Electricity

Explore the electrifying opportunity available in power production, the easiest end product to make using FastOx gasification.

Equipment

The type of electrical power production system placed in combination with a FastOx gasifier system depends on many parameters specific to each project. The system could ultimately include any combination of internal combustion (IC) generation set (genset), gas turbine, steam cycle, organic rankine cycle (ORC), or fuel cell.
 

For sub-utility systems (approximately 100 tons per day and less), Sierra Energy recommends a packaged lean-burn spark-ignition (SI) genset. This is often the most economical solution. It is possible to obtain these packaged SI engines in sizes up to 4 MWhe with electrical efficiency up to 42%.  A FastOx system could also include several of these identical genset packages in parallel for larger scale projects. In some situations, this is more economical than a single combined-cycle power plant (CCPP).
 

IC engine genset manufacturers Sierra Energy typically considers are GE-JenbacherCaterpillar MWM, and Siemens Dresser-Rand Guascor.
 

Gas turbine manufacturers Sierra Energy typically consider using are Capstone TurbineSiemens Dresser-Rand GuascorCaterpillar Solar Turbines, and Mitsubishi.
 

Fuel cell manufacturers Sierra Energy typically consider using are Fuel Cell Energy and Ballard.
 

ORC manufacturers Sierra Energy typically consider using are ElectrathermGE, and Siemens.

FastOx Gasification Syngas Vs Conventional Fossil Fuels

The clean syngas produced by FastOx gasification results in electricity production with lower specific emissions than typical fossil fuel electricity generation. Syngas from FastOx gasification breaks apart more completely than atomized liquids. Consequently, it produces less Carbon Monoxide (CO), Volatile Organic Compounds (VOC) and Particulate Matter (PM) emissions than conventional fossil fuel power plants. Oxides of Sulfur (SOx) emissions are reduced as well, as our syngas contains virtually no sulfur compounds once cleaned. Finally, syngas from FastOx gasification has a lower energy density (MJ/Nm3) than natural gas. For example, the peak temperatures observed inside the vessel are notably lower which translates to significantly lower Oxides of Nitrogen (NOx) production.

 

Impact and Potential

Electricity is one of the easiest end products to produce using FastOx gasification due to the relatively uncomplicated production system. The United States currently sends approximately 250 million metric tons of municipal solid waste (MSW) to landfills every year. Using FastOx technology, municipal solid waste alone could power close to 14 million homes. This estimate does not include other waste types generated in society, like biomass or industrial waste, which would increase this number drastically.
 

The quantity of energy produced depends on several factors. These include the type of feedstock, system configuration, and other plant specifics. One commonly requested configuration employs post-recycled MSW for electricity generation. This configuration of a FastOx system would have an estimated net production of 650 to 1,000 kWhe per metric tonne of MSW feedstock for small scale projects (assuming a genset electrical efficiency of 35%).
