Wind turbines are a renewable energy source receiving a lot of attention these days, and the locations of the massive wind farms that stretch for miles are becoming more and more remote. Wind energy developers are literally chasing the wind to find the optimal locations for maximum wind exposure, and at times these locations may not be the most practical for turbine construction. Take the deep sea for example. While offshore wind farms—like the U.K.’s Thanet wind farm—have certainly captured the energy of the sea breeze, it is the deep sea, where turbine towers cannot reach the bottom of the ocean floor, where you find the highest velocity and most consistent wind.

Necessity is the mother of invention, and the need to access the winds of the high seas has led to an innovative joint venture between Vestas and WindPlus. Vestas—a global leader in wind turbine technology—is pursuing floating wind turbines to be deployed in deep waters. WindPlus is a joint venture group including partners EDP Group and Principle Power, and will deliver, install and commission the Vestas turbines.

Principle Power is the company that has designed the WindFloat system to be used by Vestas and WindPlus. The unique design is intended to reduce wave and turbine-induced motion. This allows for the turbine to be placed floating in waters greater than 164 feet (50 meters) deep.

Currently there is only one operating floating wind farm in the world. The Hywind farm in the North Sea near Norway was commissioned by oil and gas company, Statoil, in 2009. However, Vestas and WindPlus are hoping to make the floating wind turbine more commonplace than rarity. The Vestas floating wind turbine is set to be revealed sometime in 2011.

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.
