What are perennial grasses?
Grasses are particularly suitable for biofuel. They grow quickly, they can produce a large amount of biomass in the area in which they are grown and when they are burnt they leave behind relatively small amounts of ash. They are also perennials that spread easily and can grow on poor soil.
The grasses we will look at here are:
Canary grass (Phalaris canariensis)
Miscanthus x giganteus
Switch grass (Panicum virgatum)
Canary grass (Phalaris canariensis) originated in the Mediterranean region but has been cultivated and grown in the Middle East, Europe and parts of Argentina.
It was formerly cultivated primarily for the production of bird seed but is now being considered as a biofuel due to its high yields and ability to thrive in temperate regions.
Breeding programmes have selected varieties which have a particularly high carbon content in their cell walls, giving a potentially greater energy output when burned.
Miscanthus x giganteus is a large perennial grass that can grow to a height of over four metres. It is grown in the UK and elsewhere in Europe and for several years there has been intense research into its potential as a biomass crop.
It reproduces by underground stems (rhizomes) and is considered to be an environmentally friendly crop due to its large root system, which captures nutrients, and its stems, which provide wildlife cover.
Switch grass (Panicum virgatum) is a dominant species of the tallgrass prairies in North America and is commonly used as an ornamental grass in gardens.
It thrives in harsh conditions, needing only poor soil with a low nutrient content, and undergoes rapid growth. These characteristics make it a strong candidate for biomass production.
