Power to hydrogen to power: thermodynamic and economic assessment of an Electrolyser - Hydrogen turbine system

In the realm of sustainable energy solutions, the synergy of wind energy, hydrogen, and converted gas turbines could be an important combination to ensure a smooth transition towards a less polluting electricity grid. Wind turbines serve as a primary driver, converting the kinetic energy of the wind into renewable electricity, while the utilization of green hydrogen, produced from electrolysis powered by renewable energy, provides a versatile energy vector that can replace the fossil fuels. A noteworthy way to employ this vector to close the cycle from power to power, is the reconfiguration of gas turbines for hydrogen combustion. This entails the retrofitting of existing gas turbine infrastructure, adapting it for hydrogen fuel, thereby enabling a cleaner and more sustainable mode of energy production. This innovative approach aligns with the imperative of repurposing legacy systems in the pursuit of reduced carbon emissions. The integration of wind energy, hydrogen, and converted gas turbines will be analysed focusing on the thermodynamical and economical aspects in order to assess its feasibility in the near future. However, the seamless implementation of this technical triad will be greatly affected by evolving technological standards, substantial infrastructure investments, and the formulation of adaptive policy frameworks.
