Makai’s Components Arrive at Ocean Energy Research Center in Hawaii

Makai’s Ocean Energy Research Center (OERC) in Kona, Hawaii has received several major pieces of equipment for its Ocean Thermal Energy Conversion (OTEC) demonstration plant.

Two new heat exchangers (2-megawatt thermal duty each), and a 100 kilowatt ammonia turbine-generator have arrived and are in various stages of installation and testing. To date, Makai has tested four condensers and three evaporators at the OERC, each made of either aluminum or titanium. The facility has been designed to easily swap out OTEC heat exchangers, and test as many as six simultaneously.

The Ocean Energy Research Center is an essential tool for the development and testing of candidate OTEC heat exchangers. Heat Exchangers will be the single most expensive component in a commercial offshore OTEC plant and thus optimizing their lifetime, performance, and cost are critical for OTEC’s economic success.

Beyond its own research efforts, Makai provides objective engineering services to domestic and international third-party OTEC developers, such as testing OTEC heat exchangers, corrosion samples, and providing OTEC plant and marine pipeline design and analysis support. The OERC is primarily dedicated to OTEC research, but includes research programs in other ocean-related areas, such as corrosion prevention and heat exchangers for other marine applications. With its continuous access to large flows of both shallow and deep seawater up to 3,000 feet deep, the OERC serves as a valuable platform for international collaboration on OTEC research and development.

Finally, Makai’s 100-kilowatt OTEC turbine has been placed on the OTEC tower while heat exchanger testing is being performed. Makai plans to connect the turbine to the OTEC system, and connect power to the local electrical grid in early-2015, followed by a dedication ceremony in mid-2015. This will mark the first time in history that closed-cycle OTEC power has been connected to a U.S. grid, and represents an important step toward commercializing this clean, constant (24/7) source of renewable energy.
