Introducing the Open Energy Ontology: Enhancing Data Interpretation and Interfacing in Energy Systems Analysis

Energy security is a multidisciplinary field which overlaps with engineering and energy systems analysis, earth sciences, economics, technology studies, political science, international relations, and security and military studies. Though discussions of energy security have been around for most of the 20th century, a systematic “energy security science” has emerged only recently and is still a young and dynamic field. The structure and the borders of the area are widely debated and contested. Contemporary debates on energy security include dilemmas such as whether energy security is a “socially constructed concept” or an objective property of energy systems, whether it is primarily a national-level issue or whether it also exists at different scales (household, local, regional, and global), whether it relates only to conventional or also to “human security,” whether it is a generic or context-dependent idea, and how it relates to other energy policy issues (e.g., environmental and social impacts). The key outcomes of this debate include the idea that energy security relates to both shocks and stresses, includes both physical and economic aspects, and relates to the “vital energy systems” which underpin the stability and functioning of societies.

The Difference

With an increasing share of renewable energy technologies in our energy systems, the integration of not only direct emission (from the use phase), but also the total life cycle emissions (including emissions during resource extraction, production, etc.) becomes more important in order to draw meaningful conclusions from Energy Systems Analysis (ESA). While the benefit of integrating Life Cycle Assessment (LCA) into ESA is acknowledged, methodologically sound integration lacks resonance in practice, partly because the dimension of the implications is not yet fully understood. This study proposes an easy-to-implement procedure for the integration of LCA results in ESA based on existing theoretical approaches. The need for a methodologically sound integration, including the avoidance of double counting of emissions, is demonstrated on the use case of Passivated Emitter and Rear Cell photovoltaic technology. The difference in Global Warming Potential of 19% between direct and LCA based emissions shows the significance for the integration of the total emissions into energy systems analysis and the potential double counting of 75% of the life cycle emissions for the use case supports the need for avoidance of double counting.

Energy Systems Analysis

Dr Ilium, with degrees in Civil Engineering from the Technical University of Denmark and in Energy Systems and Energy Planning from Aalborg University, has had his own consulting company, ECOConsult, since 2000. He was from 1962 for over a decade mainly occupied with the development of educational programs in computerscience alongside with studies in systems theory and cybernetics at the Danish Academy of Engineering in Copenhagen and Aalborg.Thereafter, as senior Associate Professor (Docent) at the Department of Development and Planning, Aalborg University, he was mainly engaged in the development of methods and computer models for the technological, environmental and economic analysis of alternative scenarios for the development of energy systems and agricultural production systems. He has also been engaged in studies of environmental policies and problems in Central and Eastern European countries, in particular in energy planning in Czechoslovakia/the Czech Republic, and was Programme Manager for the Nordic Training Programme for Energy Experts in the Baltic States, the PROCEED programme. In addition, Dr Ilium has developed comprehensive computer models for: numerical analysis of thermodynamic systems (power plants, cogeneration plants, integrated industrial processes,etc.); energy planning on the national, regional and local energy system level; technological/socio-economic energy systems analysis; economic assessment of alternative energy system projects; flow analysis (nutrients and energy) and economic analysis of agricultural systems. He has developed the Sustainable Energy Systems Analysis Model (SESAM), an advanced, general computer model for the analysis of scenarios for the future development of national, regional or local energy systems which has been used and is presently being used for the integrated technological, environmental, and economic analysis of present and future energy systems infrastructures in Denmark, the Czech Republic, Poland, and Germany.
