The Danish energy company, Energinet, is interested in the SenArch solar-powered LoRaWAN gateway and is testing it to determine whether it can be used to monitor parts of Denmark's critical infrastructure. The role of Energinet is to own, operate and develop the transmission systems for electricity and gas in Denmark. With the green transition and the scaling of Power-to-X, Energinet's infrastructure will include hydrogen pipelines and energy islands at sea. Making sure these critical assets are constantly maintained requires data and this is where IoT sensors play an important part. The purpose of IoT sensors is to capture and measure parameters in the physical world and convert the parameters to digital data. In more cases than not, these sensors need to be installed in remote and out-of-reach locations where connectivity is unavailable due to poor radio signal. Energy and Utility sector infrastructure is more than often located in such locations, and this makes SenArch's off-grid IoT gateway relevant.
