Well, the issue is bad wording on the reporter's part. I think that what the text says is not what the text ought to say. But here's the text:

generating electricity and storing it in molten salt

So, something is being stored in molten salt. What? Well, "it" is being stored in molten salt. And what does that "it" refer to? Well, the electricity that was just generated.

Now, clearly they are using solar power to generate electricity, and clearly energy is being stored in some manner. That makes sense. But the reporter's wording is just terrible.

Although I read the article I forgot the part you quoted and you are correct. The reporter says that electricity is being stored in molten salt.
