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
