Several green hydrogen storage projects are underway worldwide, as shown in Table 1. Energiepark Mainz is funded by German Federal Ministry for Economic Affairs and Energy to investigate and demonstrate large-scale hydrogen production from renewable energy for various use cases.
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.
Opportunities Hydrogen storage offers several opportunities that make it an attractive option for energy storage and distribution. Some of the opportunities for hydrogen storage are. 1. Decarbonization: Hydrogen storage can improve energy security by enabling the storage and distribution of energy from diverse sources.
A robust distributed model for power and hydrogen-based multi-microgrids is proposed in , where hydrogen storage systems play an important role in minimizing the operation cost of multi-microgrids by making more efficient use of surplus wind energy generation.
Additionally, the long-term stability and safety of the aquifer must be carefully assessed to ensure that hydrogen can be stored safely and securely. Another storage technology is using depleted oil and gas fields, which are considered potential storage options for hydrogen due to a large storage capacity for hydrogen .
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.
