Hydrogen from Natural Gas Without CO2 Emissions Main 1

KIT and Wintershall Dea Launch Collaboration on Climate-friendly Industrial-scale Methane Pyrolysis

Methane pyrolysis will allow for the future climate-friendly use of fossil natural gas: Methane is separated into gaseous hydrogen and solid carbon that is a valuable material for various industry branches and can also be stored safely. This may be a key component of future climate-neutral energy supply. Researchers of Karlsruhe Institute of Technology (KIT) have developed a highly efficient process for this purpose. Together with the industry partner Wintershall Dea, this process will now be further developed for use on the industrial scale.

In the current energy debate, hydrogen is increasingly considered a key to the success of the energy transition. Experts of the International Energy Agency IEA calculated that admixture of 20% of hydrogen in the European gas grid could reduce CO2 emissions by 60 million tons per year. This corresponds to about the amount emitted by Denmark in a whole year. “Direct thermal cracking of methane and other hydrocarbons is a way to produce hydrogen from natural gas without direct CO2 emissions,” explains Professor Thomas Wetzel of KIT’s Institute of Thermal Process Engineering. For this purpose, his team, in cooperation with the Institute for Advanced Sustainability Studies e.V. in Potsdam, developed a process for the continuous decomposition of methane in a bubble column reactor filled with liquid metal to produce hydrogen and solid carbon. As a pure solid, carbon can be stored safely and be used in many industrial sectors. Hydrogen is a clean source of energy and can be used for the production of electricity and heat and in the mobility sector or in industrial processes, such as for the production of steel.

Research Collaboration with Wintershall Dea

In a joint project scheduled initially to run for three years, KIT and its industry partner Wintershall Dea plan to lay the foundations for future industrial use of methane pyrolysis within the next three years. “There are huge quantities of natural gas worldwide and it can be used in a climate-neutral way. We now want to study how this can be achieved efficiently and use the results for processing large quantities of gas later on,” Wetzel says. “We are looking forward to this collaboration and are confident that we can make a major contribution to sustainable energy supply in the future.” Hugo Dijkgraaf, Member of the Board and Chief Technology Officer of Wintershall Dea, says: “The perspectives we are creating as part of our cooperation with KIT show that natural gas is fit for the future. Natural gas already is the cleanest conventional source of energy. Yet, it can become even more climate-friendly in the future, if we separate the CO2 and use the natural gas to produce hydrogen.”

Prize-winning Methane Pyrolysis Research

In 2018, research of KIT and the Institute for Advanced Sustainability Studies e.V. relating to methane pyrolysis was granted the Innovation Award by the German Gas Industry and additionally won the audience award of the ERDGAS 2018 Zukunftswerkstatt, an event staged by the Zukunft ERDGAS industry initiative. “Cutting-edge gas technologies are given a stage at the Zukunftswerkstatt and the Innovation Award competition of the German Gas Industry,” says Dr. Timm Kehler, Chairman of the Zukunft ERDGAS industry initiative. He greatly welcomes the launch of a joint project by KIT and Wintershall Dea to put decarbonized natural gas on the market. “We need green gas and such forward-looking partnerships in order to swiftly overcome the challenges of climate change,” Kehler says. Zukunft ERDGAS also sponsors the Innovation Award along with other industry associations. Both events are supported by Wintershall Dea.
