Marginal lands

Energy crops could cover energy demand in surplus agricultural lands

A brand new study (2013) found that the projected energy demand (2035) in developing countries, can be covered with energy crops in surplus agricultural lands, then not competing with food production. 

Breaking: biofuels voted 6% Cap on crop-based biofuels in transport

The European Union assembly fixed a 6 percent limit on the use of crop-based biofuels in ground transport, seeking to spur the development of clean fuels from non-food sources.

Biofuels sustainability: Not all alternatives are the same.

From food debate and land use changes effects to biofuels sustainability, a lot of scientific findings show great differences among alternatives. We joined best scientific information. 

Biomass Power Generation growing by 2020

Worldwide revenue from biomass power generation will reach $11.5 billion annually by 2020. Feedstock cost at the gate of the facility is the key issue. 

Land use effects: More land is available where more biofuels are produced. Are models wrong?

A very recent research publication  found harvested area with food crops to be increasing during 2000-2010 period simultaneously with biofuel expansion.

Miscanthus or cheaper perennial bioenergy crops in higher latitudes?

Miscanthus among perennial bioenergy crops in northern EU, has been promoted during last decade for heat and power production. After cultivating more than 12,000 hectares in UK, too low average yields (10-12 odt/ha per year) and high costs of delivered biomass (60-140 €/odt) are becoming major constraints

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 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.
