We suggest that the major European cities should buy “green energy” from the wind power generated by wind farms and produce green hydrogen with electrolysis. Later on, as water electrolysis units of one or more megawatt scale become available, we will provide assistance in building independent, self-service urban hydrogen farms. In the meantime, we are ready to supply various types of hydrogen-driven vehicles (buses, passenger cars, trolleys and transporting vehicles). We help in building re-fuelling stations in cooperation with the local transport company, universities, colleges and other connected companies. We are urging the introduction of Hungarian innovation and bring the American hi-tech know-how in the European cities. In order to guarantee clean air and an even hydrogen supply, we recommend and facilitate the establishment and expansion of hydrogen storage and transportation facilities. In case of separated operation from the network, we suggest the cooperation of more cities in order to help each other managing capacity and storage of wind power plants and containers.
