SEMPRE-BIO – SEcuring doMestic PRoduction of cost-Effective BIOmethane

SEMPRE-BIO aims to demonstrate novel and cost-effective biomethane production solutions to support circular economy projects and reduce dependence on imports of natural gas and liquefied natural gas (LNG). Its goal is to promote the use of biomethane as a substitute for fossil fuels used in transportation and the natural gas grid, with an estimated reduction in CO2 emissions of 213 million tons per year by 2050.

With this in mind, SEMPRE-BIO will establish three European Biomethane Innovation Ecosystems (EBIEs) in Baix Llobregat (SP), Bourges (FR), and Adinkerke (BE) where five biomethane innovations technologies will be tested. The challenge is to lower investment and operating costs, optimize feedstock supply and use, identify alternative feedstock and reduce their costs, improve plant efficiency and operations, account for carbon savings, and increase and monetise benefits.

In Spain, the Baix Llobregat ecofactory will demonstrate biomethane production technologies that allow the valorisation of currently untapped biogas streams . The biogas will be converted into compressed natural gas (CNG) through a power-to-gas hydrogen methanation process, for use in Barcelona's public transport system. The Bourges green waste treatment plant in France will produce biomethane from non-digestible urban green waste for injection into the grid. Finally, in Adinkerke, Belgium, a farm with no connection to the natural gas grid and low biogas production, will demonstrate solutions for biogas purification and production of liquid biomethane, a renewable fuel ideal for heavy transport. The biomethane generated here will be stored locally in liquefied form and distributed by road transport, while the CO2 will be commercialized and its conversion to polymers and proteins will be studied.
