A comparison of hydrogen-enriched natural gas (HCNG) and compressed natural gas (CNG): Based on ANOVA models
International Journal of Hydrogen Energy(2017)
摘要
Hydrogen enriched natural gas (HCNG) is widely studied in the energy field. It has two good characteristics inherited from hydrogen and compressed natural gas (CNG): 1) relatively cheap; and 2) operational safety. It also can reduce the emission of NOx and HC. Hence, it is a good alternative hydrogen transitional fuels. However, there is very limited work done by statistical analysis on HCNG and CNG. To address with this issue, we use analysis of variance (ANOVA) analysis to study the HCNG and CNG as fuel, and propose three statistical models tailored to the data of CO and CO2 emissions produced by HCN and CNG from year 2000–2015 from different industry sectors and different regions in China. Through the analysis, we concluded that CO and CO2 emissions produced by HCNG are statistically significant less than CO and CO2 produced by CNG.
