Cycling coal and natural gas-fired power plants with CCS
نویسندگان
چکیده
The profitability impacts of solvent storage are modeled for new coal and natural gas-fired power plants with amine and ammonia-based post-combustion CCS facing variable electricity prices. With perfect information of future prices, up to 3 hours of solvent storage was valuable due to price volatility at carbon prices up to $40/tonne CO2 and no regenerator undersize. With imperfect information with relaxed constraints on regenerator undersizing, up to 8 hours of solvent storage was valuable when coupled with an undersized CO2 capture system at carbon prices up to $60/tonne CO2. The results indicate that storage does not have value above the breakeven CO2 price for these plants. © 2013 The Authors. Published by Elsevier Ltd.

High Efficiency Electric Power Generation; The Environmental Role
Electric power generation system development is reviewed with special attention to plant efficiency. While higher efficiency is well understood to be economically beneficial because of fuel savings, its effect upon reduction of all plant emissions without installation of additional environmental equipment, is less well appreciated. As CO2 emission control is gaining increasing acceptance,effici...
متن کاملTwo scenarios for carbon capture and storage in Vietnam
Vietnam plans to develop dozens of new coal-fired power generation units over the next 20 years. In order to reduce emissions, it may appear necessary to dispose of these plants' CO2 by burying it in deep underground geological formations instead of releasing it into the atmosphere, using Carbon Capture and Storage (CCS) technology. We show that CCS has a technical potential in Vietnam. To disc...
متن کاملWater use at pulverized coal power plants with postcombustion carbon capture and storage.
Coal-fired power plants account for nearly 50% of U.S. electricity supply and about a third of U.S. emissions of CO(2), the major greenhouse gas (GHG) associated with global climate change. Thermal power plants also account for 39% of all freshwater withdrawals in the U.S. To reduce GHG emissions from coal-fired plants, postcombustion carbon capture and storage (CCS) systems are receiving consi...
متن کاملCarbon charges and natural gas use in China
Substitution of natural gas for coal in China’s power sector could significantly reduce emissions of carbon dioxide, but gas-fired power is generally more costly than coal-fired power in China today. This paper explores how carbon charges and carbon sequestration technology might tip the balance in favour of gas. The costs of electricity from new coal-fired and gas-fired power plants in China a...
متن کاملDivision of Economics and Business Working Paper Series A one-two punch: Joint effects of natural gas abundance and renewables on coal-fired power plants
Since 2007, coal-fired electricity generation in the US has declined by a stunning 25%. At the same time, natural gas-fired generation and wind generation have dramatically increased due to technological advances and policy interventions. We examine the joint impact of natural gas prices and wind generation on coal generation, with a particular focus on the interaction between low natural gas p...
