LNGCON 2023: Methane Electrolysis Converts LNG to CO2-free Hydrogen

On March 6 and 7 at International LNG Congress 2023, more than 350 companies will discuss key challenges of the LNG industry – from transportation and storage infrastructure to use as a fuel or by end users. Graforce will introduce methane electrolysis (plasmalysis) – a game changing technology, which converts LNG into hydrogen. This allows large gas users to switch to clean-burning hydrogen without changing their energy supplier or method of transporting.

"We cannot do completely without fossil fuels yet. But the EU can still achieve its decarbonization targets if LNG, LPG or natural gas are no longer burned but converted into hydrogen and solid carbon with the help of green electricity and our hydrogen plants," said Dr. Jens Hanke, CTO of Graforce.

In the modular plasmalysis plants, a high-frequency plasma field, generated by renewable electricity, splits hydrocarbons such as methane into their molecular components: hydrogen and solid carbon. Compared to water electrolysis, plasmalysis requires only one-fifth the energy to produce the same amount of hydrogen. A single 20-megawatt plant can convert about 70,000 metric tons of LNG into hydrogen per year and save about 200,000 metric tons of CO₂.

The hydrogen can be used for emission-free electricity and heat generation or in the chemical industry. Since the CO₂ is sequestered in products over the long term, this technology is also the first market-ready alternative to carbon capture storage.

Cooperation for electricity-autonomous combined heat and power generation

In January 2023, Graforce entered a cooperation with Kawasaki Gas Turbine Europe. Within the plant solution, carbon-free hydrogen is produced from biomethane, natural gas, LNG or LPG. This is converted to electricity in Kawasaki's hydrogen gas turbine and reused in the plasmalysis to produce hydrogen. Thus, CO₂-free electricity and high-temperature heat is generated. Once started, the whole system requires no further electricity.

About Graforce

Graforce is a German hydrogen technology company. Their power-to-X plants produce carbon dioxide free or carbon dioxide negative hydrogen and synthetic feedstocks – with highest efficiency and lower infrastructure costs in the multi-megawatt range. Thus, Graforce decarbonizes fossil energies, industrial sectors and the heat, transport and building sectors. The company is currently in the process of expanding its strategic partnerships to quickly scale its hydrogen technology worldwide. www.graforce.com/EN
