A review of electrolyzer-based systems providing grid ancillary services: current status, market, challenges and future directions

Frontiers in Energy Research, Год журнала: 2024, Номер 12

Опубликована: Фев. 8, 2024

Concerns related to climate change have shifted global attention towards advanced, sustainable, and decarbonized energy systems. While renewable resources such as wind solar offer environmentally friendly alternatives, their inherent variability intermittency present significant challenges grid stability reliability. The integration of sources requires innovative solutions effectively balance supply demand in the electricity grid. This review explores critical role electrolyzer systems addressing these by providing ancillary services modern grids. Electrolyzers traditionally used only for hydrogen production now emerged versatile tools capable responding quickly load variations. They can consume during excess periods or when integrated with fuel cells generate peak demand, contributing stability. Therefore, fulfill dual function producing end-user offering balancing services, ensuring greater economic feasibility. paper aims provide a comprehensive view systems’ provision including frequency control, voltage congestion management, black start. technical aspects, market, projects, challenges, future prospects using electrolyzers are explored.
