Jan Oliver Löfken

Energy journalist Jan Oliver Löfken writes among other things, for the Technologie Review, Wissenschaft aktuell, Tagesspiegel, Berliner Zeitung and P.M. Magazin on issues involving energy research and industry. For DLR, he answered the Energy question of the week during the Year of Energy 2010.

Currently, Jan Oliver Löfken writes in the DLR Energy blog on current topics related to the energy turnaround. He considers the contributions that research can make to a secure and affordable energy supply. The energy transition is a social challenge - a project of the century, as noted by Environment Minister Peter Altmeier. In the DLR Energy Blog, Jan Oliver Löfken discusses the outlook of the power supply and what can set the course for politics and the economy today.

Energie-Frage der Woche: Kann Sonnenlicht Wasser direkt in Sauerstoff und Wasserstoff spalten?

Solarzellen können Sonnenlicht immer besser direkt in Strom umwandeln. Trotzdem reichen sie in ihrer Effizienz längst nicht an die der natürlichen Photosynthese heran. Mit ihrem Chlorophyll beherrschen Grünpflanzen das Kunststück, aus Kohlendioxid, Wasser und Sonnenstrahlen energiehaltige Moleküle wie Zucker oder Stärke zu produzieren. Wäre es daher nicht sinnvoll, diesen natürlichen Prozess für eine technische Energiegewinnung zu nutzen? read more

Energy question of the week: Can sunlight be used to split water directly into oxygen and hydrogen?

Solar cells are good at converting sunlight directly into electricity. However, they come nowhere close to the efficiency of natural photosynthesis. Using chlorophyll, green plants have mastered the art of producing energy-rich molecules such as sugar and starch from carbon dioxide, water and sunlight. Would it not make sense to harness this natural process to generate energy? read more
