Bioenergy crops in marginal lands: Lower yields can have lower costs

Bioenergy crops in marginal lands have been always  a focus of attention for researchers, bioenergy companies and governments. But those areas would clearly have lower yields. Are lower cost feasible in those regions?.

Fertilizers and lignocellulosic energy crops

Lignocellulosic crops have shown in recent decades a more efficient pathway to produce energy and also lower environmental impacts. Life cycle assessments show that fertilizers efficiency is critical as well as expected yields and extractions levels when producing energy crops. We discuss implications and criteria to apply.

A Spanish 16MW straw power plant increases cereal farmer’s income

A semiarid country like Spain, often have very low grain yields and per hectare income from winter cereals. Since a 16MW straw based power plant in Bivriesca, Burgos, started 200.000 tons/yr and 12M € have been part of the local economy. 

Sustainable energy crops for biogas

The sustainable use of  energy crops for biogas is a possible solution to reduce the contribution to climate change of human activities. Power based on biomass, in particular biogas, is increasing, with a concomitant increase in the need for energy crop production.

7 alternatives as energy crops for marginal lands

Several experiences have been providing evidences on the feasibility of marginal lands bioenergy. We selected promising alternatives for biofuels, heat and electricity in semiarid environments, abandoned lands and low competitive regions.

10 “key” issues to consider about sorghum

See the 10 important considerations you need to know about sorghum.

Cut management and Harvest period of Switchgrass

The harvest period for lignocellulosic crop is a crucial aspect to be taken into account when we analyze the possibility to use this crop in relation with energy conversion system.
