That's far too optimistic about storage. For small off-grid systems, you need ~5 days of battery capacity to ride out lack of wind/sun. On a large scale you'll need less because you can move power from place to place.
But still. Sun is down half the day and wind speeds can be low in areas hundreds of miles wide. Its obvious they will need at least a day of battery capacity, probably more. Not hours.
Solar and wind are great. Many areas in the US have hours long periods during the day where power is 100% renewable. But batteries are way too expensive and I don't like when politicians make laws based on predictions 15+ years in the future.
