Critically exploring the future of gaseous energy carriers

Abstract

Opinions are divided if natural gas is a boon or bane in the context of climate change mitigation. This article explores the arguments around what role this fuel, and so called “green gas” will play in a future energy mix. The analysis splits the natural gas resource from the associated infrastructure, and argues that the pipeline infrastructure may have an important role to play in the transition. Green gas has emerged as a solution that may play an important role in the future, provided costs can be reduced further. Both “green” and “blue” hydrogen, as well as biomethane are explored in this context. Relatively little analysis and exploration has been focused on the midstream infrastructure aspect, as opposed to the focus on the fuels use in the power generation or, for example, home heating. Much will depend on future technical issues, but just as importantly in the regulatory and policy space, and interactions with society and the environment.
