Novel Materials for CO2 Separation

Dear Colleagues,

The requirement of more energy-efficient water treatment and CO₂ capture and conversion technologies are major global challenges, since the estimated cost of the abrupt sea level rise ranges from $200 to $800 trillion over the next 30 years, and the estimated cost of CO₂ capture and storage at $40/ton of CO₂ captured is on the order of $16 trillion. Βased on this, if the aforementioned cost of the sorption CO₂ capture technologies will be reduced down to $20/ton of captured CO₂, the estimated savings will range from  $192 to $792 trillion.

One of the most promising approaches to achieving the aforementioned required cost reduction of the CO₂ is the development of “next-generation” sorbent and membrane materials and their effective deployment in novel design sorption and membrane intensified processes in order to drastically reduce the CO₂ capture cost by $8 trillion. Equally important is the  challenge of converting the captured CO₂ to high-added-value chemicals.

Regarding the challenge of the global warming, it is estimated that a total cumulative mass of approximately 100 Giga-tonnes CO₂ will need to be captured and stored or converted cost-effectively between 2030 and 2050. One major need is the reduction in the required energy capture down to 1.5 GJ/ton CO₂ captured. To this end, the development of “next-generation” low-cost, high CO₂ sorption capacity, and high CO₂ diffusivity sorbents as well as low-cost, high CO₂ flux membranes and their deployment in novel sorption, membrane, and hybrid sorption/membrane processes is necessary.

In addition, regarding the disposal of the captured CO₂, the development of cost-effective conversion processes for captured CO₂ based on novel catalysts, high flux separation, and catalysis can provide the required low-energy conversion of the captured CO₂ to fuels and chemicals.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.
