Work in bioplastics leads to $1.4 million contract

Thanks to the efforts of a Hawaiʻi Natural Energy Institute researcher, the University of Hawaiʻi at Mānoa has signed an exclusive global research contract with Bio-On, an Italian intellectual property company, representing a $1.4 million investment.   

Dr. Jian Yu’s research focuses on new technologies to produce bioplastics from inexpensive feedstocks such as wood chips, agricultural residues and domestic wastes. The bioplastics can be molded and shaped like oil-based plastics, but are completely degraded into benign products (carbon dioxide and water) in the environment.  The research will also make the bioplastics more ductile for broader applications such as films and fibers.

For that purpose, Bio-On has invested $1.6 million over the past seven years into the research, and will invest the additional $1.4 million to continue Dr. Yu’s research.  UH has given the company exclusive global license of two patents for production of bioplastics from domestic waste. 

“I am glad to have this new research support from Bio-On, which is based on successful cooperation in multiple projects over the past seven years,” said Dr. Yu.  “The new project shall promote our research on environmentally friendly bioplastics for a sustainable society.”

First net zero energy buildings under construction at UH Mānoa

On June 15, 2015 contractors broke ground for the installation of two 1,500 square foot, net zero energy classrooms. These classrooms will be energy neutral, that is they will generate at least as much energy as they will use.

“This multiyear effort characterizes the effect of usage and building design on energy demand. This is part of a larger research program intended to evaluate the performance and integration of a range of energy technologies that includes energy efficiency, storage and renewable generation systems,” said Richard Rocheleau, Hawaiʻi Natural Energy Institute (HNEI) director.

The University of Hawaiʻi at Mānoa College of Education will use these classrooms that were funded by HNEI, through a grant from the Office of Naval Research, and designed and installed by Project Frog, a California architecture company. Site work, hardscape, and landscaping are funded by the UH Mānoa Office of Planning and Facilities.

New study models path for achieving Hawaiʻi’s renewable energy targets

The Hawai‘i Natural Energy Institute (HNEI) at UH Mānoa, in partnership with GE Energy Consulting, has completed an analysis identifying various scenarios that would allow the islands of O‘ahu and Maui to surpass Hawai‘i’s 2020 renewable energy targets while lowering electricity costs.

The study evaluated various mixes of renewable energy generation (primarily wind and solar), different island-interconnection strategies, and changes to utility operations to identify cost-effective pathways to meet the state’s Renewable Portfolio Standards (RPS) targets. Funding for the Hawai‘i RPS Study was provided by the U.S. Department of Energy and the State of Hawai‘i via the Energy Systems Development Special Fund (aka, “barrel tax”).

Azura wave energy device off of Kaneohe Bay, Hawaii.

Wave energy device activated off Kāne‘ohe Bay

Northwest Energy Innovations (NWEI) has deployed its “Azura” wave energy conversion (WEC) device in waters off Marine Corps Base Hawai‘i at the U.S. Navy’s Wave Energy Test Site (WETS) on the island of O‘ahu. The device will be deployed for 12 months of grid-connected testing as part of a rigorous program to validate the technology.

The Hawai‘i Natural Energy Institute (HNEI) is working in conjunction with the Department of Energy (DOE) and the U.S. Navy to provide an independant verification of device performance and to evaluate the environmental feasibility of wave energy generation. The data will be delivered to the DOE and the U.S. Navy for their use in ongoing efforts to validate wave energy technology and advance the marine renewable energy industry.

Fast-Fill hydrogen fueling station enabling zero emission transportation

The Hawai‘i Natural Energy Institute (HNEI) has commissioned a “Fast-Fill” high-pressure hydrogen fueling station at the Marine Corps Base Hawai‘i (MCBH), Kaneohe Bay. This state-of-the-art station was developed to support a fleet of General Motors Equinox Fuel Cell Electric Vehicles (FCEV) leased by the Office of Naval Research for use by Marine Corps and Navy personnel on O‘ahu. Operational since November 2014, this station was recently certified for unattended operation, allowing drivers to self-fill their cars just as they would do at any gasoline fueling station. Unattended operation will serve as a model for the installation of private stations throughout the state.

Navy expands investment at wave energy test site

Work at the Wave Energy Test Site (WETS) located off Marine Corps Base Hawaii at Kāneʻohe has received an infusion of $9 million from the U.S. Navy. The funds, from the Naval Facilities Engineering Command (NAVFAC), are directed to the Applied Research Laboratory at the University of Hawai‘i (ARL/UH), working with UH Mānoa’s Hawaii Natural Energy Institute (HNEI), to support industry testing of wave energy conversion devices. The Kāneʻohe site will be the first wave energy test site in the United States connected to an active power grid. (July 21, 2014)

Hydrogen-powered Buses Coming to Big Island

Hawaii Island could be less than a year away from having some of the first hydrogen-powered buses in the state on its roadways. As part of a pilot project spearheaded by the Hawaii Natural Energy Institute, three shuttle buses will be converted to hydrogen power. Two will be provided to Hawaii Volcanoes National Park, while the third goes to the Hawaii County Mass Transit Agency, also known as Hele-On.  (June 24, 2014.)
