Energy Matters: Catalysis for Chemical Hydrogen Storage

To promote innovations toward solving energy and environmental problems that are expanding on a global scale today is a difficult challenge for scientists and engineers. Much effort is needed to develop technologies that reduce CO2 emissions and help to overcome the present society depending on fossil fuels as primary energy. Hydrogen has attracted increasing attention as an alternative secondary energy resource, because the reaction of hydrogen with oxygen produces the requested energy and only water as by-product. However, storage and transportation of hydrogen is a difficult issue. Chemistry offers a convenient solution to this problem, by converting it to chemical substances such as NH3, NH3-BH3, methylcyclohexane, and LOHC (Liquid Organic Hydrogen Carriers) such as formic acid (FA). FA has been considered to be a promising substance for the chemical hydrogen storage because it is a non-toxic, environmentally friendly liquid containing 4.4 wt% H2. It is also advantageous that CO2, a substrate to produce a FA, is inexpensive and ubiquitous. This research line aims to offer new possibilities to overcome the energetic problem by using metal-based catalysts for hydrogen storage as a tool. We are looking for talented researchers interested in developing materials for energy efficiency and renewable energy applications based on transition-metal complexes or chemistry.
