CoGeneration or “Reusable Energy” dates back to 1889?
Cogeneration, sometimes called “Reusable Energy” is not a new idea
One of the first cogeneration power plant was founded by Thomas Edison in 1882. His Pearl Street Station in Manhattan not only provided electricity for more than 500 customers when it got going, but it also captured the steam by-product and sold it to local manufacturers in the Manhattan business district. By the early 1900s, CHP systems produced about 58% of the total on-site electrical power generated in industrial plants in the U.S.
It’s not a new idea but “reusable energy” is gaining momentum once again
A process called cogeneration or CHP (combined heat and power) has been gaining considerable attention because it generates electricity by using renewable energy sources (reused thermal energy). Due to the efficient use of “waste heat”, the combined heat and electricity generation can save up to 70 % of the energy contained in the fuel compared to separate electricity and heat generation.
How does it work?
Rather than wasting thermal energy, a (CHP) plants recovers otherwise wasted thermal energy and generates electricity and useful heat, from a single primary source, often natural gas.
Why Use Cogeneration?
While policy makers talk about wind, solar energy and other “renewable” technologies, few appear to understand and appreciate the potential of “reusable energy” or cogeneration. In countries such as Denmark, the Netherlands and Finland, cogeneration has been encouraged by government incentives and it makes up to 40% of their total electricity generation.
There are several benefits to using cogeneration. The main reasons to use CHP are to save energy and costs by reducing fuel consumption, thereby reducing carbon emissions. A win for industry and a win for the environment.
We recommend Suncor’s video which explains the CoGeneration process brilliantly:
