German car maker Daimler and industrial gases company Linde plans to invest tens of millions of euros in hydrogen fuelling stations in Germany, two people familiar with the matter said.

They told Reuters on Tuesday the plan to build one or two dozen stations in the country is to be announced in Stuttgart, where Daimler is headquartered, on Wednesday.

Carmakers including Daimler, Toyota, Ford and General Motors joined forces in late 2009 to develop fuel cell vehicles.

Linde and Daimler as well as utility EnBW, Austria's OMV and France's Total are involved in setting up a fuelling station network that will reach from the Alps to the North Sea.
