The United States Naval Research Lab (NRL) purchased a Model 100 Scalable Hydrogen Fueling Appliance from MRE and was installed in June 2018. They are using the hydrogen fuel it produces to fuel drones and test the range extension provided by hydrogen over batteries.
Recently NRL produced a video of the marvelous things that NRL is doing in the research to improve our military capabilities and they showcased MRE’s Hydrogen fueling station in the 1 minute video. See the link below to watch . https://www.nrl.navy.mil/news/videos
