Connected Strategy for Hydrogen Value Chain ^ Top ^ 35 INTERNET OF THINGS (IOT) The Internet of Things (IoT) is one of the digital technologies that can support the energy transition. By connecting energy suppliers, consumers, and grid infrastructure, IoT technology facilitates the bi-directional flow of data, the operation of increasingly complex power systems and the establishment of new business models by enabling clients to further monetize the value created by their assets through demand-side management. IoT technologies are underpinning the transformation leading to cleaner, more distributed, and increasingly “smart” grids. Access to more, higher-quality data across the whole value chain enables better decision-support tools (i.e., AI) and enables remote control and automated execution of decisions (e.g., energy trading algorithm). The IoT enables real-time communication through the Internet, among devices in demand and across the grid, facilitating information gathering and exchange. The IoT, together with optimization algorithms, can:  Increase system flexibility by enabling remotely managed and/or rapid automatic changes in distributed resources and demand IoT smart meter boosts hydrogen energy sector In the U.K. and other countries, pilot schemes with hydrogen blending are underway to meet carbon-emission targets. One challenge is that no domestic hydrogen gas meters are currently available to measure and charge for gas usage. Conventional meters measure gas flow using a mechanical system based on a diaphragm. Because of the small hydrogen molecular size, hydrogen diaphragm meters would need to be about three times the conventional meter size – an impractical and costly limitation. One option is to replace mechanical diaphragm meters with ultrasonic devices. These rely on accurate 'Time of Flight' (ToF) measurement of the speed of sound to determine the gas's flow rate. But because the speed of sound in hydrogen is around three times faster than that in natural gas, significantly better timing precision is needed. In response to this challenge, U.K.-based MeterTech has launched a smart meter that uses a more advanced technique for the "recovery" of the ultrasonic signals and has timing circuits capable of measuring ToF in hydrogen. Furthermore, the meter has been designed to meet the highest safety requirements in Europe and elsewhere in the world.
