There is not easy one grade of biomass pellet energy, there are multiple quality grades based mainly on the percentage of ash the biomass pellets generate post combustion. For case the highest grade of wood pellet energy are known as premium biomass pellet energy. This grade of biomass pellet produces an ash content below 1%, generally normally around the 0.5% mark. Now, this ultra low ash content is only achieve by way of using very selective biomass resources, with no bark, as bark will amplify the ash content of the pellets. Premium wood pellets demand the highest fee point, not only as they create the lowest ash content of any pellet energy, but also because those same biomass resources are in high demand. Particle board manufactures plus several other industries also used the same raw material. This therefore increased the price of the raw material owing to increased competition. Now at this time the pellet fuel market is relatively small, along with the volume of sawdust created from timber processing is adequate generally to support the needs of pellet fuel manufacturers.

However, within recent years issues have arose by means of sufficient sawdust resource. For case in point, when the US housing market crashed, housing production stopped as well as so did the demand for production timber. As no timber was being processed, this also meant there was no waste sawdust created which is the raw matter supply for practically all premium biomass pellet manufactures. This meant the value of sawdust went through the roof, along with also there simply wasn’t sufficient to support the pellet market. This meant two things, firstly the charge of premium wood pellets sky rocked, along with secondly supply issues were common. Many US pellet suppliers were sending what little supplies they had over to Europe, as they could demand higher prices. However this further escalated the problem in the US. That issue is no longer present as the housing market is now in rival, plus the same circumstances are unlikely to happen again. However, important lessons need to be learnt from this scenario. An additional issue which also contributed to the high demand plus high pellet prices, is that most pellet consumers cannot use any supplementary grade of pellet fuel additional than premium pellets. This is because most pellet stoves are designed with boundaries. Consumers by means of more pellet fuel flexible stoves could choose other grades of wood pellets when the charge of premium pellets is very high. In the future it will be more common to use extra grades of wood pellets. For case in point, here at PelHeat we use predominantly wheat straw pellets which help support local farmers.

The future of the wood pellet fuel market cannot simply depend on premium biomass pellets. If so pellet supply problems will become common, prices will be high in addition to by will devalue the reputation of the pellet industry. Other forms of wood can be used to produce energy pellets, for case in point willow. Willow in the form of short rotation coppice can be grown very quickly along with generate some very high yields. The pellets due make a a little higher ash content that premium pellets, on the other hand the prices would be far more responsible. Wood will play a more significant role.
