* E.ON active in power market, Thyssenkrupp supplies plants
* 600 MW of hydrogen capacity to be tapped in Germany, UK
* Saves wasting power, earns money in wholesale market
* But it is early days for hydrogen adoption, eco-systems

FRANKFURT, June 30 (Reuters) - Germany’s E.ON and Thyssenkrupp will make hydrogen available to the wholesale power market by pooling the output of 150 small electrolysis plants, the companies announced on Tuesday.
The utility and a plant building arm of the conglomerate have formed a venture that will use a virtual power plant (VPP) to pool some 600 megawatts (MW) of power from electrolysis units in Germany and Britain, they said.
The system has been tested at a 2 megawatt (MW) pilot plant in Duisburg and is ready to be for scaled up.
“With our expertise in all aspects of the energy market, we are also succeeding in breaking down a barrier to the useful application of hydrogen in generating electricity,” Stefan Hakansson, E.ON’s global director City Energy Solutions and head of E.ON Business Solutions, said.
Germany and the European Union are pushing hydrogen as a clean fuel to meet climate targets via electrolysis in a process that passes electricity from wind and solar sources through water to extract carbon-free hydrogen.
The operating principle of E.ON’s VPP is to shut down hydrogen output at the plants at times of high power demand, allowing green power to flow to consumers as now, and, conversely, to raise hydrogen production if there is surplus power.
Electrolysis producers can thus market their flexibility to consumers via E.ON’s online platform.
Germany recently dedicated 9 billion euros ($10.08 billion) for the build-up of hydrogen economies.
Many schemes are starting up and brokers and exchanges are beginning to study possibilities of euro-denominated hydrogen contracts.
But some banks say there is too much hype around hydrogen as major commercialisation is years away and the technology is still costly and unproven. ($1 = 0.8928 euros) (Reporting by Vera Eckert, editing by David Evans)
