A fresh research initiative seeks to transform how wind turbine towers are constructed.

Coordinated by the Offshore Renewable Energy Catapult, the work will centre on towers for land-based wind farms initially, though expansion into maritime installations may follow.

The partnership bringing the scheme to life comprises Tata Steel UK, RWE, Bute Energy, Hutchinson Engineering and Ledwood, with its principal operations located in Wales.

Funding of £174,000 has been obtained through the Welsh Government’s SMART Flexible Innovation Support programme.

Dr Cristina Garcia-Duffy, who heads research and engineering at ORE Catapult, explained that this advancement marks significant progress in turbine tower engineering, offering the prospect of markedly improved technical capabilities alongside considerable economic and ecological advantages for Wales and the rest of Britain.

At present, the majority of British wind turbine towers utilise imported heavy-gauge steel sheeting.

The initiative intends to create an innovative tower concept employing lighter, lower-emission steel manufactured in electric arc furnaces, which could bring down expenses, decrease mass and lessen environmental consequences.

Sumitesh Das, director at Tata Steel Research and Innovation Limited, noted the company’s enthusiasm for involvement in this venture, working alongside Tata Steel UK’s business development divisions to produce strip steel designs suitable for land-based turbines, marking an unprecedented development in the field.

The tower concept will incorporate construction methods drawn from the naval and aviation industries to guarantee robustness and longevity.

It will also feature compatibility with currently available turbine and base configurations.

Rebecca Evans, the Welsh Government’s cabinet secretary responsible for economy, energy and planning, pointed out that this funding illustrates the government’s determination to foster a more sustainable and more prosperous Welsh economy.

By supporting indigenous innovation and regionally produced low-emission steel, authorities are contributing to the creation of well-paid positions, reinforcing supply networks and establishing Wales as a leader in the international offshore wind sector.
