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

03. September 2010, 15.37
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?

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

02. August 2010, 10.01
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?
