The US Department of Energy (DOE) is awarding $35 million to 11 projects as part of the Advanced Research Projects Agency-Energy’s (ARPA-E) Submarine Hydrokinetic And Riverine Kilo-megawatt Systems (SHARKS) program. SHARKS teams will develop new economically competitive Hydrokinetic Turbines (HKT) designs for tidal and riverine currents. Hydrokinetic energy is an abundant renewable resource that can boost grid resiliency and reduce infrastructure vulnerability, but it is currently a cost prohibitive option compared to other energy generating sources. SHARKS teams will address this barrier by designing new, efficient HKT systems that utilize America’s tidal, riverine, and ocean resources to develop economically attractive energy generation opportunities. SHARKS projects address at least one of four generation use-cases: remote riverine energy, remote tidal energy, utility scale riverine energy, and utility scale tidal energy. Projects are encouraged to apply concurrent (as opposed to sequential) design methodologies: control co-design, co-design, and designing for operation and maintenance. […]
