China Huaneng Group placed its 1.5 Mtpa post-combustion carbon capture project into operation on Sept. 25, 2025, following a 72-hour trial run at the Zhengning coal-fired power plant (2 × 1,000 MW) in Gansu Province. Integrated into the Huaneng Longdong Energy Base, the facility reportedly captured more than 90% of CO2 from desulfurized flue gas using Huaneng’s proprietary HNC-7 solvent system, with captured CO2 designated for geological storage and utilization, according to the Global CCS Institute.

    EPA Proposes Tighter NOx Limits for Combustion Turbines

    The U.S. Environmental Protection Agency has proposed tougher nitrogen oxide (NOx) emissions limits for new, modified, and reconstructed stationary combustion turbines. The proposed rule identifies a combination of combustion controls and selective catalytic reduction (SCR) as the Best System of Emission Reduction (BSER) for most turbines though it proposes combustion controls alone for certain smaller […]
