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 10: Hydrogen from Renewables

Dries Haeseldonckx and William D’haeseleer


Dries Haeseldonckx and William D’haeseleer INTRODUCTION At the start of the twenty-first century, we face significant energy challenges. An important aspect of sustainable development is ‘de-fossilizing’ our future energy economy. This mitigation from fossil fuels towards more sustainable energy technologies is driven by several factors: ● ● ● ● The need for a drastic reduction of CO2 emissions, that is, 20 percent reduction of greenhouse gases (GHGs) by 2020 as proposed by the EU Commission (2007). The worldwide energy-dependence issue; fossil fuels alone will not suffice, moreover differentiation in primary energy sources will improve the security of supply. The exhaustibility of fossil sources; at current consumption and production levels, the world’s proven reserves of oil, natural gas and coal are expected to be ‘depleted’ in 42, 64 and 155 years, respectively (IEA, 2006). Although these ‘years left’ are moving targets, prices will rise substantially when oil fields become more depleted. The needs of developing economies; it might be fair to leave the ‘easy sources’ for them. The substitution of fossil fuels by renewable energy sources is a mitigation strategy that is advocated by non-governmental organizations, some research institutes and groups of stakeholders, and can be found in concrete policy goals. The future use of renewables is now accepted by almost every energy analyst; only the level of penetration is currently a matter for discussion. The main modern renewable energy technologies that produce electricity are small hydropower, solar photovoltaics, concentrating solar power, biomass, geothermal power and wind energy (IEA, 2003). Nevertheless, despite being clean and...
