Description: Wave energy is an emerging technology and a suite of diverse systems have been designed and are being tested. Most of these technologies aim to generate electricity in-water, and then transmit this ashore. Waves represent the optimum energy source for significant sustainable local power generation.

Bermuda is an ideal location to demonstrate the commercial technological viability and profitability of cutting-edge, wave-energy generating technology.

Renewable Energy Bermuda
A wave energy solution for Bermuda, in partnership with Bermuda

Presented at the Town Hall Meeting hosted by

GOVERNMENT OF BERMUDA
Ministry of Energy, Telecommunications and E-Commerce
September, 2008

Why Choose Wave Energy?
Waves � the facts Waves contain more energy and are more consistent than solar and wind energy. Wave patterns are more predictable than other forms of renewable energy. Wave energy projects have a very low environmental impact. Wave energy projects do not compete for limited land resources. Wave energy projects benefit from being close to shore. This image shows the global distribution of wave energy. "2TW of energy, the equivalent of twice the world's electricity production, could be harvested from the world's oceans on a continuous basis." World Energy Council

Bermuda

Why Bermuda is Ideally Suited to Wave Energy Power
Bermuda � the facts Bermuda is 98% dependent on petroleum imports, has high electricity rates and increasing demand. Bermuda has an excellent wave regime and very little tidal activity. Bermuda has a fragile ecosystem that underpins the economy. Bermuda must manage intense competition for limited land resources. Bermuda has easy access to deep water in close proximity to the shore.

Bermuda lends itself to wave energy power generation due to the lack of large tides and the regular 2m swells, as depicted in the SATOBSYS plot, above right.

Advantages of Wave Energy to Bermuda
Wave energy utilisation in Bermuda will; Reduce our dependence on oil imports and improve our security Have a stabilizing affect on the cost of electricity Utilise a reliable, indigenous energy supply Have zero harmful emissions and will reduce our carbon footprint Showcase Bermuda as a centre of excellence in wave energy power technology

Waves represent the optimum energy source for significant sustainable local power generation. Bermuda is an ideal location to demonstrate the commercial technological viability and profitability of cutting-edge, wave-energy generating technology.

Wave Energy Technology Options
Wave energy is an emerging technology and a suite of diverse systems have been designed and are being tested. Most of these technologies aim to generate electricity in-water, and then transmit this ashore. None of these is felt to be appropriate for Bermuda.

Best Wave Energy Solution for Bermuda
In searching for the most appropriate wave energy solution for Bermuda, local company Triton Renewable Energy identified the following criteria;
Given the ecological and aesthetic value of Bermuda's environment to our quality of life and economy, the technology should be located offshore rather than in the nearshore environment to minimise the environmental and visual impact. Where possible, the technology should employ `tried and tested' and robust component parts with a minimum of submerged electrical components and with an extensive and reliable support network. Components should be simple and inexpensive, to facilitate maintenance. There should be a viable business model and any partners should have a proven track record in the renewable energy sector. The "roll out" schedule for the technology should be within a realistic and deliverable timeframe, and should be modular to allow for expansion.

After several years of background research and fieldwork, Triton determined that the most suitable wave energy technology for Bermuda was the CETO technology being developed by Renewable Energy Holdings (REH) and EdF Energies Nouvelles S.A.

REH's CETO Wave Technology
The basic components of REH's CETO technology are shown below. CETO operates as a pump. Submerged buoys harness the ocean energy to drive CETO units, which pump seawater ashore at high pressure. The pressurized water is then used to drive onshore turbines to create base load electricity. The pressurized seawater can also be desalinated via reverse osmosis to create zero emission freshwater.
