EEA: More bioenergy crops needed for more efficiency

A broader mix of bioenergy crops to reduce environmental impacts is suggested in last report issued by the European Environment Agency.

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. 

Land use changes and bioenergy sustainability

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. 

Sustainable bioenergy and grasslands on the edge

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.

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.

A biomass-solar hybrid plant begins operations in Spain

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. 

How to be less alarmist when evaluating biofuels sustainability

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.

WBA: “Carbon debt and ‘payback time’ of biomass are not credible”

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.
