Solar has a history of supporting renewable fuels, committing research and development toward modifying our turbines to burn various low energy fuels efficiently, including the following:
Coke Oven Gas (COG) – Waste to Energy
COG is a byproduct of the coking process used in steel mills. It is high in hydrogen with significant dust and corrosive pollutants. This waste product is captured, treated and used as fuel for the gas turbine. The gas turbine in turn produces both electricity and useful thermal energy from this gas thereby reducing local air pollution.
The process of treating waste water results in the production of digester gas. This is a methane-rich gas that can be used to produce electricity and heat the digester tanks, where the digester gas is produced. The facility can reduce its consumption of grid electricity and fossil fuels. In some instances, waste water treatment plants have become energy independent, providing all of its own needs.
Landfills – Waste to Energy
The decomposition of trash in the landfill naturally produces a methane gas that can be burned to produce electricity. Thousands of Megawatts are produced this way every year around the world, representing power production that did not require the use of fossil fuels.
