HCNG

HCNG (or H2CNG ) is a mixture of compressed natural gas ( CNG) and hydrogen ( H), which is developed for over 20 years. The hydrogen content is up to 50 percent by volume, but usually about 20 %. It is used as a fuel for internal combustion engines. Here, this fuel can be burned in any conventional natural gas engine in principle.

Benefits

Through the hydrogen fraction combustion and improves performance, and reduces harmful emissions. Thus, the emission of nitrogen oxides (NOx), about 50%, the. Of carbon dioxide to 7% compared to the combustion of natural gas, pure drops Compared to modern diesel engines of nitrogen oxide emissions are reduced by as much as 65%, and particulate emissions by 80%.

Hazards

A hydrogen content of less than 50 percent in the mixture has the same HCNG leakage and Enflammungsrisiken as pure CNG. Despite the hydrogen in the mixture, no additional measures are needed to prevent hydrogen embrittlement of the materials that come into contact with the mixture.

Station network

HCNG stations exist between mountains and Romerike in Norway and along the "British Columbia Hydrogen Highway " between Vancouver and Whistler in Canada.
