Seat teams up with water company to power cars with sewage

Updated: 


Spanish car manufacturer Seat has joined forces with water management company Aqualia to fuel vehicles from biomethane.

The Smart Green Gas project sees renewable biofuel obtained from waste water used in compressed natural gas vehicles.

Seat has provided Aqualia with two Leon TGI vehicles to perform the testing of the biomethane product and then verify the entire production chain until the fuel is collected and used.

For this primary testing process, the two companies have started work at Aqualia's plant near Cadiz.

Dr Matthias Rabe, Seat's vice-president for research and development, said: "With this development and collaboration project with Aqualia, Seat has become the first brand in the country's automotive sector to use 100% Spanish biomethane obtained from waste water.

"Fostering the creation of renewable alternative fuels, which help promote future environmental improvements and the long-term use of vehicles in cities are an integral part of Seat's compressed natural gas strategy."

The Smart Green Gas initiative aims to achieve energy security and efficiency by providing more autonomy and sustainability to cities around Europe that use waste water to create biofuel.

Aqualia's general director, Félix Parra, said: "We are working to change the current paradigm, leaving behind the model in which treatment implies a significant energy cost.

"Developing the Smart Green Gas project with a medium-sized waste water treatment plant could potentially lead to the daily production of a million litres of biofuel, enough to power more than 300 vehicles. This would enable cities to fuel their network of urban buses, bin lorries, police cars or ambulances, among others."
