The following emissions levels were calculated: eCO2 = 396 g/kWh; eH2S = 1.21 g/kWh; eHg = 1.3 g/kWh; these figures correspond to measurements taken by the pollution control authority. It should be underlined that the CO2 emissions are of natural origin; however, they are of similar ...
Using a CO gas feed, we demonstrate an energy efficiency of ~40% with a C2H4 Faradaic efficiency of 86 ± 2%, corresponding to a low electrical power consumption of 25.6 kWh Nm−3 for the CO to C2H4 conversion reaction. Our findings provide a route towards practical ...
As natural gas emits less than 50% of the CO2 per kwh that coal does, emissions might have dropped as a result of fuel competition. Policy-wise, greenhouse gas emissions from the generating fleet have become a nationwide concern: in 2013, U.S. electricity generation accounted for more than...

on a mole basis. Our calculations indicate that even an ideal catalytic process needs to be powered by electricity emitting less than 0.2 kg of CO2per kWh to achieve a net reduction in CO2. We conclude that hybrid processes combining thermocatalysis and electrocatalysis are promising opportunities ...

battery pack's charge level as well as the car's current energy usage. At the top between the round gauges there is a display where the driver can scroll between average consumption in kWh/100 km, current consumption in kWh/100 km, remaining range at current driving style and average ...
This derives from an increasing heliostat field size per tower, including a (marginally) reduced field efficiency. Case 3: high DNI In the third case, the influence of higher DNI (data set P50; 2207 kWh/m2a) is investigated. All other assumptions remain the same compared to the base ...
We used an average of 0.30 kWh/kgLNG and applied the same method and economic parameters as for amine-based DAC. The levelised cost of methane liquefaction was estimated to be $2.8/GJ, which would increase the overall cost for large-scale LSM production (~360kt/a LSM) to ~$31.5/GJ. ...
