The power generation industry is in transition with increasing momentum to reduce carbon emissions. Each year more renewable-based power is generated, changing the traditional electrical grid model. However, the grid still requires firming with dispatchable assets. In the future, these assets may need to have reduced or zero carbon emissions.

Transforming gas turbines into low or zero-carbon emitting systems can be done through pre- or post-combustion options. Pre-combustion choices include the use of hydrogen, renewable or synthetic methane, or biofuels. Post-combustions options include carbon capture and oxy-fuels. As hydrogen is both a fuel and an energy carrier, it is being viewed as a potential critical element for decarbonization of many sectors, including power generation.
