  • Natural Gas Vehicles Myth Vs. Reality
    INNOVATION | NGV NATURAL GAS VEHICLES MYTH VS. REALITY Transitioning your fleet to alternative fuels is a major decision, and there are several factors to consider. Unfortunately, not all of the information in the market related to heavy-duty natural gas vehicles (NGVs) is 100 percent accurate. The information below aims to dispel some of these myths while providing valuable insights about NGVs. MYTH REALITY When specifying a vehicle, it’s important to select engine power that matches the given load and duty cycle. Earlier 8.9 liter natural gas engines were limited to 320 horsepower. They were not always used in their ideal applications and often pulled loads that were heavier than intended. As a result, there were some early reliability challenges. NGVs don’t have Fortunately, reliability has improved and the Cummins Westport near-zero 11.9 liter engine enough power, offers up to 400 horsepower and 1,450 lb-ft torque to pull full 80,000 pound GVWR aren’t reliable. loads.1 In a study conducted by the American Gas Association (AGA) NGVs were found to be as safe or safer than vehicles powered by liquid fuels. NGVs require Compressed Natural Gas (CNG) fuel tanks, or “cylinders.” They need to be inspected every three years or 36,000 miles. The AGA study goes on to state that the NGV fleet vehicle injury rate was 37 CNG is not safe. percent lower than the gasoline fleet vehicle rate and there were no fuel related fatalities compared with 1.28 deaths per 100 million miles for gasoline fleet vehicles.2 Improvements in CNG cylinder storage design have led to fuel systems that provide E F range that matches the range of a typical diesel-powered truck.

    Natural Gas in the U.S. Economy: Opportunities for Growth Robert Pirog Specialist in Energy Economics Michael Ratner Specialist in Energy Policy November 6, 2012 Congressional Research Service 7-5700 www.crs.gov R42814 CRS Report for Congress Prepared for Members and Committees of Congress Natural Gas in the U.S. Economy: Opportunities for Growth Summary Due to the growth in natural gas production, primarily from shale gas, the United States is benefitting from some of the lowest prices for natural gas in the world and faces the question of how to best use this resource. Different segments of the U.S. economy have different perspectives on the role natural gas can play. Suppliers, which have become the victims of their own production success, are facing low prices that are forecast to remain low. Some companies that have traditionally produced only natural gas have even turned their attention to oil in order to improve their financial situation. Smaller companies are having a difficult time continuing operations and larger companies, including international companies, have bought into many shale gas assets. Prices have remained low even as consumption has increased, in part, because producers have raised production to meet the demand and because companies have improved efficiency and extraction techniques. Some companies, many with large production operations, have applied for permits to export natural gas. This has raised concerns from consumers of natural gas that domestic prices will rise. The debate regarding exports is ongoing. Industries that consume natural gas have seen input costs drop, and some have heralded low natural gas prices as the impetus for a manufacturing revolution in the United States.

  • What Is the Minnesota Clean Fuels Policy?
    RENEWABLE NATURAL GAS IN A MINNESOTA CLEAN FUELS POLICY Fall 2020 This case study, prepared by the Great Plains Institute, explores how renewable natural gas could perform in a Minnesota clean fuels policy. What is the Minnesota clean fuels policy? Led by the Great Plains Institute, the Minnesota clean fuels policy (CFP) is a proposed market-based policy to reward any fuel that could offer a greenhouse gas advantage in the transportation sector, without picking winners or losers. It would reduce the use of higher-carbon fuels and support commercial deployment of lower-carbon fuels, including biofuels, natural gas, and electricity for vehicles. A CFP, like the California Low Carbon Fuel Standard, sets a standard for reduced carbon intensity of transportation fuels over time, otherwise known as a baseline carbon intensity standard. Carbon intensity is a measure of the greenhouse gas emissions associated with the production of a specific fuel. Fuel producers receive incentives in the form of credits from lowering their carbon intensity through production process efficiency improvement, switching to lower-carbon fuel or feedstocks, and other mechanisms that decarbonize the supply chain. These changes reduce overall greenhouse gas emissions in the transportation sector. Fuel producers that do not meet the annual standard must purchase alternative fuel or credits to comply with the program while those that are under the standard generate credits based on the carbon reduced, creating an “opportunity zone” as demonstrated in figure 1. Figure 1. Clean fuels policy market logic Figure 1 shows the carbon intensity of the standard becoming more stringent over time and two example low carbon fuel pathways, Fuel A and Fuel B.

  • Improving Performance of Compressed Natural Gas Fueled Passenger Car Engine by Addition of Hydrogen
    Journal of Scientific & Industrial Research Vol. 77, January 2018, pp. 61-65 Improving Performance of Compressed Natural Gas Fueled Passenger Car Engine by Addition of Hydrogen A K Sehgal1*, M Saxena2, S Pandey3 and R K Malhotra4 *1Indian Oil Corporation Ltd, Faridabad, India 2Univeristy of Technology and Management, Shillong, India 3University of Petroleum and Energy Studies, Dehradun, India 4Petroleum Federation of India, New Delhi, India Received 06 October 2016; revised 05 June 2017; accepted 07 October 2017 Hydrogen is a clean fuel that can be used as sole fuel or blends with compressed natural gas (CNG) in the spark ignition engines. Blending of hydrogen in CNG improves the burning velocity and calorific value of CNG. Engine tests were carried out using CNG and optimized fuel blend of 18%HCNG for comparing the engine performance and emissions behavior. Marginal improvement in engine performance (up to 2%) and significant reduction in emissions with18%HCNG compared to neat CNG. The brake specific fuel consumption was 5% lesser compared to CNG. Replacement of methane by hydrogen in the 18%HCNG blend reduced the HC emissions by ~20% and NOx emissions was increased by ~ 10-20% compared to CNG. 18% HCNG decreased the methane emissions up to 25% compared to CNG. The investigation showed that 18% HCNG has given better performance and emissions compared to CNG.

  • Characterisation of Gasoline Fuels in a DISI Engine
    Characterisation of Gasoline Fuels in a DISI Engine Jon Pilbeam David Weissenberger Afton Chemical, Bracknell, UK SGS S.A., Vienna, Austria Whitepaper 1 Summary The importance of direct injection for gasoline has been described and demonstrated on numerous occasions in many articles and technical papers. Similarly, the impact of deposits forming on the injector and the subsequent effect on efficiency and emissions is also well documented and many oil and fuel additive companies have developed their own methodologies. However, until now there has not been an industry test available to compare deposit forming tendencies of different fuels or deposit control additives to clean them up. This paper looks at a recently proposed CEC direct injection gasoline fuels test based on the VW 1.4 ‘twin-charger’ engine. SGS laboratories secured access to a surrogate engine sharing most of the key hardware and software components common with that proposed for the CEC test. This allowed early work to be conducted between SGS and Afton Chemical to study a range of engine, fuel and deposit control additive effects. The impact of fuel properties on injector deposit formation was found to be significant. Previous studies have shown there is almost no consensus of ‘bad actors’ with regard to fuel properties and deposit formation. This seems likely to be due to the fact that each engine and test cycle has its own specific characteristics, and in this regard, this proposed CEC test currently appears to be no different. 2018 © Afton Chemical Corporation, All Rights Reserved.

  • Hydrogen Enriched Compressed Natural Gas (Hcng) – a Futuristic Fuel for Internal Combustion Engines
    HYDROGEN ENRICHED COMPRESSED NATURAL GAS (HCNG) – A FUTURISTIC FUEL FOR INTERNAL COMBUSTION ENGINES by Kasianantham NANTHAGOPAL a*, Rayapati SUBBARAO b, Thangavelu ELANGO a, Ponnusamy BASKAR a and Kandasamy ANNAMALAI c a Automotive Research Centre, SMBS,VIT University, Vellore-14, Tamilnadu, India, e-mail: [email protected] b Department of Mechanical Engineering , Indian Institute of Technology Madras, Chennai-25, India. c Department of Automobile Engineering , MIT Campus, Anna University, Chennai-25, India Air pollution is fast becoming a serious global problem with increasing population and its subsequent demands. This has resulted in increased usage of hydrogen as fuel for internal combustion engines. Hydrogen resources are vast and it is considered as one of the most promising fuel for automotive sector. As the required hydrogen infrastructure and refueling stations are not meeting the demand, widespread introduction of hydrogen vehicles is not possible in the near future. One of the solutions for this hurdle is to blend hydrogen with methane. Such types of blends take benefit of the unique combustion properties of hydrogen and at the same time reduce the demand for pure hydrogen. Enriching natural gas with hydrogen could be a potential alternative to common hydrocarbon fuels for internal combustion engine applications. Many researchers are working on this for the last few years and work is now focused on how to use this kind of fuel to its maximum extent. This technical note is an assessment of HCNG usage in case of internal combustion engines. Several examples and their salient features have been discussed. Finally, overall effects of hydrogen addition on an engine fueled with HCNG under various conditions are illustrated.
