Greenfield LNG: Does Exxon have an edge?

For large-scale capital projects in a commodity industry, harnessing better technologies tends to unlock better returns.

Hence this 7-page note evaluates ExxonMobil’s technology for constructing greenfield LNG plants, particularly in remote geographies. Its technical leadership stands out from our analysis of 3,000 patents across the industry. This matters as Exxon progresses new LNG investments in Mozambique, PNG and the US.

ExxonMobil has leading LNG technology for extra-large trains using the APX process, modular LNG units that minimise on-site construction costs, pressure-swing absorption to remove gas-contaminants and efficient gas turbines.

Opportunities should arise for investors in Exxon’s LNG projects, and for its partners, resource-owners and other stakeholders, to ensure that value is maximised.

The World’s Great Gas Fields and Their CO2

The CO2 content of gas fields is going to matter increasingly, for future gas development decisions: CO2 must be lowered to 50ppm before gas can be liquefied, adding cost. Moreover, it is no longer acceptable to vent the separated CO2 into the atmosphere.

Large, low-CO2 resources like the Permian, Marcellus and Mozambique are well-positioned to dominate future LNG growth.

This data-file tabulates 30 major gas resources around the world, their volumes, their CO2 content and how the CO2 is handled.

LNG Process Technologies — an Overview

This file will give a helpful overview of the different process technologies, which are used in LNG liquefaction: APCI, APX (Exxon), Optimised Cascade (Conoco), Fluid Cascade (Equinor), DMR, SMR, PRICO (Golar) and MMLS (Shell, small-scale). For each one, we summarise how it works, advantages and disadvantages, plus typical train sizes, energy efficiencies, examples and involved-companies. We also touch on applicability for FLNG and small-scale LNG.
