In a recent reality check, scientists estimated what it would take to sequester 1 billion tonnes of carbon using BECCS based on
switchgrass feedstock.

Faster - growing root systems could allow new plants to take hold more quickly, including perennial grasses like
switchgrass and Miscanthus, which are considered viable
feedstocks for next - generation biofuel.
A team of researchers from five institutions analyzed the ability of six microorganisms to solubilize potential bioenergy
feedstocks such as
switchgrass that have evolved strong defenses against biological and chemical attack.
An experiment by Argonne National Laboratory in Central Illinois explores the potential of formerly overlooked plants such as willow and
switchgrass for bioenergy
feedstock, offering farmers a possibly lucrative use for difficult land and preventing nitrogen pollution to boot.
Advanced biofuels can be derived from lignocellulosic
feedstocks, such as agricultural waste (e.g., corn stover, wheat straw, rice hulls), agricultural processing byproducts (e.g., corn fiber or sugar cane bagasse), forestry and wood processing waste, the paper portion of municipal solid waste, or dedicated energy crops such as
switchgrass.
The most common
feedstocks will likely be agricultural wastes, such as rice straw, or natural grasses such as
switchgrass, a variety of prairie grass that is often planted on soil bank land to replenish the soil's fertility.
It seems Ma Nature has got a beef with biofuels and has tossed a wrench into the biofuel industry in the form a virus that impacts the
feedstocks —
switchgrass in particular.
The authors of the letter also say that some potential biofuel
feedstock crops — including
switchgrass and miscanthus — are perennials that sequester carbon into soil and thrive on land often not suitable for other crops.
Use of perennial
feedstocks, such as miscanthus or
switchgrass, offers...
Development of
switchgrass (Panicum virgatum) as a bioenergy
feedstock in the United States.
The next generation of bioenergy technology aims to replace current
feedstocks such as corn, sorghum, sugarcane, rapeseed, soy, and oil palm with dedicated cellulosic crops (Kszos et al. 2000; Heaton et al. 2008b), such as woody tree species and the grasses
switchgrass (Panacum vergatum) and miscanthus (Miscanthus x giganteus)(Lewandowski et al. 2000).
Though the current substitution rate is negligible, a rapid expansion is possible with the use of wood residues (urban wood, pallets, and secondary manufacturing products) and dedicated
feedstock supply systems (DFSS) such as willow, poplar, and
switchgrass.
