2014 JRC Ocean Energy Status Report

by European Commission, Joint Research Centre  (May 11, 2015)

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 ...

DESMI Lifts Green Ship Business Case

by DESMI A/S  (Apr. 30, 2015)

New rules call for fresh approach It’s hardly news that the shipping industry is mobilising to meet the demands of wave after wave of new environmental regulations. From the IMO’s ballast water management legislation to EEDI (the Energy Efficiency Design Index for new ships) and SEEMP (Ship Energy Efficiency Management Plan), ...

Summertime conditions of a muddy estuarine environment: the EsCoSed project contribution

by IWA Publishing  (May 18, 2015)

As part of the Estuarine Cohesive Sediments (EsCoSed) project, a field experiment was performed in a highly engineered environment, acting as a natural laboratory, to study the physico-chemical properties of estuarine sediments and the associated hydro-morphodynamics during different seasons. The present contribution focuses on the results ...

Renewable, local power options expand

by Triplepundit  (May 15, 2015)

It makes no economic sense to run more than one set of wires from electric power generators to homes and businesses. That’s why consumers haven’t had a choice about the source of their electric power – whether it be an investor-owned utility (IOU), municipal utility or electric cooperative. Enabling consumers to choose between ...

Soil erosion in the riparian zone of the Three Gorges Reservoir, China

by IWA Publishing  (Mar. 19, 2015)

The riparian zone of the Three Gorges Reservoir (TGR) has experienced substantial erosion that may severely deteriorate the reservoir ecosystem. To calculate soil erosion characteristics, field investigations have been conducted in the TGR area and 12 erosion-monitoring transects have been set in the middle TGR. The results showed that the ...

Study on hydrodynamics and heat transfer of solitary wave on film flow with CFD method

by Inderscience Publishers  (Mar. 6, 2015)

In this paper, a capacitance probe and high speed camera are adopted to study the solitary wave of falling film on large flat plate experimentally. Two types of solitary wave are studied with a Computational Fluid Dynamic (CFD) method based on the measuring data. The water–air shear stress on the interface of the solitary wave is modelled in the ...

Earthy, solaris and atmospheric energy sources

by Inderscience Publishers  (Feb. 19, 2015)

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 ...

“We continue to be stunned at how rapidly the ocean is warming.”

by Ensia  (Jan. 29, 2015)

Oceans have been absorbing more of global warming’s heat and energy than would normally be expected, helping to slow rates of warming on land. But how long will that last? Probing a blue abyss can be an abysmal recipe for the blues. For every 10 joules of energy that our greenhouse gas pollution traps here on Earth, about 9 of them end up ...

National Grid Alert Triggers Wave of Enquiries for Renewables Sector

UrbanWind today reported a sharp increase in companies enquiring about on-site power generation, following National Grid’s warning yesterday.   It said growing numbers of British businesses were now looking to move towards ‘energy independence’ to protect themselves from the rising threat of future brownouts. ...
