The initial solar segment of Jiangsu province's first green hydrogen demonstration at the provincial levelhas been linked to the power grid, Shanghai Metals Market reported. At the Hydrogen Oasis Dafeng GreenHydrogen Demonstration Project in Dafeng, the first 100.48 megawatts of solar generation equipment have finished grid connection.

Electricity from this first-phase solar capacity will feed electrolyzers. Given that solar output rises and falls over the course of a day, a central question the demonstration addresses is how to reconcile electrolyzer operation with balancing supply and demand on the grid.

Solar panels produce direct current via the photoelectric effect, whereby light hitting a semiconductor creates an electromotive force. A power conditioner usually converts that output into alternating currentbefore it is dispatched to the transmission and distribution grid. Linking generation equipment to that gridlets the electricity produced enter the system, typically following trial operation and grid- side inspections, after which a project advances to gathering actual operating data

Hydrogen is expected to serve sectors where cutting emissions is hard, including steelmaking, chemicalfeedstocks, fuel cell vehicles and transport equipment. Green hydrogen is drawing interest as a possible substitute for fossil-fuel-derived hydrogen in these areas.

Possible revenue streams for a green hydrogen business include hydrogen sales, sales of oxygengenerated as an electrolysis byproduct, and electricity trading. Electrolyzer equipment and electricity makeup a large portion of total costs, and the price paid for electricity determines whether the business is viable.

tems to watch next include equipment connection after the first phase, the start of electrolyzer operations,and confirmation of customers for the hydrogen produced. Operating data from the demonstration willinform judgment when similar projects are scaled up.
