Synergy of the future: High voltage insulated power cables and railway-highway structures

The rationalisation of the territorial resources leads to consider carefully the possibilities of using motorway and railway infrastructures (existing or planned ones) for cable line installation within them. The full compatibility of such synergy \u2018transport \u2013 electrical power transmission\u2019 involves different branches of engineering. The study provides an overview of the research undertaken for a fully reliable use of this combination. The manuscript aims at highlighting a procedural approach that should be followed in order to analyse all the key elements involved in the safe operation of power transmission lines hosted in transport infrastructures. First, the geometrical compatibility between different types of power transmission technologies, (i.e. gas insulated lines and high-voltage direct/alternating current insulated cable lines), and transport infrastructures (i.e. motorway galleries, railway galleries and railway prospection tunnels) is considered. Subsequently, the behaviour and magnitude of the magnetic field generated by the different power transmission technologies inside the transport infrastructures are presented. Moreover, the study analyses the effects of a phase-to-screen short circuit that could occur inside the hosting facility. Finally, an analysis of the reliability of the synergy between power transmission systems and transport infrastructures is discussed

2009 Technology Map of the European Strategic Energy Technology Plan (SET-Plan). Part 1 - Technology Descriptions

The Technology Descriptions of the 2009 Technology Map assess the technological state of the art and anticipated developments of 17 energy technologies, the status of the corresponding industries and their potential, the barriers to large scale deployment, the needs of the industrial sector to realise the technology goals and the synergies with other sectors. The technologies addressed are: wind power, solar photovoltaics, concentrated solar power, hydropower, geothermal energy, ocean energy, cogeneration of heat and power, carbon capture and storage, advanced fossil fuel power generation, nuclear fission, nuclear fusion, electricity grids, bioenergy for power generation, biofuels for transport applications, fuel cell and hydrogen technologies, electricity storage and energy efficiency in transport. The 2009 Technology Map is the SET-Plan reference on the state of knowledge for low carbon technology in Europe, presenting a snapshot of the energy technology market situation for 2008-2009. However, the information in this work should be seen in the context of the dynamics of the energy technology market. As such, SETIS is continuously tracking and monitoring the global development and progress of energy technologies and makes this information available "on-line" in the SETIS website: http://setis.ec.europa.eu.JRC.DG.F.7-Energy systems evaluatio
