Role of Natural Gas in the Czech Energy Transition as Related to Coal Phase-out

Pavel Liedermann

Summary: The author’s ambition is to outline for the readers the significant changes in power generating capacities, which can be expected over the coming 20 or so years. The requirements for reducing the environmental impacts caused by power generation will pressure for changes in power stations’ generating technology. An equivalent substitute for coal burning, which will be phased out, is not yet available. Natural gas can therefore serve as a tool for partial decarbonisation, although on a temporary basis only. Natural gas can be expected to be used in many segments of the energy sector, including power generation, heat production on cogeneration, and balancing services.

LNG Prospects in Broader Contexts

Jan Bezděkovský

Summary: The article deals with the challenges facing not only the Czech but also the European LNG vehicle market in connection with the current and forthcoming EU regulation, offering a critical look at the environmental benefits of natural gas in transport. It thus points to some of the questions that are being raised against natural gas, mainly by environmental organisations, given that such arguments are winning more and more of EU institutions’ attention. The author’s objective is to stimulate further technical discussion on the topic rather than answering the question of whether the vision of LNG mobility development contained in the National Action Plan for Clean Mobility is meaningful in the context of current climate change challenges.

Methane Decomposition to Produce Hydrogen

Milan Bernauer, Vlastimil Fíla, Bohumil Bernauer

Summary: The growing interest in hydrogen and hydrogen management has raised the question of how to use hydrogen resources efficiently and how to transform them as efficiently as possible into higher value-added components. The production of hydrogen by existing technologies has so far focused on the highest possible yield of hydrogen and the optimisation of these production processes. However, emissions of by-products (in particular CO2) remain a major issue constituting an increasingly important environmental problem. In the future, new processes for producing hydrogen from natural gas (methane) may also focus on the synergistic production of hydrogen and carbon products in the form of carbon black or various forms of carbon nanofibres. The presented overview of hydrogen synthesis includes both conventional and traditional processes and primarily a new approach to the production of hydrogen from methane and hydrocarbons in general via their direct decomposition, i.e. pyrolysis.
