Vietnam is an agricultural country with a lot of potential for biomass power materials such as straw, straw, sawdust, wood pellets … However, little is known, grass is also a biomass material. thick promises. This article will analyze the potential and value of Giant King Grass that can bring to biomass power industry in Vietnam.
Introduction of Giant King Grass and grass planting in Vietnam
Giant king grass is a new energy crop, best grown in tropical and subtropical regions. This is a perennial plant and can be harvested several times a year. Vietnam is a country with favorable climate and soil for growing this grass. Currently in Vietnam, many units have gone on to research and grow grass to serve production and many other industries including renewable energy Biomass.
According to renewable energy studies, the energy generated from one hectare of king grass is equivalent to 60 tons of coal. Giant king grass can be used as coal or oil in power plants. In the existing coal power plant, the giant king grass burns up to 20% of coal, helping to reduce carbon emissions by 20% and allow power companies to meet the requirements of reducing carbon dioxide emissions in 10 to the next 30 years.
Renewable energy crops and local production. The productivity can reach 167 tons / acre (375 tons / ha)
Good thermal value (> 3800 Kcals / kg at 26% humidity) and little ash content (<9%)
Can grow in harsh areas, less water and tropical climate, even where agricultural crops such as maize, rice can not grow.
In particular, can continue to grow in the next 6 to 7 years after planting, and the harvest made every 3 months. This is a big plus compared to other conventional fuels.
Can be harvested to produce pellets or biofuel when it is 13-16 feet tall, or every 150-180 days.
Economic value comparable to other traditional fuels
The following is a table comparing the properties of giant grass with other fuels:
It can be seen that the fuel’s ability to provide heat and moisture is not inferior to other traditional materials such as coal, wood pellets or straw, so it will be a biomass energy of interest. In addition, the flexibility in the growth environment will help this grass to meet the needs of the market.
In conclusion, this is a grass with many outstanding advantages when cultivating and exploiting for Biomass power industry in Vietnam, thanks to promising applications and simple farming methods, not too much labor. strength and resources when in progress.
For agricultural countries like Vietnam, this is a valuable potential to conduct research and development and exploitation to provide raw materials for biomass power plant industry.
