The U.S. and South Korea have maintained a strong political alliance since the establishment of the ROK after World War II. There have been many manifestations of this alliance, including close cooperation in energy--R&D collaboration, industry integration, etc. The US-Korea energy partnership continues today in many ways, including advanced nuclear development, hydrogen and fuel cell research and commercialization, etc. These tangible examples of US-Korea energy cooperation represent only a small fraction of possible opportunities.
