The problem with all turbines is that they are only efficient at maximum power.

One of the ocean shipping companies (either Sea-Land or APL, I don't recall which) built a bunch of turbine powered container ships, designed to run at 33 knots (~40 mph). They worked great, but then the price of oil went way up. To save fuel, they tried to run them at 16 knots. I don't recall what the fuel consumption numbers did, but it wasn't enough. The company had to get rid of the ships, and replace them with diesels. Today, all commercial ships are powered by diesels.

Except for LNG tankers that feed of their cargo to fuel the burners, but that is about to change too
