The production of biomethane from kitchen waste offers an as yet untapped potential for the energy transition. So far, only a small portion has been used for this purpose.

How can the consequences of storms and rising water levels in the tidal river Elbe, resulting from climate change, be minimized? This is what the TU Institute of River and Coastal Engineering is investigating for several time frames up to 2200.

By 2050, the global water demand is expected to increase by 55 percent, much of which is attributed to agriculture. No wonder, since a good 40 percent of all food worldwide is grown on artificially irrigated land. Any savings in agricultural water use can free up water for other pressing needs like drinking water. A TU Hamburg-project shows how water and fertilizer use can be drastically reduced with a new cultivation concept.

Global climate targets call for rapid decarbonization of energy generation and increasing integration of renewable energies. But the wind doesn't always blow or the sun doesn't always shine. To ensure a secure supply, electricity, gas and heat grids must be coupled.
