According to research by Cadent, a UK-based gas distribution firm, biogas produce from domestic waste could generate enough power to fuel 15mn homes by 2050.

This would be enough energy to cover households across the south east of England, London, and East Anglia.

Cadent claim this could be the most effective way to manage the large amounts of waste produced in the UK, as well as creating green energy.

The firm suggest that biogas could grow significantly in the next 30 years, allowing black domestic bag rubbish, agricultural waste, energy crops, food waste, and sewage to generate 183TWh of biomethane.

“The findings of this report show that with the right policies in place renewable gas could play a significant role in helping the UK meet its carbon reduction targets, particularly in heat and transport, which are lagging behind electricity,” commented Cadent Director of Network Strategy, David Parkin.

“Alongside other green energy solutions, renewable gas offers us an affordable, sustainable route to heat our homes and fuel transport, while tackling climate change, and contributing towards more sustainable waste management and cleaner air.”

In the report, Cadent propose that two-thirds of renewable gas could be sourced from energy crops and agricultural residues, with the remaining third coming from waste. Of that third, 83% would be produced by Bio-Substitute Natural Gas (BioSNG) and 17% would derive from biomethane, generated by anaerobic digestion.

Cadent are aiming to work with the UK government in order to initiate a journey towards decarbonisation.

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.
