Within GAINN4MED, the Port Network Authority of the Eastern Adriatic Sea – Ports of Trieste and Monfalcone) analysed the regional potential supply of suitable material for the transformation into bio-LNG by applying the model tool developed during the project duration, which was transformed into a website (https://gainn4med.porto.trieste.it/).
Also, it matched these estimations with the updated the figures of the demand for LNG in the land and sea transport sector of the port of Trieste processed as part of the COSTA II EAST – POSEIDON MED project (2013-EU-21019-S).
Thanks to the GAINN4MED project, the Port Network Authority of the Eastern Adriatic Sea – Ports of Trieste and Monfalcone gained additional knowledge on the demand, offer and supply chain of LNG and bio-LNG, leading to the submission and approval of the RTALF – Port of Trieste: Railway Terminal And LNG Facility (studies) project in the 2019 CEF call.
The Port of Trieste has joined the Gainn4Med project with the aim of improving the environmental performance of port activities and has activated an energy efficiency path thanks to other loans in progress concerning the electrification of the docks, the replacement of public areas with lights led, cold ironing designs for the RoRo dock, etc.
As part of the Gainn4MED project, the Port of Trieste has carried out the following activities:
1. Case study analysis on the port of Trieste relating to the potential demand and supply of bioGNL;
2. Update of the study on the potential market of LNG as an alternative fuel for ships already carried out in 2015 as part of the COSTA II EAST – POSEIDON MED project
3. Application of the model tool developed in the project to the Trieste case study
4. Transformation of the model tool into a web platform. How much BioGas is available in Trieste and neighboring countries?
In Trieste this value is very low, while in the Friuli Venezia Giulia Region there is a large production of BioGas: about 27,000 tons of potentially treatable Bio mass and 94,000 tons of wastewater treatment sludge were produced, for a total of 330,000 tons of forsu and 25,000 tons of special waste.
However, there is a problem: the estimate of BioGas entering the cogeneration plants is about 230,300,000 Nm3 but these are used already thanks to the incentives provided by the grid operator.
Assuming that all plants can be converted to produce biomethane and its subsequent liquefaction, the region would have a potential production of about 270 tons per day of Bio LNG.
To calculate the estimate of LNG demand for the Port of Trieste, two approaches have been adopted, the first more conservative, the other more optimistic: in both cases, the number of LNG-powered ships are not very high, so the potential LNG demand ranges from 11,000 to 43,000 tons depending on the approach.
Assuming that all the large-scale plants and at least half of the small-scale plants in the Region can be converted to the production of Bio LNG (at the end of the incentive scheme currently in use), 35% to 67% of the demand for LNG hypothesized for the Port of Trieste.
In conclusion, this study associated with the Gainn4Med Project is the starting point to define and analyze future developments of the Port of Trieste. At the same time, this vision must be agreed between terminal operators and ship owners and at the same time, an incentive policy is required by the Central Government and at the European level to avoid market misalignments.
