Berlin-based technology company Graforce has introduced a unique technology: the efficient extraction of hydrogen from industrial wastewater by plasma decomposition to save resources, and then mixed with biogas to produce hydrogen-rich compressed natural gas (HCNG) – an economy Environmentally friendly automotive fuels are also suitable for the production of electricity and heat. This technology not only converts pollutants in wastewater into valuable energy, but also reduces emissions (carbon dioxide, carbon monoxide, hydrocarbons) by 30%. 60%, NOx emissions can also be reduced by up to 60%. Graforce partners include car manufacturers Audi and Berliner Wasserbetriebe.
Dr. Jens Hanke, founder of Graforce, said at the launching ceremony of the demonstration plant in Berlin today: 'We have developed technologies that clean wastewater and produce low-cost, low-emission fuels. This helps solve two pressing problems at the same time: Air pollution And wastewater treatment. '
Low-emission, economical fuel
Graforce's demonstration plant in Berlin uses a plasma decomposition process to produce hydrogen. The process uses electricity to break down wastewater from biogas plants, sewage treatment plants and industrial plants into oxygen and hydrogen, and then mixes hydrogen with biogas to produce HCNG. HCNG is available. Used as natural gas vehicles, district heating and fuel for gas-fired power plants. The only waste left is pure water and oxygen. The use of plasma decomposition to produce hydrogen is 50-60% cheaper than conventional processes.
Audi tested methane production from wastewater in its e-fuel project
German carmaker Audi has been looking for alternative synthetic fuels for many years. One of the biggest challenges for e-fuel production is the waste water produced by biogas plants, which is very expensive to clean or dispose of. Integrating plasma decomposition technology into Audi's The e-fuel plant, which reuses wastewater for hydrogen production and purifies it, allows Audi's systems to be used more efficiently. Head of Audi Renewable Fuels Project Management, Dr. Hermann Pengg, CEO of Audi Industriegas GmbH Explain: 'Graforce's plasma decomposition is an important contribution to low-emission fuel production, while also improving the economics and efficiency of biogas and power-to-gas plants.'
