Vehicle data collection is crucial for advancing transportation decarbonization, as it enhances our understanding of engine performance, fuel consumption, and efficiency. By leveraging various vehicle parameters, and our interconnected network, vehicles generate vast amounts of data every second. This includes information on wheel speed, fuel consumption, acceleration, and engine load. For fleet operators, this data is invaluable, allowing them to project daily hydrogen use and necessary hydrogen off-take, while also improving insights on GHG reduction and maintenance cost savings.
