According to the Environmental & Energy Study Institute, there are more than 4,100 CHP systems being employed in the U.S. alone as of 2013.
What is a Combined Heat and Power (CHP) system?
CHP systems combine the production of thermal and electric energy into one seamless process, requiring much less fuel than conventional methods where heat and power are produced individually/separately. This results in a much more efficient and eco-friendly approach to power generation, taking the place of other methods like purchasing power from the grid or employing an onsite furnace or boiler.
Combined Heat and Power systems can use a variety of fuels that are renewable- and fossil-based, and can achieve energy efficiencies of over 70 percent – compare that to separate heat and power generators which are an average of less than 45 percent efficient.
CHP systems are employed primarily in large industrial, institutional, governmental and commercial establishments where a continuous, reliable thermal and electrical power supply is most critical. This includes food processing plants to large refineries, hospitals, retirement homes, water supply and wastewater treatment facilities, chemical plants, office buildings, hotels, airports, college campuses and more.
There are 3 key benefits to using a CHP system compared to other conventional methods:
1. Reduced Costs
When compared to conventional methods of energy generation, CHP saves its purchasers more money. In fact, according to McKinsey & Company, an additional 50 GW of capacity (which is equal to around half of the current nuclear generation capacity in the U.S. alone) could be cost effectively employed by the year 2020 and would be able to produce annual savings of $77 billion.
2. Reduced Greenhouse Gas Emissions
Because less fuel (up to 75%) is required to produce energy , combined heat and power technology creates significantly lower greenhouse gas emissions as well as other air pollutants compared to other conventional methods.
3. A Dependable Energy Supply
A disruption in heat and power supply at large institutional or governmental facilities poses a huge threat to the health and wellbeing of the public; not to mention the harmful impact it would have on the economy.
The right CHP systems can provide reliable, 24/7 electrical and thermal power even when the grid is down. According to an article from the Environmental and Energy Study Institute, extended power outages as a result of Hurricane Sandy in the Northeast as well as other recent hurricanes on the Gulf coast lead to billions of dollars worth of economic losses in addition to its threat to the well-being of the public.
However, CHP played a critical role keeping the lights and heat going in New Jersey, New York, and Connecticut during Hurricane Sandy – with CHP-powered hospitals, nursing homes, wastewater treatment plants and apartment complexes able to continue meeting the needs of the community. Not even back-up generators were able to deliver energy during the outage.
The article also mentions how the DOE Gulf Coast Clean Energy Application Center reports that CHP systems have also prevailed during many other instances of natural disaster, like hurricanes Katrina and Rita in Louisiana, as well – proving to be far more dependable than emergency back-up generators.
For Reliable and Efficient Heat and Power, CHP Systems Are The Answer
Having a dependable and steady access to heat and power around the clock is paramount in order to operate a productive and safe facility. CHP systems provide a resilient and continuous supply of energy that allow establishments to continue running during grid outages, pose few geographical limitations and can ultimately save power purchasers a lot of money.
