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?.
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 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.
Most recent developments and scientific evidences regarding biofuels’ impacts and sustainability but also methods to evaluate land use changes and bioenergy sustainability have been showing truly complex discussions.
There is an increasing interest worldwide on developing sustainable bioenergy alternatives for low competitive lands where food production profitability is scarce or where soils and climates are not suited for traditional activities or have no market access and low competitiveness.
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.
A unique 22.5 MW biomass-solar hybrid power plant has begun operations in Les Borges Blanques, Spain. The facility was developed by Abantia and Comse Emte and features a MAN Diesel & Turbo SE turbo generator train.
We received news from REUTER on a publication from Lancaster University researchers about biofuels modeling sustainability and environmental impacts to the air. We revised it and made some comments on the credibility of the conclusions.
The World Bioenergy Association, has published a new fact sheet on forest sustainability and carbon neutrality. The report from the World Bioenergy Association, emphasizes the fact that carbon debt and payback theories are based on unrealistic assumptions and that biomass is carbon neutral.
