Supporting wave and tidal energy in the UK - an analysis of UK Policy 2000-2009
In order to stimulate UK based marine energy technology developers, the UK Government launched the Marine Renewables Proving Fund (MRPF) in 2009. This instrument was designed to bridge the gap between early-stage research funding and the recently-criticised Marine Renewables Deployment Fund (MRDF). This paper develops an analysis framework for policy instruments designed to support technology ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Critical review of energy options
Short term measure for dealing with energy crisis is reducing consumption by: 1) improving the efficiency of all energy consuming machines; 2) eliminating the wasteful use of energy. Renewable sources of energy such as solar, wind, tidal, waves, etc., do make a significant contribution to demand for energy but they are unlikely to meet the ever increasing consumption. Long term measures may ...

A novel particle swarm optimisation self-regulating stand-alone wave energy conversion scheme
The paper presents a novel stabilisation scheme system for a wave energy converter (WEC) using permanent magnet linear generator (PMLG) connected to a six-pulse diode rectifier. The proposed controller of WEC-battery renewable energy system is based on multi-objective particle swarm optimisation (MOPSO) technique. The optimisation algorithm is implemented to control a novel low cost dynamic AC ...

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 ...

Green Energy Fuel by Briquettes Machine
Now a day’s demand of energy is increasing very rapidly but we have the limited sources to satisfy the energy requirements. This energy demand is expected to grow almost by half over in the next two decades. So it is causing fear that our resources will run out by future. This will lead to shocking consequences of global economy. On the other side, Due to the emission of carbon dioxide ...

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 ...

Introduction to some kinds of renewable energy
Clean energy is a kind of energy which does not produce pollutants in the use procedure. It includes nuclear energy and "renewable energy". Renewable energy refers to a kind of inexhaustible energy such as hydropower, wind power, solar energy, biomass energy (biogas), water energy, and tidal energy and so on. Renewable energy doesn’t have the possibility of energy depletion, and ...

Why do Renewable Energy Meters appear?
What is renewable energy? What is the defining of Renewable Energy Meter? Renewable energy is natually avilable and can be recycle without human intervention, which is an inexhaustible source of energy. Wind energy, water energy, solar energy, tidal energy, geothermal energy are compliance with renewable energy standards. With the trend of warmed the Earth, most of countries have agreed that will ...

Harnessing marine renewable energy from Poole Harbour: a case study
Global warming and its impact on our environment, society and economy is one of the fundamental concerns of our time. In response, the UK Government has implemented numerous targets including the 80% reduction in greenhouse gas emissions on 1990 levels by 2050, and the increase of renewable energy to 15% by 2020. In order to contribute towards these targets, the government may seek to harness ...
