Carbon-intensive industries must deem carbon capture, utilization, and storage initiatives to mitigate rising CO concentration by 2050. A 45% national reduction in CO emissions has been projected by government to realize net zero carbon in 2030. CO utilization is the prominent solution to curb not only CO but other greenhouse gases, such as methane, on a large scale.

The drawbacks are relatively large water swelling and lower OH conductivity at higher water uptakes, which are considered to be due to the entanglement of the flexible hydrophobic structure of the membrane.

In general, pure κ-carrageenan membranes show a low ionic conductivity. New membranes were developed by chemically modifying κ-carrageenan via phosphorylation to produce O-methylene phosphonic κ-carrageenan (OMPC), which showed enhanced membrane conductivity.
