The major technological challenges in the fight against global warming are to design sustainable, safe, efficient and economical power generation and seasonal energy storage solutions. Although many technologies have been tested, some of them proven, power generation with small vertical axis wind turbines and energy storage in Liquid Organic Hydrogen Carrier (LOHC) have been overshadowed, one by the development of large horizontal wind turbines and the other by high pressure hydrogen storage.
The EOLOHC project aims to numerically evaluate the energy and economic performance of these two technologies and their temporal coupling. After the experimental optimisation of the aerodynamics of a small vertical axis wind turbine and the numerical optimisation of the electromechanical conversion using simulated data and deep learning, dynamic system models will be developed to be coupled to the LOHC process. The latter will integrate the loop: from intermittently generated or grid available energy to energy supplied on demand by storage in LOHCs or heat storage. The model will include hydrogen production by electrolysis, catalytic hydrogenation and dehydrogenation of LOHCs and conversion of hydrogen to electricity by an ICE-H2 or H2 turbine. Models of the hydrogen production and conversion elements will be taken from the literature. The dynamic system models of the catalytic reactors will be surrogate or reduced models based on numerical physical models developed during the project. The performance of the overall system will be evaluated using exergy and economic analyses for different scenarios of input winds, grid power availability and instantaneous energy cost of electricity.
