Motivation of the project
Complex territorial
morphology Urban areas are
concentrated along the coast and two
inland valleys
Complex urban
texture One of the biggest historical centre in
Europe
Mediterranean climate
Mild and short winters
High development
of NG distribution
network
What is the project about?
CONDENSED CONCEPT
• To exploit the NG pressure drop between the NG transmission and distribution network for generating electric and thermal energy to serve a micro-DHN
TECHNICAL DETAILS
• TURBO-EXPANDER [550kW] to exploit the NG pressure drop at a main gas distribution substation, generating electric energy
• GAS-FIRED COGENERATION PLANT [526 kWh] 1.To provide the heat required to compensate for the decrease of temperature occurring during NG expansion 2.To serve a Micro-DHN 3.To produce additional electricity
• REMOTE CONTROL SYSTEM
Project timeline
Design phase (Apr.2013-Apr.2015)
• Design and tender to procure the turbo expander
• Design of the CHP and related size of the micro DHN
• Civil works for preparing the area to install the turbo-expander and the micro DHN pipelines: design of underground works and foundations
• Authorizations procedures
Installation phase (May 2015- Sep.2015)
• Finalization of the civil works
• Installation of TE, CHP and pipelines
Operation phase & Monitoring (from Oct.2015)
Installation phase
Environmental benefits
Lower direct emissions to the atmosphere with respect to the current situation will be achieved. The project will make it possible to deliver both electricity and thermal energy to nearby buildings enabling savings of approx. 800 ton CO2/year. Monitoring phase over a 18 months-period.
