Nel ASA has secured a patent for innovative systems and methods that significantly enhance communication between hydrogen fueling stations and vehicles, thereby improving safety, speed, and efficiency in fueling processes. The patented method incorporates the use of NFC (near field communication) links and V2X communication networks to establish seamless communication between the station and the hydrogen-powered vehicle during the fueling process. The communication method outlined in the patent involves various steps such as establishing an NFC link, transmitting identifying information, selecting a V2X communication network, and delivering pressurized hydrogen to fill the tanks of the vehicle. Importantly, the system allows for fault recovery and real-time monitoring of tank data during fueling, ensuring safe and efficient delivery of hydrogen. Furthermore, the patented method enables the exchange of crucial information between the fueling station and the vehicle, including fueling protocols, payment details, and software updates. The use of communication protocols like NFC standards and V2X protocols such as IEEE 802.11, 4G LTE, or 5G mobile networks ensures that the communication system operates at an ASIL D level of safety. One of the key highlights of the communication system is its ability to update fueling protocols based on monitoring data, exchange payment information, download diagnostic details from the vehicle, and continue delivery even in case of communication interruptions. The NFC hardware used in the system is highly reliable and is rated for use in hydrogen classified areas, with a specific distance requirement for establishing the NFC link. Overall, Nel's patented communication system represents a significant advancement in hydrogen fueling technology, offering enhanced safety, speed, and efficiency in fueling processes. By facilitating seamless communication between fueling stations and vehicles, this innovative system paves the way for a more streamlined and sophisticated approach to hydrogen delivery in the transportation sector.
