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, ...

Early September 2011 two 40-ton Archimedes hydropower screw turbines were transported from Sneek, The Netherlands to the royal Windsor Castle, UK. Both screws are installed at Romney weir on the River Thames and power both the Royal Castle as well as 400 - 500 local households. The Landy screws dimension 4 meter diameter, 6 meter long and capacity 150 kW. Unique feature of each ...

It is believed that the power sector, particularly hydroelectric power, contributes to a very high consumption of fresh water in terms of evaporation from storage reservoirs. Robust methods of water footprint (WFP) assessment will eventually help in the pricing of water and energy. Conventionally, WFP for hydropower plants is estimated by dividing the gross/net evaporation losses by power ...

A first-order one-variable grey model (GM(1,1)) is combined with improved seasonal index (ISI) to forecast monthly energy production for small hydropower plants (SHPs) in an ungauged basin, in which the ISI is used to weaken the seasonality of input data for the GM(1,1) model. The ISI is calculated by a hybrid model combining K-means clustering technique and ratio-to-moving-average method, ...

Classical methods have severe limitations (such as being trapped in local optima, and the curse of dimensionality) to solve optimization problems. Evolutionary or meta-heuristic algorithms are currently favored as the tools of choice for tackling such complex non-linear reservoir operations. This paper evaluates the performance of an extended multi-objective developed firefly algorithm ...

As more and more reservoirs are built, concentrated water releasing in the dry season will bring about additional flow compensation and the joint operation of cascade hydro plants is quite important. This paper discusses the water level decline strategy of four cascade hydro plants in the Jinsha River and analyses the relationship between guaranteed output and total power generation. ...

Ocean Thermal Energy (OTE) Corporation may be landlocked in Lancaster, Pennsylvania, but that isn’t stopping them from looking to the ocean for 24/7 electricity. Their primary technology is Ocean Thermal Energy Conversion (OTEC), which uses the temperature differentials in the ocean to produce steam. The steam, in turn, activates a turbine, which generates clean energy and potable water. ...

Turkey's recent venture involving the construction of hundreds of small-scale hydropower projects is a significant trend, both in regard to its contribution to Turkey's hydroelectricity production and the social and environmental impact of these projects at the local level. Turkey's hydropower policy was premised on a conventional understanding of water driven by science, technology, and the ...

On 19 September 1960, the Indus Water Treaty (IWT) was signed between India and Pakistan, presumably resolving the conflict of Indus water sharing. Nevertheless, over the years the conflict has re-appeared, dragging both the riparian states into confrontation. This paper explores the reasons that lead to conflict despite the Indus water sharing having already been resolved by the IWT. Analysis ...
