Feasibility study report on photovoltaic energy storage and hydrogen production epc

Why do solar PV systems have a lower capacity requirement?

This is because the construction of the PV system is the main contributor to metal depletion in SPV (52 %) and the PV system capacities are determined by the solar-utilisation hours, resulting in lower capacity requirements in regions with higher utilisation hours.

Does a different PV configuration affect hydrogen production compared to BPV & GPV?

Hydrogen production with different PV configurations across the selected regions The results in Fig. 6 and Fig. 7 reveal that the SPV configuration has lower impacts for 11 out of 18 categories compared to BPV and GPV, including climate change, resource depletion and the impacts related to water, soil and air pollution.

Could solar energy be the future of hydrogen production in China?

Worth $4.5bn, the plant will be producing 50 kt of hydrogen annually in polymer electrolyte membrane (PEM) electrolyser with the capacity of at least 500 MW (Martin, 2023). Consequently, solar energy holds significant potential for China's renewable hydrogen production.

Is China a leader in photovoltaic power generation?

Furthermore, it is a global leader in photovoltaic (PV) power generation (BP, 2022). Leveraging the latter, China is currently building the world's largest “green” hydrogen plant that will be supported by a 3 GW solar (and wind) power infrastructure.

Does a PV system reduce human toxicity?

Furthermore, recycling of the PV system reduces non-cancer human toxicity by 2–18 % and terrestrial ecotoxicity by 3–20 %, but increases human toxicity-cancer, freshwater and marine ecotoxicity by 4–38 %.

Which GPV configuration is best for hydrogen production?

Therefore, producing hydrogen in the GPV configuration is economically the best option across the regions. Generally, deploying PEMWE hydrogen production in Inner Mongolia would have the lowest LCC and LCOH across the configurations, while Zhejiang would be the most expensive option.
