4th DUBROVNIK CONFERENCE ON SUSTAINABLE DEVELOPMENT
OF ENERGY WATER AND ENVIRONMENT SYSTEMS
Special Session: Energy and Water Polygeneration
Session resume: During the last decades the world’s economy has continuously augmented, reaching an average value of 5.1% in 2004, the highest rate recorded during the last three decades. Present world’s population is about 6.5 billion people, experiencing a two fold increase during the last three decades. As a consequence, natural resources demand is continuously growing –it is estimated that during the first two decades of 21st Century, humankind will consume as much natural resources as during the whole 20th Century. The increased usage of natural resources, particularly water and energy, which are limited and essential for the life and for the socio-economic development of societies, are provoking environmental loads endangering the sustainability of life support systems as we know at present. Process integration and polygeneration are promising tools not enough exploited yet, allowing to reach the double objective of increasing the efficiency of natural resources minimizing at the same time their consumption as well as the environmental impact. In this session the concepts of polygeneration and energy integration are discussed and analyzed –e.g. simultaneous sugar, alcohol and energy production; conventional and innovative CHP systems based on ORC and Fuel Cell systems; combined production of water and energy-, showing their feasibility and the dramatic saving of natural resources that can be achieved without reducing the quantity and quality of products and services obtained.

Special Session: Bioethanol in Transport
Session resume: Ethanol produced from agricultural crops is becoming an important alternative for gasoline substitution. Several countries have already legislated to introduce bioethanol in their respective energy matrix. The two most important experiences are Brazil and the USA, although the market will include European and Asian countries. This session’s objective is to discuss the potential for bioethanol production throughout the world and the perspectives for market development for light vehicles. At the Dubrovnik Conference in 2002 Prof Luis Cortez has presented the paper “Worldwide Use of Ethanol: A Contribution for Economic and Environmental Sustainability”. In that article was foreseen the creation of an ethanol market for transport and discussed the possibilities for Brazil to become its major supplier. This session will have the participation of participants from Europe and Latin America presenting their own experiences and views for the future.

Special Session: Hydrogen Fuel Cells for Transportation
Session resume: Hydrogen is a fuel that is by many considered a future solution of the current energy problems. Hydrogen itself is not toxic and its combustion does not create any pollution or greenhouse gases. Hydrogen does not have to be combusted – electrochemical conversion in fuel cells is a very efficient way of using hydrogen to provide useful energy. Hydrogen is a synthetic fuel which can be produced from all and any energy sources including fossil fuels, nuclear energy and renewable energy sources. Hydrogen may be used as fuel in almost any application where fossil fuels are used today – particularly in transportation, where it would offer immediate benefits in terms of reduced pollution and cleaner environment. Almost every car manufacturer has already developed and demonstrated at least one prototype fuel cell vehicle, and some have already went through several iterations / generations of fuel cell vehicles. Fuel cells in transportation offer clean alternative to gasoline and diesel internal combustion engines. For some countries, such as U.S., the ability to generate it’s own fuel is a more important driver for fuel cell vehicles development than low emissions. The main challenges for fuel cell vehicles are the size of hydrogen storage needed for an acceptable range, the cost of the fuel cells, and the cost and logistics of establishing hydrogen infrastructure. Contributions to this session will cover different aspects of fuel cells for transportation, from in-field experience of setting up an infrastructure to run hydrogen vehicles to the visions of future infrastructure, from the details of fuel cell and fuel cell engines development and testing to the critical barriers to the transition towards a hydrogen-centric sustainable energy system.

Special Session: Sustainable Energy and Transportation Systems
Session resume: Around the world e.g. in US, the European Union and China, policies has been formulated with the objective of decreasing CO2 emissions. And in many nations policies to raise the share of renewable energy are being initiated as part of the global response to climate change. A key element in achieving such goals is to use renewable energy in the transportation sector. Several different technologies have been put forward, but in practice no single technology can solve the problem on its own. Lots of different single contributions have to be put together and have to be coordinated with parallel activities with the rest of the energy sector. This session temps to focus on the methodologies and practice in analysing such coherent sustainable energy and transportation systems.

Special Session: Sustainable Socio-technical Transport Systems
Session resume: It seems fair to state that engineers typically do not systematically seek advice from social scientists – or only in an end-of-pipe fashion to advertise 'objectively' superior products to public, corporate or private consumers. The 4th Dubrovnik Conference on Sustainable Development in general, and this session in particular provides a venue where the advantages and shortcomings of this approach can be explored. Contributions to this session offer insights from recent research about the systemic interweavement of the social, institutional and technical aspects of the challenge to achieve more sustainable transport futures.
Dr. Ralf BrandThe University of Manchester, Manchester, UK
Dr. Ralf Brand is championing a co-evolutionary approach to sustainable development, through which social and technical innovations can be aligned. Most of his publications revolve around this idea to synchronise social and technical change and help to understand the socio-technical complexities of attempts to create more sustainable futures – for example his seminal study on the mobility policy in the Belgian city of Hasselt. He holds a Ph.D. In Community and Regional Planning from the University of Texas at Austin and is currently Lecturer in the Manchester Architecture Research Centre.
Special Session: Thermodynamics and the Destruction of Resources
Session resume: This session is focused on the application of thermodynamic thinking to those new areas of study that are concerned with the human use of resources, and the development of a sustainable society. The contributions involving destruction of material/energy resources and ecological impact of manufacturing and other systems and processes would be of interest. Comparing alternatives from the viewpoint of their sustainability requires a systems view that goes beyond the relatively narrow focus of traditional engineering analysis, and considers the entire life cycle, including relevant economic, ecological and societal systems. Since ecosystems are the underlying basis of all economic and societal activities, many methods focus mainly on the impact of human activities on ecological systems. These methods include life cycle assessment, eco-efficiency analysis, and total cost assessment. However, regardless of the methods used, thermodynamic thinking is an underlining discipline in many of these inquiries. The session welcomes papers devoted to this synergy.

Special Session: Scenarios of Sustainable Development
Session resume: Twenty years after the Brundtland commission established the modern definition of sustainable development there are still many open questions. While in theory the concept of sustainability seems clear and well defined, many contemporary challenges are threatening its implementation, such as the global climate change, the need for a transition to renewable energy systems, and the need to implement sustainability principles in all sectors of human activity. Transformation of environmental challenges into economic opportunities could be a possible solution to many of these challenges. Such a solution is however not simple and requires high quality knowledge and skills of many different stakeholders. Some important contemporary challenges to sustainable development and some examples for possible solutions will be presented within the special session on Scenarios of Sustainable Development.
