That's an inherent limitation of heat engines - if you burn the same thing in a power plant, then you could get 45% instead of 35%, but you can't possibly convert, say, 80% of burned fossil fuel into productive work.

Not 80%, but combined cycle gas turbines regularly achieve up to 60% steady state efficiency. There is research into ammonia fueled turbines that supposedly achieve even higher efficiency.
