Not sure, but the article does indicate they're working on reducing energy requirements with a view to making it lunar-feasible.
Engineers will tinker with the process by adjusting the electrical current and reagents to boost the amount of oxygen while trying to reduce the temperature needed to produce it. This will help bring down the energy required, which is already at a premium on the Moon.
