Switchgrass Pellets

January 30th, 2009

Switchgrass in now been taken very seriously as a biomass fuel, particularly in the US. The video below shows Switchgrass cultivation and trials. It shows how choosing the right species of Switchgrass for the right climate will maximise yields and reduce the risk of the crop loses.

Switchgrass has many advantages, firstly as the video states the large root system can help reduce soil erosion of arid land. This root system also enables Switchgrass to prosper with little rainfall. As Switchgrass is a perennial, the root system remains in the ground, more evidence is arising that this maybe a way to trap carbon back into the soil. Different Switchgrass species can be grown in a wide range of climates. Switchgrass can also be grown by simply planting a seed, and will only require planting once.

Switchgrass pellets are another possible biomass fuel. Productivity through the pellet mill compared to wood is higher, due to the materials lower density. This means less energy is consumed in the production of Switchgrass pellets compared to wood pellets. Switchgrass pellets do contain more ash, and there are clinker and corrosion issues. However these issues are no worse than our ancestors experienced with coal, and technology can be produced to work around these issues.

The PelHeat Mobile Pelletizer can process biomass including Switchgrass into fuel pellets. If you would be interested in registering your interest in the PelHeat Mobile Pelletizer and receiving updates on our progress and informed when the pelletizer is on sale please send us an email to:

Local Sustainable Energy

January 27th, 2009

Along with ‘green energy’ and ‘carbon neutral or renewable fuels’ the phase sustainable energy is a term often used. Sustainability simply refers to whether it is possible to manage the energy requirements without damaging the environment or the economy. For example wood is a renewable fuel, as you can grow more trees. However if we only used wood for energy we would consume the trees faster than they can grow, therefore this is not sustainable.

So sustainability refers to the fuel resource its self, however the process of harvesting and processing the fuel also has to be sustainable. Larger scale harvesting and possessing cannot economically process small quantities of biomass fuel resources. As raw biomass material transportation due to its low bulk density is very expensive, and excessive transportation is also very bad for the environment.

Small-scale pellet production is an economical and sustainable way to utilize relatively small quantities of local biomass resources. Raw material and pellet transportation is dramatically reduced, and it produces more local jobs.

Large-scale production is always needed to fulfil the demands of the majority. However it does have limitations, and gaps in its ability to fully utilize available resources. This is where small-scale production can make full use of the local resources, which in many cases improves local land management and reduces waste issues. What must be acknowledged is that our new energy future is composed of several technologies, including wind, solar and biomass to name but a few, and both small and large-scale operations.

Wood Pellet Stove Popularity

January 26th, 2009

Below is a video from Voice of America on wood stoves and wood pellet stoves, and the increase in demand that was seen in 2008 due to the dramatic increase in the price of fossil fuels such as oil, coal and gas. The interviewee at the begin states how when her electricity rates doubled was the prime reason for her purchase of the wood pellet stove.

The dramatic increase in demand took some wood pellet stove and wood pellet manufactures by surprise and their current supplies could not meet this demand. This is where small-scale wood pellet manufacture has a huge advantage, as it is far more flexible to market demand changes.

As is stated in the video standard wood log stoves are not as efficient as wood pellet stoves, they do not produce as much heat, have a lower efficiency and flue gases contain more particulate matter and chemically active gases. They also are less convenient to maintain and feed. In pervious posts I have summarised these issues, and why wood pellet stoves and gasification technology is the way forward.

In the video the wood pellet stove is not their main source of heat, but it can be. We heat our entire house with a 25KW Tatano boiler, and there are wood pellet boilers available that can meet the demands of any property.

Biomass Renewable Energy

January 24th, 2009

There are many different types of renewable energy, which will all play a part in our renewable energy future. Biomass is one form of renewable energy, so is wind, solar, hydro and geothermal. Each one of these renewable energies has specific advantages and disadvantages. For example wind and solar provide free energy, however this energy is not always available. Hydro renewable energy via harnessing the energy from water movement again provides free energy, however is not always practical and is only possible in certain locations. Geothermal again is a constant free renewable energy source, however certain amounts of electrical energy are required to pump the water around the system. All these renewable energy solutions are needed to power our future, however biomass is slightly different.

Below is a video on the targets the European union have set on the use of renewable resources. It clear states the importance of renewable resources.

Biomass can be upgraded into solid fuels, for example pellets, and also liquid and gaseous fuels. Biomass is a renewable source because as long as more trees and plants are grown the fuel supply is renewable. Food production is even more important than fuel; therefore there are larger resources of biomass waste from food production. This can be in the form of wheat or barley straw, even down to the trimmings from olive and grape trees. So in terms of a renewable energy source could be purpose grown for or it could be utilizing waste, which is unlike other forms of renewable energy. And the simplest and most economical way on a small local scale to utilize these renewable resources are to upgrade them into pellets. Unlike the other renewable energy forms, a biomass economy could create more guaranteed jobs, as energy is always needed.

Pellet Mill Cooking

January 23rd, 2009

From various information that I have read on the Internet, and questions I get asked, for example ‘how does a pellet mill work’ and ‘what will and will not work in the mill’ it is clear there is a lack of accurate information on how the process works. However another reason is, there are no simple answers to those questions. There are only general rules for example mill moisture content tolerances. The best way that I’ve found to describe the process is to describe it as cooking, and the pellet mill is simply your oven.

Ingredient Percentages
To make a cake you follow a set of ingredients with different percentages. The pellet mill is very similar; you need a certain percentage of water, not too much and not too little. You also need a certain percentage of binding ingredients. There maybe sufficient naturally accruing lignin, or supplementary binders maybe required.

Ingredient Consistency
Once you have your ingredients to make the cake, you mix the ingredients to produce a uniform mix to place in the baking tin. Again the pellet mill is very similar. For the pellet mill to produce uniform consistent quality pellets, your raw material must have consistent uniform qualities.

Pellet Mill Temperature
When cooking and baking you have to get the oven up to temperature before you put the cake in. The pellet mill also has to get up to temperature before quality pellets are produced.

Therefore pellet production, particularly on a low cost small scale is a skilled process. As a professional cook learns through experience and trial and error of ingredients to produce the correct cake, the pellet producer will too. Trying different percentages of moisture and other aspects in the mill to achieve the best quality pellet.

To aid our customers through this learning process and aid their education, through the PelHeat website we will provide a members section. The members section will have articles, pictures and videos on tips how to process different raw materials, improve mill productivity, improve quality and machine maintenance.

Carbon Neutral Biomass

January 22nd, 2009

Today there are lots of ‘buzz’ words to summarise new ‘green’ energy forms. The main words used are carbon neutral, or ‘reducing your carbon footprint’. Firstly carbon footprint refers to how much carbon each person produces with their life style. So simply speaking you will have a larger carbon footprint if you drive to work instead of taking the train or walking or cycling.

Carbon Neutral refers more to our topic of biomass and fuel pellets, and how it is neutral in the carbon cycle. Using fossil fuels is using carbon, which was trapped underground, and through burning, releasing it into the atmosphere. Therefore fossil fuels are not neutral but carbon positive, increasing the amount of carbon in the atmosphere. Biomass is any plant matter, which uses carbon dioxide during the growth cycle, as long as more biomass resources are grown the process is regarded as neutral, and can be used to lower each person’s footprint.

Even though biomass its self is carbon neutral, carbon is used in the process of collecting, processing and transporting. So really it is not neutral but does have a low carbon output, however in the future it is possible to be neutral by only using renewable carbon neutral energy at each stage of the process. Everyone in the future will have to focus more on their own footprint as the world’s population continues to increase. The diagram below from bioenergy.org explains the neutral process.

Wood Pellet Stove Efficiency

January 21st, 2009

Biomass whether its wood, straw, grass or another type is a carbon neutral fuel. As it is part of the carbon cycle, as long as new resources are grown no additional carbon dioxide is introduced into the atmosphere. However this is only one aspect of the story, efficient combustion is also vitally important to reduce other particulates and emissions created during the combustion process. To improve air quality and reduce chemically active gases created during combustion, wood and other materials must be upgraded and processed.

Here are ranked combustion techniques in order of worst to best:

1. An open fire of uncompressed biomass (wood logs, grass, straw)
2. An open fire of compressed biomass (pellet stove)
3. A contained fire (stove) of uncompressed biomass (wood logs, grass, straw)
4. A contained fire (stove) of compressed biomass (pellet stove)
5. Gasification Technology which pellets are an ideal fuel for

The order of these combustion techniques based on combustion efficiency also correlates to heat capture efficiency and useable heat. Gasification can produce gas to burn in a stove, or provides an opportunity to use the gas in an internal combustion engine to generate electricity.

Pellet Stove Efficiency

Upgrading resources into a pellet and burning in a pellet stove provides more complete combustion of the material and more heat is produced. A stove therefore is means on a small scale to use a carbon neutral fuel and still achieve good combustion and heat output. The stove can produce enough heat for the entire house, and the stove can be an attractive focal point.
