Special Issue Information

Dear Colleagues,

As fossil fuel thermal power generation is progressively phased out, gas turbines emerge as the best thermal power generation technology capable of converting hydrogen to electricity at scale and with high efficiency and low emissions. Furthermore, the versatility of the technology allows its combination with renewable energy such as in the case of solar and biomass fired gas turbines and its hybridization with fuel cells to achieve even higher conversion efficiencies. Additionally, a novel research and development community has emerged in the last decade that works on the adaptation of gas turbines with pressure gain combustion. A successful application of this technology will increase conversion efficiency and also enable the decarbonization of the sector. All of these efforts are active topics of research currently vital to facilitate their adoption, efforts which have been globally recognized through a strong push to address industrial emissions, announcements for ambitious hydrogen energy strategies, and for the digitalization of energy systems.

In this context, the current Special Edition aims to provide an overview of the activities of the research and development community in the fields of novel approaches in gas turbines. The focus lies on activities directed toward the adaptation of the technology for its application in a decarbonized society. Research articles mainly on (but not strictly limited to) the following topics are welcome:

  • Hydrogen in gas turbine applications;
  • Concentrated solar power gas turbines;
  • Pressure gain combustion in gas turbine applications;
  • Fuel cell–gas turbine hybrids;
  • Biomass fired gas turbines;
  • Alternative applications of the Joule–Brayton cycle.

High pressure humidified cycles can combine high operational flexibility and high thermal efficiency. The current work introduces such a cycle, namely TopCycle, which provides the necessary combustion infrastructure to operate on a wide fuel variety in a steam-rich atmosphere. The cycle configuration is presented in detail, and its operation is exemplified on the basis of simulation results. Operation at design condition results in electric efficiencies higher than 50% (lower heating value (LHV)) and power densities higher than 2100 kW/kgair (referred to intake air flow). A sensitivity analysis identifies the cycle performance as a function of representative parameters, which provide the basis for future operation and design improvements. As for any gas turbine cycle, TopCycle’s electric efficiency can be effectively improved by increasing the turbine inlet temperature, optimizing the economizer heat recovery, as well as elevating the working pressure. Finally, TopCycle’s performance is compared to a state-of-the-art combined cycle (CC) at equivalent operation parameters. The TopCycle operates at an elevated electric efficiency and considerably higher power density, which can be transferred into smaller plant footprint and dimensions and thus lower investment costs at equal power output in comparison to a CC.
