The increase has accelerated in recent years, and preliminary data indicate that there was another significant annual increase in 2022.. Estimates of methane emissions are subject to a high degree of uncertainty, but the most recent comprehensive . Methane is a relatively less toxic, but highly inflammable and explosive gas. The toxicity with respect to methane is correlative with its attributes such as flammability, explosiveness, and low ignition point. . (Table 18.2) and analytical hierarchy process are the two excellent methods for the quantitative analysis of methane-related risk .
Methane pyrolysis technology can produce low-cost, low-emission hydrogen. . The analysis indicates that the most prominent barriers to methane pyrolysis are trelated to the challenges under high-temperature and high-pressure operation, as well as corrosive reaction environments. These challenges will require additional research and investment .
