Norwegian petroleum refining firm Equinor said on Monday it signed a 15-year agreement with the Indian fertiliser and petrochemical company Deepak Fertilisers for supplies of liquefied natural gas with deliveries starting in 2026. The agreement covers an annual supply of around 0.65 million tons of LNG. The ammonia which Deepak will produce from the natural gas will be for domestic use in India. Ammonia is a base material for fertilizer and therefore often plays a crucial role in agricultural productivity.
