That's true with nearly every energy source. Internal combustion energy efficiency is what? Something less than 50%. A conventional coal-fired boiler is something less than 45%. Even the latest gas turbine co-generation plants a pushing it to get much above 50%.

So, we burn some fuel, inefficiently, to create H2 and then burn the H2 to, inefficiently, move an automobile or to generate electricity? Sounds rather inefficient.

That wasn't what I suggested at all. Go back and read the post again. Energy sources are not fungible. Some are best suited for one application but totally wrong for others. A blind measure of efficiency even if technically accurate is meaningless economically.
