Six energy technologies that do everything from protect fish to monitor the health of flow batteries are getting a boost at the Department of Energy's Pacific Northwest National Laboratory.DOE is awarding PNNL nearly $1.5 million to bring six technologies closer to commercial use. The projects were announced today by DOE's Office of Technology Transitions, which selected them for funding from its Technology Commercialization Fund. The technologies show great promise, but need further development to improve their potential use in commercial products or services.
