Energy policy

The world economy depends on only two significant energy carriers, namely hydrocarbons (natural gas, gasoline and diesel fuel or heating oil) and electrical current. Whereas the primary energy supply differs greatly from nation to nation, hydrocarbons are our main means of storing energy. At present, the consumption of primary energy is globally highly dependent on fossil fuels, as shown in […]

Rape biodiesel

Biodiesel fuel was first commercially produced in a pilot plant in Silberberg (Austria) in 1985 [87]. Already in 1997 biodiesel development had been identified in 28 countries with a worldwide capacity of some 1.2 Mt/yr [88]. Meanwhile world biodiesel production is rapidly expanding from 2.7 Mt in 2003 (60% EU share) to 7.1 Mt in 2006 (69% EU share). Different […]

Biodiesel as a renewable energy source

Abstract: Renewable fuels are bound to gradually replace fossil fuels. Development of biorefineries will mark the historic transition into a sustainable society in which biological feedstocks, processes and products constitute the main pillars of the economy. Energy policy facilitating the introduction of biofuels, including biodiesel, avails itself of taxation, subsidies and mandates, which are not always unquestioned. Transformation of vegetable […]

Biofuel research and development

Bioproduct R&D is currently a hot topic worldwide [29], albeit with strong economic and political conditioning. Biofuel R&D has been driven by recent regulations to reduce dependence on mineral oil (US FB4P and EU Directive 2003/30/EC). The biofuels industry faces a more than 60 year R&D delay with respect to the petrochemical industry with its advanced standards of performance. However, […]

Transesterification to biodiesel

Biodiesel (chemical name: fatty acid methyl esters (FAME), C14-C24 methyl esters; CAS No: 67784-80-9) is defined as a fuel comprised of monoalkyl esters of long-chain fatty acids derived from renewable lipid feedstocks, such as vegetable oils or animal fats, for use in compression-ignition (diesel) engines [50]. Biodiesel is not a single chemical entity. In 2003, US Congress proposed that, for […]
