  • Techno-economic assessment of cooperation of hybrid renewable energy sources with hydrogen storage

    Publication

    The paper presents a technical and economic analysis of the power supply for a model industrial facility with the use of the most promising renewable energy sources (RES), supported by a hydrogen energy storage. This scenario was compared with the variants of supplying the facility directly from the grid and from RES without energy storage. A strategy was proposed for powering the plant aimed at maximising self-consumption of self-generated...

  • Techno-economic evaluation of combined cycle gas turbine and a diabatic compressed air energy storage integration concept

    Publication

    - ENERGY - Year 2023

    More and more operational flexibility is required from conventional power plants due to the increasing share of weather-dependent renewable energy sources (RES) generation in the power system. One way to increase power plant’s flexibility is integrating it with energy storage. The energy storage facility can be used to minimize ramping or shutdowns and therefore should lower overall generating costs and CO2 emissions. In this article,...
