Summary

The Andasol Solar Power Station in Andalucía, Spain uses molten salt as a thermal storage material to generate renewable solar-thermal energy.

The biggest obstacle in large-scale implementation of CCS technology is cost, as many absorption, adsorption, and membrane technologies are either too costly or impractical. Costs arise through parasitic energy (ranging from 15-30% of the total energy produced by the plant), as well as through expenditures on transportation and infrastructure. Ionic liquids have potential applications in carbon capture and sequestration as absorbents. Thus, through this project, we are investigating the use of ionic liquids in the carbon capture process, as it demonstrates promising results in reversible capture. Ionic liquids have many desirable properties that can potentially be the catalyst to realizing CCS technology. In the article we are editing, we plan to delineate the benefits of ionic liquids, and how they are the result of its properties. Then, we plan to discuss future work to expand its capability specifically related to carbon capture. Finally, we will investigate the economic aspect of using ionic liquids on an industrial scale, and hope to include sample calculations.

Ionic liquids are simply the liquid state of ionic solids. Molten salts are ionic liquids. Most ionic solids have very high melting points: for example, table salt (NaCl) melts at 810°C. Though ionic liquids have been studied for over a century, recently, within the past 20 years, research interest has grown in their potential applications. Besides separations, ionic liquids can be used in molten salt nuclear reactors, batteries, and thermal storage, such as that used in solar-thermal power plants. The urgency of climate change has spurred research into these energy-related applications. One of the main drawbacks of ionic liquids is their high viscosity, which complicates their use in industrial operations. Supported ionic liquid phases (SILPs) are one proposed solution to this problem. Ionic liquids are versatile and tunable, making them an interesting area of research into novel materials.

Articles to improve/add sections to

• Carbon capture and storage - doesn't mention ionic liquids at all, could add section on it. Also doesn't have any information on parasitic energy, and the information on costs (which is the main area that needs to be improved) is very scattered and could be organized better.
• Carbon dioxide scrubber - has other absorption techniques but not this one
• Ionic liquid especially under Applications

Potential articles

• /Ionic liquids in carbon capture and sequestration
• Research in ionic liquid
• Thermodynamic properties of ionic liquids
• Tunable solvent (there are a couple other articles on other tunable materials, including tunable metamaterials and tunable nanoporous carbon)
