This article makes a strong case for the establishment of a Ministry of Gas Development and Industrialisation by the President Bola Ahmed Tinubu-led Federal Government of Nigeria. This is in order for Nigeria to harness to the fullest the 35 years window of opportunity Nigeria’s 2060 net zero emission target presents for the maximum development of its gas resources for power generation, industrialisation and household utilisation. The article is a follow-up on the previous two articles titled, “Upping the ante of Nigeria’s gas ambition” (part 1) and (part 2), which reviewed the impressive progress made in the last 30 months in the implementation of the Decade of Gas initiative, particularly the completion/near completion of three major gas pipeline projects and the imminent completion of the NLNG Train 7 in the first quarter of 2026 and subsequent commissioning later in the year. The articles recommended a radically revised and upgraded 10-year gas development plan terminating in 2035 targeting the production of 20 billion cubic feet/day (bcf/d) as against 7.5 bcf/d) in 2025.
