We speak with Dirk Messner, Sacha Müller-Kraenner and Ove Petersen about the German hydrogen economy.

Exploring climate models in the 1980s sparked Alexander Voigt's passion for sustainability and belief in a global green economy. His career as a serial entrepreneur focuses on developing reliable and affordable CO2-free energy from renewable sources. With HH2E, Voigt's dream is becoming reality. This German green energy startup transforms surplus sun and wind energy into stable, price-competitive green hydrogen, aiming to install 4 GW of production in Germany by 2030. The company is also partnering with DHL and Leipzig Airport to launch a large-scale eSAF production project in Germany. Voigt founded Solon and Q-Cells in the 1990s, pioneering Germany's PV industry. Solon AG's 1998 IPO reached a market capitalisation of €5 billion, and Q-Cells became a global PV leader. In the 2000s, he co-founded Younicos AG and Lumenion, advancing off-grid renewables and energy storage. Passionate about cooking, hosting, and fly-fishing, Voigt is also a Greenpeace member. He seeks innovative ideas and talented individuals to join the renewable energy battle.
