Turbine rotor blade supplier LM Wind Power has

Turbine rotor blade supplier LM Wind Power has unveiled the world’s longest-ever wind turbine blade, which has just been completed at a factory in Lunderskov, Denmark.

At 88.4 metres long, the blade is longer than a Boeing 747-8 jet airliner, which measures 76 metres long.

The blade has been specifically designed for turbine manufacturer Adwen’s AD 8-180 offshore wind turbine model, which boasts an 8MW nominal capacity and a rotor diameter of 180 meters. A single AD 8-180 turbine has the highest annual energy production (AEP) of all wind turbines and will be capable of powering around 10,000 homes.

LM Wind Power's CEO, Marc de Jong said in a statement: "The LM 88.4 P blade is an extraordinary example of industrialized innovation at record breaking scale.

“This blade is a strong proof point of the shared ambition of Adwen and LM Wind Power to bring forward best in class and proven rotor solutions for offshore application, increasing Annual Energy output through efficient and reliable technology."

The blade will now be transported to a facility in Aalborg, Denmark for testing.

An onshore prototype of the AD 8-180 turbine is going to be installed in Bremerhaven, Germany by the end of this year. Serial production is expected to get underway in 2018.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
