As one of Chile’s main economic activities, aquaculture faces the challenge of reducing its environmental footprint. Lipigas has been a strategic partner in this transition, developing solutions based on liquefied petroleum gas (LPG) and liquefied natural gas (LNG) for the generation of steam and hot water with maximum efficiency. Currently, some of the country’s main salmon companies operate with the Lipigas Personalized Industrial Plan (PPI), a model designed to adapt to the specific needs of each client. This plan offers expert advice, continuous monitoring and a competitive alternative to replace more polluting fuels such as diesel and fuel oil 6 (f06) with gas. It also optimizes energy consumption, reducing base energy by between 5% and 15%, and contributes to the industry’s sustainability objectives by reducing CO₂ emissions by between 18% and 30%, and reducing particulate matter by more than 90%. International green corridor In November 2024 Lipigas signed an alliance with AquaChile and Transportes GLA to create the salmon industry’s first fleet of LNG trucks. This agreement allows a 90% reduction in particulate matter emissions, a 20% reduction in CO2 emissions and a 50% reduction in noise pollution in long-distance transport to move products between fish farms and production plants. The initiative materialized at the beginning of February when the first transfer of fresh salmon in an LNG truck was made on the Puerto Montt-Santiago route. Lipigas’ LNG, Biofuels and Green Hydrogen assistant manager, Nicolás Hidalgo, pointed out that: “At Lipigas we are committed to liquefied natural gas (LNG) and BioLNG as accessible, efficient and sustainable alternatives for cargo transportation. With a range of 1,600 km and refueling times of only 10 minutes, we are setting a milestone in the transportation industry. In addition, we continue to advance in the creation of a green corridor of LNG and BioLNG refueling stations, linking Lima and Puerto Montt, driving cleaner logistics for Chile and the region.” Currently, the Lipigas green corridor has stations in Chile (Tabolango, Paine, Linares, Puerto Montt) and Peru (Lima, Nazca, Arequipa), with upcoming expansion to Calama-Baquedano in the Antofagasta Region. In addition, LPG and LNG are being used in boilers for steam generation, condensing boilers that heat water in fish farms, the conversion of outboard engines (LPG only), and the replacement of diesel generators for electricity generation. Upcoming projects Lipigas is working on another series of solutions that seek to provide access to renewable energies, which can be used in the aquaculture industry. For example, the first renewable liquefied natural gas (LNG-R) plant in South America, located in the Ñuble Region, will start operating in the first half of this year. This project will develop solutions for its end customers with a fuel that is carbon neutral and uses the same infrastructure as the existing LNG. In addition, the company closed a strategic agreement with ENAP to develop renewable liquefied gas (BioGLP) and renewable diesel in Chile, strengthening the transition to cleaner energies. As part of this initiative, Lipigas will have the first renewable liquefied gas molecules available in the first quarter of 2025. Both BioGNL and BioGLP fulfill the same function as their conventional versions, but with a renewable origin, significantly reducing the carbon footprint and contributing to the decarbonization of the energy sector. With these initiatives, Lipigas will be present at the second edition of AQUASUR TECH 2025, reaffirming its role as a key player in the energy transition of Chilean aquaculture.
