  • Simulation-based evaluation of tidal current power output characteristics

    Tidal current is considered to be one of the promising alternative green energy resources. This paper introduces a simulation based methodology to evaluate tidal current power output characteristics, including capacity factor, and power production variability patterns. Power variability analysis is crucial to grid integration systems design. The proposed methodology is applied to the well known ...

  • A Review of Cavitation-Erosion Resistant Weld Surfacing Alloys for Hydroturbines

    AbstractAn improved weld surfacing alloy has been developed and tested to resist cavitation-erosion in hydroturbines. Typical wear characteristics experienced in laboratory testing has been correlated to actual service conditions. A metallurgical evaluation shows that a high strain, work hardening austenitic stainless steel produces superior resistance to cavitational erosion. Several industrial ...

  • Key issues of tidal energy and factors affecting it globally with civil structures

    This paper focus on some of the key challenges to be met in the development of marine energy, it present prototype form to being a widely deployed contributor to future energy supply of the world. Large-scale wave and tidal current prototypes have been demonstrated around the world, but marine renewable energy technology is still 10-15 years behind that of wind energy. However, having started ...

  • DOE provides more renewables funding

    The U.S. Department of Energy (DOE) announced on September 16 that it will provide nearly $100 million for renewable energy research, including $16.5 million for biomass energy, $30 million for state energy efficiency projects, and $9.6 million for “transformational” energy research, such as airborne wind turbines and solar photovoltaic (PV) systems with non-mechanical ...

  • Oceans of Energy

    Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...

  • A novel FACTS dynamic stabilisation scheme for stand-alone tidal energy conversion systems

    Renewable abundant ocean kinetic energy has become increasingly popular as a consequence of strong ecological viable concerns and economical energy solutions in remote island communities. However, the integration of dispersed renewable tidal energy will pose a greater challenge to the power quality of distribution networks in remote areas due to fluctuation of the tidal stream velocity. The paper ...

  • Research and development in ocean energy technologies

    The volatile fuel prices for electricity generation, elevated concerns about global warming and energy security has prompted countries to look for alternative energy sources. One of the alternative energy sources is ocean energy. Currently, there is few ocean energy technologies that are commercially available to harness electrical energy from ocean despite the fact that ocean covers more than ...

  • Gamesa, Northrop Grumman to collaborate in offshore wind

    Spanish wind technology giant Gamesa and U.S. defense contractor Northrop Grumman (Los Angeles, CA) have signed an agreement under which the two companies will collaborate in the development of technologies for offshore wind facilities. Under the terms of the agreement, Northrop Grumman Shipbuilding will apply its experience in heavy load logistics, systems performance, and reliability ...

  • Environmental impacts of ocean-energy systems: a life-cycle assessment

    Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the ...

  • Innovation risk slows offshore wind foundation development

    As offshore wind technology develops ever more gigantic machines further from shore into deeper waters, it is common wisdom that new foundation technologies are needed. But are they? Monopile, and some jacket foundations, still dominate the offshore wind market in commercial operation. Prototype floating foundations are performing well in demo or pilot projects, but scaling up is only ...

  • Wind & solar energy and nature conservation

    Climate change and the degradation of ecosystems and biodiversity cannot be solved in isolation. Land and marine ecosystems play a crucial role in the climate system, capturing roughly half of carbon dioxide emissions generated by human activities (UNEP, 2009). Protecting biodiversity preserves ecosystem services that are important for regulating the climate and helping us to adapt to the impacts ...

  • Offshore Wind Development Picking Up Pace

    Wind power is the world’s leading source of renewable electricity, excluding hydropower, with 238,000 megawatts of capacity installed at the start of 2012. Thus far, almost all of this wind power has been tapped on land; worldwide just 4,600 megawatts of offshore wind farms were operating as of mid-2012. Offshore wind capacity is growing quickly, however, expanding nearly six-fold ...

  • Efficiency beyond pizza money: The military’s gigantic bite

    Is efficiency worth the bother if you save only $5-$10 per month on your energy bill? Many homeowners think not. One dad told us his family would rather save money by just skipping a pizza order once a month. That sentiment is not unusual.   But it is hard to negate the economic value of efficiency if you spend $20 billion per year on energy, as does ...
