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 ...

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 ...

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 ...

The Economic Tide of this Renewable Resource is Rising
In the early 1970s, various types of wave energy converters were proposed as concerns surrounding the 1973 oil crisis began to rise. Since then, R&D of wave energy has been growing as more and more investors and engineers have acknowledged the resource’s environmental and economic benefits. According to a 2020 Market Research Report, the global wave energy market is projected to reach ...

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 ...
