CHP TECHNOLOGY HAS AN ENORMOUS POTENTIAL TO CONTRIBUTE TO RENEWABLE ENERGIES.
THE CHP TECHNOLOGY IS PARTICULARLY SUITABLE FOR BIOGAS PLANTS AND IMPROVES THE ENERGY EFFICIENCY OF THE PLANT.
A few years ago, biomass was just a minor branch of the energy industry. Noone would have ever considered to invest in pyrolosis plants. Now, a growing number of researchers try to find new ways of how to convert biomass into fuel. Agricultural producers have also gotten much more involved in the energy industry as biogas plants allow farmers to produce their own electricity. But it doesn’t end there. Brazil has an established sugarcane production and processing industry that accommodates the needs of millions of transportation companies and car drivers. Brazil’s sugarcane industry also makes a substantial contribution to the fuel sector and primary energy consumption. Depending on exact processing techniques it may or may not have good fuel efficiency.
In Europe we tend towards biogas plants. Biogas plants can serve as energy storage facilities. Something few people in the energy industry often think of is we can upgrade biogas plants to serve as carbon sinks in order to increase fuel output from silage, or to repurpose them as CHP plants. CHP techniques may be suitable to biogas and biomass plants. They often complement each other, which means we may be able to diversify and create different energy products for different customer segments.
1. Biogas Plants Convert Maiz Silage Into Biomethane To Generate Electricity
Biogas plants have become commonplace. The way they operate is to turn corn into corn silage in order to produce biomethane. The biomethane is fed into the gas network where it can contribute to fuel independence.
A major concern is corrosion of the distribution network, that is caused by the amount of sulfur present in the gas. This may lead to higher maintenance costs for the network operator. But the very fact that we can actually turn biomass – such as corn – into biomethane I think is a great step forward. This would certainly not have been possible in the past.
2. New Opportunities Open Up Turning Biomass Into Fuel
Biomass-to-fuel can add to the world’s fuel supply. This is even more important at a time when fossil fuel use steadily declines because we are not able to get enough oil out the ground. I have previously alluded to this phenomenon in an article on peak oil.
This means oil producers are looking for alternatives to conventional oil and gas supplies. Basically, there are two ways to turn biomass into fuel.
Some energy companies research new ways to convert plastic into fuel and I added the link below under the references section. The aim is to create fuels that reduce overall CO2 footprint, and at the same time make good use of certain plastic waste fractions that no longer add value as end user products and cannot be reutilized as plastic bottles for example. Only certain types of plastic would be suitable for this.
3. Pyrolsis for Biomass Adjacent to Existing Biogas Plants
Pyrolysis is a good way to convert plastics into fuel. At the same time you are creating a lot of heat that can be used for anaerobic digestion in facilities nearby. Increasingly engineers become aware of the potential to combine facilities and make use of residual products.
4. Plasma Gasification Adjacent to Existing Biogas Plants
The main advantage of this solutions is to create syngas, which means that you will be able to create hydrogen through this process.
