Another advantage of hydrogen storage is the flexible combination of charge power, discharge power and storage capacity, because each of them is determined by separate component. The major drawbacks of hydrogen storage are the high investment cost and low round trip efficiency (around 35%) [14] .
For such intermittent balancing, battery energy storage and hydrogen energy storage provide a flexible, adequate solution [2]. Battery storage achieves a fast response time and a high round-trip efficiency ( ≈ 80 %, as opposed to ≈ 35 % for hydrogen storage), which makes it suitable for short-term energy storage (i.e. from seconds to …
