Duke Energy was cited Thursday for illegally and deliberately unloading as much as 61 million gallons of toxic coal ash waste into Cape Fear River, a water source in North Carolina.

In February, Duke faced controversy during the Dan River disaster, in which a pipe burst into the Dan River, releasing 82,0000 tons of coal ash into the pond. Thursday’s disposal of coal ash waste marks the eighth time in less than a month that Duke has faced charges with violating environmental regulations.

Though Duke is legally able to dispose treated wastewater into the canal, they must abide regulations including filtering the water through “risers,” so that the residue in the water is able to settle. However, The North Carolina Department of Environment and Natural Resources reported that Duke did not follow proper protocol in discharging the waste.

In the North Carolina Department of Environment and Natural Resources’ Notice of Violation, “the 1978 ash pond was approximately 6 feet below the normal water elevation and the 1985 ash pond was approximately 7-8 feet below the normal water elevation.” In order for Duke to follow proper protocol in disposing of the ash waste, water elevation must exceed the normal standard for water elevation. In this case, it did not.

Aerial footage of the illegal dumping was caught by Waterkeeper Alliance, an environmental group that aims to sustain safe water qualifications for swimming and ingesting worldwide. In an attempt to reach the pond, Waterkeeper Alliance were restricted by plant employees and a policeman, in which they turned to recording the incident via aerial vision.

Among the harmful toxins included in coal ash generated from coal plants are lead, mercury, arsenic, chromium, and selenium, all harmful substances for all who ingest them. Mercury poisoning can cause sensory impairment and can harm coordination, among other serious side effects.

Though Duke is a prime accused offender in placing harmful residue in water reservoirs, the U.S. Justice Department is continuing a criminal investigation of DENR and their relationship with Duke in light of the poor handling of Duke’s continuous violations. According to The Climate Progress, “the Associated Press recently acquired emails suggesting the staff at DENR was working with Duke Energy Officials before intervening in a suit by citizen groups against the company.”

North Carolina is also known for its refusal to accept climate change as fact. In 2012, North Carolina passed a law forbidding the state for predicting sea level rise and confirming the existence of climate change. The new law prompted critics and some politicians to deem North Carolina as blind to climate change, small-minded and leaving the state in denial.

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.
