About us

Without energy, there is no wealth. Without energy, there is no development. Energy is the driver for innovation and is itself the object of innovation. Energy concepts which are economically, ecologically and socially sustainable are intrinsically tied to the usage of renewable energy and to enhancing energy efficiency. This is what we at ZSW are working for: photovoltaics, regenerative energy carriers such as hydrogen and methane, battery and fuel cell technologies as well as economical analyses of energy systems.
