Many predications can be made about what will happen in the future. A common consensus is that energy usage will need to be more economical and efficient.
New technologies will be needed, for example, to enhance the electricity grid and thereby improve distribution of electricity to Germany’s cities. In particular, it will be necessary to operate such systems effectively.
In response to this possible need of the future, the industrial gases specialist Messer has developed a new cryogenic technology for the ‘AmpaCity’ project of the energy supplier RWE.
This makes it possible to use liquid nitrogen to cool superconducting cables down to -209°C. In the past it was only possible to cool the cables to -196°C. A difference of 13°C is enough to allow electricity to be transported through the grid almost lossless.
