From field to ferry - Liquid biogas the sustainable marine fuel of the future?
The Island of Samsø has worked with renewable energy since 1997.
Status today; the Island is 100% supplied by renewable energy - making it CO2 neutral.
The Islands latest goal is to replace all fossil fuels with renewable energy.
A new LNG powered ferry from 2015 is 600 pax, 160 cars with 4 dual fuel generator sets. The crossing takes 1 hour to and from the island.
The ferry has its own -shore to ship bunker facility - which is capable of bunkering the vessel in 10 minutes for a day of operation - the racing car equivalent of a formula 1 pit stop.
Right now the LNG is supplied by truck delivery every 3 to 5 days depending on consumption.
The island has enough biomass resources to fuel the ferry. It is technically possible to establish the entire value chain; from the farmers to - the biogas digester to - the gas purification to - liquefaction to - the ferry.
Competing against world marked prices the prospect of LBG seems far off, in a future where the negative impact of CO2 is reflected in the end user price tag – but considder these benefits:
A local “biomass refinery” on Samsø will create 13 new permanent jobs on the island.
“Field to ferry” value chain provides new opportunities to a hard pressed agricultural sector – new ways to make income.
The “biomass refinery” can substitute 50% of imported fertilizer with locally made with the same or better plant nutrients.
