Transparency of carbon offsets Lenovo CO2Offset Services offer complete transparency throughout the process. At any time, you can download confirmation of your carbon offset and view details of the climate action project that your offset supports by adding the serial number of your device on theLen...
According to Zhejiang Energy, the project is designed to capture 15,000 tonnes of CO2 per year, equivalent to the total CO2 absorbed by 10 square kilometers of forest every year. During the running test, its average carbon capture rate reached 90 percent, with a capture purity of 99 percent...

Piperazine at 24 mol% of the total amine decreases CO2 equilibrium pressure by 50% and enhances the CO2 absorption rate by 50% to 100%. The CO2 enhancement factor decreases by a factor of 0.6 to 2 as loading decreases from 0 to 0.5 mol CO2/mole amine. 展开 关键词: Monoethanolamine ...

Fly ash is the by-product of coal combustion, which accounts for about 60%–88% of the total combustion residues in coal-fired power plants. About 0.75–1 billion tons of fly ash are produced every year globally [52]. However, the global average utilization rate is still below 30% [53...
Acquisition of CO2 by higher plants involves CO2 diffusion from the air into leaves and, ultimately, into chloroplasts. There, fixation of CO2 into organic compounds creates the concentration gradient which drives CO2 diffusion. CO2 encounters many obstr
Copper represents an effective catalyst in reducing CO2 to hydrocarbons or oxygenates, but it is often plagued by a low product selectivity and limited long-term stability. Here we report that copper nanowires with rich surface steps exhibit a remarkably high Faradaic efficiency for C2H4 that can ...
