SPECIAL SESSION: Hydrogen Energy Vectors for Storage and Power
The constantly increasing energy demand and enhanced enforcement of environmental regulations to reduce green house gas emission levels have been globally ecouraging the power sector to develop new strategies for diversification and security of energy supply. Although renewable energies have considerably increased their penetration in the global markets, it is well-known that these technologies suffer of fluctuating patterns. Therefore, energy storage becomes a critical parameter for future renewable energy systems. Out of the possible solutions, chemical energy storage is the only one that enables long storage periods (in years), with unrestricted geological barriers and high distribution efficiencies.
Therefore, one of the main chemicals assessed for the task has been hydrogen. The hydrogen economy has been one of the main strategies proposed for decarbonisation of the power sector since hydrogen is an environmentally clean fuel, yielding only water and energy when oxidized. Despite the environmental advantages, hydrogen has poor volumetric energy density and a low flash point, presenting technical and economic challenges associated with its storage and distribution at a large scale including hard to handle infrastructures that would be required to properly store and distribute the chemical in a safe way, excluding the expenses that will be needed to ensure its safe use.
Supporting hydrogen other chemicals have been proposed for the transition to a hydrogen economy, chemicals that contain great quantities of hydrogen and can serve as energy vectors of a wide variety of renewable and conventional energy sources. Chemicals such as ammonia, methanol, ethanol, hydrates, etc. are just a few of the available options to serve as hydrogen vectors to deliver and use hydrogen at medium to utility scale. Thus, hydrogen energy vectors are becoming the focus of various energy production systems. In combination with hydrogen, these vectors can be considered a viable solution to environmental sustainability as well as supply security.
On those lines, this session invites presentations related to the use a hydrogen energy vectors for power, cooling, heating, energy storage and human development through separation, catalysis, distribution, storage and consumption via combustion, fuel cells, propulsion/detonation or any other innovative pathway to use these chemicals. The forum will serve to gather specialist on the topic and raise awareness of novel initiatives that can support the use of these hydrogen vectors and their related technologies for a sustainable future.

SPECIAL SESSION: 10 years ahead of the SDG7: How to achieve universal electrification by 2030?
Providing universal access to sustainable, reliable, and affordable electricity by 2030 is one of the main targets of the Sustainable Development Goal #7. Latest statistics indicate that still 840 million people live without electricity and 2.9 billion people lack access to clean cooking facilities. Many of which are expected to live in the most remote regions and under the poorest socio-economic conditions. Besides more efficient and cheaper technologies, decisions support tools and appropriate framework conditions are indispensable to achieve the targets of the seventh Sustainable Development Goal.
While significant progress has been made in recent years, especially in Central and Southern Asia, it is projected that 650 million will still lack access in 2030. Therefore, this special session focuses on the diverse aspects of research for providing access to electricity. This includes policy advice and energy sector planning tools based on geospatial and macroeconomic approaches, energy system management and planning approaches for defining cost-efficient energy supply solutions, technology research as well as empirical research highlighting acceptance of energy solutions and willingness to pay.
This special session at the 15th SDEWES conference, taking place 2020 in Cologne, marks the decade left to achieve the ambitious targets of the Sustainable Development Goal #7. Therefore, this special session serves for presenting latest research findings, technological solutions, innovative planning tools, and promising approaches from both researchers and practitioners. This includes findings from different disciplines such as technical, economic, and social sciences and different project regions. Finally, the special session serves to discuss and formulate key areas of research to focus on in the next decade for advancing the SDG7 targets. The overall objective of the special session is to ignite collaboration among researchers focusing on access to electricity including transdisciplinary and interdisciplinary research.

SPECIAL SESSION: Managing the FEW-Nexus in the Anthropocene
For Paul Crutzen it was “appropriate to assign the term ‘Anthropocene’ to the present” global development. The food-energy-water nexus (FEW-Nexus) and its infrastructure represent key sectors of the Anthropocene and is therefore at the centre of the current discussion about transforming the Anthropocene into a resilient and secure sustainable development. The UN introduces resilience as a global sustainability goal and as a management concept to guide the institutional decision-making process to manage the Anthropocene.
“Resilience is usually used to describe the properties of a system” and is a central target of goal 1 (1.5), 11 (11.7), 13 (13.1) and 14 (14.2) of the UN-SDGs (United Nations Sustainable Development Goals) and a central issue of environmental decision-making at all institutional levels. The World Bank supports also this approach: “Resilience and development are inextricably linked. When we invest in infrastructure, we have to invest not just for today but for the future, and that means building resilience into everything we do.”
The resilience (from the Latin resilire = to rebound) of a system is defined as “the ability of a system to absorb disturbance and still retain its basic function and structure.”
- Humans are resilient if their psychological strength enables them to handle extreme events and stress, whereas a forest is considered resilient if it can recover from a fire storm.
A differentiation can thus generally be made between ecological and sociological resilience.
- Ecological resilienceis further broken down into
- (a) ecological resilience (i.e. resilience as a measure of the “magnitude of disturbance that can be absorbed before the system redefines its structure by changing the variables and processes that control behavior”, i.e., a system is flipped into another regime of behavior), and
- (b) engineering resilience (i.e. resilience as the ability to return to a steady state after external shocks).
- Sociological (socio-economic) resilience, in contrast, refers to the ability of societies to absorb external shocks, without changing substantial and essential system functions. The resilience of a social system can be defined as “the capacity of a system to absorb disturbance and reorganize while undergoing change so as to still retain essentially the same function, structure, identity, and feedbacks.”
In this session, the requirements of the resilience approach for the FEW nexus systems will be discussed and thereby considering both ecological resilience of the surrounding environmental infrastructure of the FEW nexus system and sociological resilience of the FEW socio-economic infrastructure to enable the institutions to manage the challenges of the Anthropocene in a sound decision-making process.
In the session the “three main criteria of a resilient system” as adopted by UNEP will be discussed and analyzed:
- “The amount of disturbance it can undergo to resist change whilst retaining on the same structure and function;
- The degree to which it is capable of self-organisation;
- The ability to build and increase capacity for learning and adaptation.”
Thereby, the interlinkage between FEW nexus sectors and the links between FEW nexus sectors and the socio-economic-ecological system (SEES) shall be considered and elaborated in the context of the Anthropocene.
