A similar increase in capital costs in percentage terms is also typical for ultra-supercritical coal-fired TPPs, which have the highest efficiency among all solid fuel-fired power plants (44%–46% versus 37%–40% for supercritical power plants and 33%–37% for subcritical ones). The EIA estimates that the unit capital costs for ultra-supercritical coal-fired TPPs total $4,507 per kW of electricity, while the use of CCS systems with an efficiency of 30% and 90% raises the costs to $5,577 per kW and $7,176 per kW, respectively. This means that the capital costs of coal-fired TPPs are getting closer to the unit cost of construction of light water reactors ($7,406 per kW) and small nuclear power plants ($7,590 per kW).
CO2 capture & storage is a fast-growing segment of the global energy industry. BloombergNEF estimates that global investments in the construction of CCS systems almost doubled in 2023 (to $11.1 billion). The global capacity of operating CCS systems reached 52 million tons per year by the end of 2023, and hit 12 million tons and 134 million tons per year, respectively, for CCS systems under construction and design. The most popular method of CO2 capture remains the use of monoethanolamine, a colourless liquid with an ammonia odour that absorbs carbon dioxide very well. An alternative is the use of metal-organic frameworks (MOF) – lattice structures made of metal and organics that are capable of holding foreign substances and releasing them due to changes in temperature and pressure.
In addition to the power industry, CCS technologies could find the widest application in the cement and steel industries, where the production of industrial products is associated with high CO2 emissions (Scope 1 emissions), which cannot be offset by switching to low-carbon electricity sources (Scope 2) or adjusting the behaviour of end consumers (Scope 3).
