The use of carbon composites in commercial ferries – a case of radical eco-innovation
Sun / 21.09. @ 17:30

This presentation shows how a radically new technology can be developed. The case focus on small  island ferries in European waters using new advances materials. Through a case study based on interviews and action research this presentation deals with displacement ferries where a radical innovation is made in the shift from steel designs to a lighter carbon-fiber composite alternative. A key characteristic for eco-innovation is that it combines techniques, practices, and knowledge across existing boundaries. Networking and collaboration therefore become important for creating ideas and implementing these in order to get the environmental innovations on the market. In this case the ideas originate from the actor’s experiences in other sectors: yacht racing and naval operations. The case shows how new, small, and even competing actors on the market create a radical innovation and build a network to support the solution and the actors’ disruptive penetration of a new market that challenges existing technologies. The environmental improvement potential for small ferries is large as the carbon footprint of a ferry’s total impact can be reduced by 50 per cent by switching from heavy steel constructions to lighter carbon composite alternatives. The main environmental savings are related to smaller engines requiring less fuel.

LCA-Based Multiobjective Synthesis of Sustainable Systems
Mon / 22.09. @ 17:30

Our global system is currently facing severe financial, production, social, and environmental problems. Sustainable development in general, sustainable process industries and their related sustainable systems in particular, are of paramount importance for this reason and due to the very high consumptions of energy in chemical and process industries where only separation processes alone represent about 15% or even 25% of total world energy consumption. Based on the above-mentioned incentives, the driving force is a holistic Process System Engineering approach to the synthesis and designing of sustainable chemical, process, and energy supply-chain networks.

A general mathematical programming framework for the sustainable synthesis will be presented. It consists of applying i) a simultaneous approach in order to exploit complex interactions so that individual subsystems' operations would be adjusted from the system overall performance viewpoint, ii) a multi-objective optimization (MOO) approach using appropriate optimization criteria, and iii) implementation of efficient solution strategies. The advantages and weaknesses of different sustainability measurements - footprints, LCA indexes, and eco-cost applied within MOO will be discussed. The need of upgrading these measurements in order to consider also unburdening effects on the environment, besides the usual burdening ones, will also be discussed. Based on newly defined criteria - total footprints, total LCA indexes, and eco-profit economically efficient solutions can be obtained, where unburdening alternatives have priority over environmentally benign ones.

The synthesis framework will be illustrated on different bioproducts supply chains: i) the total footprints on bioethanol production from different raw-materials, ii) the total LCA index on supply-demand regional biomass network, and iii) the concept of eco-profit on biogas production from different raw materials under different anaerobic conditions. Furthermore, the application of the generic multi-period model for efficient synthesis of biorefinery supply networks for the production of biofuels at the continental level will be presented.

Why Cities will have the Key Role in 100% Renewable Power Systems
Tue / 23.09. @ 17:30

Changing energy supplies towards 100% renewable power resources is no longer a question of whether it is possible or not to achieve the aim. But the question is how to reach the aim to an affordable cost and how to reach the aim to obtain a reliable energy system.

The presentation will explain the necessities for balancing fluctuating renewable resources and by which means this can be done. The alternatives are compared to each other and the conclusion drawn will lead to the hypothesis that cities with their already existing energy infrastructure have the prerequisites to fulfil the demands on a least cost basis.

Especially electricity supplies are demanding as in nowadays systems energy storage is negligible. Pure electricity storages are analyzed and compared to other storage options as heat storage and gas storages which could be accesses when coupling different energy sectors.

The presentation will cover the topics of energy storage, smart girds and smart systems, and rivers as energy sources.

Thu / 25.09. @ 17:30

Water is a basic ingredient of life and a fundamental human right. It is a shared resource on which life, the environment and most human activities depends. Water is also a threat to life and livelihoods. Too much water produces disastrous flood, too little awful drought. Yet pressures on water resources are mounting. We are dealing with a hydro-climatic problem with the potential to destroy ecosystems and parts of economy, and exacerbate poverty as well as inequalities and tensions among and between nations. Planetary water resources are significantly affected by global change, which involves more than climate change. The major drivers of global change are: population growth, climate change and/or variability, uncontrolled and unsustainable urbanization and industrialization, expansion of infrastructure, land use change, massive pollution, unsustainable water resources management, massive deforestation, wetland drying up and many other reasons. Achieving global water security for all is an enormous challenge. The global change is the main reasons for necessity of interdisciplinary scientific co-operation in their management and protection. Protection and sustainable management of the water resources is of crucial importance. It is necessary to take the complex, interactive, technical, social, economic, environmental and cultural aspects of global water resources management into account in decision-making. Of special importance is the establishment of firm network of contacts with leading independent scientists, who promote new ideas and concepts independently of mainstream directions. Transfer of information across spatial and temporal scales is one of the most fundamental issues in the water hazard and risk management investigation. Science will give more certainty in water resources management, but will never be enough knowledge. In order to better solve or mitigate future water problems, there is an urgent need to improve strategies, approaches and solutions that will lead towards holistic, more effective and sustainable management. Water must be treated as a high political priority that is integrated into other policy areas. Universities must play a key role by helping governments how to manage and allocate water resources and provide water services. Cooperation around water, for water and through water, must happen everywhere and continuously. In the water sector, the approach is still too often based only on hydrological and climatological data, on modelling and engineering, all relying on the application on scientific and mathematical principles to practical ends such as the design, manufacture and operation of efficient and economical structures, machines, processes and systems. A synthesis of the Newtonian and Darwinian approaches to science, development of interdisciplinary science ecohydrology, will offer opportunities for progress at the intersection of physics and ecology where many critical issues in earth system science reside.

Global energy transition based on renewables and new storage technologies
Fri / 26.09. @ 17:15

The energy transition towards sustainable renewable energy is technically possible and economically feasible. There are enough renewable resources like wind and solar for the power sector. The energy storage problems are solved. Improved energy efficiency can halve the energy demand in the heating sector. What’s left is the transportation sector and the producing chemical industry, both depending over 90 % on fossil fuels like oil and gas. Besides electromobility and biofuels, power-generated fuels and chemical energy carries like naturals gas substitute (SNG), methanol, diesel or hydrogen can be generated by Power-to-Gas and Power-to-Liquid. The necessary energy resources for these “power fuels“ are huge, and one large unused potential is found at the seas in form of wind energy. A new concept of harvesting base load wind with energy ships will be presented at the conference.

The keynote will give an overview on Germany’s energy transition from today until 2050 on 90 – 100 % renewable energy supply. Several scenarios on power networks and market simulation with a high spatial and temporal resolution (14 x 14 km; 1 h) based on numerical weather models will give in-depth insight into the shape of the future energy systems and the interdependence between the different sectors for power, heat, fuels and gas. The contribution of several balancing options like network expansion, demand side integration, flexible generation and cross-sectorial energy storage will be analyzed.

A highlight of the presentation will be the presentation of a new storage and fuel generation concept, which we developed: sail energy.

The sail energy concept uses offshore wind to generate renewable fuels on board. This process is combining mechanical, electrical and chemical conversion steps: First, offshore wind is converted by various sailing technologies on a ship into mechanical translation. This force is converted into mechanical torque and electricity by using a marine turbo machine including generator fixed at the vessel, that extracts energy from the ship’s propulsion.

The generated electricity is used to split water into oxygen and hydrogen onboard in an electrolysis unit. Via the process technologies Power-to-Gas and Power-to-Liquid, hydrogen is combined with CO2 to generate gaseous and liquid fuels. These fuels are fully compatible with today’s natural gas and mineral oil infrastructure with all its multiple applications for heating systems, power plants and vehicles. By following the wind, the wind energy can be harvested constantly as base load and fuel be produced economically.

Concluding, it is possible to transform the global energy supply to a sustainable base, technically, economically and ecologically and mitigate climate change.
