129050 - Operation Planning for Hydrogen Co-Combustion in Combined-Cycle Power Plants 

Hydrogen Co-Combustion is seen as an important measure to reduce carbon dioxide emissions of gas combined-cycle power plants. Besides technical challenges, the addition of a new fuel introduces a need for more advanced economic planning, taking into account new and existing technical constraints. The paper will demonstrate a gradient-based dynamic optimization routine that is applied to a natural gas-fired combined cycle power plant model with hydrogen co-combustion and real-world boundary conditions. Boundary conditions include variable electricity prices, fuel cost as well as ambient conditions. Three different variants of hydrogen supply will be modelled, optimized, and discussed:

Discontinuous Hydrogen supply from tube trailers and ships with fixed price.

Continuous Hydrogen pipeline supply with fixed price.

Onsite Hydrogen production and storage with electricity price-dependent production cost.  

To identify optimal operation trajectories, the optimization objectives are minimizing operational expenditures such as fuel and emission costs while considering technical constraints such as hydrogen supply availability, onsite hydrogen storage capacity and state of charge, production capacity, plant gradient limitations, and ambient temperature-dependent gas turbine power. As an output, preferable supply variants for hydrogen co-combustion will be suggested. In addition, natural gas and carbon dioxide saving potential will be quantified and discussed depending on local site conditions.
