Raven SR’s technology is significantly more environmentally sustainable than competing technologies in both process and products, and with certain feedstocks, it can be water neutral and carbon negative.
Five key features differentiate the Intellergy system from others, making it greener than any existing systems.
- It is a non-combustion system. Unlike many waste to energy processes, the Intellergy system does not use combustion, but rather a chemical process, provoked by steam, to break down waste into its chemical elements. Thus, there are effectively no emissions from the system. The technology has been approved by the Berkeley (California) Air Quality Department, which is among the most stringent in the country.
- No steam methane reforming (SMR). SMR is the reaction of methane (and other higher hydrocarbons) with steam in the presence of a catalyst to form carbon oxides and hydrogen. Most industrial catalysts are based on using nickel as the catalytic component, although platinum group metals (pgms) are used for some specific duties.
- No auto-thermal reforming (ATR). ATR is a process for producing syngas, composed of hydrogen and carbon monoxide, by partially oxidizing a hydrocarbon feed with oxygen and steam and subsequent catalytic reforming.
- Water neutral. Unlike many other systems, the Intellergy system recycles, and even manufactures, any water required, and depending on the feedstock, can be completely water neutral.
- Highest safety standards. Intellergy units are equipped with extremely sophisticated Alert Plus sensors, which can sense multiple gases, should there be any leaks, and automatically shut down plant operations without human intervention.
With its relatively small size (1100 mcf/day) the system could even utilize currently flared natural gas, eliminating a significant source of pollution, and converting it to usable, cleaner-burning fuels.

The Raven SR system is even relatively quiet, with waste entering one end of the building, and clean fuels exiting the other side.
Yields Green Outputs
The Raven SR process creates syngas from either organic wastes or natural gas – essentially anything with carbons and hydrogen in it. From this, it can produce hydrogen or Fischer Tropsch fuels, both of which can be considered renewable fuels, depending on the feedstock.
Hydrogen, when used in fuel cells, produces energy with only steam and water as by-products, making it among the cleanest energy sources known to man. Raven SR’s technology creates significant amounts of hydrogen from waste, in larger quantities than other technologies, essentially turning pollution into green energy, and at a cost that will enable the widespread adoption of hydrogen as a source of energy.
Fischer Tropsch (FT) fuels are synthetic copies of standard fuels, such as diesel, Jet A, Jet B and milspec JP-8. In an FT process, these are created out of hydrogens and carbons, rather than extracted from existing hydrocarbons (put together, as opposed to taken apart). As a result, FT fuels are more pure, and burn more cleanly.
Key features include: FT diesels have high cetane numbers, a near-zero sulfur content and very low aromatic levels.
Compared to conventional fuels, studies show FT fuels reduce NOx by 16.7% , smoke emissions by 40.3%, hydrocarbons by 49%, carbon-monoxide by 33%, and particulate-matter by 21%.
FT fuels also have higher energy content per carbon content of the fuel. FT jet fuel is less dense than conventional fuel allowing aircraft to fly further on the same load of fuel.
Bio-Carbon & Sulfur Production
Raven SR can also produce bio-carbon from organic feedstock, a pure carbon that can be used for a variety of purposes, or safely buried. From natural gas, sulfur is sequestered, which can be used as fertilizer.
