In Texas, a new power plant could redefine carbon capture

A company called NET Power has begun testing a unique demonstration power plant in La Porte, Texas, that burns natural gas but releases no emissions into the atmosphere. How can it do this? The natural gas is burned in pure oxygen rather than ambient air, and the resulting heated carbon dioxide (CO2) is used to power a turbine instead of heating steam or gas.

Fuel Sources

Electricity can be generated from a wide variety of fuels: natural gas, coal, uranium (nuclear power), oil, wind, water (hydroelectric power, tidal power), solar radiation (photovoltaic power, solar thermal power), volcanic heat (geothermal power), plant material (biomass power), or hydrogen (fuel cells). The mix of fuel sources for electric generation varies greatly around the world, reflecting each country’s natural resource base as well as its politics. (See Figure 1)

Electricity: A Secondary Energy Source

science of electricity
Electricity is the flow of electrical power or charge. It is a secondary energy source which means that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources. The energy sources we use to make electricity can be renewable or non-renewable, but electricity itself is neither renewable or non-renewable.
