Enriched hydrogen enriched CNG fuel is going to be promising fuel in near future potentially replacing CNG. The most important advantage is present fuel developed can be retrofitted without any modifications in present CNG engines. With addition of 20% of hydrogen to CNG Carbon emissions are claimed to be 20 % lesser as per testing results by IOCL, India [1]. Very commonly Steam Methane Reforming units (SMR) are used to produce hydrogen required for HCNG fuel. However it has been found that due o high temperatures during combustion NOx levels are not much reduced with used on enriched HCNG fuel. In some cases NOx level are also found reduced drastically with no after treatment needed for the exhaust gases. The paper focuses on methods of producing hydrogen, characteristics of HCNG, and some measures for improving thermal efficiency and power, with reduction in emissions. Many counties like China, US, Canada, Brazil along with India are promoting used on HCNG fuel. Since use of hydrogen in near future is not possible HCNG blends can be very useful.
