Review of the operational flexibility and emissions of gas

At full load, specific emission factors for all pollutants are found in most cases higher in coal-fired power plants than in gas-fired power plants On average, NOx, CO and CO 2 emissions are 50–100% higher in coal plants than in natural gas plantsPower Plant Cycling Cost and Flexible Generation,Our team has studied over 500 power plants, including gas, oil, and coal-fired steam units, combustion turbines/combined cycle; nuclear; hydro; compressed air energy storage, and pumped storage in addition to fleet wide studies in North and South America, Australia, and EuropeCycling Coal to Balance Electricity Grids | Energy Matters,In response, production from coal plants has been successfully turned down to just 20-60 percent of normal output The advisory board claims part-loaded coal-fired plants have been able to ramp down by as much as 3 percentage points per minute The board’s optimism is spoiled, however, by the financial woes of Germany’s big coal-fired generators RWE this month announced yet more job cuts and said
