Gasification-based plants with coal-CO2 slurry feed are predicted to be more efficient than those with coal-water slurry feed. This is particularly true for high moisture, low rank coal such as lignite. Nevertheless, preparation of the CO2 slurry is challenging and the losses associated with ...

SYDNEY, Feb. 27 (Xinhua) -- Australian researchers have discovered a way to turn carbon dioxide (CO2) from the earth's atmosphere back into coal. Led by Australia's Royal Melbourne Institute of Technology (RMIT), the world's first breakthrough used liquid metals to convert the gas into so...
"While we can't literally turn back time, turning carbon dioxide back into coal and burying it back in the ground is a bit like rewinding the emissions clock," RMIT researcher Dr Torben Daeneke said. "To date, CO2 has only been converted into a solid at extremely high temperatures, makin...

The coal-fired power sector is facing unprecedented pressure due to the shift to low-carbon energy sources and the need to prevent climate change. It is imperative to incorporate advanced technologies into conventional coal-fired power plants to enhance
Deep coal-bearing formation (DCBF) has many advantages in geological CO2 storage such as large storage capacity as sedimentary formation and the CBM production by ECBMR from coal seam. A non-isothermal multi-phase multi-component fluid dynamic simulator for CO2 storage in DCBF was developed and...
ChemSusChem:原位构建COF-5/CoAl-LDH异质结用于可见光驱动CO2还原 武汉理工大学刘曰利教授课题组在ChemSusChem期刊发文,提出了一种原位构建1D/2DCOF-5/CoAl-LDH异质结的方法并应用于光催化CO2还原。该工作通过原位构建异质结,可协同耦合COF-5与CoAl-LDH材料的优势,实现良好的Vis响应、界面调控、电荷分离,为设计复合型...
However, Pahle stressed that now "we need effective political tools to ensure that the forthcoming implementation of the coal commission's decision actually reduces climate-damaging CO2 emissions." According to the analysis, the shutdown of coal-fired power plants in Germany would decrease the supply...
