Clean Energy Generators

4CleanTech's preferred green energy generators are Combined Heat and Power (CHP) units. 

CHP Explained 

During the process of electricity generation, heat is commonly produced as a byproduct. This heat is typically wasted during conventional processes, making them rather inefficient. Unlike traditional methods, a CHP plant captures this heat so that it can be employed for a range of different purposes, including cooling and absorption refrigeration. Simultaneously, the CHP also produces electricity. CHP units are therefore 40%-50% more efficient than traditional power stations and make significantly better use of the fuel utilised.  

Benefits of a CHP 

There are several financial benefits when operating a CHP unit. 

Firstly, for one fuel input, two sources of energy are generated: electricity and heat. This method of cogeneration is significantly lower in price than separately imported gas and electricity.

On average, a CHP's efficiency ranges between 75%- 90% and is therefore up to 40% more efficient than a power station.

For a CHP with this type of efficiency, the customer can apply for the CHPQA scheme. A successful CHPQA application grants eligibility to a range of benefits, including the Climate Change Levy (CCL) exemption for natural gas and electricity, enhanced capital allowances, and preferential business rates.

 Unlike traditional power stations, CHPs can also be decentralised and located exactly where they are needed. This further reduces costs by approximately  3%-5%. 


From an environmental point of view, there are fewer carbon emissions with maximum energy savings as cogeneration only requires a single plant instead of two. If heat and electricity are produced separately, CO2 emissions are increased by up to 70%. 

4 CleanTech can tailor-make a solution to suit any location and offer operation and maintenance services that guarantee high performance.
