  • SGBI opinion article: shale gas

    Government perceives electric vehicles to be a panacea that will solve problems surrounding air quality and CO2 emissions simultaneously. The EV has two main selling points: reduced CO2 emissions and high efficiency. However, these are only valid at a superficial level and the argument disintegrates under any level of scrutiny. In terms of CO2 emissions, EVs replace ‘average’ cars to ...

  • The natural gas revolution: Good or bad for energy efficiency?

    If there were an equivalent in the energy industry to Time Magazine’s Person of the Year, natural gas would be this year’s winner. The dramatic rise in natural gas supply, and fall in price, has reconfigured the energy scene in the United States, suddenly creating a bounty of domestic energy, driving down wholesale power prices and speeding retirement of polluting coal-fired plants. ...

  • Development of Pre-Turbo Catalyst for Natural Gas Engines

    Distributed power generation is an efficient method for reducing CO2 emissions through the elimination of transmission losses. Co-generation has similar benefits with higher thermal efficiency. Natural gas engines are very popular for these applications. Unfortunately, these engines emit significant levels of methane, ...

  • The effect of precooling inlet air on CHP efficiency in natural gas pressure reduction stations

    Almost all pressure reduction stations in Iran use expansion valves to reduce the natural gas pressure, which leads to wasting large amount of exergy. In this paper, a system is proposed which includes the modification of a conventional pressure reduction station with the addition of a turbo expander and a gas turbine for power recovery and generation. The next step is investigating the effect of ...

  • Water impounded bottom ash collection systems

    Ash is a by-product of the combustion process in power generating stations that burn coal as a primary fuel. Combustion takes place in a boiler that is actually a large open furnace. The walls of the furnace are lined with pipes that carry water to produce steam that powers a turbine generator. Ash is present in two forms: 1) Fly-ash, a lighter material that exits the boiler in the flue-gas ...

  • Exergoeconomic optimisation of steam power plant

    The second law of thermodynamics combined with economics forms a powerful tool for systematic analysis and assessment of energy systems. This paper presents an exergoeconomic optimisation of 50 MW steam turbine power plant associated with a large fertiliser industrial unit through Thermoeconomic Evaluation and Optimisation (TEO) method, and identifies the losses in various components. As the ...

  • Pushing the Limits of Reengineering

    Cutting-edge turbine technology enables more efficient and cleaner power generation. However, the service of advanced gas turbines is challenging—especially when parts need to be replaced. The example of a blade replacement project shows how Sulzer establishes innovative reengineering processes and contributes to a secure energy supply that causes less carbon emission. A Sulzer ...

  • MHR-T power-technological complex: safety aspects

    The paper deals with the safety assurance aspects of a power-technological complex for large-scale hydrogen production (MHR-T PTC) combining the innovative nuclear and hydrogen processes. It reviews practical realisation of the nuclear-hydrogen concept developed in early 1970s on the basis of high-temperature helium reactor plants of the fourth MHR-T generation, which allows production of ...

  • Notus Clean Energy LLC – Cape Cod, MA - Case Study

    The owners of a Falmouth, MA industrial park parcel saw the potential in 2004 for a utility-scale wind turbine sited in a large, well-elevated location. A large turbine could supply electricity for the complex and create surplus power that could be delivered back to a regional utility. Despite receiving more than 100 letters of support from residents and businesses, the proposal required five ...

  • Thermodynamic performance simulation of a coal gasification and SOFC based combined cogeneration plant by energy and exergy analyses

    This paper presents a thermodynamic model of a combined cogeneration plant that employs a coal gasifier, a gas cooler and a solid oxide fuel cell (SOFC) upstream of the gas turbine and a downstream HRSG to generate process steam at low pressure. Simulated performance of the plant with respect to variations in some design and operating parameters has been reported. While energy analysis indicates ...

  • What’s the Future of R&D in the Wind Industry?

    When the wind industry finally reacted to the world’s financial crisis—it didn’t fully hit us until 2010—at once, we lost both an incredibly vibrant global wind market and sufficiently robust profit margins. The market recovery is rebounding nicely now, thanks largely to government incentives, but profit margins will probably never fully recover—at least, not to the ...

  • Offshore wind installation vessel capacity to tighten after 2020

    The existing fleet of turbine and foundation installation vessels is well suited to serve the European offshore wind market in the short and mid-term but it will not be sufficient to support installation demand after 2020, Michael Guldbrandtsen, senior consultant at MAKE Consulting, told Wind Energy Update. The next 2-3 years will continue to be dominated by orders for jack-up ...

  • Mr. Pickens, what about plug-in hybrids?

    T. Boone Pickens deserves kudos for his attention-grabbing television campaign aimed at helping America kick the oil habit. The billionaire energy fund manager can stop the most dedicated channel surfer mid-click when he proclaims that our spending on foreign oil could soon become the largest transfer of wealth in human history.Pickens’ plan has two parts. The first calls for more use of wind ...

  • Biogas cleaning / conditioning - A requirement for optimal functioning of CHP systems

    Biogas is obtained through the anaerobic decomposition (putrefaction) of organic matter. It contains methane (CH4) in varying proportions, ranging from 35% to 70%, a proportion which largely depends on production methods and the materials involved in the process. This methane concentration is what enables biogas to be used as fuel. The release of methane into the atmosphere contributes to an ...
