The world’s first hybrid wind park able to deliver energy at a constant rate over 24 hours or at a rate matching the market exactly (i.e. delivering most when prices are highest) was opened today with a ceremony attended by the Minister-President of the German State of Brandenburg, Matthias Platzeck.
The plant does that by producing hydrogen when they don’t want to feed in all their electricity to the grid with a 500 kw electrolyser. Then they fire a gas turbine to get back the electricity when the market price is higher.
Congratulations to Enertrag for pulling off this interesting innovation.

Hydrogen storage for wind energy

The answer is to add the capability of hydrogen storage as Enertrag did with their recently opened first hybrid wind park. [...]

[...] In a brochure about their renewable plans Deutsche Bahn explains that they are already at over 20 percent renewable and want to get to 35% until 2020 and 100% until 2050. They also note that their railway traffic already runs to 90 percent on electricity, while cars will have a long way to go to achieve that rate, so rail is by far the most climate friendly mode of transportation. They also note that they have helped build the world’s first hybrid wind project (with hydrogen storage), which has started production in 2011. [...]
