If the electrolyzer is using green electricity it will be good but it doesn't say if they are setting up the wind or solar plants to source that power. If they are using line power then its only 40% likely to be green energy produced.
The article says the current plan is to use line power.....so not perfect. But if it's more efficient then charging dc batteries it could be worth it, plus the grid could always change. Waste wise you wouldn't have to throw out any lead acid or lithium ion batteries when they finally die, which is an environmental win. Not sure if this is for only new facilities or not but if you do have to buy all new equipment and scrap all your old stuff that is an environmental loss.
