Earth sciences at the centre of the energy transition

Abstract

Achieving a successful energy transition requires society to deploy as many technologies as possible, rather than relying on one single technology to be the ‘magic bullet’. However, there are characteristics that make this transition more challenging than previous transitions in terms of its scope. These challenges include the wide range of sustainable technologies involved and the time constraints. For this research the importance of carbon capture and storage (CCS) and hydrogen technologies for the decarbonization process was analysed, including the main challenges that their large-scale implementation is facing from a subsurface perspective. The ongoing role that fossil fuels play, as well as how the hydrocarbon industry can facilitate the current transition, must also be considered. The common denominator in the analysis is the critical position of Earth sciences in discovering, characterizing, and sustainably utilizing subsurface resources. Geoscientists are essential for providing communication and cooperation between scientists and stakeholders who use, manage and preserve the subsurface. The success of CO2 and hydrogen storage, as part of the climate change mitigation strategies, and the eventual phase-out of fossil fuels ultimately depends on the sustainable development of the subsurface.
