As the turbine turns...

Abstract

The five GGTN articles highlighted here present state-ofthe- art information on the evolving role of gas turbines to decarbonize energy conversion systems. It is apparent that efforts in Europe and Japan to use hydrogen as a renewable, CO2-free fuel for gas turbines are well advanced. (History shows that hydrogen was first used as the fuel for Hans von Ohain's very first jet engine in Germany in 1937 [6].) Gas turbines should play a key role in decarbonization through their use in grid storage technologies. One expert in this area has recently written me that new gas turbine heat storage concepts are multiplying like rabbits, and we should see all sorts of combinations being proposed in the next five years. Stay tuned!.
