Fossil fuels can be used with minimal atmospheric emissions of carbon dioxide by capturing and storing the CO2 away in geologic structures. However, stored CO2 can leak back to the atmosphere reducing the utility of this technology. To explore the trade-offs between discounting, leakage, the cost of sequestration and the energy penalty (the energy necessary to capture, transport and inject carb...

The goal of carbon sequestration is to take CO2 that would otherwise accumulate in the atmosphere and put it in safe and permanent storage. Most proposed methods would capture CO2 from concentrated sources like power plants. Indeed, on-site capture is the most sensible approach for large sources and initially offers the most cost-effective avenue to sequestration. For distributed, mobile source...

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 ...

this study investigated different concepts for natural-gas-fired power plants with the co2capture, and compared them based on the net plant efficiency and emission of co2. the cycles were based ona six oxy-fuel, one post-combustion and two pre-combustion capture concept. this paper presented theresults of an environmental evaluation performed by the application of the life cycle analysis (lca) ...

One of the most relevant European R&D&d initiatives focusing on Carbon Capture Utilization and Storage (CCUS) is the CIUDEN Carbon Capture and Storage Integral project, supported by the Spanish Government through the Foundation Ciudad de la Energia (CIUDEN). CIUDEN is a public institution created by the Spanish Administration in 2006 and fully conceived for collaborative research, development a...

Clean energy sources and global warming are among the major challenges of the 21st century. One of the possible actions toward finding alternative energy sources and reducing global warming are storage of H2 and CH4, and capture of CO2 by using highly efficient and low-cost adsorbents. Graphene and graphene-based materials attracted a great attention around the world because of their potential ...
