Definitions

  • the present disclosure deals with an installation for delivering electricity and heat.
  • the disclosure also deals with a corresponding process for delivering electricity and heat.
  • One known type of installation includes a CCGT (Combined Cycle Gas Turbine), able to produce said electricity and heat.
  • CCGT Combined Cycle Gas Turbine
  • Such an installation performs well in terms of electricity and heat production, particularly for internal or local users, but also for external users, such as district heating and local, regional or national electricity grids.
  • renewable energy units such as a photovoltaic and/or solar thermal units in an industrial installation
  • integration of renewable energy units such as a photovoltaic and/or solar thermal units in an industrial installation
  • Using a photovoltaic unit may allow a significant reduction of the gas turbine average load, or even a reduction of the number of gas turbines installed.
  • the CCGT needs to operate in a continuous mode, above a minimum load rate mainly imposed by the gas turbine. Even when a lot of renewable energy is available, the CCGT will still consume a certain amount a fuel, so that, on average, the level of decarbonization of the delivered electricity and heat remains modest.
  • a 100% decarbonization level is an ideal situation where no hydrocarbon fuel at all is consumed. On the contrary, a 0% decarbonization level correspond to a fully fuel based installation. In practice, the decarbonization level achieved by the existing installations with renewable energy units remains below 40%.
  • An aim of the invention is to solve or improve the above issues, in particular to provide an installation for delivering electricity and heat that increases the level of decarbonization.
  • the invention proposes an installation for delivering electricity and heat, comprising:

  • the installation 10 is for example also adapted to receive electricity from said local, regional or national grid 20.
  • the split between the production facility 16 and the users 18 in the installation 10 is somewhat "artificial" here, as some of the users 18 could be considered as part of the production facility 16 itself. In other words, at least some of the local users 18 are internal users of the production facility.
  • the users 18 advantageously comprise one or several electricity user(s) 24 and one or several heat user(s) 26.
  • One electricity user may also be a heat user.
