en.Wedoany.com Reported - One of the most attractive scenarios for solar hydrogen is building large PV bases in deserts, Gobi regions and plateaus, then producing green hydrogen on site. These areas often have strong solar resources and land conditions suitable for large-scale development, making them important testing grounds for Photovoltaic Hydrogen Production.

The solar resource advantage is clear. IEA data show that global solar PV additions surpassed 600 GW for the first time in 2025, making solar PV the power technology with the largest installed capacity globally. China alone commissioned nearly 370 GW of solar PV in 2025, remaining a major driver of global expansion.

Desert and Gobi solar hydrogen has three advantages. First, strong solar resources help lower renewable electricity costs. Second, large land areas support scale. Third, some regions are close to coal chemical, steel, non-ferrous metals and ammonia industries, creating potential hydrogen demand.

However, challenges are significant. Water is the first constraint, because electrolysis requires reliable water supply. Desert projects must assess water sustainability, permitting and treatment cost. The second challenge is transport. If users are far away, hydrogen compression, liquefaction, pipelines or conversion into ammonia or methanol must be included in cost models. The third is equipment adaptability: heat, sand, large day-night temperature differences and altitude affect PV modules, electrolysers, compressors and control systems.

Large desert projects should not pursue maximum scale first. A more practical path is to build medium-scale demonstrations around industrial users or chemical parks, validating solar output, electrolyser flexibility, water supply, hydrogen storage and transport cost before expansion. For remote bases, green ammonia or green methanol may be more transportable hydrogen-derived products.

The value of large-base Photovoltaic Hydrogen Production is not only producing hydrogen, but converting low-cost solar resources in remote regions into storable, transportable and tradable industrial energy products.
