    Storing up the sun

    Experts say that new storage technologies like batteries and hydrogen are not relevant to Germany’s switch to renewables right now. But if grid expansion work continues to stagnate and if aging pumped storage systems stop making economic sense, then things could change very quickly indeed.

    Desertec project

    A mirage in the desert?

    Large European companies were planning to invest hundreds of billions of euros in transporting solar energy from North Africa to Europe as part of the Desertec initiative. But now there is disagreement as to what strategic direction the project should take. Could this be the end of the road?

    Lidar technology

    Lasers: 1, Gusts: 0

    Sudden gusts of wind make rotor blades spin too fast and put engines under a lot of strain. A new early warning system that recognises powerful movements of air can turn blades out of the wind in good time and reduce loads.

    Offshore rescue

    Who do you call in an emergency?

    Long distances from land and difficult weather conditions make rescue missions to offshore wind farms a real challenge.

    BMW i3

    e-cars can be fun

    The BMW i3 is a compact, lightweight electric car made of carbon fires, aluminium and plastic. Combining great driving performance with the high quality you can expect of BMW and an ultramodern design, the i3 is set to become a role model for e-mobility.

    Air pollution

    Smog fuels storms

    Heavy air pollution in large Asian cities will do long-term damage to the climate. A more immediate problem, however, is that the dirt seems to be exacerbating storms over the Pacific Ocean a new research has found.

    Changes in the geothermal order

    The US still leads the field in installing geothermal energy systems. But according to the country’s Geothermal Energy Association (GEA), that could soon change.

    Offshore technology

    Profound progress

    Large offshore turbines are mostly installed on complex structures. Cylindrical monopiles can only support small turbines, as they cannot be driven deeply enough into the seabed. But thanks to new drilling technology, a solution is now on the way.

    Marine environment study

    Offshore teamwork

    If offshore wind power is to play a bigger role in Germany’s energy mix, then it’s going to have to become a lot cheaper. With this in mind, the three companies operating North Sea wind farms – Germany’s Eon, Denmark’s Dong Energie, and Austria’s Strabag – are planning to reduce their respective project costs by cooperating on the environmental studies that they each have to carry out.
