Altair Nanotechnologies Inc. has been awarded a firm contract with the Hawai'i Natural Energy Institute (HNEI) of the University of Hawai'i at Manoa to supply a 2-MW ALTI-ESS Advantage energy storage system for a grid stability demonstration project.

HNEI selected Altairnano and the ALTI-ESS Advantage after two prior energy storage system purchases focused on renewable energy integration. The ALTI-ESS Advantage supplies 2 MW of power and 397 kWh of energy as part of a new product offering that has a 25 percent smaller footprint and lower cost per MW than the product it replaced. The research project, funded through a grant from the Office of Naval Research, will help validate the performance characteristics of the ALTI-ESS Advantage and demonstrate the effectiveness of energy storage to integrate solar photovoltaic power generation into the electric grid.

"With this project, we will continue important work to validate the effectiveness of advanced energy storage systems in improving the electric grid, reducing emissions and providing the citizens of Hawai'i with continued growth in the use of renewable energy," said Rick Rocheleau, executive director of HNEI.

"Energy storage systems will play a critical role in the integration of renewable sources of energy into the grid," said Alexander Lee, chief executive officer of Altairnano. "We are very pleased to build upon our relationship with HNEI, and look forward to integrating our newest system, the ALTI-ESS Advantage, into our third renewable energy project with HNEI."

The Office of Naval Research is providing funding for the project through a grant to the University of Hawai'i. Projects that support the Department of Navy's energy programs to demonstrate technologies that enable increased implementation of alternative energy sources and promote energy security was made possible by the efforts of the late Senator Daniel K. Inouye, Senate Appropriations Chairman, to ensure that the Department of Defense has adequate resources to make these critical, cutting-edge investments in energy technology.
