China’s coal, mined locally and available at a relatively low cost, has brought enormous benefits to energy consumers in China and to those outside the country who enjoy the products of its coal-based economy. Yet from another perspective, China’s coal use has a high cost. Despite progress, health and safety in the thousands of small coal mines lag far behind the standards achieved in China’s modern, large mines. Environmental degradation is a real and pressing problem at all stages of coal production, supply and use. Adding to these burdens, emissions of carbon dioxide are of concern to the Chinese government as it embarks on its own climate protection strategy. Technology solutions are already transforming the way coal is used in China and elsewhere. This study explores the context in which the development and deployment of these technologies can be accelerated. Providing a large amount of new data, it describes in detail the situation in China as well as the experiences of other countries in making coal cleaner. Above all, the report calls for much greater levels of collaboration – existing bi-lateral and multi-lateral co-operation with China on coal is found lacking. China’s growing openness presents many commercial opportunities. Establishing a global market for cleaner coal technologies is key to unlocking the potential of technology – one of ten major recommendations made in this study.

Hydrogen and fuel cells are vital technologies to ensure a secure and CO2-free energy future. This book draws primarily upon information contributed by IEA governments. In virtually all the IEA countries, important R&D and policy efforts on hydrogen and fuel cells are in place and expanding. Some are fully-integrated, government-funded programs, some are a key element in an overall strategy spread among multiple public and private efforts. The large amount of information provided in this publication reflects the vast array of technologies and logistics required to build the “hydrogen economy”.

Which alternative motor fuels will be in common use tomorrow? Which criteria should be used to assess them? No simple answers exist. Complex trade-offs are involved in the decision-making process. But the most important ingredient for making informed choices is sound information produced by a transparent methodology. Automotive Fuels for the Future offers a digest of basic data on the critical fuel choices for the future. It is a well-balanced compendium of concise technical information, as well as an overview of the essential issues in deciding among alternative fuels. Fuels such as natural gas, LPG or alcohols and biodiesel derived from different feedstocks are considered over the entire cycle from production to use. They are analysed in terms of environmental effects, safety, availability and cost. Their weaknesses and strengths are judged against the yardsticks of established gasoline and diesel technologies. This publication from IEA/AFIS, the information service of the IEA Implementing Agreement on Advanced Motor Fuels, makes this information accessible to the general reader.

Hydrogen has the potential to play an important role as a sustainable and environmentally acceptable energy source in the 21st century. However, hydrogen does not exist as a gas on earth and thus has to be produced from, for example, water or natural gas by different separation techniques. One way to do so would be to use nuclear-produced energy or heat in this separation process. The present publication gives an overview of the advancements in the scientific and technological fields related to the nuclear production of hydrogen.

Biofuels received USD 15 billion in subsidies in OECD Member countries in 2007, but did they deliver benefits in terms of climate change or oil security? Present policies make no link between support for biofuels and their environmental performance, and biofuels do not all perform equally well. In fact, much of the current ethanol and biodiesel production may result in higher overall emissions of greenhouse gases than using conventional transport fuels - gasoline and diesel. The papers published in this report examine the economics of biofuels and assess the potential of conventional biofuel production in OECD countries, Brazilian ethanol exports and some second generation biofuels to supply world markets with transport fuels. This Round Table analyses the critical issues for governments in determining support for biofuels, particularly the level of greenhouse gas emissions throughout the life-cycle of these fuels and the wider environmental impacts of farming biomass. It also reviews recent progress in developing certification systems for biofuels – an essential  tool for tying support  to achievement in reducing greenhouse gas emissions, although certification cannot be expected to prevent rainforest destruction for the  development of  biofuel crop plantations. The report concludes with a short list of recommendations for policy reform if support for biofuels is to contribute effectively to mitigating greenhouse gas emissions.
