A Sandia National Laboratories project team, including a number of industry partners, is designing and building a cold-ironing fuel cell system that will be deployed in the Port of Honolulu in 2015. Ports have been a major source of water and air pollution in the US, but remained relatively unregulated until recent years.
A recently released total fuel cycle analysis for maritime case studies shows that natural gas fuels reduce some air quality pollutants substantially, and reduce major greenhouse gas (GHG) emissions slightly, when compared to conventional petroleum-based marine fuels (low-sulfur and high-sulfur). This is an important consideration.
The Maritime Administration is committed to finding new and efficient technologies for use in the maritime industry that reduce pollution and protect our environment. Rather than a tour boat that would primarily be a demonstration project, Red and White Fleet believes a high-speed passenger ferry makes economic sense.
The island gets on average nearly 3,000 hours of sunshine per year, putting it on a par with Honolulu and Brisbane, Australia. During prolonged outages, they can provide a cleaner and less expensive alternative to emergency diesel generators. Several factors combine to make Puerto Rico an ideal place for solar power and microgrids.
Project partner Young Brothers operated the generator for 10 months powering refrigerated containers in Honolulu, Hawaii. One opportunity to do so was identified in Honolulu Harbor at the Young Brothers Ltd. (YB) By comparison, the net efficiency of a comparable diesel generator efficiency is from 25% to 34% in this same load range.
Auxiliary power to docked ships, usually provided by on-board diesel engines, is a significant source of greenhouse gas emissions and air pollution, accounting for one-third to one-half of the in-port emissions attributed to ocean-going vessels. Honolulu, Hawaii; and Seattle, Wash. —Pratt and Harris (2013). Oakland, Calif.;
