Fossil fuels are remarkably convenient and stable at room temperature. Hydrogen, on the other hand, is not. Hydrogen burns cleanly and carries more energy per kilogram than any other fuel, but it's difficult to store and move. Being the lightest element, hydrogen takes up a lot of space as a gas, so storing a useful amount means either compressing it up to 700 bar or cooling it to 20 K and storing it as a liquid. In storage or during transport, it can leak through seals that hold natural gas just fine, embrittle the metals meant to contain it, and ignite with a minimum ignition energy—a tenth of what gasoline needs, barely more than a stray static spark. In practice, it's a chain of hard engineering problems from production to end use, and stress-testing every design iteration physically is slow, expensive, and sometimes hazardous.
