Tidal power - A different perspective
Kepler Energy is taking a different approach to tidal power, applying a design that can be used in benign sea conditions in a location closer to end-demand and which could generate utility-scale quantities of power, as Peter Dixon explains.The physical environment of tidal turbines is clearly very different to that of wind turbines, not least because water is a lot denser than air! However, ...

Marine energy innovation in the UK energy system: financial capital, social capital and interactive learning
Innovation activity in marine energy (wave and tidal stream) has been catalysed by a series of recent UK policy initiatives. However, the wider UK energy system remains substantially oriented to market competition and efficiency. As a result, tensions have emerged between recent R&D activity (especially interactive and collaborative learning) and its economic and institutional context. Drawing on ...

Ocean exergy and energy conversion systems
Oceans store energy in the form of currents, waves, tides, heat and salinity that can help to alleviate worldwide demand for power and the global climate change threat. They also store a considerable amount of an isotope of hydrogen (deuterium) which takes part in the most promising fusion reactions. Exergy analysis can be applied to evaluate the work potential (extractable) of a resource. This ...

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 ...

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 ...

GWT - Environmental Interview - Water Technologies 2012 and beyond
Water is the most abundant resource on this planet, covering 70.9% of the earth’s surface. Yet, water is also our most precious resource, not just for hydration and nourishment, but also for the air we breathe. Only 2.5% of all the water on earth is fresh, and of that nearly 99% is in ice and groundwater. The very small remaining fraction is what supports most of the human and animal ...

An optimal energy allocation model using fuzzy linear programming for energy planning in India for the year 2020
Development of an energy allocation model will help in the proper allocation of the energy sources in meeting the future energy demand in India. In this paper, an attempt has been made to develop a fuzzy-based linear programming optimal energy model that minimises the cost and determines the optimum allocation of different energy sources for the centralised and decentralised power generation in ...

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 ...

Fission, Fusion, What's the Confusion?
Clean, sustainable, and renewable energy is a hot topic. Our world runs on energy and our production and use of energy shouldn’t put us or future generations in harm’s way. Society has responded to increasing power demands with technology such as nuclear fission. Fission splits uranium into smaller elements and releases large amounts of energy used to heat water in nuclear reactors ...

Data Highlight: Hydropower Continues Steady Growth
World hydroelectric power generation has risen steadily by an average 3 percent annually since 1965. In 2011, at 3,500 billion kilowatt-hours, hydroelectricity accounted for roughly 16 percent of global electricity generation, almost all produced by the world’s 45,000-plus large dams. Graph on World Hydroelectric Generation, 1965-2011 Four countries dominate the hydropower landscape: ...

Is marine energy about to go mainstream?
Why the costs of wave and tidal power could soon plummet - viewpoint from Dr Stephen Wyatt, Head of Technology Acceleration, Carbon Trust As the marine industry gathers in London for its annual get together one thing is clear; the sector is growing up fast. So fast that it looks like it will soon be defying its critics and getting its feet seriously wet after many years of tests, tanks and ...

EC support for UK power link raises Ireland’s offshore export potential
The European Commission (EC) announced November 18 it had given priority status to ISLES, a cluster of Irish Sea grid projects which would transmit power from proposed Irish offshore wind farms to the UK grid. There are currently five Irish offshore windfarm projects for a total 2.6 GW of capacity. The inclusion of ISLES in the EC’s list of “projects of common interest” allows ...

Earthy, solaris and atmospheric energy sources
Earth, sun and atmosphere are the ultimate energy resources. In addition to fossil fuels, earth radiates over 45 TW geothermal energy. Sun radiates about 89 PW energy to earth's surface. Lunar gravity supplies over 100 GW tidal ocean energy. Accessible energy from geothermal, solar, tides, waves and winds is far more than our current 17 TW energy demand, yet there are new avenues like tornadoes ...

Renewable energy progress report
What is the Renewable energy progress report and what is its purpose? The Renewable Energy Directive states that a progress report should be issued every two years. The purpose of this progress report is to assess Member States' progress in the promotion and use of renewable energy in line with the 2020 targets. In addition, it contains sections on thesustainability scheme for biofuels and ...

European Power Markets in Transition
With European energy markets in transition, all market participants now face a number of potentially tricky challenges. A combination of EU initiatives, increasingly invasive regulations and a backdrop of falling and less volatile commodity prices, have precipitated an era of change and uncertainty in which there are fewer trading opportunities and profits are harder to come by. Analysis of the ...
