• What output can I expect?

    In addition to the rated electrical power there is process heat. A typical 1MWe system will provide around 1.8Mw of heat recovered from both the generator set exhaust (550 degC), the engine radiator (75 degC) and the heat from gas cooling. This heat can be utilised for any purpose, such as a district heating scheme, wood chip drying, crop drying, greenhouse heating, etc..

  • What else will I need to operate a system?

    Electric power - at start-up a source of 3 phase electricity (grid or small diesel or gas genset) is needed for the electricial control and data systems and the start-up blower.                                  Water Supply - the system uses a small amount of clean water.

  • What are the economic benefits of a Powermax project for me ?

    Powermax gasification plants tackle two major local problems: elimination of local waste and cost of energy. By converting local feedstock into energy you lower your costs and you create new revenues (i.e. selling electricity on the grid). Energy produced through Powermax gasification is renewable and is supported by your local renewable energy support policies.This model of circular economy is also an opportunity to increase your energy independence and it creates local employment.

  • My gasification plant meets tar related operational problems, can Powermax help me ?

    Powermax doesn’t provide expert services on plants operating with other technologies. Powermax can assess how Powermax gasifier or Powermax gas purification system could substitute your initial technology. However, we usually recommend replacing both gasifier and gas conditioning unit . In extreme cases, engine and biomass preparation units should be adapted.

  • Is Biomass Gasification a New Technology?

    The gasification process has been used for well over 180 years. Until the widespread availability of natural gas in the 1950’s, coal gasification was used to produce the gases used in many city street lights. Commercial development was not seriously explored for decades due to the expanding use of less-expensive petroleum-based products. During the oil crisis of the 1970’s, research and development in biomass gasification technologies were once again brought to the forefront.

  • What Makes Biomass Gasification environmentally friendly?

    Biomass is organic matter- and Biomass energy development likes to take what is usually thrown away and turn it into energy. Our technology, the Powermax Gasification Process allows business and industry to operate “off the grid” using their own waste stream (pallets, boxes, paper), or materials from agriculture such as farming, milling and ranching. We use clean technology to take the stored energy from these materials and create heating, electricity, even cooling through CHP (Combined Heat and Power).

  • What are the benefits to the local economies touched by Powermax’s projects?

    Powermax can produce dozens if not hundreds of employment opportunities for local communities when a plant project is developed. There are a number of different sectors where jobs can be created: construction, farming, harvesting, feedstock transportation, feedstock preparation and plant maintenance. Because often times our plants will be built in rural areas, the impact can be very welcome and have a dramatic improvement on the local economy.

  • What can the gas produced in the gasifier be used for?

    The gas mixture produced by the gasifier can be used for process heating applications by operating the gasifier in a forced draft (positive pressure) mode and passing the gas directly to a burner on a boiler to make steam for an electrical turbine generator or directly to an internal combustion engine.

  • What is in the gas that comes out of the gasifier?

    The gas from the gasifier (Syngas) is basically composed of carbon monoxide (CO), hydrogen (H2), and nitrogen (N2). The CO and H2 is the combustible portion of the Syngas. It is used similar to natural gas, but it typically has lower energy content. This makes it an effective way to transfer the energy in the feedstock into Syngas to run a steam turbine or generator. Therefore the Syngas is cleaned and it is piped to the turbine or genset, the exhaust is cleaned with state-of-the-art emission control equipment after it has been burned as a fuel. In this way, reliability of the control equipment and quality of the exhaust gas stream are assured to meet all applicable air quality standards.

  • What’s the advantage of biomass gasification over production of biofuels?

    A Powermax gasifier can accept a range of feed stocks and thus the technology supports a bio-diverse resource base rather than a monoculture energy crop. However the energy density of the gas is far lower than that of liquid bio-fuels, making it more suitable for stationary applications than transport. Biomass production also removes the same amount of CO2 from the atmosphere as is emitted from gasification. While other biofuels technologies such as biogas (from landfills) and biodiesel (from agricultural sources) are carbon neutral too, gasification can operate on a wider variety of input materials and can be used to produce a wider variety of output fuels.

  • Why do we need biomass gasification now?

    Gasification is a clean, affordable and environmentally sound renewable form of energy that provides a solution to forest and agricultural management residue issues we have right now. Another challenge is energy security. Governments want to use their own resources to produce energy and provide energy independence. We need to displace some of the energy we are literally shipping in from other parts of the world, and, probably more importantly, wean ourselves from dependence on foreign energy suppliers.

  • Why do we need biomass gasification for renewable energy, isn’t wind, solar or other forms of renewable energy enough?

    Wind and solar power are key components to the future electricity generation mix because they are low maintenance and greenhouse neutral. Solar generation has the advantage of peaking at the same time as peak air-conditioning loads, and wind energy when networked sufficiently widely with appropriate interconnection can provide base-load generation. However, neither can provide on-demand generation for load-matching – a problem that exists in everywhere, due to our remote location and “islanded” utility generation. Biomass gasification can provide this 24 hours a day, seven days a week, and, if supplied from sustainably-harvested fuel, it can be a truly greenhouse-neutral on-demand generation system to complement wind and solar in a carbon-neutral way.

  • Do Powermax Gasification Systems Pollute? What are the byproducts from the biomass gasification process?

    1. The gasification of biomass as a feedstock produces Syngas. The Powermax gasifier is optimized to generate the maximum gas and little else. By products of the process are low-grade activated carbon or (Biochar) and some inert ash. Ideally, these by products are combined and returned to the soil as a soil conditioner re-capturing or sequestration of the carbon and nutrients in the soil. The Biochar then reduces the need for fertilizers which in turn improved the economics and waste due to farming. Waste heat is also produced by the process and can be used for water or space-heating, cooling, manufacturing processes, or for pre-drying the fuel for the gasifier.
    2. Gasification reactions produce small amount of water, present in the form vapour at the outlet of the gasifier. If the syngas is to be cooled down (i.e. for powering gas engines), water condenses in the gas conditioning unit.
    3. Tars that are separated by Powermax ESP(electrostatic precipitator) from the gas can be re-burned and used as fuel or can be sent back to reactor.
    4. The syngas is sent directly to the internal combustion engines when used for electricity, the engine combusts the gas and any post emissions are treated in the engine system and catalytic converter meeting the engine manufacturers’ specifications for emissions if needed.

  • Is this an incinerator?

    No. It heats the biomass fuel to create Syngas. The Syngas is directly consumed in an internal combustion engine to create electricity, or directly in a gas fired boiler to create steam, or other thermal applications where you can substitute Syngas for LPG or Natural Gas, not to dispose of waste.

  • Why Powermax’s projects are considered "carbon neutral"?

    All combustion of biomass, whether burned directly or heated indirectly to create a gas or liquid fuel to be consumed, creates CO2 emissions. However, many research papers have determined that the feed stocks used in a biomass energy facility that are sustainable and therefore re-grown, take carbon dioxide from our atmosphere and convert it to plant matter and release oxygen. By definition, within our plants, the carbon converted and emitted in the form of CO2 cannot exceed the amount of carbon we introduce into the system in the feedstock that was grown. Carbon dioxide is considered one of the “greenhouse gases” known to contribute to global warming and climate change. Because there is no additional carbon trapped in the atmosphere, the process is known as “carbon neutral”.

    When biomass is converted to energy with the gasification process, all of the carbon released was captured (by the biomass) during its life cycle. This result in no additional carbon added to the environment (unlike resulting carbon emissions from the processing and consumption of fossil fuels, whose carbon has been ‘locked up’ for thousands of years).


  • Can Powermax install the system in my country?

  • What feed stocks in general are suitable for the Powermax process?


  • Why does Powermax focus on biomass as a feedstock?

    Biomass is overwhelmingly plentiful. In fact, many renewable energy scientists and industry experts call the many parts of the world, “The Saudi Arabia’s of Biomass”. Additionally, there are a number of ways by which using biomass helps to clean up our environment and make it safer. Using the wood waste left by the lumber and paper industries; keeping wood waste out of landfills; “cleaning” our forests of dead trees and potentially flammable underbrush all helps to lower greenhouse gas emissions and beneficially uses something that would otherwise be wasted. Additionally, we can grow biomass, non-food energy crops which can provide jobs for farmers who want to grow their business or maybe have lost their business to competition. And remember that biomass is the oldest form of energy known to Earth – man has been using wood and other organic matter for fuel since the beginning of time.

  • How much biomass is required?

    This depends on the biomass. Grass and rice husks are light and require more biomass, but in general 1MT of dry biomass will produce 1MWHe (equivalent) of electricity.

  • How much space do I need for a plant ?

    Approximately 500-600sqm per MW installed is the required space. Cost varies depending upon the site location and site use. Meanwhile Powermax’s Biowatt Solutions can make 1MW less than 150sqm.

  • What size plants are addressed by Powermax?

    50 KWe to 3MW per module in electricity or heat equivalent; depending upon the modular product size selected, the biggest modular Powermax gasifier can produce up to 12,000 m3 per hour of Syngas. The BTU value of the gas is dependent on several factors including energy contained in the biomass and the moisture content.
