ENERGETECH WAVE ENERGY SUCCESS
On Wednesday 26 October, Energetech Australia successfully demonstrated
the capacity of its patented wave energy conversion technology at
its test site in Port Kembla, New South Wales.
With independent observers on board, Energetech’s wave energy barge
(WEB) was towed out beyond the Port Kembla breakwater.
During periods of significant wave activity, the WEB, which was
christened “Uisce Beatha” (meaning, appropriately, “Water of Life” in
Gaelic), performed beyond expectations, according to Energetech
Project Director, Emil de Graaff.
Over the test period, Energetech’s patented Denniss-Auld Turbine
generated power, despite the fact that the floating configuration
was not optimised (during this particular test) for maximum wave
heights. This power was then used to generate electricity via the
on-board generator and produce fresh water via the on-board
desalination plant. The water samples collected are being
independently verified against local water standards.
This is the first time in the world that a floating water column has
successfully generated power, and also a world first in the use
of a turbine with rotating blades.
Tom Engelsman, CEO of Energetech, who was on board Uisce Beatha for the
trial, said, “We are delighted with the results of today’s
trial which validated all aspects of our technology, even in a
preliminary deployment. We are planning a longer operating period
but we now have sufficient data to move on to commercial projects
both in Australia and around the world.”
“I would also like to sincerely thank Dr Ray Alcorn and the engineering
team, and Emil de Graaff, our Port Kembla Project Director for
their enthusiasm, hard work and dedication in achieving this
result, and congratulate Tom Denniss, the inventor of the turbine, on
the realisation of his vision,” he added.
Energetech is a renewable energy technology development and industry
advisory company. The company has developed a new and
commercially efficient system for extracting energy from ocean waves
and converting it to electricity or desalinated water. The
Energetech technology now makes it possible for wave energy to provide
a cheap, sustainable source of power or water to gridconnected and
What device will be installed
at the Port Kembla Site and how will it work?
Energetech has worked
collaboratively with JP Kenny Pty Ltd to successfully design a
moored structure made of structural steel. The device and accompanying
structure is designed to withstand a 1 in 100 year storm.
In brief, the system employs a
parabolic wall to focus wave energy on to an Oscillating Water Column
(OWC) chamber. The rising and falling motion of the waves causes an
oscillatory water motion within the chamber, which in turn forces a
high-speed airflow past a unique controllable turbine. The turbine
drives an induction generator to produce electrical power. System
components are computer controlled to optimize energy conversion in a
range of conditions and to automatically protect system components and

desalination unit. This unit will
produce nearly 2000 litres of fresh drinkable water per day using
nothing but water and power directly from the ocean itself.

be a world first, and will demonstrate what is expected to become a
very important component of the technology. Wave energy is considered
to have the potential to eventually supply a meaningful proportion of
the world's fresh water.
Ocean Waves Offer Sustainable Solution to Looming Water Crisis
A unique low-energy water
desalination solution has been developed by
two innovative Australian companies working in cooperation - Energetech
Australia Pty Limited (Energetech) and H2AU Pty Limited (H2AU).
Water has long been determined as
a critical resource for any society
and, due to the recent concerns with regard to global climate changes,
as well as overall energy costs and greenhouse emissions, this global
concern has become a major policy issue. The changing rainfall patterns
have left many catchment areas in Australia bereft of the necessary
water levels to sustain demand, and water restrictions have become a
serious problem in many areas of the country.
Energetech has developed and
demonstrated a patented process to extract commercially viable
energy from the ocean waves, and operates a full scale unit in Port
Kembla, Wollongong. This unit generates electrical power which can be
supplied to the local community grid, but also has a small reverse
osmosis unit to make fresh water from the same clean wave energy.
H2AU is a leading systems integrator for modular reverse osmosis units,
and has been very successful with the supply of such systems for ocean
liners and other commercial applications. The H2AU Managing Director,
Mr. David Murdoch, said that the current work with Energetech is
“an exciting extension of this well known technology, and can certainly
have direct application in Australia and around the world. Desalination
of this type is very cost competitive, and with the low cost/zero
emission wave energy source as the supply, we are very confident that
this will open up many opportunities” he added.
A single unit
of this type would be able to produce approximately 3 million
litres of fresh water per day, and do so without generating any
emissions. With the ability to cluster units offshore, the water
needs of cities or industries can be met without having to use valuable
sea shore real estate as in the case of land based desalination plants,
whilst brine dispersal is much less of an issue at sea.
