CHP / Cogeneration As An Alternative Energy Resource
•
3 j'aime•4,784 vues
Combined heat and power (CHP), also known as cogeneration, is the concurrent production of electricity and useful thermal energy from a single energy source. It provides higher efficiency than separate generation by capturing heat that would otherwise be wasted. CHP can reduce energy costs for facilities that have thermal loads throughout the year, such as hospitals, universities, and manufacturing plants. Analysis shows the technical potential for CHP in the Pacific Northwest is over 15 gigawatts, which could save money while lowering emissions. CHP may be a good option for facilities interested in reducing energy use and environmental impacts.

- The Other Clean Energy - often overlooked when we think of onsite or distributed generation.
- Typical clean energy Solar Wind Overlooked resources: Energy Efficiency Combined Heat and Power (CHP) is... generating electricity right near where it will be used, and then recycling the thermal energy for heating or cooling. It's very efficient, it already supplies 10% of our nation's energy, and it can and should supply more. District Energy is... CHP, heating, and/or cooling for an entire university, office park, medical campus, mixed use sustainable development, or downtown. Over 400 building networks in the U.S. already use district energy, and the number is on the rise. Waste Heat Recovery is... capturing waste heat that an industrial site or pipeline compressor station is already emitting, and turning it into clean and renewable electricity or recycled thermal energy.
- Combined Heat and Power, or Cogeneration is a system of commercially available technologies concurrently producing both electricity and thermal energy in the form of heating and/or cooling from a single fuel. CHP is a form of local or distributed generation that takes place at or near the point of consumption. These technologies use, recycle or recover heat that would normally be lost – thereby reducing overall fuel use and reducing GHG emissions and other pollutants.
- Comparing the emissions of separate generation vs. cogeneration: There is about one half the emissions from a cogeneration system as compared to separate generation. Example based on a 5 MW gas turbine with 75% overall efficiency, as compared to typical fossil fuel based electricity with 7% Transmission and Distribution losses and an 80% efficient boiler.
- CHP plays an important role in meeting the United States' energy needs as well as in reducing the environmental impact of power generation, including:
