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: Welcher Treibstoff ist der beste Energiespeicher?

Ob Auto, Flugzeug oder Schiff – die Grundlage der Mobilität ist heute ohne Zweifel der Verbrennungsmotor. Kaum eine andere Erfindung mündete in über 100 Jahren Entwicklungszeit in so viele verschiedene Bauvarianten. Ein Grund für den technischen Erfolg der Diesel- und Ottomotoren liegt in der hohen Energiedichte der Treibstoffe. Wie groß ist nun tatsächlich die Speichereffizienz von Erdöltreibstoffen im Vergleich zu Wasserstoff oder Lithium-Ionen-Akkus? read more

Energy question of the week: Which fuel offers the most efficient energy storage?

Whether on the road, by sea or in the air – the basis of modern transport systems is the internal combustion engine. Hardly any other invention has resulted in so many variants in just 100 years of development. One of the reasons for the technical success of diesel and petrol combustion engines is the high energy content of the fuel they burn. But how much energy do fossil fuels really contain, in comparison with hydrogen or lithium ion batteries? read more

Energie-Frage der Woche: Können blühende Algenteppiche unsere Treibstoffversorgung sichern?

Wie jeden heißen Sommer treiben gigantische Blaualgen-Teppiche über die Ostsee und verleiden Badegästen den Sprung ins kühle Nass. In den gelbgrünen Schwaden leben Cyanobakterien, die - einmal verschluckt - zu Vergiftungen führen können. Aber die Mikroorganismen können auch brennbare Kohlenwasserstoffketten, so genannte Alkane und Alkene, produzieren. Taugen sie dadurch nicht auch zur Herstellung von Diesel und Benzin? read more

Energy question of the week: Can we secure our fuel supply with the help of algal blooms?

Every hot summer, gigantic carpets of blue algae spread across the Baltic, much to the disapointment of seaside visitors looking for a quick dip in the cool water. Cyanobacteria inhabit the yellow-green plumes and can lead to poisoning if ingested. However, these same microorganisms can also produce flammable hydrocarbon chains known as alkanes and alkenes. Might they be suited to diesel and petrol production? read more
