The US Port of Oakland is seeking $56m in federal funds to boost green initiatives including increasing barge traffic along the delta and cutting ship emissions.

If granted, the port will use $30m for infrastructure improvements such as harbour cranes, rail upgrades and loading facilities at the Port of Stockton and Port of West Sacramento.

The two ports would receive more cargo via barges and barge shipping will emit fewer emissions than trucks used to transport the same amount of goods to the Sacramento area.

The port also plans to use nearly $26m for a system that combines an electrical generator powered by liquefied natural gas to reduce poisonous emissions from cargo ships at anchor.

The port is planning to use the system on five of the facility’s 26 berths.

According to the port its green proposals will appeal to the federal transportation officials who will decide the fund award by February 2010.
