Buses in Rennerod, Germany, will be powered by an environmentally friendly hydrogen energy system next year. The system was designed and implemented by an international team of companies using technology that is now commercially available.
GFW will produce hydrogen fuel using advanced alkaline electrolysers from GreenHydrogen, which convert electricity into hydrogen, at two different locations.
One electrolyser will be placed next to an existing Fuhrländer FL1000 wind turbine. It will produce green hydrogen which will be compressed using a Clantech containerized solution, compressing the hydrogen to 300 bar before it is stored in an “H2Pod Virtual Pipe Line” from Calvera. This solution facilitates the easy distribution of green hydrogen to customers, the first of which is the Rennerod bus system, which operates neighbourhood buses powered by fuel cells. It also allows the fuel to be produced and consumed locally, which eliminates transportation costs .
Another electrolyser will be installed at the GFW facility, where it will be powered by an existing solar farm. There will be 15 additional tracker systems installed in the solar farm that will deliver 300 kW. The hydrogen produced by GreenHydrogen’s alkaline electrolysers will then be stored in Calvera units at different pressure (300/450/900 bar) and, finally, be distributed from the hydrogen refuelling station (SIDE H HRS) supplied by Clantech – at 350 and 700 bar.
The idea for the hydrogen delivery system came from GFW owner Jürgen Furhländer, who said, “Wind turbines and solar farms that soon will, or already have, run out of guaranteed feed-in tariff need to be revitalized and turned into future profit machines – not just being dismantled when the tariff is too low.”
“Upgrading pure green electricity to green fuel in the shape of hydrogen will be a key factor in the future energy eco-system, and will help decrease dependency on imported fossil fuel,” said Henrik Steen Pedersen, GreenHydrogen’s Executive Vice President of Sales.
GFW says it is open to supplying the “hydrogen option” to its existing and new clients. The company expects to continue working as a supplier of similar solutions, as well as working with local governments to obtain the necessary approvals.
