A review of the critical role geoscience plays in the Energy transition. As the world strives to cut carbon emissions, and meet Net Zero targets, what is the scale of the challenge and how will geologists be called upon to meet that challenge. From securing gas as a replacement fuel and delivering energy security to the developing world. Carbon sequestration to mitigate the impact on climate change and offer carbon neutral hydrocarbons. Critical minerals. And geologists role in future geothermal and other subsurface renewable resources.
