Cost price of hydrogen energy photovoltaic sites in Azerbaijan

Do batteries affect the price of hydrogen production in a photovoltaic plant?

Hydrogen price depends on electricity and utilisation factor of the electrolyser. Batteries improve overall performance but penalize the system's economic balance. The aim of this work is to analyse the price of renewable hydrogen production in a stand-alone photovoltaic plant. The energy studied herein is generated in a photovoltaic plant.

How much does green hydrogen cost?

The sensitivity analysis in the case of a 1 MW plant was carried out with a range of electricity cost starting from $0.0198 to $0.0292, and the utilisation factor ranging between 11.49% and 39.12%. The possible combinations between these values resulted in green hydrogen prices, whereby the cheapest stood at $2.66 and the most expensive at $6.83.

What are the costs associated with hydrogen production?

Costs linked to hydrogen production, such as the amount of water required, the price of electricity, and the efficiency of the system, are also taken into account. Apart from these computations, the operational and maintenance expenses as well as the amortisation are estimated per year as a percentage of the investment in the electrolyser plant.

Are solar-energy systems a viable alternative to hydrogen production?

Solar-energy systems definitely present the attractive and economically viable renewable alternative for hydrogen production as has been established [6, 16], although the penalty incurred by their intermittent character on overall system performance must always be considered for optimisation.

Will hydrogen prices decrease over the years?

It is widely believed that they will lower in price over the years, mainly due to the decrease in renewable energy production costs, to economies of scale, research, projects already finished, and advances in technology. The latest Hydrogen Council report claims that the cost of hydrogen solutions will decrease in the next decade.

How many cases does a photovoltaic source have?

On each scale, the photovoltaic source is considered on its own and with storage, which creates four cases in total. The efficiency of the electrolysis plant provides the starting point for each scenario.
