editHello, Minhtrang 92, and welcome to Wikipedia! My name is Ian and I work with the Wiki Education Foundation; I help support students who are editing as part of a class assignment.
I hope you enjoy editing here. If you haven't already done so, please check out the student training library, which introduces you to editing and Wikipedia's core principles. You may also want to check out the Teahouse, a community of Wikipedia editors dedicated to helping new users. Below are some resources to help you get started editing.

Our group topic is Calcium Looping. Some ideas that we will be focus on: Technical Implication Economic Implications Environmental/Political Implications Feasibility of Technology
The biggest thing we have to contribute to the current Wikipedia entry on Calcium Looping is specificity to carbon capture and storage. While the entry does contain a section titled “Benefits of CaL compared with other post-combustion capture processes”, it is empty. We have several resources specifically describing the efficacy of Calcium Looping in relation to capture methods like solid sorbent capture and membrane scrubbers present in the bibliography. The entry offers a very basic technical explanation of the process which we will make more specific and comprehensive. While it does explain the basic technology, it fails to cover the political implications; something that is necessary to understand in order to evaluate the true viability of the process. It is politically divisive, seen as financially extravagant and an unnecessary expense. While the entry describes in brief the process of calcium looping, it does not describe how the process would be implemented; nor does it describe in depth the drawbacks to calcium looping as a process. While calcium looping is a viable carbon capture strategy, some resources we have compiled raise caveats to its efficacy, notably the high amounts of waste solvent that make the process expensive to run for extended periods of time. Providing the conflicting viewpoints presented in these sources would make the entry more comprehensive and less opinionated. In order to surmount these obstacles, technological advances in decreasing the waste product would have to be made; advances which are described in portions of our bibliography, but not at all in the entry. Finally, the entry is poorly referenced. Similar carbon capture articles contain an excess of 100 references, whereas the calcium looping entry only contains 16. Just in preliminary research we have amassed a bibliography of 21 sources, dwarfing the number of the current entry. Overall, there is a great deal we can add to the current Wikipedia entry on Calcium looping, and we are looking forward to getting started.
