- CHP TECHNOLOGY HAS UNIQUE POTENTIAL TO IMPROVE THE USE OF BIOMASS RESOURCES. THIS IS IMPORTANT AS WE AIM TO DIVERSIFY OUR FUEL SUPPLY. WE WANT TO GET THE MOST OUT OF THE RESOURCES WE HAVE.
- HEAT USE IS LIKELY TO INCREASE FOR USE IN MUNICIPAL HEAT NETWORKS AND FOR INDUSTRIAL APPLICATIONS SUCH AS IN THE CHEMICAL INDUSTRY.
- CHP TECHNOLOGY IS PARTICULARLY SUITABLE FOR BIOGAS PLANTS. CHP TECHNOLOGY 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 CAN CONVERT CORN SILAGE INTO BIOMETHANE FOR ELECTRICITY GENERATION
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 POSSIBILITIES FOR THE CONVERSION OF 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 availability steadily declines. The main reason for this is that oil producers, both at state and private level, are not able to get enough conventional oil out the ground. We have previously alluded to this phenomenon in an article on peak oil and the likely prospects of the global energy industry.
This means oil producers are looking for alternatives to conventional oil and gas supplies. One way to resolve this issue is to look for alternative fuel supplies to meet the demand for energy fuel. Biomass-to-fuel is one such solution worth exploring. Basically, there are two ways to turn biomass into fuel.
One way is to process the biomass in a process called pyrolysis and remove all oxygen in the process. That allows the breakdown of organic matter and extraction of the oils. Another way to process biomass is through the slow digestion of organic matter with bacteria, as it done in Brazil, to gain bioethanol.
Some energy companies research new ways to convert plastic into fuel. 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. PYROLYSIS FOR BIOMASS TREATMENT IN COMBINED BIOGAS PLANTS COULD IMPROVE HEAT ABSORPTION AND UTILIZATION
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 OF BIOMASS CAN ENABLE BETTER ENERGY YIELDS
The main advantage of this solutions is to create syngas, which means that you will be able to create hydrogen through this process.
- CHP technology is a great advantage for countries where biomass is abundant. In many of these countries, there is a desire and need for ‘industrial’ heat. Countries and regions in colder climates with industrial networks and large biomass arisings, such as the European Union, Canada, the United States, and Russia, are likely to benefit most from CHP technology.
- Brazil is a slightly different case and relies more heavily on sugar cane. The production, distribution and use of sugarcane is somewhat different. The heat generated can be used in industry and to heat homes.
- CHP technology can help meet basic electricity and heat needs throughout the year, regardless of seasonal fluctuations and weather phenomena such as solar and wind energy. The energy resource is not as intermittent as solar and wind energy.
- We need to consider the advantages and disadvantages of using biofuel in biomass processing and compare the different technologies available on the market.
