Combined Heat and Power (CHP): An Efficient Option for Businesses

Combined Heat and Power (CHP) |
Combined heat and power (CHP), also known as cogeneration, is the concurrent production of electricity or mechanical power and useful thermal energy from a single source of energy. CHP provides improved energy efficiency over the traditional separate production of these energy services. One of the key benefits of CHP systems is that they generate electricity as well as capture heat that would otherwise be wasted in the conventional separate heat and power generation. This captured heat can then be used for heating, cooling, domestic hot water and industrial processes which significantly improves efficiency.
What is CHP?
CHP systems generate electricity and capture heat at the site where it is used,
such as in a factory or hospital. This differs from conventional centralized
power generation where the heat produced during electricity generation is
wasted. In CHP systems, the heat is recovered and used for heating purposes
such as space heating and hot water. There are different types of CHP
technologies but they all operate on the same principle of capturing and using
the heat that is normally wasted in conventional power generation. Some common
CHP technologies are gas turbines, steam turbines, reciprocating engines and
microturbines. They can operate on fuels such as natural gas, renewable
biomass, biogas and liquid fuels. CHP systems range in size from 30 kW to over
50 MW depending on the application.
CHP Applications and Industries
Combined
Heat And Power (CHP) sees wide
application across many industries and sectors where there is a simultaneous
need for electricity and thermal energy. Some of the key sectors where CHP
delivers good returns are:
Healthcare Facilities: Hospitals need continuous power supply for critical
equipment and processes. They also have large thermal and hot water demands for
heating, ventilation, hot water and sterilization. CHP is an excellent solution
for hospitals as it meets both needs efficiently.
Colleges and Universities: Campuses require electricity as well as
heating/cooling for buildings. CHP can provide cost-effective on-site
generation while making them more energy self-sufficient.
Hotels and Lodges: CHP meets baseload electric needs as well as space heating,
hot water heating and process load for properties. It helps reduce operating
costs.
Food Processing Plants: Food and beverage production involves thermal
processing which CHP caters to along with industrial power demands.
Data Centers: Servers and data centers require reliable electricity supply
along with cooling. CHP allows utilization of heat for cooling needs like
adsorption chillers in addition to power.
Commercial Buildings: Large commercial spaces, shopping malls and office
complexes equipped with CHP gain from synergistic power and thermal generation.
Benefits of CHP
The main appeal of CHP lies in its significant efficiency advantages compared
to separate heat and power. Some tangible benefits include:
Improved Efficiency: CHP systems achieve overall fuel efficiency of 60-80% as
compared to typical grid power plant efficiency of 33-46%. This translates to
lower energy costs.
Reduced Carbon Footprint: By recovering and utilizing waste heat, CHP systems
emit lower carbon emissions than separate heat and power.
Lower Operating Costs: Capturing waste heat eliminates duplication involved in
conventional systems and leads to operational savings over the long-run.
Maintenance costs are also lower.
Enhanced Power Reliability: On-site power generation provides a reliable backup
in case of grid outages since CHP continues to run even during power
disruptions.
Improved Power Quality: CHP systems ensure high power quality without
fluctuations since generation occurs right at the point-of-use. This is
important for sensitive processes.
Government Incentives: Many governments offer financial incentives like tax
credits and rebates to promote adoption of clean and efficient CHP
technologies.
The Future of CHP
As more industries and commercial facilities look to contain costs and reduce
emissions, CHP is emerging as an attractive distributed generation technology.
Its modularity allows for scalable solutions across different applications.
Government policies also support cleaner self-generation options like CHP. With
technology advancements, the coming years will see more widespread deployment
of CHP driven by its compelling business case and environmental benefits.
Combined with greater use of renewable fuels, CHP's role in providing efficient
power and heat is set to grow in the future.
