W.r.t. the FCCHP, it generally operates at the second operational regime with high electrical efficiency when the electricity price is high.
This observation illustrates that the CNT/Au/TiO2 nanocomposites modified electrode could obviously increase the relevant electron transfer rate and promote the electron exchange at electrode surface, which could readily provide enhanced stability and relatively long life-span to facilitate the high electricity production efficiency, suggesting its promising prospect application in MFCs.
Among the systems producing only electricity with CO2 capture, the CLC based process achieves the highest electrical efficiency (38.7%) compared with PSA (37.4%) and Selexol (36.4%) based processes.
It is characterized by its high coal-electricity efficiency, zero net CO2 emission and no pollutants.
A novel thermodynamics cycle power generation system based on coal gasification in supercritical water was proposed with the obvious advantages of high coal-electricity efficiency and zero pollutant emission.
In other words, the results suggest that electricity efficiency is higher in Kanagawa, Saitama, Chiba, and Tokyo owing to the floor area.
A few WWTPs operating in developed countries (USA and Germany) have already achieved almost 100% (or higher) electricity self-sufficiency through energy efficiency and harvesting biogas and electricity.
HTRs were initially designed for high temperature, high efficiency electricity generation but the technology, the market and the targeted applications have evolved since then to address industrial cogeneration and new operational conditions (in particular new safety regulations).
The base case has a higher net electrical efficiency of 41.4% compared to the other cases (cases 1, 2, and 5), which produce only electricity with CO2 capture.
A DSSC comprising the hybrid CE with a weight ratio of PtNPs to VGCFs of 3 7 (PV37) illustrated a higher solar-to-electricity efficiency of 7.77% in comparison to 7.31% for a conventional Pt CE or 3.79% for a pure VGCF CE.
