Objectives The purpose of this proposal is to explore novel, potentially lower-cost materials, which would offer the capability of high volumetric storage of hydrogen.
Abstract It is now widely recognised that a hydrogen-based energy economy may prove to be the best long-term solution to the problems of global warming, security of fuel supply, oil depletion and inner-city pollution. Ideally, hydrogen will primarily be produced by the electrolysis of water using a range of renewable energies. As many of these sources are intermittent (wind, solar, etc), energy storage is a critical issue and hydrogen storage could be one solution. Additionally, as part of the hydrogensupply infrastructure, it will be necessary to store hydrogen on location for a range of applications; for example, vehicular fuelling stations and local/ district energy centres. The alternatives for hydrogen storage are compressed gas cylinders, liquid hydrogen or solid-state stores. However, there are safety and security issues associated with compression and liquefaction, which may favour the use of solid-state storage (typically a low pressure technique) in densely populated, urban areas. The current method of solid-state storage employs metal hydrides (eg LaNi5) that have volumetric storage densities higher than those of compressed gas cylinders or liquid hydrogen. However, on a large scale, such materials would represent a major capital investment, and so there is a need for much cheaper and widely available materials for hydrogen storage. This project has: (i) undertaken a review of the hydrogen fuelling station projects around the world, to assess the various technical requirements for the on-site storage of hydrogen; (ii) studied the basic hydrogen sorption properties of potentially low-cost materials, such as carbons and zeolites. Materials synthesis techniques include High Velocity Ball Milling, with a specially designed milling pot which allows pressure to be monitored during milling (inset photograph). Characterization techniques include the use of a constant pressure Thermogravimetric Analyser (Hiden IGA), which enables the hydrogen uptake and sorption kinetics of different processed materials to be assessed
