CETO Project Update

Highlights:

* Outstanding results from initial 'in-sea' CETO II trials
* Onshore CETO test rig complete
* First complete CETO II pump on track for sea deployment within weeks

Renewable Energy Holdings plc (AIM: REH), the AIM quoted investor and operator
of proven and innovative renewable energy technologies, is pleased to announce
that initial in-sea trials carried out over the past three months off the coast
of Fremantle, Western Australia, have returned outstanding results.

Buoyant actuators were deployed with instrumentation attached in order to
measure the real forces attracted by CETO II units in varying wave conditions,
with the measured data relayed back to onshore computers. The real measured data
has now been compared to the data predicted by the CETO Computational Fluid
Dynamic ('CFD') models and the correlation is excellent.

The successful initial in-sea trials allow the first of the commercial design
CETO II pumps to be deployed off Fremantle in the coming weeks to recommence
power and water production. This will be closely followed by subsequent unit
deployment, with the aim of having a small array of CETO II units operating off
Fremantle by the end of 2007.

REH has also completed the construction of an onshore test rig which will allow
the testing of all pump units prior to ocean deployment, as well as providing
ongoing accelerated life cycle testing to confirm the reliability of the units
in parallel with in-sea trials.

In addition, REH will shortly begin deeper water, full-scale CETO III tests
which will allow in-sea testing of the final design parameters ahead of CETO's
commercial-scale deployment scheduled to begin in 2009.

Commenting on the test results, Mike Proffitt, Chief Executive of REH said:

'This is another major technical achievement on the development pathway to CETO
commercialization.

'The results of these in-sea trials validate the hard work and investment made
to date and confirm the potential of the commercial CETO II design. It also
clears the way for us to begin deploying the first of the complete CETO II units
off Fremantle within weeks.'

Background:

Following the successful proof of concept milestones of CETO I at Fremantle,
Western Australia in 2005, and the production of power and water in 2006, much
of the commercial CETO II design development has been carried out utilizing
complex Computational Fluid Dynamic ('CFD') modelling.

These models involved the development of a purpose-built virtual ocean that
requires sophisticated hardware and software. It allows an infinite number of
design parameters to be comprehensively tested at full-scale, in a virtual
environment and in a variety of ocean conditions. Such virtual tests preceded
the deployment of real physical CETO II prototypes in the ocean for in-sea
trials and allow design variables, such as the size, shape and buoyancy of the
buoyant actuator, along with material selection and pump dimensions to be tested
in differing wave height, sea and current combinations in this virtual ocean. An
image from the virtual wave tank and video footage is available at
www.ceto.com.au

Named after the Greek ocean goddess, the CETO system distinguishes itself from
other wave energy devices by operating out of sight and being anchored to the
ocean floor. An array of submerged buoys is tethered to seabed pump units. The
buoys move in harmony with the motion of the passing waves, driving the pumps
which in turn pressurize seawater which is delivered ashore via a pipeline. The
high-pressure seawater can then be used to supply a reverse osmosis desalination
plant, replacing greenhouse gas emitting pumps usually required for such plants.
The high-pressure seawater can also be used to drive hydro turbines, generating
zero-emission electricity.

Other wave energy and CETO characteristics include:

* Wave energy is a renewable, zero-emission source of power.
* 60% of the world lives within 60km of a coast, minimizing transmission
issues.
* As water is about 800 times denser than air, the energy density of
waves exceeds that of wind many times over, dramatically increasing
the amount of energy available for harvesting.
* Waves are predictable days in advance, making it easy to match supply
and demand (Wind is predictable hours in advance at best).
* CETO sits underwater, moored to the sea floor, meaning there is no
visual impact.
* CETO units operate in deep water, away from breaking waves. The waves
regenerate once they pass the CETO units, meaning there is no impact
on popular surfing sites.
* CETO units are designed to operate in harmony with the waves rather
than attempting to resist them. This means there is no need for
massive steel and concrete structures to be built.
* CETO is the only wave energy technology that produces fresh water
directly from seawater by magnifying the pressure variations in
ocean waves.
* Any combination of power and water can be achieved from 100% power
through to 100% water.
* CETO contains no oils, lubricants or offshore electrical components.
CETO is built from components with a known subsea life of over 30
years.
* CETO units act like artificial reefs in the way they attract marine
life.

Notes to Editors

About Renewable Energy Holdings

* Renewable Energy Holdings is an international company established to
be an operator of, and undertake active investment in, both proven and
innovative renewable energy technologies.

* REH owns two operational wind farm sites is Germany. Kesfeld
(32.5MW) and Kirf (8MW). In addition, REH is at various stages of development
of further wind farm sites in Poland and Wales.

* REH owns a 1MW methane Landfill Gas Project in Powys, Wales. The
long-term objective for this project is to increase production to 5-6MW.

* CETO is REH's innovative wave power technology. It is the first
wave power converter to sit on the seabed, where it is invisible, safe from
storms and ocean forces, and self contained. Unlike other wave energy
technologies that require undersea grids and costly marine qualified plant, CETO
requires only a small diameter pipe to carry high pressure seawater ashore to
either a turbine to produce electricity, or to a reverse osmosis filter to
produce fresh water.

* The Directors and executive team of REH have extensive experience in
both the conventional and renewable energy sectors, both in the UK and overseas,
and through their experience have built a broad international network of
relationships with individuals, companies, governments and lobby groups.

* The Company was incorporated in the Isle of Man on 8 October 2004
and listed on the London Stock Exchange's AIM Market in February 2005.
