HCNG or H2CNG (hydrogen compressed natural gas) is a mixture of compressed natural gas and 4–9 percent hydrogen by energy. [1] It may be used as a fuel gas for internal combustion engines [2] [3] [4] and home appliances.
(regarding the acronyms in the above emissions chart:
AVL = Average Levels?
CNG = Compressed Natural Gas
HCNG = Hydrogen and CNG blend
NOX = Nitrogen Oxides
NMHC = Non-Methane Hydrocarbons?
CH4 = Methane
THC = Total Hydrocarbons?
CO = Carbon Monoxide)
HCNG dispensers can be found at Hynor ( Norway) Thousand palms and Barstow, [5] California, Fort Collins, Colorado (all US), Chongqing [6] and Shanxi ( China), [7] [8] Pico Truncado ( Argentina), [9] Islamabad ( Pakistan), [10] [11] Dunkerque ( France), [12] [13] Gothenburg Sweden, Rio de Janeiro [14] ( Brazil), Emilia-Romagna, [15] [16] Lombardia [17] [18] ( Italy), Dwarka and Faridabad ( Delhi), India [19] [20] [21] and the BC hydrogen highway in Canada.
HCNG for mobile use is premixed at the hydrogen station.
In the town of Nes on the island of Ameland in the Netherlands, a four-year (2008-2011) field test was carried out where 20% hydrogen was added to the local distribution net supplying a complex of 14 apartments. [22] The appliances involved were kitchen stoves, condensing boilers, and micro-CHP boilers. [23]
The use of existing natural gas pipelines for HCNG was studied by NaturalHy. [24]
To get the most out of an internal combustion engine in transportation if higher levels of hydrogen are added, modifications have to be made to the engine and the control strategy. [25] [26] [27] The hydrogen in the blend leads to lower CO2 emissions. [28]
The National Fire Protection Association 52 presently covers CNG and hydrogen fueling stations. Blends with < 20% hydrogen by volume are treated identically to CNG. [29] For the use of blends with more than 30 [30]-40 % of hydrogen in volume [31] decision support tools [32] for the design are used to ensure safe use.
