What do you exactly mean? What sort of data do you need? If you mean in hydrogen producing firms, you can google them. There's a lot in Asia and US, but you have to contact them like you're doing an interview to get data.They usually don't publish data. But mind you, hydrogen production is an old industry so there's no need for experimental data because there is already an established fact (or set of facts) like you know a scientist needs to study a hyphothesis and then from related lit and all those researchers, he would formulate an objective and method, then implement it and come up with a conclusion. It's like asking to
prove the law of gravity in year 2000. But maybe I just didnt get you're point and you may want to elaborate on your inquiry.
