Environmental impacts of ocean-energy systems: a life-cycle assessment

by European Commission, Environment DG  (Sep. 23, 2016)

Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. ...

Modelling runoff on ceramic tile roofs using the kinematic wave equations

by IWA Publishing  (Mar. 15, 2016)

Generally, roofs are the best candidates for rainwater harvesting. In this context, the correct evaluation of the quantity and quality of runoff from roofs is essential to effectively design rainwater harvesting systems. This study aims to evaluate the performance of a kinematic wave based numerical model in simulating runoff on sloping roofs, ...

EC support for UK power link raises Ireland’s offshore export potential

by Wind Energy Update - part of the FC Business Intelligence Ltd group  (Dec. 1, 2015)

The European Commission (EC) announced November 18 it had given priority status to ISLES, a cluster of Irish Sea grid projects which would transmit power from proposed Irish offshore wind farms to the UK grid. There are currently five Irish offshore windfarm projects for a total 2.6 GW of capacity. The inclusion of ISLES in the EC’s list of ...

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 ...

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 ...

“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. ...

by Energy Institute (EI)  (Sep. 1, 2014)

Paul Harrison, Consultant to the HMC-4A Marine Oil Transportation Database Committee, presents latest findings from analysis of the 2013 data on marine crude oil transport. The Energy Institute (EI) HMC- 4A Marine Oil Transportation Database Committee has been collecting and analysing worldwide oil shipping data for over 20 years and meets twice ...

Oceans of Energy

by Ensia  (Mar. 10, 2014)

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 ...

Analytical solution of a kinematic wave approximation for channel routing

by IWA Publishing  (Feb. 12, 2014)

The kinematic wave approach is often used in hydrological models to describe channel and overland flow. The kinematic wave is suitable for situations where the local and convective acceleration, as well as the pressure term in the dynamic wave model is negligible with respect to the friction and body forces. This is the case when describing ...

Simulation of Subsurface Electromagnetic Wave Propagation and Scattering.

by Transient Technologies LLC  (Feb. 3, 2014)

A subsurface radar technique is used for a microwave non-invasive probing in opaque regions in soils, rocks, fresh water, brick, concrete etc. There is an inherent complexity of a subsurface radar survey some. Unavoidable features of a radar functioning, numerous wave propagation and scattering events complicate seriously a radar data processing ...
