Biogas as a renewable energy resource can be broadly recognised carbon–neutral fuel which reduces anthropogenic greenhouse gas emissions, mitigates global warming, and diversifies supply. However, the biogas share in supply chain technology deployment maturity are not commensurate with potential. The first half of this study critically reviews state art developments cleaning upgrading technolog...

The primary goal of the Carnegie Chicago Hubble Program (CCHP) is to calibrate zero-point Type Ia supernova (SN Ia) Diagram through use Population II standard candles. So far, CCHP has measured direct distances 11 SNe Ia, and here we increase that number 15 with two new TRGB NGC 5643 1404, for a total 20 SN calibrators. We present resolved, point-source photometry from Space Telescope (HST) ima...

As the living standards of Chinese people have been improving, the energy demand for cooling and heating, mainly in the form of electricity, has also expanded. Since an integrated cooling, heating and power supply system (CCHP) will serve this demand better, the government is now attaching more importance to the application of CCHP energy systems. Based on the characteristics of the combined co...

Compressed air energy storage (CAES) is increasingly investigated as a viable technology for balancing electricity supply and demand. The main purpose of CAES to overcome the intermittent problem when renewable introduced. However, round-trip efficiency (RTE) system commercially developed still low (around 54 %) requires further improvement. This study proposed novel combined cooling, heating p...
