Nuclear and Wind to Produce Hydrogen

That's an idea two scientists from Canada are exploring:

In the system envisioned by Alistair Miller and Romney Duffey of Atomic Energy of Canada, nuclear power plants would be paired with wind turbines to power electrolysis cells, which make hydrogen by passing an electric current through water.

Wind on its own is too variable, Miller says, leaving electrolysis equipment frequently idle and driving up costs. "The economics just don't work," he says. "It produces very expensive hydrogen."

Pairing it with nuclear would keep the equipment operating closer to full capacity and bring the cost down, he says. A bonus is that when the wind is strong and electricity demand is high, excess power can be sold at a profit to the grid. This means that, unlike traditional electricity-based hydrogen production, Miller's system actually makes hydrogen cheaper as the cost of electricity goes up.

We're always saying there's no reason nuclear and renewables can't work together. It's encouraging to find a real world example. Thanks to AltEng for the pointer.
