Benefits |
|---|---|
Uses low cost residues as feedstock |
Allows user to pay for the system through fuels savings from displacing high price electricity and heat. Modular biopower is the only form of renewable energy conversion that can use a negative cost feedstock (avoid cost of disposal). |
Flexible as to its use of biomass feedstock |
Typically requires only a software change or perhaps a modified grate design, to handle a wide variety of feedstocks. |
Gasifier uses air as the oxidant |
Air-blown systems are much less expensive since they do not need oxygen generators. |
System operates under a slight vacuum |
Negative pressure systems are much safer than pressurized systems since carbon monoxide will not be forced out if there is a leak. |
Highly automated |
Avoids reliance on humans to track and respond to a large number of complex operating variables. This not only leads to significantly increased run time, but it also eliminates the need for a full-time operator. |
Stainless steel gasifier construction |
Withstands high reactor temperatures while avoiding the use of refractory that adds substantial weight and bulk and requires periodic, extended shutdown for replacement. |
Extremely low tar production |
Low levels of tars at the front end of the process minimize the cost and complexity of downstream cooling and cleaning. |
Clean fuel gas |
Clean fuel gas provides the ability to power many different kinds of gas-based prime movers --- such as IC engines, stirling engines, thermo electric generators, solid oxide fuel cells, and micro –turbines. In addition, clean fuel gas is a prerequisite to making liquid fuels. |
High availability |
Long, continuous operation translates to increased energy production, reduced maintenance, and reduced manpower needs. |
High efficiency (electrical as well as combined heat and power) |
High efficiency maximizes the energy output from a given feedstock. This results in greater energy output, less cost for feedstock, and less cost for labor to process and handle the feedstock. Our electrical efficiencies approach 30% in diesel engines and 80% in combined heat and power applications. |
One common gas production platform can power a number of different energy conversion applications. This standard approach reduces capital costs and provides for commonality of replacement parts. |
|
Containerization |
Provides for factory assembly and testing without the costly need to disassemble for shipment and reassembly in the field. Containerization also minimizes the need for site-built structures. |
Small footprint |
Reduces siting and installation costs. |
Low emissions and non-hazardous char/ash |
Maximizes the number of locations where the system can be permitted to operate |
