The Role of Combined Heat and Power (CHP) in Sustainable Energy Management

Are you looking for a way to save money and help the world transition to green energy production? Combined heat and power offer the solution you’re looking for.

Is combined heat and power right for you? Continue reading to discover the amazing world of CHP.

What Is CHP?

Combined heat and power uses emerging technology to produce both electricity and heat at maximum efficiency. It uses less fuel to produce energy and doesn’t suffer the same losses as traditional methods.

When the usual methods produce heat and power separately, they lose nearly two-thirds of the energy before it reaches its destination. Since CHP produces both at once, it’s more energy-efficient, retaining 80% of the energy produced. This can help you save money on your monthly bills.

How Does Combined Heat and Power Work?

Combined heat and power uses a variety of technologies for power generation. CHP systems come in two primary configurations.

Combustion Turbine

Also known as the reciprocating engine, this model uses a heat recovery unit to increase efficiency. Natural gas, oil, or biofuel comprise the fuel options that power the generator. The recovery device captures the heat from the generator and converts it to thermal energy, such as steam or hot water. Natural gas, oil, or biofuel comprise the fuel options that power the generator.

Steam Boiler

This method heats water in a boiler and transports it to steam turbines for energy production. Because the steam is already heated, the process requires no additional methods to capture heat. Popular methods of heating the boiler include coal, oil, biogas, or natural gas.

Packaged Solutions

These all-in-one systems come ready to install, and you can obtain them more easily than traditional systems. They often include the following components:

  • Engine or fuel cells
  • A generator
  • The heat recovery device
  • Emission controls
  • Unit controls
  • Weather resistant covering

Versatility

CHP is versatile. An individual location can install the technology for their facility, or a utility company or municipality can incorporate it into a grid for multiple users. However, the farther you install the generator from the consumer, the less efficiently it performs.

Combined Heat and Power Benefits

When you install combined heat and power, you gain several benefits.

Easy Installation

Especially with pre-packaged models, installing a CHP system takes less time, effort, and money than traditional systems. The US Department of Energy’s CHP Deployment Program helps businesses and organizations find support in implementing a CHP system.

Cost Savings

Combined heat and power provides savings in multiple ways:

  • Reduced energy costs: You pay less on your utility bills because you’re receiving both heat and power from a single source. Utility companies often offer specialized rates or production incentives for facilities that use CHP.
  • Reduced installation costs: With a standardized and compact design, installation is both easier and more cost-effective. You’ll receive short-term savings with installation and long-term savings with lower energy costs.
  • Government support: Many states and municipalities offer bonds or grants for businesses that install CHP. Other popular incentives include affordable loans, rebates, or tax credits.

Energy Efficiency

Compared with traditional power and heat generation, CHP increases your efficiency by up to 40%. CHP systems operate continuously at low levels, generating power even during outages in the larger grid. The increased efficiency reduces the burden on the overall power grid, benefiting other users.

Reduced Carbon Emissions

Combined heat and power reduces carbon emissions in multiple ways, which for many companies, provides their primary motivation to install the system. CHP reduces the carbon footprint in the following ways:

  • Fuel versatility: Combined heat and power uses a variety of fuel options, including new technology in low-carbon fuels. While interest in new fuels increases, only 5% of CHP systems in the United States use these fuels. Renewable natural gas and green hydrogen provide more access to low-carbon fuels. As more companies invest in green energy research and development, CHP systems will have increasing opportunities to incorporate low-carbon fuels.
  • Reduce carbon emissions: A one mega-watt CHP system produces about 4,200 pounds of CO2 annually. Traditional fossil fuel-based power production methods generate twice that number for the same output.
  • Reduced greenhouse gases: If your business tracks its GHG emissions, you’ll benefit from their reduction when installing CHP.
  • Benefits difficult sectors: Industries that rely heavily on fossil fuels find it difficult to reduce their carbon emissions. CHP benefits the construction industry by introducing new options for multi-family homes or residential communities. While many factories and industries that rely on high heat for production already utilize CHP, it remains the most viable option until a different technology emerges.

Aids the Green Energy Transition

As the United States transitions to a greater percentage of green energy, combined heat and power systems can aid the transition in the following ways:

  • CHP fills the gaps between solar and wind power during down periods. When the wind fails to blow, or the sun hides behind clouds, combined heat and power generates a consistent stream of energy to give the renewable power a rest.
  • The system is more cost-effective than solar and wind farms, providing access to cleaner energy for communities who otherwise couldn’t afford it.
  • It mitigates the need for energy storage. Current battery and storage technology is still cost prohibitive. By supporting the micro-power grid, CHP reduces reliance on storing energy.

Is CHP Right for You?

Despite its obvious benefits and applications, some companies might find CHP difficult to implement. Industries that gain the most benefit from CHP include:

  • Commercial buildings like offices, retail stores, and hotels
  • Multi-family residential structures such as apartment buildings, nursing homes, and planned communities
  • Prisons, universities, hospitals, and military bases
  • Industrial facilities, including food processing plants, chemical factories, or ethanol production companies

CHP is the best fit for buildings with year-round electricity and heat needs. Currently, 4,700 facilities within the US use combined heat and power.

Limiting Factors

In some instances, CHP is not a cost-effective solution:

  • Single-family residences: Combined heat and power is not cost-effective when used by a single household. If you are interested in CHP for your house, consider petitioning for a microgrid for your entire neighborhood or community. As a single house in eligible climates, you’ll find installing a solar panel on your roof more affordable.
  • Warm climates: CHP works best when the user requires heat year-round. Many residential communities in desert climates realize that combined heat and power is wasteful there. However, many industries that rely on intense heat for their production process still see CHP as cost-effective, even in warm climates.
  • Green energy locations: Some locations have greater access to wind, solar, and hydropower. Since combined heat and power is an intermediary solution between fossil fuel power sources and green energy, it’s not a good fit for areas with adequate green power.
