Microturbine-powered Combined Heat & Power (CHP) applications increase energy efficiency from about 28% to more than 80%. Add cooling to create a Combined Cooling, Heating, and Power (CCHP) system and efficiency jumps to 90% or more.
What is CHP and CCHP?
As microturbines generate clean-and-green electricity, they produce exhaust heat. With CHP, the waste heat is captured rather than released to the atmosphere. This thermal power can be used in multiple ways: to heat buildings, dry-out manufactured products, heat laundry water and more. By recycling waste heat, companies reduce reliance on traditional grid power and boilers, and cut energy costs.
In a CCHP application, an absorption chiller is added to the system, which turns waste heat into a cooling source most commonly used for air conditioning. This further boosts energy efficiency since less utility power is needed to run air conditioners.
CHP/CCHP in Action
- Increase operational efficiency: Less fuel is needed to produce a given energy output. Additionally, CHP/CCHP avoids transmission losses that occur when electricity travels through power lines. Capstone-powered CHP/CCHP systems can achieve energy efficiency in excess of 80%.
- Cut costs: The exceptional energy efficiency of microturbine-powered CHP/CCHP systems dramatically reduces energy consumption and can save facilities considerable money on energy bills.
- Ensure reliability: Microturbine-powered CHP/CCHP systems provide high-quality electricity and thermal energy to a site independent from the power grid. The result is improved power quality and decreased impact of power outages. The systems also can provide secure power to keep businesses and occupants safe during extended power outages.
- Reduce emissions: Microturbines’ advanced combustion controls mean low emissions with no exhaust after-treatment. In addition, less fuel is needed to produce each unit of energy output, which reduces air pollution and greenhouse gas emissions. Capstone CHP/CCHP systems can run on such diverse fuel sources as natural gas, propane and biogas. The systems eliminate or reduce reliance on utility power, outdated boilers and furnaces — all of which emit significant levels of greenhouse gasses and require excessive amounts of fuel.
CHP Microturbine vs Conventional Generation
- CHP Capstone microturbines are more efficient, require 230kW of fuel, and produce much lower NOx and CO2 emissions.
- A utility and boiler are 51% efficient, require 345kW of fuel (33% more than a microturbine, which drives up operational costs), and produce significantly more NOx and CO2.
