1052 Emissions Reductions

By increasing the efficiency of energy use, CHP can significantly reduce emissions of criteria pollutants, such as NOx and SO2, and noncriteria greenhouse gases, such as CO2.

Figures 10.7 and 10.8 show NOx and CO2 emissions comparisons respectively by power generation technology and fuel type. While reductions in both NOx and CO2 result from moving from solid and liquid fuels to natural gas, the figures show the added reductions that efficiency can provide. CHP technologies can significantly reduce emissions and compare favorably to advanced low-emission central station technologies such as gas-fired combined cycle.

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
