  • Project to develop a technology platform to build blades in excess of 100 metres
  • Use of carbon fibre in manufacture enabled longer blades with increased swept area to be built
  • Manufactured through smaller component pieces rather than full-length mouldings

The ETI commissioned Isle of Wight SME Blade Dynamics to develop a technology platform to build blades in excess of 100m for use on the next generation of large offshore wind turbines with a capacity of 6MW.

New design techniques were used incorporating carbon fibre along with other composite materials.This created blades weighing up to 40% less and allowed for cost savings in the overall blade, turbine and tower structure to be made, when the system is designed as a matched unit. This helps reduce the cost of energy.

The manufacturing process sees the blades constructed through the assembly of smaller, more accurate and easily manufactured component pieces as opposed to the traditional large and expensive full-length mouldings.

In October 2015, Blade Dynamics was acquired by GE.The acquisition by one of the world largest companies and the resources and market reach they bring with them should enable the technology to progress quickly and reach a wide global market.

How many undocumented children live in London?
Estimating the numbers of migrants in the UK is notoriously difficult, especially those with an irregular migration status who may not be counted in official government statistics. It is not for nothing that the task has been described as counting the uncountable. However, information about the population of children and young people who are not…20/01/20

Future of wind
This study presents options to speed up the deployment of wind power, both onshore and offshore, until 2050. It builds on IRENA’s global roadmap to scale up renewables and meet climate goals.
Decarbonisation of Heat: Why It Needs Innovation - Emily Sotudeh
Decarbonising heat is key to achieving Net Zero, and innovators have a vital role to play. Here is our overview of the decarbonisation challenge and how we can tackle it through low carbon home heating innovation.\nThe post Decarbonisation of Heat: Why It Needs Innovation appeared first on Energy Systems Catapult.
Why are Local Authorities going against UK Government on fracking?
Across the UK, Local Authorities, and Devolved Administrations, are seeking to use their planning powers to block the development of hydraulic fracturing for natural gas. This is against UK Government policy. Here, Dr Sarah Mander looks at what all of this could mean for the future of shale in the UK.

PRESS RELEASE: Government deployment stats fail to accurately capture >50kW PV systems - Jack Dobson-Smith
The STA continues to call on the Government to address serious flaws in the accuracy of its photovoltaic deployment data following the publication of its latest statistics, which state that solar deployment in 2019 was down by over 60MW compared to 2018, suggesting the slowest year for the industry since 2010. [1] However, the statistics fail to accurately capture PV systems sized above 50kW, with no update to the ‘50 kW to ≤ 5 MW’ category since March 2019, and only one large-scale site added to ‘> 25 MW’ category in 2019, a 34.7MWp array completed in December by GRIDSERVE. ... \nRead More\nThe post PRESS RELEASE: Government deployment stats fail to accurately capture >50kW PV systems appeared first on Solar Trade Association.
