However, the presented studies ignore the influencing factor of battery life, or set it to a constant value, which may significantly affect the economy of capacity configuration. Battery life, influenced by depth of discharge (DOD), state of charge (SOC), and other variables, varies based on BESS''s scheduling strategy and operating conditions.
However, the majority of available reports on the battery value chain rely solely on the material balance (MFA) and neglect the causal links and feedback loops pertaining to a complex system, such as the interactions between the price and demand, among others . In the "criticality" studies, the supply risk and its impact on the battery value chain (vulnerability) is

Clean hydrogen value chains consist of three key stages, summarised in the diagram below: production, distribution (including storage), and end-use applications. 1. CLEAN HYDROGEN PRODUCTION.
Hydrogen has a lower heating value of 33.36 kWh/kg, i.e., more than a hundred times batteries specific energy. Therefore, hydrogen storage systems can complement batteries and be used in renewable sources-based plants as a long-term storage system, while batteries would act as short and medium-term storage system.
Hydrogen has an important potential to accelerate the process of scaling up clean and renewable energy, however its integration in power systems remains little studied. This

How to calculate hydrogen ventilation requirements for battery rooms. For standby DC power systems or AC UPS systems, battery room ventilation is calculated in accordance to EN 50272-2 Standard. Battery room ventilation flow rate is calculated using the following formula: Q = v * q * s * n * I gas * Cn / 100. Q = ventilation air flow (CMH) v = necessary hydrogen dilution factor

Lorsqu''elles sont alimentées par batterie, les voitures utilisent directement l''énergie électrique provenant de la batterie elle-même. En revanche, quand l''hydrogène est utilisé comme vecteur, il n''est pas utilisé directement car il doit d''abord être transformé en énergie électrique afin d''alimenter le moteur.

Organized hydrogen markets or hydrogen exchanges still do not exist, but according to [63] they must be created along with the hydrogen transmission grid (so-called "hydrogen backbone") to support a new hydrogen economy. The hydrogen market is expected to be halfway between the electricity and the gas market in terms of volatility and temporal
Hydrogen has an important potential to accelerate the process of scaling up clean and renewable energy, however its integration in power systems remains little studied. This paper reviews the current progress and outlook of hydrogen technologies and their application in power systems for hydrogen production, re-electrification and storage.
Figure 3 shows the different stages of losses leading up to the 30% efficiency, compared to the battery’s 70-90% efficiency, since the stages of losses are much lower than hydrogen. Since this technology is still under development and improvement, it is lagging in streamlining its production.
NREL has revealed that the potential price of hydrogen is about 3 to 10 USD/kg, while the most common price of hydrogen fuel is 13.99 USD/kg . Besides, developing on-board hydrogen applications can also help to reduce the need to increase the capacity of grid infrastructure for vehicle charging.
Hydrogen contains 33.33 kWh energy per kilo, compared to 12 kWh of petrol and diesel . However, storing the same amount of hydrogen requires a larger volume. The development of hydrogen storage technologies is, therefore, a fundamental premise for hydrogen powered energy systems.

The proportion of the hydrogen emitted from a hydrogen energy system during production, transport or at the point of use may range from 0.2 up to 10% .
For hydrogen fuel vehicles, the hydrogen in the tank must be reconverted into electric power, which is done through fuel cell. According to the U.S. Department of Energy, the fuel cell technology has the potential of achieving 60% of efficiency, with most of the rest of the energy lost as heat (U.S. Department of Energy, 2011).
