Energy and environmental security are truly major problems facing our global economy. Fossil fuels, particularly crude oil, are confined to a few regions of the world and the continuity of supply is governed by dynamic political, economic and ecological factors. These factors conspire to force volatile, often high fossil fuel prices while, at the same time, our environmental policies are demanding a reduction in greenhouse gases and toxic emissions. Thus a coherent energy strategy is required, addressing both energy supply and demand, taking account of the whole energy lifecycle including fuel production, transmission and distribution, and energy conversion, and the impact on energy equipment manufacturers and the end-users of energy systems. In the short term, our aim should be to achieve higher energy efficiency and increased energy supply from local energy sources, in particular renewable energy sources. In the long term, a hydrogen-based economy will have an impact on all these sectors. In view of technological developments, vehicle and component manufacturers, transport providers, the energy industry, and even householders are seriously looking at alternative energy sources and fuels and more efficient and cleaner technologies – especially hydrogen and hydrogen-powered fuel cells.
