Energy Globe Award

With more than 178 participating countries and over 2000 project submissions annually the Energy Globe Award is today's most prestigious environmental prize worldwide. It distinguishes projects regionally, nationally and globally that conserve resources such as energy or utilize renewable or emission-free sources. Award ceremonies are held all over the world. Prominent personalities as well as Energy Globe Ambassadors in 90 countries support the mission of Energy Globe. The activities of Energy Globe attract worldwide media attention - international TV stations report each year with approximately 1,000 hours of broadcasting time. The aim of the Energy Globe is to raise global attention on sustainable, everywhere applicable environmental solutions and to motivate people to also become active in this area.

Propeller buffing

Conventional propeller maintenance causes harm to the environment. Hydrex developed a method which saves fuel and reduces water pollution.

Initial situation
The traditional approach in the propeller maintenance industry is to polish it with a grinding disk which can be quite damaging to the propeller. By the very fact of using a grinding disk, a substantial amount of metal is removed from the propeller itself. This can alter the shape and efficiency, cause roughness and increase rather than reduce friction. This roughness has several ecological and economical aspects. A rough propeller can consume up to 10% of additional fuel. This is an economical problem, but also an ecological one because of the increased greenhouse gas emission. Then there is the aspect of the polluting particles dropping into the sediment, making it a source of marine pollution which is a problem in a number of ports.

Hydrex discovered that more frequent, lighter cleaning of the propeller using a different tool to a grinding disk, and catching the propeller before a calcareous layer builds up is actually the optimum approach to propeller cleaning. If done right and done regularly it can result in 5% or even more fuel savings. No material is ground away, which is good for the propeller and the environment.

Until that breakthrough, there were no smooth propellers. For a ship that has a medium level of fuel consumption, the savings far outweigh the cost of the propeller cleaning itself. Because the propeller is being cleaned regularly, the cleaning is relatively light and quick.

We are an enthusiastic supporter of the Energy Globe Awards and its aim to strengthen society’s awareness of the necessity for ecological change, by honouring outstanding best practice projects in environmental sustainability from all parts of the world. ADVANTAGE AUSTRIA is the official Trade Promotion Organisation (TPO) of the Republic of Austria and as a country we are proud of our success in green technologies. Our support of the Energy Globe Awards continues this tradition.
