Hawaii is known for its lush, green jungles. Now, the islands would like to go green environmentally. Hawaiian Electric Companies put out the call to get biodiesel as part of the utilities’ 150,000 barrels of green fuel a year used to supply Maui Electric and Hawaii Electric Light Company generation facilities:

This request for proposals offers biodiesel suppliers — including local biodiesel producers — the opportunity to offer biodiesel or biodiesel blends for all or part of the required volumes on Maui, Molokai, Lanai or Hawaii Island. Proposals will be considered if the biodiesel price is competitive with the price of ULSD.

Hawaiian Electric continues to use 100 percent renewable biodiesel on Oahu in the Campbell Industrial Park Generating Station. It will also do so in the planned Honolulu International Airport Emergency Generation Facility. In addition, all diesel vehicles in the Hawaiian Electric fleets use B20, a blend of 20 percent biodiesel with 80 percent petroleum diesel.

The push to use biodiesel is part of a larger plan by the utilities to use more renewable energy, including solar, wind, geothermal, biomass, hydro, and, eventually, ocean-generated power.
