SUSTAINABILITY
50 addition to fleet vehicle parks for EV charging at multi storey car parks , shopping centres , parking for buses , ambulances and police cars ; for powering trains on the systems of many countries ; and for powering heavy goods vehicles . Hydrogen fuel cells generate electricity by combining hydrogen and oxygen . They are reliable and quiet , with no moving parts , have a small footprint , high energy density and release no emissions – when running on pure hydrogen , their only by-product is water . Fuel cell facilities can , therefore , produce hydrogen when electricity is cheap , and later use that hydrogen to generate electricity when it is needed .”
Green ammonia , using wind or solar power to produce it , is another avenue that Siemens is exploring . It has a £ 1.5m pilot project in Oxfordshire employing ammonia as a new form of energy storage . The potential advantage of ammonia over other emerging storage technologies is that volume production is already proven and scalable plus it can be transported using existing technology and hardware , even the existing gas
