演讲主题：Understanding gas hydrates: Potential role towards net zero CO2 target
Hydrate are ice like crystalline solid which could form even at ambient conditions. While hydrates commonly forms in oil and gas pipelines leading to pipeline blockages, and are considered nuisance, hydrate research has however become popular due to its being an alternative resource of methane. As per recent estimates, total amount of carbon in methane hydrates, far exceeds the carbon content in all the fossil fuel reserves put together, and hence natural gas hydrates if exploited could be converted into blue hydrogen (through steam reforming). CO2 capture and sequestration are thus essential and would require a sustainable solution which is not only economical but also environmentally friendly. As of today, global CO2 emission is 36 billion tons of carbon dioxide every year which is increasing at an annual rate of 5%. The steep target of becoming net CO2 neutral by 2050-2060 is not feasible if we don’t create multiple mini- targets. One such target could be maintaining our CO2 emission to say 2020 level in next 10 years. If one has to achieve this target, roughly several billion tons of CO2 has to be captured and sequestered every year by 2030. This presentation would briefly explain hydrates at molecular level, and its potential application in achieving net zero carbon dioxide emission.
