Stefan Dürr, CEO and founder of Ekotechnika, participated in a March 2021 interview with the Zentrum Wasserstoff Bayern, discussing hydrogen as an opportunity for companies. Dürr described hydrogen as "extremely versatile to produce and extremely versatile to apply," comparing it to a battery for renewable energy. He explained that electrolysis uses electricity to split water into hydrogen and oxygen, with the hydrogen storing much of the energy used, and that a fuel cell can reverse the reaction to release energy, producing only water as a byproduct. Dürr noted that electrolysis has an efficiency of 60 to 70 percent, with total losses of about 50 percent along the chain, but added that hydrogen can be produced in locations where power lines cannot reach. Dürr also addressed the relevance of hydrogen for small and medium-sized enterprises, stating that the technology is about more than just powering vehicles. He said that companies in other sectors have realized they can apply hydrogen technology to industries involving heat generation, such as combined heat and power, which connects to heating and energy supply. Dürr expressed that a mix of solutions will be needed to avoid CO2 emissions, advocating for "the and and and against the or" approach rather than focusing on a single technology.
