MHI CCS technology: performance, costs and emissions?
…lower than MEA, especially when CO2 capture plants are fitted with all the usual bells and whistles to remove particulates, NOx and SO2 from exhaust gases upstream of the CO2…
Energy transition: investment strategies?
…industry to iron out ammonia engines, despite challenging combustion properties, prevent NOx emissions, and retrofit existing bulk carriers and container ships, which clearly does carry new market risk. Another interesting…
Dreaming of Electric Frac Fleets?
…gas prices. Additional benefits are also noted in the file, such as CO2 reductions, higher reliability, smaller pad sizes, NOX reductions and noise reductions. We also think over the long…
Membrane Technology and Research: CCS breakthrough?
…90%. There was minimal impact on CO, SO2 or NOx formation. In 2021-22, MTR’s Gen-2 Polaris membrane-frame modules were also tested at Technology Centre, Mongstad (TCM), for 2,200 hours, using…
CCS challenges: by any amines necessary?
…gases (SOx, NOx, particulates, etc, data here). It is important to quantify and to understand these various CCS challenges, in order to risk CCS deployments appropriately. Or, conversely, to de-risk…
Flue gas desulfurization: costs of SO2 scrubbers?
…of coal power. Levelized cost debates. One of our ongoing reasons for disliking levelized cost analysis is that comparisons are often not apples to apples. To reduce the SOx, NOx…
Gas turbines: operating parameters?
…to 70% below coal power plants). NOx emissions are usually below 25ppm but can be as low as 2ppm in the best models. Many new turbines are also hydrogen-ready, and…
Cable installation vessels: costs and operating parameters?
…will be able to lay two cables at once. Generally these cutting edge vessels also boast improved environmental performance, with less CO2, NOx, hybridization or readiness to run on biofuels….
How does methane increase global temperature?
…with oxygen atoms in NOx pollutants, yielding O3. And thus methane is assumed to increase tropospheric ozone. Several authors, including the IPCC, have proposed to scale up alpha values by…
Costs of CCS with the amine process?
…such as dust removal via ESPs, sulfur removal via scrubbers, or NOx removal via SCRs, all of which may be necessary to prevent dangerous amine degradation and emissions. This note…
