CH4 Cracking-Hydrogen viable?
Interesting overview of cracking Methane to produce Hydrogen and Carbon from CH4 that explores the balance between hydrogen production and fugitive CH4 emissions....
In this work, a model exploring the impact of methane cracking implementation in a hydrogen economy is presented, and the impact on global emissions of carbon dioxide and methane is explored. Summary •Methane cracking-hydrogen economy has the potential to mitigate climate change. •Up to 27% global CO2-eq emissions decrease by methane cracking-hydrogen economy. •Strong influence of CH4 leakage from natural gas system on total global emissions.

Methane Cracking-H2 economy ?reduce greenhouse gas emissions
Below is a very brief summary of https://www.sciencedirect.com/scienc...60319916333213 -A study has found that a fossil-fuel-enabled bridge to a fully renewable-based hydrogen economy could help to reduce greenhouse gas emissions. However, the study also found that the impact of this approach on emissions is highly dependent on a number of factors, including the production of hydrogen, the leakage of methane from natural gas production, and the efficiency of hydrogen fuel cells.
The study found that if the globally-averaged methane leakage rates from natural gas production are below 7%, then the Methane Cracking-H2 economy could lead to net CO2-equivalent emissions decreases. However, higher methane leakage rates could lead to an increase in emissions. The study also found that the methane cracking and hydrogen fuel cell technologies needed to achieve net emissions decreases are not yet fully developed. Further research and development is needed to determine the energy conversion efficiency of these technologies and their potential impact on emissions. The study also found that more research is needed to understand the potential environmental consequences of increased shale gas production. For example, increased shale gas production could lead to air quality degradation and drinking water contamination. Overall, the study found that the MC-H2 economy could be a promising way to reduce greenhouse gas emissions. However, further research is needed to fully understand the potential benefits and risks of this approach. read full article: https://www.sciencedirect.com/scienc...60319916333213
