Cost of capturing CO2 using membranes?
…means 0.1 m2 of membranes are needed per m3 of feed gas per hour. Low pressure separation is also important, as compression energy costs comprise around a 13% energy penalty…
Helion: linear fusion breakthrough?
…to confining magnetic field energy. Helion’s patents cover a field reversed configuration of magnets which will “have the highest betas of any plasma confining system”. During compression, different field coils…
Renewables: can oil and gas assets “demand shift”?
…find. Across CO2-compression and lifting operations, we estimate there could be as much as 35kWh of electricity used per barrel of oil production. CO2 injection does not need to take…
Ethane cracking: the economics?
…intensity of ethylene production? Gas use (in mcf/ton) and electricity use (in kWh/ton) are captured in the model, and built up across pyrolysis, compression and separation. At $3/mcf gas and…
The future of offshore: fully subsea?
…(primarily Equinor, but also TOTAL, Shell). The leaders in subsea compression technology are assessed on pages 16-17. The leaders in subsea power systems are described on pages 18-19. The leaders…
CO2 intensity of shale: breakdown by category?
…and personnel, lifting, flaring, methane leaks, gas gathering and compression for gas transport. Our base case estimate is that the Scope 1&2 CO2 intensity of shale oil is around 25…
Subsea Separation: the elusive history
…about the data is how elusive the technology’s ascent has been. Two of our projects were cancelled. The largest were 2.3MW. Subsea Boosting and Compression has been 4x more prevalent…
De-Carbonising Cars. Can Oxy-Combustion Save Gasoline?
…on board the mobile vehicle will be necessary, until it can be discharged at a disposal facility. This requires compression energy, to pressure the CO2 to 5-1,600kg/m3. There may be…
Oxycombustion: economics of zero-carbon gas?
…super-critical CO2 compression. Our model of oxycombustion costs, averaging 6-8c/kWh in our base case, is based on assumptions for capex, opex, utilization, efficiency, gas prices, oxygen costs and CO2 disposal….
