Chen et al. conducted an economic analysis of a renewable energy system using hydrogen produced by water electrolysis as an energy carrier to overcome the fluctuation of renewable sources. It was determined that a hydrogen-based energy storage system (ESS) is more advantageous economically than a conventional battery storage system.
The findings demonstrate that incorporating an energy storage system (ESS) can cut operational costs by 18 %. However, the utilization of a hydrogen storage system can further slash costs, achieving reductions of up to 26 % for energy suppliers and up to 40 % for both energy and reserve suppliers.
As with any energy storage system, pairing hydrogen energy storage with power generation systems like solar panels or wind turbines can reduce energy demand and therefore increase energy savings. This technology offers extra advantages like the ability to store larger amounts of energy for longer time periods.
The energy storage charging pile achieved energy storage benefits through charging during off-peak periods and discharging during peak periods, with benefits ranging from 699.94 to 2284.23 yuan (see Table 6), which verifies the effectiveness of the method described in this paper.
Based Eq. , to reduce the charging cost for users and charging piles, an effective charging and discharging load scheduling strategy is implemented by setting the charging and discharging power range for energy storage charging piles during different time periods based on peak and off-peak electricity prices in a certain region.
Some of the common challenges to opportunities of hydrogen storage are highlighted below. 1. Low Energy Density by Volume: Hydrogen has a low energy density per unit volume, leading to the need for efficient storage technologies to store an economically viable amount of energy. 2.
