  • Hydrogen-diesel dual fuel combustion in a direct injection diesel engine

    Hydrogen is expected to be one of the most important fuels in the near future to meet the stringent emission norms. Hence in the present study, the combustion of hydrogen-diesel duel fuelled engine was investigated. Hydrogen was injected in the intake port during the suction stroke and diesel was injected inside the combustion chamber near TDC. The start of injection for hydrogen was maintained ...

  • Energy directives update

    December 2008 has seen the agreement of a significant range of new energy and climate change measures by EU ministers. The EU Energy & Climate Change Package, as agreed 17th December 2008, includes; Energy Efficiency, EU ETS Phase III, Effort-sharing in non-EU ETS sectors, Renewable Energy, Fuel Quality and Carbon Capture & Storage. However, not all Directives were new or were changed, some were ...

  • Fuel Homogenization

    The structure of the financial expenses of automotive businesses and boiler plants is quite varied, though it still allows to identify the main expenditures. First of all, it is the fuel, which accounts for no less than 40% of all costs. Fuel homogenization devices are designed to increase the quality of combustion, thereby saving resources. Homogenized fuel features good performance, ...

  • EC explains its proposed new directive on cutting fuel consumption in road vehicles

    The Commission's revised proposal for a Directive on the promotion of clean and energy efficient road transport vehicles introduces sustainable economics into public procurement of vehicles and transport services. Public authorities will use criteria for lifetime costs for energy consumption, CO2 emissions and pollutant emissions when they procure vehicles. A harmonised methodology will be ...

  • Background: EU electricity and gas directives

    3.rd Energy Market Package, proposed September 2007 September 2007 the EU Commission proposed a revision of the electricity and gas market directives with amendmets of the directives on electricity and gas markets and the directives on cross-border trade of electricity and gas. The main changes are that all countries must have independant regulators of the electricity and gas markets, that these ...

  • Effect of reforming on the overall efficiency of a solid oxide fuel-cell based power plant system fed by methane

    In the present work, energy and exergy system analysis are used to estimate the thermodynamic performance of a SOFC system fuelled by methane. More precisely, the present work examines in detail the influence of the presence or absence of the reformer within the whole apparatus and the consequent energy and exergy losses due to the reforming process. It was found that the exergetic efficiency for ...

  • Efficient steam production in paper mills

    The paper and pulp industry is an energy and emission intensive industry. Steam is an essential part of the paper making process with steam boilers, steam distribution systems and other processes accounting for a large percentage of a paper mill’s energy costs. Useful energy is often lost from boilers and process equipment such as heat exchangers, dryers, evaporators etc, as well as from ...

  • The 14 best states for energy efficiency

    Once a “token gesture,” energy efficiency is now increasingly becoming a “first fuel” — the resource utilities seek before any other, even before renewable energy or other in-favor generation sources. So says the report, “Meeting Aggressive New State Goals for Utility-Sector Energy Efficiency: Examining Key Factors Associated with High Savings,” issued today by the American Council for an ...

  • Above all, biogas must be efficient

    Herning Bioenergi and Bigadan use blower technology made by AERZEN In Denmark, AERZEN blowers create the link between biogas plant and dairy plant. Until 2020 Denmark wants to reduce its gross energy consumption - regardless of the aspired economic growth - by 12% compared with 2006. Another goal: Until 2050 the own power and heat requirements shall exclusively be served by ...

  • Pragmatic Efficiency Limits for Internal Combustion Engines

    This article gives an overview of the thermodynamic principles demonstrating that the maximum efficiency theoretically possible with a hydrocarbon fueled internal combustion engine is one hundred percent. From this basis the focus turns to articulating irreversibilities that naturally occur within the processes of converting the chemical energy in the fuel into shaft work. These losses are ...

  • Assessing Feasibility of Direct Drive Technology for Energy Recovery from Digester Biogas

    ABSTRACTThe Regional Municipality of Waterloo completed a study, with support from Environment Canada, to evaluate the feasibility of using direct drive technology to recover energy from digester biogas. The study identified that a 150 HP engine, operating at 54 % load, could be supported by the estimated gas production of 1560 m3/d with 63 % methane by volume. ...

  • International plan makes efficiency top priority

    By Elisa Wood July 8, 2010   While several clean energy technologies play an important role in reducing carbon dioxide emissions, none compare to energy efficiency, according to a new report by the International Energy Agency.   “Increasing energy efficiency, much of which can be achieved through low-cost options, offers the greatest potential for reducing ...

  • Domestic heating systems are more efficient with Scalewatcher

    In hard water areas plumbing, hot water systems and appliances quickly become encrusted with limescale resulting in increasing energy bills and the early renewal of boilers and appliances.  The award-winning, patented, Scalewatcher water-conditioner, from Scalewatcher North America, offers a simple and permanent solution to limescale thereby reducing energy bills and making heating systems ...

  • US Dominance in Alternative Energy and Energy Efficient Technologies

    20 years ago there were very few people who would have thought that international competitiveness to be number one would involve much of anything outside military, aerospace or, computer technologies. The last thing anyone probably expected would be a race to be the top producer of the most efficient and environmentally safe technologies on earth. Yet that is precisely what is taking place right ...

  • Energy efficient ferrero group invests in GEM

    Thermal Energy International Inc is pleased to announce that Energhe S.p.A. has made Thermal Energy International’s GEM venturi orifice steam traps its steam trap of choice following rigorous testing at Ferrero Group’s headquarters in Alba, Italy.   Founded in 2007 by parent company, Ferrero Group, Energhe S.p.A. develops energy efficient projects and financial savings for ...

  • The real power behind today’s energy efficiency industry?

    President Barack Obama recently pushed for increased energy efficiency in his State of the Union address. His endorsement is a plus, no argument. But it may not be the federal government that drives the industry’s next growth spurt. Increasingly, the push for clean energy seems to be more grassroots, from the city and community. Consider these significant ...

  • Energy Efficiency, Pollution Prevention, and the Bottom Line

    Introduction For many years, efforts to promote energy efficiency and pollution prevention (P2) traveled on parallel paths. Most energy efficiency advocates considered only the energy savings aspects of their projects and most proponents of P2 did not include energy on their list of sources of pollution. More recently, the two groups promoting energy efficiency and P2 have begun to realize the ...

  • The isoengine: realisation of a high-efficiency power cycle based on isothermal compression

    A novel high-efficiency internal combustion engine for power generation and direct-drive applications is being developed. Distillate-fuelled power plants in units of 7 MW electrical output are predicted to reach a net electrical efficiency of 60%. An efficiency of 58% is targeted for the gas-fired version. This compares with a net electrical efficiency of about 45% for advanced reciprocating ...
