Wartsila to supply biogas-to-biomethane plant in the UK
Finnish tech group Wartsila announced on March 14 it was supplying a biogas-to-biomethane plant to UK waste management group Transwaste.
The plant near Hull in north England will produce biogas from municipal waste and inject up to 6mn m3 into the national gas grid each year. Its delivery is scheduled for December 2023.
Wartsila says its Puregas CA process recovers more than 99.9% of biomethane present in raw biogas by separating CO2 from biogas through chemical adsorption. According to the company, the technology has significant operational cost advantages, and is also able to handle biogas with high concentrations of volatile organic compounds without the need for costly pre-treatment.
“The operational cost advantages of Wartsila’s biogas upgrading solution are especially relevant now that energy costs are so high," the company said. "Our solutions are fully aligned with Wärtsilä’s strategy to develop and deliver solutions that support a sustainable future. Furthermore, this product will provide the customer with the lowest Total Cost of Ownership which is a key driver for both our product development and value propositions."
