„I am a realist with a slight tendency toward optimism“, says Nils Aldag. Over the years, however, he has taken on the role of an optimist at Sunfire, says the co-founder and CEO of the Dresden-based electrolysis specialist. This sentence fits the 36-year-old very well. Especially because in 2010, when Sunfire was founded, it still looked as if Aldag and his co-founders were ahead of their time with the topic of green hydrogen. But the tide has since turned: „We are moving in an industry where all arrows are pointing upward“, says the Sunfire CEO. Over the past 24 months, he says, there has been a significant acceleration in the topic of renewable energies.
