Renewable energy is in great demand and it could be growing even stronger.

Power generation from renewables is expected to exceed that of gas and nuclear by 2016 and could comprise almost a quarter of the entire global power mix by 2018. Last year, Germany set a new national record for energy by meeting 78 percent of the day’s electricity demand with renewable sources.

The majority of renewable forms of energy, other than geothermal and tidal power, ultimately come from the Sun. Some forms are stored solar energy such as rainfall and wind power, which are considered short-term solar-energy storage, whereas the energy in biomass is accumulated over a period of months, as in straw, or through many years as in wood.

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.
