At IEA Clean Coal Centre webinars our expert authors give presentations on the findings of their latest reports. Webinars usually take place on the second Wednesday of the month at midday (UK Time). If you are unable to attend the event live, they can be viewed at any time after the event from this page.
Climate implications of coal-to-gas substitution in power generation, is the subject for the next webinar, which will be presented by Herminé Nalbandian on Wednesday 18 February at midday (UK time).
Coal is the most widely used primary energy source in power generation, with 36% share in 2014 of electricity generated globally. There is currently a trend of substituting coal with natural gas in some parts of the world. Natural gas combustion produces about half the greenhouse gases compared to coal. However, in recent years, several studies considered the implications of methane emissions on climate change in large scale switching from coal to gas for electricity generation. Methane is a hydrocarbon and the primary component of natural gas. It is more potent than carbon dioxide as a greenhouse gas, and therefore is a significant contributor to climate change, especially in the near term (10–20 years). The studies have found that methane emissions from gas exploration, extraction, transmission and distribution, unless controlled, could make the benefits of coal to gas substitution, questionable, especially so in the short term. This webinar reviews these publications and their findings.
