Hydrogen production from raw biomass

Hydrogen production study focused on new method by photocatalytic reforming was released by scientists in the United Kingdom.

Biomass costs lower than fossil energy (IRENA says)

Biomass costs would be lower than those of most fossil energy sources in most countries of the world. IRENA recent report reveals how technologies are reaching grid parity.

Energy crops in Germany: more perennials needed (new study, 2014)

A very recent study on energy crops in germany (September 2014) was published in BIOMASS & BIOENERGY. A review shows several advantages in perennial bioenergy crops regarding pesticides and suggest they should be promoted further.

Biofuels sustainability: a lower fossil energy in fertilizers is needed

Nitrogen fertilizers are responsible of most biofuels sustainability limitations in life cycle assessments and carbon footprint. But some very realistic strategies and new findings would help to reduce their impacts.

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.

Land use changes: new study faces the EU commission on biofuels

Following our recent post on sustainability and land use changes, we include here a new study on land use changes that challenges the EU commission regarding biofuels. 

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.

Energy crops small plots vs field plots: avoid unrealistic expectations

Small plots and research scales are not as realistic as productivity from field plots when making economic assumptions in any project. 

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.
