The future of seawater desalination

People around the world are increasingly dependent on drinking water from seawater desalination plants. Water is a scarce resource. And it will probably stay that way because while in some regions of the world per capita consumption is steadily increasing,…

Wind turbine blade recycling

Rotor blades are robust, which makes recycling difficult. So far, it has hardly been possible to do more than store them in landfills. A modern rotor blade measures 70 meters in length, up to 90 meters for offshore systems, and…

Hydrogen storage options

Hydrogen storage can basically take place in a gaseous or liquid state, but also in chemically bound form, in metal hydrides, or via adsorption. Hydrogen is gaseous under ambient conditions and is the lightest element in the periodic table with…

Tesla Solar-Roof

Seen from the ground Tesla´s Solar-Roof is indistinguishable from the usual clay or slate bricks, with the difference that they produce electricity. With a seamless design, each tile looks great up-close or from the street. Tesla would like to continue…

Hydrogen: Hype or Hope?

Many experts have high hopes for hydrogen to make the world less dependent on fossil fuels. There are significant challenges between the potential of hydrogen and its use in different sectors. In individual road transport, an electric car is a…

Challenges of Electric Vehicle Battery Recycling

With the change in traffic to electromobility, the number of batteries to be reused will increase sharply. The raw materials it contains are valuable and must be recycled for a sustainable future. However, the recycling process leads to some challenges…

From energy crisis to raw material crisis?

For a transition to green energy technologies, raw materials play a major role. As with other high-tech products, increasing quantities and more and more different metals are required for renewable energy systems and storage systems. But which ones could lead…
