In the next three decades, there will be significant expansion and repurposing of the global energy infrastructure to deploy a spectrum of new technologies, including renewables, hydrogen, CCS, large-scale storage, bioenergy, EVs as well as enabling infrastructure such as transmission lines.  Companies will invest billions of dollars and will depend on market development, technological progress and government policies for successful implementation.  It will require unparallel partnership among governments, private companies, investors and civil society.  Which technologies are ready for deployment today?  What are the major challenges and risks to build tomorrow’s energy infrastructure? What are the models for successful public and private partnerships? How can permitting be accelerated? How should the people needed to design and build this infrastructure be recruited and trained?
