Rubenius refers to the concept as an "energy warehouse" and the plan is to use 1,000 megawatts of sodium sulfur (NaS) batteries funded with the help of Japan's Export/Import bank.

I can state that ProMexico and the rest of the Mexican Government is supporting 100% Rubenius and their Energy Warehouse Project in Mexicali, we have full confidence that the project will have a successful development and our President Felipe Calderon does as well.
I want to refer you to a video of the President Calderon where he personally presents the project to the press and media representatives in COP 16 event in Cancun last December 2010 [video is in Spanish].
