Security of Energy Supply in Europe

Natural Gas, Nuclear and Hydrogen

Edited by François Lévêque, Jean-Michel Glachant, Julián Barquín, Christian von Hirschhausen, Franziska Holz and William J. Nuttall

In economic, technical and political terms, the security of energy supply is of the utmost importance for Europe. Alongside competition and sustainability, supply security represents a cornerstone of the EU’s energy policy, and in times of rising geopolitical conflict plays an increasingly important role in its external relations. Within this context, the contributors analyse and explore the natural gas, nuclear, and hydrogen energy sectors, which will be of critical significance for the future of energy supplies in Europe.

Chapter 9: Supply Security and Hydrogen

Julián Barquín and Ignacio Pérez-Arriaga


Julián Barquín and Ignacio Pérez-Arriaga INTRODUCTION Today’s energy systems are based on the use of fossil fuels, which presently provide for about 80 percent of the total world energy needs (IEA, 2007a). As a consequence, the energy system is both unsustainable and prone to security of supply concerns. Indeed, fossil fuel combustion is thought to be the main cause of climate change (IPPC, 2007). Furthermore, Europe is highly dependent on imported fossil fuels, and in particular on oil and natural gas, from sources not always reliable. The ultimate amount of reserves is also uncertain, although substantial depletion of oil is expected before mid-century (IEA, 2007b). Most likely, any solution will require the use of a wide portfolio of technological and policy options. Hydrogen technologies have been proposed as a part of this portfolio, potentially addressing two important issues: storage of energy from intermittent energy sources and provision of an alternative fuel for transportation (Sherif et al., 2005). This chapter is mainly based on the CESSA conference ‘Prospects for a European Hydrogen Economy’ presentations and discussions. The conference was held in Madrid, April 14–15, 2008. However, the authors are exclusively responsible for its content. The rest of the chapter is organized as follows. The next section discusses the reasons that support the development of hydrogen technologies. Sections 3, 4 and 5 focus, respectively, on hydrogen production, infrastructure development and final use. Section 6 deals with research and development issues. Finally, Section 7 concludes. 2 WHY A HYDROGEN...
