This article provides an overview of modern contract theory and discusses the implications of the theory for contracting for perennial dedicated energy crops. We discuss some of the unique challenges of contracting for dedicated energy crops used for the production of advanced biofuels and...

For the first time, we apply the wavelet coherence methodology on biofuels (ethanol and biodiesel) and a wide range of related commodities (gasoline, diesel, crude oil, corn, wheat, soybeans, sugarcane and rapeseed oil). This way, we are able to investigate dynamics of correlations in time and...

Biofuels could offer new economic opportunities for low-income countries. We use a recursive dynamic computable general equilibrium model of Tanzania to evaluate different biofuels production options and estimate their impacts on growth and poverty. Our results indicate that maximizing the...

The purpose of this study was to investigate gasification performance of four switchgrass pretreatments (torrefaction at 230 and 270°C, densification, and combined torrefaction and densification) and three gasification temperatures (700, 800 and 900°C). Gasification was performed in a...

The European Renewable Energy Directive (EU RED) requires biofuels to reduce greenhouse gas emissions (GHG) by 35% compared to fossil fuels in order to count towards mandatory biofuel quota or to be eligible for financial support schemes. This reduction target will rise to 50% in 2017. For...

The present study explores the characteristics of the literature on the algae and bio-energy published during the last three decades, based on the database of Science Citation Index-Expanded (SCIE) and Social Sciences Citation Index (SSCI) and its implications using the scientometric techniques....

This paper presents a techno-economic analysis of carbon-negative algal biodiesel production routes that use currently available technologies. The production process includes the following stages: carbon–neutral renewable electricity generation for powering the plant, algal growth in...

This paper evaluates the indirect energy-use emission implications of increases in the use of biofuels in the USA between 2001 and 2010 as mandates within a dynamic global computable general equilibrium model. The study incorporates explicit markets for biofuels, petroleum and other fossil...

The biorefinery of the future will be an integrated complex that makes a variety of products (e.g., biofuels, chemicals, power and protein) from a variety of feedstocks. The objective of this work was to evaluate the environmental benefits, compared to the traditional sugarcane ethanol system,...

Biomethane produced through anaerobic digestion of residues is classified as a second generation gaseous biofuel. A technique employed in Spain to deal with pig slurry is drying, using the heat from natural gas combined heat and power (CHP) systems. This paper examines production of biomethane...
