The Pitfalls of Green Energy Revolution

Leave a reply

Video footage from a deep-sea mining test, showing sediment discharging into the ocean, has raised fresh questions about the largely untested nature of the industry, and the possible harms it could do to ecosystems as companies push to begin full-scale exploration of the ocean floor as early as this year. The Metals Company (TMC), a Canadian mining firm that is one of the leading industry players, spent September to November of 2022 testing its underwater extraction vehicle in the Clarion Clipperton Fracture Zone, a section of the Pacific Ocean between Mexico and Hawaii.

But a group of scientists hired by the company to monitor its operations, concerned by what they saw, posted a video of what they said was a flawed process that accidentally released sediment into the ocean. The scientists also said the company fell short in its environmental monitoring strategy, according to documents viewed by the Guardian newspaper.

As the push for deep-sea mining intensifies, experts are increasingly concerned that companies will kick up clouds of sediment, which could be laden with toxic heavy metals that may harm marine life. At least 700 scientists – along with France, Germany and Chile – are calling for a moratorium on deep-sea mining.

In a post to its website, TMC acknowledged the incident, but framed the discharge from its cyclone separator as a “minor event” in which “a small amount” of sediment and nodule fragments spilled into the ocean. The company said it fixed the issue in its equipment to prevent further overflows and concluded that the incident “did not have the potential to cause serious harm”.

Experts and critics caution that the incident highlights the relative uncertainties surrounding deep-sea mining. Companies are scrambling to scavenge the ocean floor for valuable metals, used in electric vehicle batteries and a host of other technologies such as green energy production, amid a global fight for stable supply.

The Plight of Electric Cars: Cobalt Batteries and Mining

Leave a reply

About 60% of the world’s cobalt is found in Congo, scattered across the copperbelt that stretches east into Zambia. The people of Kawama, Gongo grumble that too much land has been sold to mining firms. “We used to dig freely,” says Gerard Kaumba, a miner. “But now the government has sold all the hills.” There are still some sites where miners can turn up and dig, but they have to sell to whoever owns the concession. A sweltering day’s work might earn you $7. Many people have found they can make more at night, pilfering cobalt from industrial mines.

Glencore, a commodities giant with two mines in Congo, reckons that some 2,000 people sneak into its pits every day. Other companies have even more robbers to contend with. In 2019 Congolese soldiers chased thieves out of a mine owned by China Molybdenum where, it was reckoned, 10,000-odd people were then illegally digging. Sneaking into Glencore’s mines is hardest, says a Kawaman, as its guards do not collude with thieves—and often chase them away with dogs.

Congo’s industrial miners are not all angels.  Gécamines, the state-owned company, has enriched crooked politicians for half a century. Global Witness, a watchdog based in London, says Congo’s treasury lost $750m of mining revenues to graft between 2013 and 2015. ENRC, which has mines in Congo, has faced allegations of corruption and an investigation by Britain’s Serious Fraud Office (it denies wrongdoing). So has Glencore, which has worked with Dan Gertler, an Israeli billionaire. Mr Gertler, a close friend of a former Congolese president, Joseph Kabila, is under American sanctions… 

While big firms rake in millions, many of the little guys languish in jail. The prison in Kolwezi, the largest city in the mining region, is crammed with men caught stealing copper and cobalt. More than a hundred inmates occupy one stinking room, sitting in rows on the ground, each wedged between another’s legs. Prissoners are allowed to use the toilet only once a day, so they often urinate in their clothes

Mining the Ocean: the Fate of Sea Pangolin

A snail that lives near hydrothermal vents on the ocean floor east of Madagascar has become the first deep-sea animal to be declared endangered because of the threat of mining.  The International Union for Conservation of Nature (IUCN) added the scaly-foot snail (Chrysomallon squamiferum) to its Red List of endangered species on 18 July, 2019 — amid a rush of companies applying for exploratory mining licenses…. The scaly-foot snail is found at only three hydrothermal vents in the Indian Ocean.  Two of those three vents are currently under mining exploration licences,…Even one exploratory mining foray into this habitat could destroy a population of these snails by damaging the vents or smothering the animals under clouds of sediment..

Full-scale mining of the deep seabed can’t begin in international waters until the International Seabed Authority (ISA) — a United Nations agency tasked with regulating sea-bed mining — finalizes a code of conduct, which it hopes to do by 2020….The biggest challenge to determining whether the scaly-foot snail warranted inclusion on the Red List was figuring out how to assess the extinction risk for animals that live in one of the weirdest habitats on Earth…

When the IUCN considers whether to include an organism on the Red List, researchers examine several factors that could contribute to its extinction. They include the size of a species’ range and how fragmented its habitat is…The IUCN settled on two criteria to assess the extinction risk for deep-sea species: the number of vents where they’re found, and the threat of mining.   In addition to the scaly-foot snail, the researchers are assessing at least 14 more hydrothermal vent species for possible inclusion on the Red List.
