Oxy-combustion: economics of zero-carbon gas?

Oxy-combustion is a next-generation power technology, burning fossil fuels in an inert atmosphere of CO2 and oxygen. It is easy to sequester CO2 from its exhaust gases, helping heat and power to decarbonise. The mechanics are described here. We model that IRRs can compete with conventional gas-fired power plants.


This is our model of the economics. It is constructed from technical disclosures. For example, Occidental petroleum and McDermott have already invested in one of the technology-leaders, NET Power, which constructed a demonstration plant in LaPorte Texas, starting up in 2018.

A review of recent project progress has also been added to the data-file in early-2020.  Details remain relatively secretive. But we find 9 potential deployments which are being moved towards commerciality. The details we have found are summarized in the data-file.

Long-Term LNG Demand: technology-led?

This is a simple model of long-term LNG demand, extrapolating out sensible estimates in the world’s leading LNG-consuming regions. On top of this, we overlay the upside from two nascent technology areas, which could add 200MTpa of potential upside to the market. Backup workings are included.

De-carbonising carbon?

Decarbonisation is often taken to mean the end of fossil fuels. But it could become more feasible simply to de-carbonise fossil fuels. This 19-page note explores two top opportunities: next-generation combustion technologies, which can meet the world’s energy needs relatively seamlessly, with zero carbon and little incremental cost. They are ‘Oxy-Combustion’ using the Allam Cycle and Chemical Looping Combustion. Leading Oil Majors support these solutions to create value advancing the energy transition.
