The changing tides of hybrid technology.
Southern California ports continue to pioneer greener paths – this time with a hybrid tugboat. In an ongoing effort to reduce images both on land and sea, the ports of Long Beach and Los Angeles have jumpstarted an environmentally friendly - and forward thinking - partnership that could bring a hybrid tugboat to the ports in 2009.
Two of the busiest ports in the world, both Long Beach and Los Angeles see their fare share pollution and in this case, it comes in the form of, “thick, dirty sludge called bunker fuel while at sea and slurp diesel to keep the lights and air conditioning running while in port.” (insert citation) In addition, “Inefficient yard tractors and cranes guzzle fuel and spew exhaust as they stack containers. And tugboats, pound for pound the most powerful vessels on the water, waste most of that muscle idling or cruising.”
Enter the tugboat hybrid. At a cost of $1.35 million, Foss Maritime Co. of Seattle developed the tugboat hybrid that will improve water and air quality. The vessel will run on both batteries and diesel fuel.
A majority of the of the ports’ environmental focus has been on not on sea vessels – but those travelling on land. Trucks must now go through retrofitting, inspections, you name it - but all in the name of cleaner air.
On a larger scale, there are currently about 4,000 tugboats in America, according to the American Waterways Operators. GE is also in the process of creating a hybrid tug and that will work off of a diesel-electric drivetrains. The hybrid engines must be able to provide short burst of high power in order to move the gigantic freighters and tankers. GE’s technology - battery powered engines - would allow them to do both without the fuel intake the non-hybrids require now. The type of fuel intake that leads to loads of pollution. According to Wired.com, “General Electric wants to take the technology to sea in a tugboat that could burn 35 percent less fuel and emit 80 percent less pollution than anything else on the water,” (http://blog.wired.com/cars/2008/05/ge-developing-a.html) .
