The present paper gives a general perspective of the efforts going on at Terceira Island in Azores, Portugal, concerning the implementation of an Hydrogen Economy demonstration campus. The major motivation for such a geographical location choice was the abundance of renewable resources like wind, sea waves and geothermal enthalpy, which are of fundamental importance for the demonstration of renewable hydrogen economy sustainability. Three main campus will be implemented: one at Cume Hill, where the majority of renewable hydrogen production will take place using the wind as the primary energy source, a second one at Angra do Heroismo Industrial park, where a cogen electrical heat power station will be installed, mainly to feed a Municipal Solid Waste processing plant and a third one, the Praia da Vitoria Hydrogenopolis, where several final consumer demonstrators will be installed both for public awareness and intensive study of economic sustainability and optimization. Some of these units are already under construction, particularly the renewable hydrogen generation facilities.

Hydrogen generation rate is one of the most important parameters which must be considered for the development of engineering solutions in the field of hydrogen energy applications. In this paper, the kinetics of hydrogen generation from oxidation of hydrogenated porous silicon nanopowders in water are analyzed in detail. The splitting of the Si-H bonds of the nanopowders and water molecules during the oxidation reaction results in powerful hydrogen generation. The described technology is shown to be perfectly tunable and allows us to manage the kinetics by: (i) varying size distribution and porosity of silicon nanoparticles; (ii) chemical composition of oxidizing solutions; (iii) ambient temperature. In particular, hydrogen release below 0 °C is one of the significant advantages of such a technological way of performing hydrogen generation.

In recent years, with the intensification of environmental damage, mankind is at a crossroads towards the next energy revolution. Hydrogen energy, because of its pollution-free nature, has become the focus of technological research and development in many countries, and the economic pattern around it is taking shape China’s investment in the field of new energy has been increasing in recent years, and the prospect of hydrogen economy has prompted China to continuously increase the development of hydrogen energy. However, it faces many obstacles, both technical and social. The Chinese government is now using financial subsidies to help hydrogen companies incubate. However, with the development of the industry, China is currently facing great obstacles in large-scale commercial application, intellectual property protection and innovation, standardization construction and social confidence. This paper believes that policy measures such as selective commercial distribution, innovation system building, industry standardization construction and social education can be adopted to help solve these challenges

Global Strategies

The strong performance of Singapore's chemical industry in recent years has increased public awareness about the importance of this obscure sector in the Singapore economy. In the public rhetoric, much of this robust growth is attributed to the industrial policies implemented by the Singapore government. However, the ultimate decision to built a multibillion dollar chemical-processing plant in resource-scarce Singapore still depends very much on the global strategies of transnational chemical firms (CTNCs). The authors propose a firm-level perspective to aid in understanding the development of Singapore's chemical industry. They argue that the global strategies of CTNCs have a vital role to play in promoting growth within the Singapore chemical industry cluster. Conceived under the 1991 Strategic Economic Plan, the idea of clustering represents a radically different approach to the development of the petroleum-refining, petrochemicals, specialty chemicals, and pharmaceutical industries where previously each was deemed a separate activity. Based on field research into over forty subsidiaries and local suppliers of CTNCs in Singapore, the authors highlight the importance of two major contextual influences on the global strategies of CTNCs: rising global competition and the huge market potential offered by developing countries. Given these circumstances, CTNCs have relied on their established capabilities to formulate spatial strategies for increasing global competitiveness. In Singapore, subsidiaries of CTNCs have tapped into cluster-based advantages to enhance their capabilities, thereby contributing to the further growth of Singapore's chemical industry cluster.

High Energy Storage Density

Transportation accounts for more than a quarter of total global energy consumption. For fuelling road transportation there has been much speculation about the use of hydrogen as an energy carrier, which proponents claim would usher in the “Hydrogen Economy”. The concept of the “complete energy conversion chain” has been used to compare the overall energy consumption and CO2 emissions from vehicles powered by hydrogen fuel cells with those from vehicles using a battery and electric drive. The analysis shows that if a sustainable source of electricity is used to produce hydrogen, then the hydrogen and fuel cell system is just equivalent to a battery. The efficiency of these two different approaches has been compared, and shows that the hydrogen system would consume nearly three times the primary energy required by a battery storage system. Conventional batteries do not, however, have a sufficiently high energy storage density to provide the range needed for most drivers. A new generation of plug-in hybrid vehicles is being developed which take advantage of the best attributes of both electric vehicles and conventional fossilfuelled vehicles. These vehicles show promise to dramatically reduce the quantity of greenhouse gases produced each year by the transportation sector.
