Luis Vega

Luis Vega | Renewable Energy Consultant

Topic: Strategy for the Next Stage of Worldwide OTEC Development

Luis Vega holds degrees in Applied Mathematics, Aerospace Engineering and Applied Ocean Sciences from the US Naval Academy, CALTECH and the University of California. His professional experience ranges from analytical studies to laboratory scale and model basin tests as well as at-sea tests of marine renewable energy equipment. He lead the team that designed and tested two Ocean Thermal Energy Conversion (OTEC) experimental plants (210 kW OC-OTEC and 50 kW CC-OTEC) demonstrating 24/7 production of electricity and desalinated-water and obtaining operational data required for estimating realistic costs of production. He has also worked in electrification of remote villages in South Pacific Island Nations utilizing solar and wind resources and establishing a Rural Energy Service Company in the nation of Fiji.

Previously, he managed the Hawaii National Marine Renewable Energy Center (HINMREC) at the Hawaii Natural Energy Institute (HNEI) of the University of Hawaii. HINMREC supports the US Navy at the Wave Energy Test Site located at Marine Corps Base Hawaii (MCBH) in facilitating the development and implementation of commercial wave energy systems. Another objective of HINMREC is to assist the private sector move ocean thermal energy conversion (OTEC) systems beyond proof-of-concept to pre-commercialization (
