    Environmental data for the planning of off-shore wind parks from the EnerGEO Platform of Integrated Assessment (PIA)
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Zelle, Hein; Mika, Agnes; Calkoen, Charles; Santbergen, Peter; Blanc, Isabelle; Guermont, Catherine; Menard, Lionel; Gschwind, Benoit
    The EU-sponsored EnerGEO project aims at providing decision makers with a modelling platform to assess the environmental impacts of different sources of renewable energy. One of the pillars of the project is the Wind Energy Pilot, addressing the effects of offshore wind parks on air pollution and energy use. The methods used in the pilot and the underlying environmental databases are integrated into a WebGIS client tool and made available to the public. This paper is dedicated to describing the environmental databases and supporting data incorporated in the client tool. A 27-km resolution, 11-year wind database is created using the WRF model. The wind database is used to assess the wind climate in the north-west Atlantic region and to derive the potential power output from offshore wind parks. Auxiliary data concerning water depth, distance to shore and distance to the nearest suitable port are created to aid the planning and maintenance phases. Seasonal workability conditions are assessed using a 20-year wave database. The distance at which future wind parks should be placed to exhibit different wind climates is investigated.

    Web tool for energy policy decision-making through geo-localized LCA models: A focus on offshore wind farms in Northern Europe
    (EnviroInfo Dessau 2012, Part 2: Open Data and Industrial Ecological Management, 2012) Blanc, Isabelle; Guermont, Catherine; Gschwind, Benoît; Menard, Lionel; Calkoen, Charles; Zelle, Hein
    Environmental performances of electricity generation, expressed as environmental impacts per kWh of electricity produced, depend strongly on technical, methodological and geographical parameters. When considering the global environmental performances of renewable energies, a geo-dependent life cycle assessment (LCA) taking into account geographical issues is of high. To illustrate this issue, a web map service enabling “geolocalized life cycle assessment” of offshore wind farms for different configurations has been developed. Based on a modular LCA model and on collaborative works made within the framework of the FP7 co-funded project EnerGEO, the developed tool should help decision makers in assessing the global environmental impacts caused by an offshore wind farm in Northern Europe.
