Several
questions have be emailed to Hales Water Turbines Ltd regarding the last Blog
Post.
The first of several was the
following :-
What is the
potential amounts of tidal energy contained within the territorial waters of
each country within the continental shelf, if low-velocity tidal areas were
fully exploited to reduced the effects of Climate Change ?.
First of all,
lets assume that no restrictions to each national territorial waters are in
place, then very large areas, thousands of square kilometres are with tidal
flows of 1.0 m/s or more. With the use
of suitable venturi acting systems, which basically are just a method of
funnelling the water flows with a narrower entry mouth of the turbines which
greatly increases the energy potential to extract, also the venturi areas can
act as marine nurseries for most species in that area.
Most
low-velocity reaction type tidal
turbines have a vertical output shaft so modular construction into a tidal
fence energy farm, these could also be linked up with off-shore wind turbines and wave generators and the
renewable energy sent to shore through a common cable. In future years these
Marine Energy farms will be set to produce Hydrogen and again piped ashore.
Under these
conditions,
Both the UK
and Republic of Ireland could supply 100% plus of national grid requirements.
France approx
80%, Belgium and Holland 75 - 80%, Germany 60% , Norway 75 %, Denmark 85 -90 % Portugal
60%, Spain 45%.
Spatial information
on all water velocities and depths within the European continental shelf area are held by national naval and marine
departments and much can also be found on the internet.
