  • 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 ...

  • Ocean Thermal Energy conversion and the company bringing it to market: peace for our children

    Two centuries ago, U.S. President John Adams advised us of the importance of observing our world with clear eyes, “Facts are stubborn things; and whatever may be our wishes and passions, they cannot alter the state of facts and evidence.” Though there are some facts we all would rather not face, one of those unpleasant truths is that there are places in the world where the need for ...

  • 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 ...

  • A binary ACO for controlling all–electric power take off system in wave energy converters

    This paper describes a metaheuristic algorithm for controlling all–electric power take off (PTO) system of wave energy converters. It provides optimal parameter values to the controller following the instantaneously changing sea state. The output of the algorithm is used to tune the electrical control systems in the PTO system in order to provide sufficient time for the point absorber to achieve ...

  • 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 ...

  • 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 ...

  • Introduction to Solar Energy

    Solar energy refers to solar radiation energy. Since the formation of the earth, organism relies on the light and heat provide by the sun to survive. But nowadays, the application of solar energy has been widely paid attentions. In recent years, an increasing numbers of people pay more attention to it not because of its characteristics of the inexhaustible, but also ...

  • 2014 JRC Ocean Energy Status Report

    Abstract Oceans and seas have the potential to play a significant role in providing clean energy. Different technologies are currently being developed to ensure a long term contribution of ocean energy to the future energy system. Among the different ocean energy technologies, tidal and wave conversion systems are expected to contribute the most to the European energy system in the short ...

  • Ocean Thermal Energy and Water Production

    Introduction The scarcity of potable water is a growing problem worldwide, particularly in arid regions and among developing countries. Compounding this problem is the increasing contamination of freshwater sources, which comprise only about 2.5% of all water on Earth. Of this small portion, only 0.5% of the total fresh water available is found in easily accessible sources such as ...

  • Renewable energy from the ocean and tides: A viable renewable energy resource in search of a suitable regulatory framework

    Ocean energy technology involves a range of engineering technologies that are able to obtain energy from the ocean using a variety of conversion mechanisms. Over the past few years there has been significant progress towards the development of commercial scale operations of ocean energy, especially hydrokinetic energy (where the energy of ocean (or fluvial) currents and tides is captured by ...

  • Interview with Adam Penque, Lockheed Martin Energy

    Tell us more about how and why Lockheed Martin Energy is building its position in the Waste to Energy sector. As the world population swells to more than seven billion and counting, the need for sustainable waste disposal and clean energy generation is growing with it. Lockheed Martin’s bioenergy power generation systems have the potential to solve both challenges At its ...

  • Power control strategy for grid connected permanent magnet synchronous generator of a distributed generation unit

    This paper describes the studies on the operation and control of a variable speed wave energy conversion system. The wave energy conversion system considered is oscillating–water–column (OWC) based Wells turbine driven permanent magnet synchronous generator connected to the grid by means of fully controlled frequency converter. In such systems primary aim is to achieve a low distortion, high ...

  • Contrasting suspended covers reveal the impact of an artificial monolayer on heat transfer processes at the interfacial boundary layer

    The highly variable performance of artificial monolayers in reducing evaporation from water storages has been attributed to wind speed and wave turbulence. Other factors operating at the interfacial boundary layer have seldom been considered. In this paper, two physical shade covers differing in porosity and reflectivity were suspended over 10 m diameter water tanks to attenuate wind and wave ...

  • Reaching underground resources

    Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...

  • Recapping the Debate Over Whether Low-Carbon Economies Are Good for Tech

    To be of any use, tech products need power from electrical outlets, stored chemical energy such as batteries and generators, solar collectors, kinetic energy like my emergency hand-crank radio/charger, or other means. As more global and local regions move away from fossil-fuel-based power to low-carbon renewable power, I wonder how my colleagues in the tech industry would weigh in on a debate ...

  • How mangroves help in reducing flooding and coastal erosion

    Inhabitants of low lying delta areas are particularly exposed to flooding and erosion caused by storms and hurricanes. These pressures increase with climate change and sea level rise. Coastal wetlands, such as mangroves, can play a key role in damage mitigation during disasters, as well as in stabilising coastlines. They also contribute to aquaculture and fisheries. Integration of ecosystem-based ...

  • Zero emissions day: What it is and why we need it

    Today is September the 21st – a day that didn’t hold any particular significance until a simple observation occurred in the 1980’s. Ken Wallace, father of a newborn daughter, realized, after witnessing the local neighborhood pizzeria truck, parked, running and driverless, combined with the surrounding traffic that “Stopping all this for a bit would be most excellent for ...

  • Copenhagen aspires to be the first carbon neutral capital in the world

    The City Council of Copenhagen is aiming to make the capital carbon neutral by 2025 – the first capital city in the world to do so. CO2 emissions have already been reduced by 21 % since 2005. On the 23rd of August, 2012, it is expected that a majority of votes at the Copenhagen City Council will pass the CPH 2025 Climate Plan with the ambition of carbon neutrality by 2025. ...
