LOHC – Hydrogen transport made easy

How to use hydrogen, not oil, to power the economy

To achieve climate neutrality by 2050, Germany will need low-emission – if not zero-emission – solutions for transportation and industry. As part of a Kopernikus initiative called P2X, researchers are developing ways to safely store hydrogen in containers in atmospheric conditions. They use liquid organic hydrogen carriers, also known as LOHCs, which bind hydrogen reversibly and allow the subsequent separation of carrier material and gas through a special dehydrogenation unit. It is the only method for efficiently discharging this liquid storage. At the same time, however, the hydrogen needs to be upgraded to fuel cell quality.

Efforts to transform the energy sector have so far focused on increasing renewable generation capacity to lay the foundation for a future energy system. This has made the use of electricity in the heat and transportation markets all the more important, since electric power is an efficient means of generating and using renewable sources of energy.

Carbon-Filled Air as Raw Material Source

Carbon dioxide may be a greenhouse gas, but it can also be a raw material source in industries such as plastics processing and renewable energy generation, where it could gradually replace natural gas and crude oil. Capturing carbon dioxide directly from air provides several advantages for combatting climate change. While limiting the atmospheric concentration of CO2, it offers new opportunities in the chemical industry and in transportation and could dramatically lower harmful emissions by cutting into fossil fuel demand.
