The siren-like songs and the fairy tales of full electrification.

The siren call for full electrification lures people in with the simple and convenient-sounding claim that we only need to be able to provide enough renewable electricity and all energy issues will be solved, including mobility. However, even if the electrical grid is expanded up to a hundredfold, the systems generating the electricity would still have to be regulated to protect the grids from overload, because only as much electrical energy can be fed into the electrical grid as is being taken from the grid elsewhere at the same time. The enormous amounts of energy in the terawatt range that are to be generated by the planned wind turbines, which will then be stored by which technical solution, are being concealed. In the gigawatt to terawatt range, we really no longer need to talk about storage with batteries alone. The sustainable energy transition links the electricity sector with heat, gas products and fuels. Hydrogen is the link with Power-to-X.

The book is written with the background of my professional career in chemistry as well as in electrical engineering; supplemented with the background of the energy dialog EEZ Energie Energiewirtschaft Zukunftsenergien, which I founded myself on 05.07.1995. The professional basis is broadly diversified. In both cases, the employers noticed the very successful energy dialog EEZ Energie Energiewirtschaft Zukunftsenergien, so that the jobs arose from it. Since September 1997 in the project office of a regional energy supply company, responsible for the central control technology and automation technology for the energy centers. Changed departments in November 2019 with the project planning of electrical power grid construction. Since February 2003, initially commissioned with the tasks of setting up and expanding the regional hydrogen nucleus h2herten, then commissioned with the tasks of project acquisition and company acquisition, networking, market communication, in the team of the hydrogen user center h2herten. What drives me to write reports and books is my passion for highlighting the opportunities and possibilities in the potential grid of the energy transition, with hydrogen as an energy carrier; my ambition to build and expand a hydrogen infrastructure with the advertising of cross-industry service providers, with the identification of sustainable contributions and the resulting complementary competencies. I met the established companies in the energy market and their initial rejection of hydrogen as an energy source and the fuel cell as an energy converter with meaningful results of potential analyses, with the potential of Power-to-X sector coupling, the identification of unique selling points and with the complex project initiatives of the multi-layered interests of all those involved. With perseverance and patience, even initial skeptics of hydrogen as an energy source and the fuel cell as an energy converter were successfully won over to a complementary and sustainable infrastructure in the energy transition. I successfully contributed to the acquisition of members for the foundation of an advisory board for h2herten, from which the advisory board for the h2-netzwerk-ruhr emerged through expansion in 2008.
