Knowledge Gaps

Physical science / mechanism

Version published: 
  • The field of methane removal is very nascent and there are many open science questions. These knowledge gaps also differ by approach. Some of these from Spark Climate Solutions’ Atmospheric Methane Primer include:
    • How do different radicals affect methane oxidation?
    • Can we develop greater precision over time and space of methane sinks?
    • How would abatement or emissions growth of a given reactive gas (e.g., carbon monoxide, hydrogen) impact methane oxidation rates and atmospheric lifetime, and the lifetime and effects of other gasses?
    • What are more accurate baselines and trajectories for diffuse sources of methane?
    • How might we develop better predictive capabilities for the state and timelines of tipping elements and other non-linear behaviors in natural methane sources?
    • How can we better constrain our understanding of methane sources?

Engineering needs (technical feasibility)

Version published: 
  • The field of methane removal is very nascent and there are many open science questions. These knowledge gaps also differ by approach. Some of these from Spark Climate Solutions’ Atmospheric Methane Primer include:
    • Can improved sensors be developed for in situ atmospheric, aquatic, and terrestrial monitoring?
    • Development of bio-engineering for methanotrophy enhancement.
    • How can catalytic efficiency for reactors and surface treatments be improved?
    • Can more efficient airflow systems for reactors be developed?
    • Development of mechanisms for particle generation and dispersal for atmospheric oxidation enhancement approaches.
