Abstract In combination with other climate change mitigation options (renewable energy and energy efficiency), the implementation of CCS will be necessary to reach climate targets. If CCS is applied in with bioenergy processes (bio-CCS schemes), negative CO2 emissions can be potentially achieved. This study aims to provide an initial overview of the potential of biomass and waste gasification to contribute to carbon capture and sequestration (CCS) through the assessment of two example scenarios. The selected study cases (600 MWth thermal input) represent two different routes to biofuels production via gasification which cover a relevant range of gasification technologies, biofuel products and CCS infrastructure conditions: • Case 1: production of Fischer-Tropsch syncrude from high-temperature, entrained-flow gasification in Norway.

  • Turbine Subsystems Include
    What is wind energy? In reality, wind energy is a converted form of solar energy. The sun's radiation heats different parts of the earth at different rates-most notably during the day and night, but also when different surfaces (for example, water and land) absorb or reflect at different rates. This in turn causes portions of the atmosphere to warm differently. Hot air rises, reducing the atmospheric pressure at the earth's surface, and cooler air is drawn in to replace it. The result is wind. Air has mass, and when it is in motion, it contains the energy of that motion("kinetic energy"). Some portion of that energy can converted into other forms mechanical force or electricity that we can use to perform work. What is a wind turbine and how does it work? A wind energy system transforms the kinetic energy of the wind into mechanical or electrical energy that can be harnessed for practical use. Mechanical energy is most commonly used for pumping water in rural or remote locations- the "farm windmill" still seen in many rural areas of the U.S. is a mechanical wind pumper - but it can also be used for many other purposes (grinding grain, sawing, pushing a sailboat, etc.). Wind electric turbines generate electricity for homes and businesses and for sale to utilities. There are two basic designs of wind electric turbines: vertical-axis, or "egg-beater" style, and horizontal-axis (propeller-style) machines. Horizontal-axis wind turbines are most common today, constituting nearly all of the "utility-scale" (100 kilowatts, kW, capacity and larger) turbines in the global market.

  • Technical and Economic Aspects of Load Following with Nuclear Power Plants
    Nuclear Development June 2011 www.oecd-nea.org Technical and Economic Aspects of Load Following with Nuclear Power Plants NUCLEAR ENERGY AGENCY Nuclear Development Technical and Economic Aspects of Load Following with Nuclear Power Plants © OECD 2011 NUCLEAR ENERGY AGENCY ORGANISATION FOR ECONOMIC CO-OPERATION AND DEVELOPMENT Foreword Nuclear power plants are used extensively as base load sources of electricity. This is the most economical and technically simple mode of operation. In this mode, power changes are limited to frequency regulation for grid stability purposes and shutdowns for safety purposes. However for countries with high nuclear shares or desiring to significantly increase renewable energy sources, the question arises as to the ability of nuclear power plants to follow load on a regular basis, including daily variations of the power demand. This report considers the capability of nuclear power plants to follow load and the associated issues that arise when operating in a load following mode. The report was initiated as part of the NEA study “System effects of nuclear power”. It provided a detailed analysis of the technical and economic aspects of load-following with nuclear power plants, and summarises the impact of load-following on the operational mode, fuel performance and ageing of large equipment components of the plant. 3 Acknowledgements Valuable comments and contributions were received from Mr. Philippe Lebreton, Electricité de France, Dr. Holger Ludwig, Areva GMBH, Dr. Michael Micklinghoff, E.ON Kernkraft and Dr. M.A.Podshibyakin, OKB “GIDROPRESS”.
