Community Power Corporation (CPC) has developed over the past 12 years a number of modular BioMax® system technologies and products that convert a variety of biomass feedstocks into power, heat and cooling.
CPC’s automated, modular biopower products include the core BioMax® Gas Production Module that converts a wide variety of woody biomass into clean, environmentally friendly and versatile nitrogen-diluted syngas. The syngas can displace various fossil fuels by powering spark or compression ignition engine generators, or the syngas can be combusted in conventional boilers, dryers or similar equipment.
The BioMax® Gas Production Module is a highly versatile platform that can integrate with a number of gas-based energy application modules to make electricity, heat, cooling and liquid fuels. This is much like a battery pack tool that integrates with a drill, saw, sander, etc. Similarly, the BioMax® Gas Production Module can accept three different front-end feedstock conditioning modules:
- Ready-to-use, such as nutshells, pellets, etc.
- Wood chips
The primary function of the BioMax® system is to convert the photosynthetic energy stored in biomass materials (organic materials) into a clean synthetic fuel gas (~17% hydrogen, 20% carbon monoxide, 8% carbon dioxide, 2% methane and the balance nitrogen) that can be converted by engines, generators and downstream chemical processors into electricity, heat, cooling, and/or liquid fuels.
The photosynthetic energy stored in the biomass feedstock is converted to other forms of energy by means of a thermochemical reaction in a proprietary computer-controlled downdraft gasifier. The gasifier is the heart of the BioMax® System.
The gasification process is fully automated via a proprietary control algorithm and a highly sophisticated control system that has been developed and refined through thousands of hours of operations at 33 sites in the field.
The BioMax® system uses a shell and tube heat exchanger to cool the gas stream in the BioMax® Gas Production Module. Waste heat from the gas cooling is used to dry feedstock. The BioMax® system does not use any form of liquid cooling or scrubbing of the gas, eliminating the need for any water. The char/ash particles are removed by self-cleaning, passive bag-type filters and automatically stored in standard plastic bags for easy disposal. Depending on the feedstock, the recovered char/ash can be used as a soil amendment.
To date, the BioMax® has converted over 40 different feedstocks including: wood chips, wood pellets, nut shells (coconut, walnut, almond, nutmeg), orange skins, grape skins, Timothy hay, Army wet and dry packaging and feeding kitchen waste, cardboard, and plastic utensils among others. While this demonstrates the flexibility of the BioMax®, the front-end processing module and control program are always selected to meet the end-user’s feedstock requirements.
Mutliple modular BioMax® Systems can be sited in close proximity to each other or at the same site location to achieve a much higher total power output (100 kW to multi-megawatt) and monitored remotely. These “banked” installations have high conversion efficiencies reducing operating and maintenance costs.
The illustration shows the BioMax® QuadPod™ configuration. The QuadPod™ consists of up to four (4) BioMax® gas production systems housed in a single ISO container.
The “banked” BioMax® Systems (under development) consist of multiple BioMax® 100-size gasifiers in a single container to feed syngas to a multi-hundred kW engine generator, or multiple containers of multiple BioMax® gasifiers configured to supply gas to a MW scale engine generator, or a large generating, thermal and/or chemical facility.
“Banked” systems can provide significant concentrated thermal energy for large commercial cooling or refrigeration applications.
The illustration of a BioMax® energy farm (under development) shows the potential to group multiple QuadPods™ into a significant energy facility. The illustrated configuration and its characteristics are:
- 6 BioMax® 500 kW QuadPod™ Systems
- 3 Megawatts of electric power
- 57 MWh electric energy/day (80% availability)
- 192 MMBtus of thermal energy/day
- 57 tons of biomass feedstock per day
- Footprint 150 feet x 120 feet
The standard 20‘ ISO containers (modules) for a BioMax® system are typically:
- Feedstock processing and feeding (optional, the feedstock may or may not require sorting & drying)
- Gas generation and cooling
- Gas filtering
- Power generation (optional)
The advantages of the modular BioMax® system include:
- The modules can be integrated into a large number of configurations and footprints
- Standard 20’ ISO containers can be shipped to virtually any site
- The 20’ containers can be lifted and moved with a standard forklift truck
- Sub-systems and components are easily accessed in each container
- The containers protect the equipment from weather
- The electric generator is enclosed and radiates minimal noise
- Module wiring is factory installed using quick disconnect connectors for fast, error free field installation
- Standard modules mean rapid assembly
The BioMax® Systems’ stacked container arrangement is unique and makes for a smaller footprint with a high power density, easy installation, and fewer conveyances for the feedstock.
CPC is a wholly-owned subsidiary of the Afognak Native Corporation and is the world’s leading small modular biopower corporation. Its headquarters are in Englewood, Colorado.
CPC was founded in 1995 and started work in modular biopower in 1999. CPC’s was the first company world-wide to:
- Deploy automated, modular biopower systems capable of operating unattended in Energy Services Company (ESCO) applications
- Develop a prototype modular syndiesel plant
- Manufacture complete, turn key modular biopower systems in standard ISO containers
- Develop on-site energy independence solutions that can produce power, heat and syndiesel
The Afognak Native Corporation, the parent company of CPC, is an Alaska Native Corporation formed under the Alaska Native Claims Settlement Act (ANCSA), a 1971 settlement between the U.S. government and Alaska’s indigenous peoples. Afognak Native Corporation’s shareholders are the indigenous people of Afognak Island. Shares cannot be bought, sold, or traded.
Profits earned by the business ventures are returned for the benefit of the shareholders and their Native community, providing dividends and job training, scholarships and funding social services and cultural preservation programs.
In 2011, Afognak acquired the Community Power Corporation, the world’s leading small-modular biomass company. The acquisition leverages Afognak’s and its wholly-owned subsidiary Alutiiq, LLC’s expertise while expanding business activities in the energy industry.
