The HENG Story

Natural gas is the least carbon intensive fossil fuel and has the lowest emissions profile of any commercially viable alternative fuel.

"Greener" natural gas
Hydrogen-enriched compressed natural gas (HCNG), that is, natural gas blended with hydrogen, has been shown to substantially reduce emissions of nitrogen oxides, carbon dioxide and particulate matter over the cleanest of all fossil fuels, natural gas. As such, it presents the opportunity to improve on the clean qualities of natural gas using existing infrastructure.

CarbonSaver™ Advantages
1. No GHG - It is important to consider the source of the hydrogen in HCNG. Generating and/or transporting the hydrogen to blend with the natural gas reduces the environmental advantages. There are a number of industrial methods of generating hydrogen from a natural gas feedstock. Steam methane reforming (SMR), partial oxidation and auto-thermal reduction are all natural gas reforming technologies that produce pure hydrogen. All of these are GHG emitting technologies. The CarbonSaver™ is less energy intensive and does not generate GHG as a stand alone process.

2. No transporting hydrogen to the site - In some cases, the hydrogen needs to be transported from a plant to the point of use for blending with the natural gas. Transportation accounts for roughly one third of GHG production. The CarbonSaver™ avoids this step by producing a hydrogen/natural gas blend on-site.

3. No blending - All other existing technologies blend pure hydrogen with natural gas. The CarbonSaver™ works in line, avoiding the need for costly and energy-consuming mixing technologies.
