Turning Tide of Technology

Article excerpt

RENEWABLE energy has become an important consideration as concerns about dependence on fossil fuels and finding feasible alternatives have become a key challenge in the energy sector.

What the mix of energy resources will be in the future is certainly not clear. But the more practical an alternative source and the more proven it is in operation will have an influence on governments, policy makers, insurers and investors.

Energy generation based on tidal current is a practical and alternative solution to land-based installations and represents an important area of innovation for ANDRITZ HYDRO Hammerfest.

The company, part of the ANDRITZ HYDRO group, represents a leading technology provider in the tidal power business capable to generate clean, renewable and predictable energy from tidal currents occurring in coastal waters.

Tidal turbines are freestanding machines that can be thought of as "underwater wind turbines", spinning as the tidal flow moves past them.

In December 2011, ANDRITZ HYDRO Hammerfest successfully deployed a 1MW pre-commercial tidal turbine to validate the technology for the world's first tidal power arrays. The turbine was installed at the European Marine Energy Centre (EMEC) in Orkney, Scotland.

The HS1000 tidal turbine was commissioned and synchronized to the power grid - delivering power at the first attempt during initial start-up. It is based on the technology of an earlier prototype, a smaller turbine with 300kW electrical output. The prototype has been at work in Norway, as the first ever tidal current turbine with permanent connection to the public grid in 2004. The prototype has been in operation for more than 17,000 hours, delivering power to the grid with 98% availability.

The EMEC site is considered to be one of the more hostile worldwide. Installation of the HS1000 occurred during one of the worst periods of the year - with extremely strong winds and high waves. …
