Interactive OTEC Power Atlas

HNEI researchers combined ocean thermal data available through the NODC's World Ocean Atlas with the HNEI OTEC thermodynamic model to provide the user an estimate o

Wave Energy Test Site (WETS)

The Hawai‘i Wave Energy Test Site (WETS), the United States’ first grid-connected test site of this kind, will be completed by the US Navy in mid-2015. The Hawai‘i Natural Energy Institute (HNEI) is providing key research support to this national effort in the form of environmental monitoring, independent wave energy conversion (WEC) device power performance and durability analysis, and critical marine logistical support.

Project Profile


Hawaii National Marine Renewable Energy Center

Hawaii National Marine Renewable Energy Center

The primary objective of HNEI’s Hawaii National Marine Renewable Energy Center (HINMREC) is to facilitate the development and implementation of commercial wave energy systems.  Funded by the US Department of Energy (US DOE), Wind and Water Power Technologies, this effort compliments HNEI’s support of the Navy’s Wave Energy Test Site (WETS) test facility at Marine Corps Base Hawaii (MCBH) in Kaneohe Bay.  WETS provides a demonstration site for emerging wave energy conversion (WEC) devices to be tested and evaluated under grid-connected, open water conditions.  The ultimate objective of this effort is to support development and commercialization of marine and hydrokinetic (MHK) technology by providing a testing infrastructure that allows developers to prove their devices and generate the necessary data to advance their designs toward commercial readiness.

A second objective of HINMREC is to assist the private sector to move ocean thermal energy conversion (OTEC) systems beyond proof-of-concept to pre-commercialization.  HNEI’s technical role with the Center is primarily focused on system and component engineering, along with local and global environmental studies.  HINMREC continues to maintain high-resolution models of the ocean thermal resource data and sustainable power output with OTEC systems.  Additionally aluminum alloys are being tested for use in MHK devices operating in the corrosive marine environment.
