The study analyses the development and use of hydrogen and the concomitant need for CCUS to provide low-carbon energy sources. In undertaking the analysis, this study critically examines the legal and policy challenges, as well as the opportunities, the hydrocarbon industry will face as states seek to attain their goal of net-zero carbon emissions. The paper undertakes a detailed examination of what the challenges are, how they can be overcome, and the implications for the hydrocarbon industry.
