Lyme Bay project to pioneer new partnership - Fishupdate.com

With the Government currently debating the designation of up to 127 similar zones, this project could represent a new milestone in efforts to manage the UK’s inshore waters, representing the first example of self-regulation by local fishermen and promising to create a model with potential to be applied across other threatened coastal areas.

Creating the next generation power stations

In pressure-retarded osmosis, seawater and fresh water are separated by a semi-permeable membrane which allows the passage of water but prevents that of salt ions. (Photo: Morguefile) Osmotic power generation is a renewable energy source which results in no pollution of the atmosphere and only moderate emissions to the sea. Globally, the energy generating potential of osmotic generation is estimated at around 1,650 TWh, which corresponds to around 12 times Norway’s annual energy production. “The energy source is also predictable, compared with wind, wave, tidal and solar generation,” says Edvard Sivertsen, project manager in SINTEF Building and Infrastructure.

June 20, 2012 — he rise of ocean infrastructure development to tap energy sources such as tides, offshore wind and natural gas will require more pile driving, the practice of pounding long, hollow steel pipes called piles into the ocean floor to support energy turbines and other structures. But pile driving creates loud, underwater booms that can harm fish and other marine animals. Many scientists and regulators have assumed that limiting the combined amount of sound created during the course of a pile driving project can minimize harm to animals.

Turning down the dial: Ocean energy development with less sound

June 26, 2012 — The energy generated from our oceans could be doubled using new methods for predicting wave power. Research led by the University of Exeter, published (27 June) in the journal Renewable Energy , could pave the way for significant advancements in marine renewable energy, making it a more viable source of power.
