach and the location where field tests or deployment may be considered in the future; atmospheric oxidation enhancement in particular presents a challenge of intersecting juridictions and types of risks. As more is known about approaches, legal frameworks must proactively evolve as well.
Join the Spark monthly methane removal webinar for a conversation with Romany Webb and Korey Silverman-Roati of the Columbia Sabin Center for Climate Change Law about their analysis of the current legal frameworks for atmospheric oxidation enhancement and soil amendments, and their perspectives on how to build a responsible legal foundation for methane removal governance starting now.

Removal of methane from the atmosphere using reactor systems is an emerging area of research, which may use surface-based catalysts, gas-phase radicals, or microbes to break down or consume methane flowing through them. Reactor technologies are already being applied to address dilute methane emission sources, such as dairy barns or coal mines; what would it take for reactors to have efficacy at atmospheric methane concentrations (2 ppm) and climate-relevant scale? Are there possible technologies to add methane removal capacity to direct air capture (DAC) capacity?
Spark hosted Prof. Lisa Stein (University of Alberta), Prof. Adam Boies (Stanford University), and Prof. Matthew Johnson (University of Copenhagen) to discuss the potential of reactors for atmospheric methane removal. They each have different approaches to this challenge, Prof. Stein researches bioreactors, Prof. Boies investigates catalysis and the challenge of accessing airflow at scale, and Prof. Johnson is developing gas-phase radical reactors. Watch to learn more about explore the science, engineering, and feasibility of reactor-based methane removal for meaningful climate impact.

Atmospheric oxidation enhancement (AOE) has been proposed as a pathway to remove excess atmospheric methane, but it is challenging to assess scenarios where these strategies could be effective and safe. What approaches might be worth considering? How can we improve the models used to evaluate them?
Spark hosted Dr. Jessica Haskins (University of Utah) and Dr. Hannah Horowitz (University of Illinois Urbana-Champaign) to discuss atmospheric oxidation enhancement and what research is needed to investigate if there may be a pathway to safe and acceptable use for these methods. Jessica is the co-author of a recent paper highlighting potential air quality side-effects of emitting hydrogen peroxide to enhance methane oxidation, and Hannah is the author of an analysis of several AOE approaches (preprint) commissioned by the National Academies committee that prepared a Research Agenda Toward Atmospheric Methane Removal.

Homeworld Collective’s co-founder and Founding Scientist, Paul Reginato, PhD, discusses the outcomes of a November 2024 Workshop on Biological Methane Removal. This workshop, co-hosted by Homeworld Collective and Spark Climate Solutions, brought together over 40 interdisciplinary experts to identify critical problems constraining the field of biological methane removal and express them in problem statements. The webinar covered high-level scientific themes and research needs emerging from the workshop and lessons learned from this innovative workshop format.
