A brief history of the New England wood pellet
Steve Walker started his company in 1992. New England Wood Pellet has grown from a single, “little tiny mill” to a 100,000-tonne plant; a research, development, and fabrication facility called Biofuel Energy Systems; and Palmer Reload and Packaging Center, which packages product brought by rail from B.C. Walker’s next initiative is to bring boilers into the US industrial northeast commercial ...

Senate passes bill extending energy tax credits
On July 21, 2015, the Senate Finance Committee voted to pass a $96 billion package of tax extenders. The tax credits in the package include Individual Tax Extenders, Business Tax Extenders, and $16.4 billion in Energy Tax Extenders. The wind production tax credit, a $1.01 per-gallon production credit for second generation biofuels, energy efficiency credits, and a renewable electricity production ...

Biofuel - Energy Supplier of the Future?
Biofuel like biodiesel, plant oil, ethanol, bio methane or the synthetic biomass- to- liquid (BtL)- fuels everyone is talking about them. They are at present the only renewable alternative in the mobility sector and already today make up 6.1 % of the fuel consumption in Germany. However, in the past months and years biofuels had the reputation to generate a social- und environmental dilemma. ...

Exergy analysis of engines fuelled with biodiesel from high oleic soybeans based on experimental values
This study dealt with energy and exergy analyses of a John Deere 4045T diesel engine run with no. 2 diesel fuel, Soybean oil Methyl Ester (SME) and High-Oleic soybean oil Methyl Ester (HOME) at 1400 1/min. It was aimed at determining energy and exergy efficiencies, energy losses and exergy destructions of the combustion process and comparing exergetically the fuels used. The specific exergy of ...

Shannon entropy for energy technologies ex-ante evaluation
Most of the international literature has used Shannon entropy to measure the information gap. In this paper we propose a method that uses Shannon entropy to evaluate ex-ante energy technologies in a decision making process. It was called ITEM, i.e., Information Theory Energy technology ex-ante evaluation Method. The aim was to have a suitable tool for characterising the most critical project ...

Security and sustainability strategies for energy innovation systems
The peaking of world oil production presents the world with an unprecedented energy crisis. In the midst of global oil supply concerns, bio-based energy is seen as a new challenge to help solve energy shortage. Bio-based energy is seen as the next new wave for future businesses and strategies for sustainable development. The study discusses the diffusion model of the energy industry under its ...

Potential use of carbon dioxide by microalgae in Malaysia
CO2 emission, which is feared to bring more harm than benefit to the environment, can be prevented and reduced through the cultivation of microalgae. Microalga is the fastest growing organism (estimated 40 times faster than terrestrial grass) and requires a high CO2 concentration to reproduce. Thus, this work evaluates the potential of microalgae to utilise CO2. The tolerable concentration of CO2 ...

ACORE releases white paper questioning EPA RFS
On May 18, 2015, the American Council On Renewable Energy (ACORE) issued a white paper arguing that "Co-location Requirements under the RFS Impede Advanced Biofuels Development." The paper was sent to EPA. It requests that EPA clarify its definition of feedstock material under the federal Renewable Fuel Standard (RFS) so that biofuels producers that pre-process their feedstocks away from final ...

Current and future ethanol production technologies: costs of production and Rates of Return on invested capital
Considering the production goals for cellulosic and advanced biofuels in the Energy Independence and Security Act of 2007 (EISA), this study compares production costs and returns on invested capital for two current and three proposed ethanol technologies. Two methods use corn grain as the feedstock, and three use cellulosic feedstocks of corn stover, switchgrass and wood chips. Baseline levels ...

Empirical approach for the prediction of cetane number from the FAME composition
Cetane number is a prime indicator in evaluating the quality of biodiesel fuel in the realm of diesel engines. Standards have been established world wide for cetane number determination, for example, ASTM D 613 in the USA, internationally, the International Organization for Standardization (ISO) standard ISO 5165, etc. These methods are usually arduous and expensive; the values obtained are ...

Economic prospects of advanced biomass-based energy carriers in EU-15 up to 2050
Biomass-based energy carriers (BBEC) especially advanced ones such as biofuels, hydrogen and electricity from biomass are often considered to have the potential to contribute to reduction of GHG emissions. In this paper we conduct an analysis of the economic prospects and potentials of advanced BBEC in EU-15 countries up to 2050. We show which energy output from these energy carriers can be ...

DOE announces third round of START program
On February 25, 2015, the U.S. Department of Energy (DOE) announced the third round of Strategic Technical Assistance Response Team (START) Renewable Energy Project Development Assistance that provides tribal governments and entities with support to produce clean and renewable energy. The START program was launched in December 2011 and has helped 21 tribal communities advance solar, wind, ...

GHG balance of biodiesel production and consumption in EU
The promotion of biofuels as energy for transportation in the industrialised countries is mainly driven by the perspective of oil depletion, concerns about energy security and global warming. Nevertheless, the production of biofuels entails emissions to the environment coming from the different stages in the product life cycle. This paper evaluates the environmental impact of pure rapeseed ...

Assessment of the EU target on renewable energy for transport in the framework of the European vegetable oil sector
Biofuels is currently driving the interest in bioenergy sector. The recently issued Renewable Energy Directive (2009/28/EC) confirms the 10% target, set by the EC, for energy from renewable sources in transport. The European Union is the largest producer of biodiesel in the world and biodiesel is also the most important biofuel used in the EU. The aim of this paper is to investigate the biomass ...

Energy analysis and potentials of biodiesel production from Jatropha Curcas in Tunisia
Oleaginous plants such as Jatropha Curcas Linnaeus (JCL), not intended for human consumption but used for biodiesel production, could contribute to beneficial outcomes. This plant grows on poor land (arid and marginal land) and is drought resistant. Jatropha Curcas is native to South America and widely grown in South and Central America, Africa, and Asia (Achten et al., 2007; Kumar et al., 2011). ...

Scenarios for the role of hydrogen in a future energy system based on renewable energy
An all-renewable energy system for a group of North European countries is investigated by temporal simulation of the demand-supply matching for various system configurations. The role of hydrogen technologies for energy storage and fuel cell applications is studied and applied to both stationary and transportation sectors. It is shown that there is scope for considerable amounts of energy trade ...

Global bioenergy: problems and prospects
This paper explores the future global potential for bioenergy. We use energy analysis, and more generally climate change effects, as our criteria for evaluation. Since widespread use of new bioenergy is probably decades away, our evaluation attempts to take into account likely future conditions. Previous research displays large variations in estimates of both energy ratio and technical potential. ...

Parametric study of biodiesel quality and yield using a bench-top processor
Biodiesel is a renewable liquid fuel alternative to petrodiesel. It is produced by the transesterification of vegetable oil and alcohol in the presence of a catalyst. A 1.5 L bench-top biodiesel processor was constructed to study the effect of feedstock and operating conditions on the conversion and the biodiesel quality. Biodiesel was produced from several oil feedstocks using methanol and ...

Alternative fuels and sustainable mobility: is the future road paved by biofuels, electricity or hydrogen?
This paper compares 16 alternative energy chains in a Well-to-Wheel analysis including three indicators: energy use, emissions of climate gases and emissions of local/regional pollutants. The analysis includes a private car which uses natural gas, biological fuels, electricity and hydrogen, respectively. The analysis shows that an alternative which scores favourably on one indicator often scores ...
