Gas Natural Fenosa works together with the Hera Group in a project to convert biogas into biomethane. This project is already in the second phase, in the municipality of Arazuri (Navarra). Up to now, renewable gas was used directly to generate electricity through engines, but work is currently being done to adapt this gas to be equivalent to natural gas, eliminating part of the carbon dioxide and other impurities in the biogas.

The project that is a pioneer in Spain began with a first phase in the municipality of Góngora (Navarra). In it, the companies analyzed whether gas from organic waste from the municipal landfill could be used to generate fuel for vehicles. The result was that the gas quality was not enough and phase two began in the municipality of Arazuri (Navarra). For the time being, the biogas that comes from the wastewater station of Arazuri, once treated, is used in three vehicles of the fleet of the Commonwealth of Pamplona, an urban transport bus and two gardening waste collection trucks. It is an initiative that has the support of the company NILSA (dependent on the Government of Navarra), the public company SODENA, FCC and TCC companies, and the Commonwealth of the Pamplona Region.

At this moment, the project is in the second of three phases, demonstrating that biogas is suitable for the production of biomethane with an acceptable quality for vehicular use, and to inject into the network. The next stage will seek the improvement of the gas to inject it into the distribution network of natural gas, validating the technology, knowing costs and optimizing them.
