Better Place

Hawaii Electric Vehicle Network Initiative

PROBLEM Electric vehicles present a large new load for the utility but also a potential energy management asset.

HREDV PROJECT Better Place installed infrastructure for 9 electric vehicle charging stations at the Sheraton Waikiki and Hawaii Electric Company facilities and is using 7 electric vehicles to demonstrate the first integrated vehicle-to-grid technology on Oahu.

Big Island Biodiesel

High Vacuum Biodiesel Distillation Unit

PROBLEM  Current biodiesel technology can use only limited feedstocks; new plant-based feedstocks are needed to produce fuel on a larger scale.

HREDV PROJECT  Big Island Biodiesel, a subsidiary of Pacific Biodiesel, will build an HVD unit in a 5 million gallon per year facility that can process a wide range of agricultural feedstocks into high quality biodiesel.

Concentris Systems

Meshed Intelligent System for Energy-use Reduction (eMISER)

PROBLEM  Energy use is highly variable in non-metered homes, and is not monitored or managed remotely.

Gen-X Energy Development

Off-grid Commercial Scale Wind Storage Platform

PROBLEM Farm irrigation and pumping systems in Hawaii run on fossil fuels with high and increasing costs.

HNU Energy

Megawatt-Class Storage for Renewable Source Grid Integration

PROBLEM  As Hawaii adds more solar power, new turn-key solutions are needed to ensure grid reliability and efficiency.

HREDV PROJECT  HNU Energy will install a 1 MW, 1 MWh lithium-ion battery on Maui to smooth the short term variability of solar and to supply energy in the evening during peak demand, enabling more renewable energy to come online.

Kuehnle AgroSystems

Algae Biomass for Biofuel Production

PROBLEM Biofuels that are drop-in replacements for oil often need large tracts of agricultural land.

HREDV PROJECT Algae Biomass for Biofuel Production Kuehnle AgroSystems is building a system to continuously produce algae for biofuels; the system will pipe CO2 and wastewater from an industrial facility into the algae tanks to accelerate algae growth and demonstrate CO2 emission reductions.

Referentia Systems

Grid Renewables Integration Decision Support Systems (GRIDS2)

PROBLEM  The utility collects a mountain of data that is not immediately useful or accessible to operators.

Satcon

Grid-interactive DC-link PV Charging Station 

PROBLEM  Photovoltaics supply variable energy and electric vehicles add unpredictable load; both can impact grid stability.

Sopogy

Micro Concentrated Solar Power Absorption Air Conditioning

PROBLEM  High electricity cost for air conditioning; photovoltaics are limited on many sunny circuits because of concerns about grid stability.

The Gas Company

Biofuel Demonstration Plant

PROBLEM  Oahu does not currently have a refinery capable of processing bio-oils into gas and liquid products.

HREDV PROJECT  The Gas Company will build a pilot plant to process 1 million gallons per year of oil from agricultural and algae feedstocks into products such as synthetic natural gas, gasoline, diesel, and hydrogen.
