   Gas turbine  evaluated  
Gas turbines have been in use in railways for decades, especially outside Europe. In recent times, with pollution standards becoming tougher and modern micro gas turbines arriving on the market, gas turbines have returned to discussion as an alternative to diesel traction.
Technology field: Innovative traction concepts and energy sources

  close sub-section Status of development outside railway sector: in use
   
  • Micro gas turbines for decentralised power generation are available on the market.
  • Automotive applications such as the Volvo Environmental Concept Truck (cf. Description) are at a pilot stage.
  Time horizon for broad application outside railway sector: in 5 - 10 years
   
  • In decentralised power generation, gas turbines are expected to diffuse into the market in this decade (cf. market potential).
  • In automotive sector, the wide-spread use of gas turbines is doubtful and would take over ten years.
  Expected technological development outside railway sector: dynamic
    The developments in the field of micro gas turbines in recent years show that gas turbines still offer considerable innovation dynamics. This concerns among other things efficiency and fuel economy.
  Market potential outside railway sector: high
    Especially in the field of industrial gas turbines for power generation market potential is seen as very promising. According to a study by the consultancy Frost&Sullivan the European market for micro gas turbines is considerable since many energy suppliers will use the technology for decentralised power generation. Frost&Sullivan predict that the number of sold microturbine decentralised power plants will grow from presently a few dozens to more than 5000 by 2010. This concerns especially gas turbines in the power class between 100 and 500 kW. This assumption could however conflict with existing over-capacities in European electricity markets.
