HIDOE Thermal Comfort Portal January 25, 2018

HNEI Partners with HIDOE to Create Thermal Comfort Portal

The DOE Thermal Comfort Portal is a research tool developed for State of Hawaii Department of Education (HIDOE) to implement their heat abatement program: (http://hnei.hidoe-thermal-comfort.4dapt.com). The Thermal Comfort Portal as a research resource for microclimatic data across Hawaii as well as specific building performance of the public schools.  In addition to providing data for current users, the intent is to broaden the program participants to include the sustainable design community, who can contribute to solutions but who are currently outside of the specific scope of HIDOE heat abatement program.  Under this project, the Hawaii Natural Energy Institute (HNEI) is provide the HIDOE with the technical resources and expertise to support the delivery of energy and weather data that enables researchers, the community and design professionals to make data-driven decisions for designs and resource allocation.

This work and the portal allows HIDOE to 1) provide access to local weather data to help schools with short-term decisions related to weather, 2) provide community members access to data on local micro-climates at school campuses allowing for further study, 3) identify areas that have consistent heat issues for targeted thermal comfort improvements by providing relevant outdoor and indoor temperature readings, and 4) provide detailed information from classrooms that help architects and planners design heat abatement solutions to address the specific issues for particular buildings.

Springer Handbook February 3, 2017

HNEI’s HiSERF Featured in Springer Handbook of Electrochemical Energy

The recently published Springer Handbook of Electrochemical Energy featured a chapter entitled “Modern Fuel Cell Testing Laboratory” based on HNEI’s Hawaii Sustainable Energy Research Facility.  The chapter describes the laboratory’s background and evolution, safety and test stations, fuel cell components  and assembly, and testing and diagnostic techniques.  Contributors included Jean St. Pierre, Michael Angelo, Keith Bethune, Jack Huizingh, Tatyana Reshetenko, Mebs Virji, and Yunfeng Zhai.

Google Books states that "this comprehensive handbook covers all fundamentals of electrochemistry for contemporary applications. It provides a rich presentation of related topics of electrochemistry with a clear focus on energy technologies. It covers all aspects of electrochemistry starting with theoretical concepts and basic laws of thermodynamics, non-equilibrium thermodynamics and multiscale modeling. It further gathers the basic experimental methods such as potentiometry, reference electrodes, ion-sensitive electrodes, voltammetry and amperometry. The contents cover subjects related to mass transport, the electric double layer, ohmic losses and experimentation affecting electrochemical reactions. These aspects of electrochemistry are especially examined in view of specific energy technologies including batteries, polymer electrolyte and biological fuel cells, electrochemical capacitors, electrochemical hydrogen production and photoelectrochemistry."

Net Zero Buildings Open at UH Manoa

Two net zero buildings installed for the College of Education by the Hawaii Natural Energy Institute and funded by the Office of Naval Research, opened their doors to the public in celebration of the FROG 1 and 2 grand opening on November 4. These FROG (Flexible Response to Ongoing Growth) classrooms will serve as models of energy efficient classroom design, minimizing energy use in a mixed-mode environment while using self-generated, renewable energy to offset energy consumption. Real-time building performance is displayed to users via a touch-screen dashboard, and the data is downloadable and can be integrated into STEM curricula.

Hawaii Clean Energy Final PEIS Report June 7, 2016

Hawaii Clean Energy Final PEIS Report

In July 2012, in coordination with the USDOE and DBEDT, HNEI contracted New West Technologies to conduct a Programmatic Environmental Impact Study (PEIS) to analyze, at a programmatic level, the potential environmental impacts of clean energy activities and technologies in the following clean energy categories: (1) Energy Efficiency, (2) Distributed Renewables, (3) Utility-Scale Renewables, (4) Alternative Transportation Fuels and Modes, and (5) Electrical Transmission and Distribution (including undersea cables).

The PEIS provides federal and local agencies, policymakers, energy developers, and the public with information and guidance on adhering to all laws and permitting requirements, implementing well-planned best management practices and mitigation measures, and consideration of community and cultural concerns that can be used to make decisions about renewable energy and energy efficiency deployment.

10th International Workshop on Methane Hydrate Research and Development

Hawaii Imin International Conference Center, Honolulu, Hawaii, USA.

June 15-17, 2016

The 1st International Workshop on Methane Hydrate R&D was held in March 2001 in Honolulu, Hawaii. The primary objective of that and subsequent workshops was to provide a forum where hydrate researchers and stakeholders could freely exchange information and identify research priorities in an effort to promote collaboration. Subsequent workshops have been held, on average, every 1.5 years in different countries including the U.S., Chile, Canada, U.K., Norway, New Zealand, Japan, and India.

Creating renewable gasoline

Creating gasoline and biodiesel from readily available microbial organisms may sound too good to be true, but that is exactly what researchers at the Hawaiʻi Natural Energy Institute at the University of Hawaiʻi at Mānoa are doing. A new one-pot process is described in a recent publication by Hawaiʻi Natural Energy Institute Postdoctural Fellow Shimin Kang and Researcher Jian Yu.

“As we refine this process, we will be able to simplify and bring down the cost of converting renewable feedstock to commercially viable transportation fuel,” said researcher Kang.

Biomass to biofuel

There are several different types of feedstock—defined as any renewable, biological material (biomass)—that can be used directly as a fuel or converted to another form of fuel or energy product. Common examples of biomass feedstocks include corn starch, sugarcane juice and purpose-grown grass crops that can be used to derive fuels like ethanol, butanol, biodiesel and other hydrocarbon fuels.

For a fuel to be considered good enough to use in modern high performance automobiles, it needs to have a high antiknock quality (octane number) and low oxygen. Since biomass generally has high oxygen content, it can be a challenge to create a high quality fuel without using multiple complex steps under high pressures and temperatures that can result in high costs of equipment and operation. Researchers are addressing this challenge by testing alternative feedstocks and new processing technology.

Bacterial biomass and a solid catalyst

Like starch and oil accumulated in plants, polyhydroxybutyrate (PHB) is an energy storage material accumulated from renewable feedstock in many microbial species. Following up on studies showing that PHB could be reformed into oil in liquid phosphoric acid solutions, Kang and Yu tested the process using a solid phosphoric acid as a catalyst. They were able to produce high quality bio-oils, a light gasoline-grade biofuel and a heavy biodiesel-grade biofuel, in a simple one-pot reaction.

“By using a solid catalyst we were able to increase the aromatics content, thereby raising the octane number, while reducing the water content in the resulting commercial grade oils,” said Kang.

With this new, more efficient, method researchers were able to achieve results with reaction temperatures low in comparison to catalytic conversion of conventional biomass. This may help bring down the cost of conversion to biofuel. With future work building on these results, they hope to develop a standard method to create a consistent fuel.
