Novatek patents LNG technology in six foreign jurisdictions
MOSCOW. May 27 (Interfax) - Novatek held patents to the natural gas liquefaction technology it developed in six foreign jurisdictions at the end of 2025, the Russian gas company said in its sustainability report.
Novatek did not specify in which jurisdictions the technology was patented.
Novatek head Leonid Mikhelson said earlier that the liquefied natural gas (LNG) technology the company has patented is only viable in the Arctic and that it would not make sense to use it even in the European part of Russia.
"At the end of the reporting year, the Company had a total of 38 valid patented inventions, over 78% of which were actively used in operations. Notably, 21% of all Novatek's inventions are related to enhancing LNG production efficiency. The rest of its developments are related to upgrading chemical engineering processes," the report said.
Novatek also said that "22 R&D projects aimed at bringing import-substituting equipment for LNG projects into production and operation" are being implemented under an agreement of intent signed with the Russian government to develop LNG production equipment in the period to 2030.
"A test bench for cryogenic dynamic equipment and the first stage of a test bench for integrated testing of high-capacity compressor units (using inert media) have already been commissioned," the report said.
Novatek registered three patents for its proprietary inventions in Russia in 2025. They address production challenges from drilling to geological modeling, the company said.
Novatek also confirmed in the report that it plans to be producing 57 million tonnes of LNG per year at its plants by 2030.
"The Company estimates that increasing total LNG deliveries from Novatek's projects to 57 million tons per year by 2030 could help avoid 95 million tonnes of CO2 eq. annually, assuming that customers switch from coal to LNG," the report said.
The company recalled that it holds the patent to large-scale production of low-carbon ammonia. Steam-oxygen reforming of natural gas produces synthesis gas, which is then scrubbed of CO2 and used to produce commercial ammonia. The use of this technology reduces the carbon footprint of the final product, Novatek said, adding that in 2025 it optimized technical solutions to ensure stable operation under various temperature conditions. Novatek said it also worked with equipment suppliers from Russia and friendly countries.
Novatek has patented its proprietary Arctic Cascade gas liquefaction technology with capacity of 0.9 million tonnes per year (a train was built at Yamal LNG), its Arctic Cascade Modified large-scale technology with trains of 3 million tonnes per year, and its Arctic Mix technology based on mixed refrigerants, which was developed for the company's large-scale projects involving gravity-based structures with trains capable of producing over 6 million tonnes of LNG per year.
