In September 2021, Natel conducted formal testing with PNNL on a cohort of American eel passing through the RHT test unit operating at 670 rpm under 10 m of hydraulic head. Following the test the eels were monitored for 48 hours with 100% survival.
French renewable energy news site Révolution Énergétique celebrates Natel's FishSafe™ designs as a way to "[avoid] transforming fish into rillettes."
The Cleanie Awards® announced that Natel won bronze in the 2022 Clean Energy Startup Company of the Year category. The RHT was also recognized as a Pioneer in New Technology finalist.
