The first public station in Spain capable of supplying bioLNG and biomethane for all types of vehicles is now operational in Zaragoza . Located at the El Cisne service area, at kilometer 309 of the A-2 highway, the facility is poised to become a benchmark for both professional and private transport seeking cleaner alternatives to fossil fuels.
The project is the result of a collaboration between Redexis, Zoilo RÃos, and Axpo , who have combined their expertise in infrastructure, service station operation, and renewable gas marketing. Thanks to this agreement, the station offers COâ‚‚-neutral renewable fuels and aligns with the decarbonization and energy transition strategies that are gaining traction in the Spanish transport sector.
A pioneering project in the renewable refueling network
The new facility has been designed as a publicly accessible biogas station that allows refueling with both bioLNG and biomethane at the same location. BioLNG is primarily intended for long-haul trucks and heavy vehicles , while biomethane is for passenger cars, vans, and fleets that use gas as fuel.
According to the companies involved, the El Cisne station is considered a pioneering project within the Spanish alternative fuels network , as it is the first to combine these two renewable gases in facilities open to the public. This configuration allows both freight and passenger transport to access a stable renewable refueling point , with prices lower than those of conventional fossil fuels.
The new biogas station is integrated into the Redexis mobility network, which already has more than 40 natural gas vehicle refueling stations in Spain and is working on the development of biomethane and green hydrogen projects. In this context, the Zaragoza station acts as a key link in expanding the use of renewable gases along the country's main transport corridors.
For its part, Axpo supplies the renewable gas with guarantees of origin that is dispensed at the pumps. The company, which presents itself as the largest biomethane marketer in Spain, sees this collaboration as another piece of its growth plan in the national market, where it expects to reach around one terawatt-hour of biomethane projects by 2030.
Zoilo RÃos, responsible for managing the service station, integrates this biogas plant into a broader strategy of sustainable mobility and energy diversification , which already includes other solutions such as vehicular natural gas, renewable hydrogen or alternative fuels for pilot tests of new transport technologies.
El Cisne, a strategic point on the A-2 and next to PLAZA
The chosen location is no coincidence. The station is situated at the El Cisne service station, on the left side of the A-2 highway, kilometer 309 , at the entrance to the Zaragoza Logistics Platform (PLAZA), considered one of the largest logistics centers in Europe. This area handles a significant portion of road freight traffic on the Iberian Peninsula.
Data from the development companies indicates that over 6.000 heavy goods vehicles travel this section of the highway daily . Zaragoza also serves as a connecting hub between Madrid, Barcelona, ​​Bilbao, and Valencia , and as a natural passage for international routes to France, making the station a particularly attractive location for both national and international fleets.
Located next to one of Europe's largest logistics hubs, the biogas plant strengthens the alternative energy supply for transport companies and logistics operators working in PLAZA and nearby corridors. This makes it easier for large fleets to gradually incorporate vehicles powered by bioLNG or biomethane without having to deviate from their usual routes.
The station is also open to light vehicles and private cars , so people traveling on the A-2 or moving around Zaragoza can opt for renewable fuel if they have gas-powered vehicles. In this way, the project's impact extends beyond professional transport to encompass everyday mobility.
This strategic location makes the facility a possible replicable model in other logistics hubs in Spain and Europe , where the transit of goods is intense and the potential demand for renewable fuels is beginning to grow in line with decarbonization policies.
BioLNG and biomethane: how and for whom they are supplied
The station is equipped with dedicated bioLNG pumps that serve long-haul trucks and heavy vehicles. Because this fuel is liquefied, it allows for greater energy storage in the tank, which is especially useful for long routes requiring extended range and minimal downtime.
Alongside bioLNG, the facility has biomethane gas dispensers for cars, vans, and trucks that use compressed gas. Biomethane has similar characteristics to natural gas but with the advantage of being derived from renewable sources, such as organic waste , which helps to close the material cycle and move towards a circular economy.
Project leaders emphasize that refueling times are comparable to those of traditional fuels : around three minutes for cars and light vehicles, and up to eight minutes for trucks and heavy vehicles. This speed is a key factor in making these alternatives viable for the professional transport sector, as it does not require drastic changes to daily operations.
As it is a public station, access is not limited to large operators. Any user with a gas-powered vehicle can refuel with biomethane or bioLNG under the usual conditions of a conventional gas station , with the added benefit that the fuel supplied is renewable and COâ‚‚-neutral throughout its life cycle.
Combining both products in the same location makes it easier for different types of fleets to share infrastructure , from long-distance trucks to urban delivery services or private vehicles, thus optimizing the use of space and the investment made.
Environmental impact and contribution to the circular economy
One of the key points emphasized by Redexis, Zoilo RÃos, and Axpo is the station's potential to reduce carbon dioxide emissions . The companies estimate that using bioLNG and biomethane at this facility could prevent more than 2.000 tons of COâ‚‚ emissions per year compared to equivalent fossil fuels.
This reduction in emissions is due to the fact that both fuels are renewable and considered COâ‚‚ neutral in their overall balance , since the carbon they release during use comes from biomass and does not add additional fossil COâ‚‚ to the atmosphere. Furthermore, they are usually produced from organic agricultural, livestock, urban, or industrial waste , which allows for the valorization of waste streams that could otherwise generate uncontrolled emissions.
In this sense, the project aligns with the principles of the circular economy : waste that was previously an environmental problem is captured and treated, transformed into biogas, and, after purification, converted into biomethane suitable for vehicle use. BioLNG is essentially this liquefied biomethane for use in long-haul trucks.
In addition to the direct environmental benefits, the station contributes to strengthening Spain's energy independence by utilizing local resources and reducing the need to import fossil fuels. This diversification of energy sources is seen as an important element for improving security of supply in a context of energy transition and international price volatility.
The companies involved also point out that projects of this type help to consolidate a renewable gas value chain in the country , from biomethane production plants to distribution networks and end-use points, generating economic activity and investment opportunities in different territories.
The companies behind the Zaragoza biogas plant
Redexis ' role in the project focuses on the development and operation of the energy infrastructure needed to supply bioLNG and biomethane. The company, which specializes in the transport and distribution of natural gas and LPG, has been expanding its activities in recent years into renewable gases and sustainable mobility solutions , with significant investments since 2010 and a network of natural gas vehicle refueling stations already deployed throughout the country.
The Zoilo RÃos Group , with nearly a century of history in Aragon, manages the El Cisne service station. The company, which operates a network of service stations and has been incorporating natural gas, biofuels, and other energy alternatives for years, has transformed this location into a small hub of innovation in mobility. Here, hybrid trucks powered by hydrogen and renewable diesel have been tested, and a hydrogen refueling station has been installed for the region's first regular renewable hydrogen bus line .
Axpo , for its part, supplies the renewable gas sold at this station. The energy company, with an international presence and a broad client base in Europe, North America, and Asia, has been active in the Spanish market for some time, where it claims to be one of the leading players in the biomethane market . Its participation guarantees the supply of renewable gas with traceability and sustainability criteria.
The alliance of these three companies allows for the combination of infrastructure, operational experience and renewable gas supply capacity , a set of factors that is key for the station to offer continuous and reliable service to businesses and individuals.
This collaboration also fits with the corporate strategies of the three entities, which have placed the decarbonization of transport and the energy transition as central pillars of their growth and innovation plans in the coming years.
A model with the potential to expand to other corridors
The opening of this station in Zaragoza places Aragon on the national map of renewable mobility initiatives linked to the use of biogas. The project is presented as a benchmark for future similar developments at other points on the Spanish road network and, potentially, across Europe.
The promoting companies emphasize that the El Cisne biogas station offers a value proposition that can be replicated in other logistics hubs : integrating the supply of bioLNG and biomethane in a single location, facilitating access to renewable fuels for fleets of different sizes, and maintaining refueling times and operations very similar to those of a conventional station.
Looking ahead, infrastructure like this could encourage more transport companies to renew part of their fleets with renewable gas vehicles , especially in corridors where a sufficient number of refueling points are being established. This aligns with European targets for reducing emissions in road transport.
For private users with gas-powered vehicles, having a station of this type on a road as heavily used as the A-2 means having an additional option to travel with renewable fuels between the main cities of the country, without depending solely on conventional natural gas stations.
With this initiative, Zaragoza reinforces its role as a real laboratory for energy solutions applied to transport , adding the bioLNG and biomethane biogas plant to other renewable hydrogen, vehicular natural gas and low-carbon alternative projects already operating in the area.
The opening of Spain's first public bioLNG and biomethane refueling station, located in El Cisne (Zaragoza), brings together technological innovation, a strategic location, and a supply of renewable fuels for all types of vehicles. With its capacity to reduce thousands of tons of COâ‚‚, its role in the circular economy, and its integration into the national logistics network, this biogas station represents a significant step in the transformation of road transport towards more sustainable and diversified energy models.
