LNG Deliveries and Their GHG Emissions
Michal Kocůrek
Summary: Methane leakages significantly contribute to emissions of greenhouse gases related to natural gas production and transport from the production wellhead to the final consumer burner tip. In addition, satellite imaging is revealing a much larger extent of methane emissions than indicated by earlier estimates and measurements. Compared with carbon dioxide, methane has a many times greater global warming potential (GWP). Nevertheless, methane release into the air, which occurs within the gas industry, can be relatively easily reduced using the currently available technology. A good motivation for reducing methane leakages is the currently high price of natural gas, and also, progressively, customers’ disinterest in fuels having a high emission footprint.

Coal Phase-out: What Will Replace Coal and with What Emissions?
Matěj Hrubý
Summary: Coal has long been one of the pillars of the Czech energy sector. The importance of coal is also visible in 2021, when it accounted for 38% of electricity generation (15.8 TWh) in the first half of the year. In spite of that, coal burning is expected to be phased out in the Czech Republic by around 2030. The contribution describes, inter alia, the impact of coal burning phase-out on the production of CO2 emissions and discusses the options for replacing coal as a fuel. Together with RES, natural gas appears to be the natural replacement. Despite its fossil nature, natural gas is able to reduce CO2 emissions significantly and to help decarbonise the Czech electricity and heat supply industries.
