  • Industry Leaders to Support “Second Generation” Biofuels in All EU Transport Sectors
    Industry leaders to support “second generation” biofuels in all EU transport sectors Involvement of policy makers and other industries, R&D programmes, financing, communications programmes for a cost-competitive and sustainable alternative to fossil fuels Brussels (Belgium) – 4 February 2013 – The Chief Executive Officers of seven Leading European biofuel producers and European airlines launched today in Brussels a new industry led initiative to speed up the deployment of advanced sustainable biofuels in Europe. The initiative, named “Leaders of Sustainable Biofuels”, aims at supporting the development of second generation biofuels in Europe. The leaders of Chemtex, British Airways, BTG, Chemrec, Clariant, Dong Energy and UPM are joining forces to ensure the market uptake of advanced sustainable biofuels by all transport sectors. The world is taking action to reduce greenhouse gas emissions and second generation biofuels are a key part of the solution, because they are cost-competitive and with less environmental impact than fuels made from oil or natural gas. In the European Union, 10% of all fuels by 2020 must be alternative fuels, the large majority being biofuels. Second-generation biofuels can reduce GHG emissions by at least 65%. First generation biofuels, made from corn, wheat, soy or palm provide only modest reductions in greenhouse gases and can push up food prices. During the Brussels meeting the “Leaders of Sustainable Biofuels” have established a common strategy based on several actions aimed at accelerating market penetration and technology deployment and use. In particular: • Accelerate research and innovation into emerging biofuel technologies, including algae and new conversion pathways, supported by public and private R&D&D programmes.

Compared to a conventional recovery boiler a black liquor gasifier can increase the total energy efficiency of a chemical pulp mill and produce a synthesis gas that can be used for production of motor fuel. In Piteå, a 3 MW or 20 tons per day entrained flow pressurized black liquor gasification development plant has been constructed by Chemrec at Energy Technology Center. The plant has been run more than 12 000 h since 2005. One of the key parts in the gasification process is the spray burner nozzle where the black liquor is disintegrated into the hot gasifier as a spray of fine droplets. In this thesis the spray burner nozzle was characterized with high speed photography in order to visualize the atomization process of black liquor.

  • Biofuels in the Sweden
    Biofuels in the Sweden Overview of Biofuels in Sweden The main biofuels used by vehicles in Sweden are (in order), HVO (hydrotreated vegetable oil), FAME (fatty acid methyl ester), ethanol, and biogas. In recent years, the renewable energy used in the transport sector is increased, in 2014, the share was around 12.5% (11.7 TWh), up from 10.7% (9.7 TWh) the year before. The content of almost all petrol is 5% ethanol, while most diesel fuel is blended with 5% FAME and together with varying shares of HVO, resulting in a total average share of biodiesel at 13%. The share of biogas in vehicle gas is on average 74% in 2014. (Swedish Energy Authority, 2015) Share of Alternative Fuel Use in 2014 (AMF Annual Report 2014) Low blending of ethanol (13.7%); Other ethanol (high Country information blends, 2.6%); Low blending of biodiesel (incl HVO 63.9%; of which FAME 24.4% and HVO 39.5%); Other biodiesel (11.2%); Sweden Biogas (gas and small share of liquid, 8.7%) Population 9,775,572 Biofuels policy, regulations, market development GDP (per capita) $47,229 Sweden has the long-term goal of generating zero net GHG emissions by 2050. A milestone for this goal is that by 2030 Final Energy Consumption 32,38 Sweden should have a vehicle fleet that is independent of fossil (Mtoe) fuels. A governmental investigation outlined in 2013 that this Final Energy Consumption 8,33 milestone could be realized by powering around 50% of in Transport (Mtoe) passenger cars running on biofuels and 20% by electricity, and more than 80% of urban buses by electricity.

  • 2014. Overview of Second-Generation Biofuel Projects
    a look at Overview of second-generation biofuel projects Second-generation biofuels produced from lignocellulosic biomass are now one of the main technological options for reducing the climatic impacts imposed by fuels used in transportation. These processes are designed to significantly boost the quantities of biofuels available and to take over from their first-generation counterparts, given the ready availability of raw materials and their excellent environmental performances. They are already the subject of multiple pre-industrial scale projects in many regions of the world as part of R&D programs, and the first industrial installations are already operational or under construction, the majority of them in Europe and the United States. They now require a stable regulatory framework in order to progress to the industrial learning stage required for them to become fully competitive. This is why the current uncertainties surrounding regulations in Europe and to a lesser extent in the United States could delay their development. Second-generation biofuels: on their way type of process enables not only the production of to becoming an industrial reality but synthetic diesel fuel, but also of synthetic kerosene for av against a still uncertain economic iation. Lastly, the pyrolysis route to diesel production is the subject of a level of research similar to that focused background on BtL. Technologies with the ability to convert lignocellulosic The main gasoline substitute is lignocellulosic ethanol (2) biomass into second-generation (2 nd -generation) biofuels produced using the biochemical route. This is the have been the subject of major research programs over same product as the ethanol currently marketed, the the last 10 years.
