Mitigating climate change and ensuring energy security demand cost-effective energy solutions, particularly for large-scale integration of renewable energy sources (RES) to the electricity grid and the removal of CO2 from fossil-fuel power plants. Nanostructures hold the key to such solutions. Clear understanding of “energy-carrier” interactions with host structures is essential to design efficient energy storage systems (hydrogen and batteries), CO2 sorbents in carbon capture and photo-catalysts in solar harvesting. Fundamental simulations are important in probing the specific mechanisms of binding, activation and sorption of gaseous molecules in representative host structures for the design of efficient hydrogen/charge storage systems, as well as sorbents for CO2. Particular attention is focused on the simulation-guided design, synthesis and characterization of graphene/carbon- d nanostructures, with controlled hierarchical porosities, for the storage of energy carriers and capture of CO2, where surface chemistry, texture, defects, dopants and ligand molecules play important roles in carrier sorption, storage, and transport. Different design and synthesis routes will be comparatively assessed for the effective development of practical systems. Important avenues for further study are discussed to speed up the development of clean energy technologies.
