E-Mail Future novel hybrid energy systems could lead to paradigm shifts in clean energy production, according to a paper published last week in Joule. Researchers from the U.S. Department of Energy's (DOE's) three applied energy laboratories--Idaho National Laboratory (INL), the National Renewable Energy Laboratory (NREL), and the National Energy Technology Laboratory (NETL)--co?authored the paper describing such integrated energy systems. Their effort outlines novel concepts to simultaneously leverage diverse energy generators--including renewable, nuclear, and fossil with carbon capture--to provide power, heat, mobility, and other energy services. The historic collaboration between the nation's nuclear energy, renewable energy, and fossil energy laboratories aims to address a grand national challenge from an objective, holistic perspective.
