He said that traditional offshore windmills seemed to have reached their economic limit with the huge 10MW turbines that are planned for the next few years, but Nova could potentially deliver more. “No one understands the economic limits for vertical-axis and it may be the economic limit is significantly better than a 10MW can provide, so we will be able to generate electricity at a much lower cost. The design could be more reliable and the maintenance costs could be significantly lower because the main components are actually closer to sea level than they are with the horizontal-axis design,” said Bourhill.
ova, which has collaborators from Cranfield, Sheffield and Strathclyde universities, is being developed by OTM Consulting Limited. The team aims to have 1GW of offshore vertical axis turbines installed by 2020, with a demonstrator Aerogenerator turbine built offshore by 2015. Each windmill would be designed to generate between 5MW and 10MW of power but, because each would be cheaper to build than an equivalent modern turbine, the overall cost of an offshore wind farm, and the electricity, should be lower.
The ETI’s strategy for offshore wind is to find ways to make this source of energy much cheaper and more reliable. The other two projects funded by the institute’s £20m offshore scheme are Helm wind, a consortium led by energy company Eon that is focused on examining how conventional windmill designs can be made more cheaply, and Project Deepwater, a design for floating windmills out at sea led by Blue H Technologies and which includes collaborations from BAe Systems and EDF energy.
The ETI’s funding for the three projects so far is aimed at producing detailed design specifications for the three ideas. Bourhill said that, once these plans have been evaluated by the institute, one of the ideas will be in line for a multi-million pound demonstration project.

When faced with the need to develop additional sources of energy, the
Ethiopian Electric Power Corporation recently decided that its best option
was not to build conventional power plants.
Instead, the electricity provider opted to fulfill its energy needs by building
The 120 megawatt Ashegoba plant in north Ethiopea will provide
for 15 percent of the nation’s present energy capacity.
Up until now Ethiopia has relied upon hydroelectric dams as an important
energy source, although recently this strategy has been crippled by severe droughts
that strain the country’senergy grid to the point of collapse. EEPC chairman
Meheret Debebe has stated that the newwind power project “will help us to
fill the gap of hydrological risks we are facing in Ethiopia with the droughts”.
The cost for the project will be 220 million euros, and it is expected to hit
a peak production ofover 120 megawatts when it is finished in about two
and a half years. Africa’s investment in the green revolution will
ensure that the continent stands well poised to tackle future
challenges, and this is a great first step.
