  1. Produzione mondiale di nichel: dominio dell’Indonesia e crisi delle miniere occidentali
    metallirari.com/produzione-mon
    Per capire oggi il mercato del nichel bisogna partire dall’Indonesia. Nel 2025 il paese ha concentrato il 67% della produzione mondiale, diventando il fattore decisivo per prezzi, investimenti e sopravvivenza delle miniere in tutto il resto del mondo.

  3. Nichel sotto i 17.000 dollari. Il mercato teme più minerale dall’Indonesia
    metallirari.com/nichel-sotto-1
    Il nichel scende a 16.760 dollari per tonnellata mentre il mercato teme che la revisione delle quote RKAB in Indonesia possa essere più ampia delle attese, aumentando l’offerta disponibile nel 2026.

    Il rimbalzo del nichel (+27% nel 2026) porta sollievo ai grandi produttori, ma la crisi di approvvigionamento dello zolfo mette sotto pressione gli impianti indonesiani.

  5. #SodiumIonBatteries offer an alternative to tricky #lithium

    Oct 26th 2023

    Excerpt: "Fortunately, lithium is not the only game in town. As we report this week, a clutch of firms are making batteries based on sodium, lithium’s elemental cousin. Since sodium’s chemical properties are very similar to those of lithium, it too makes for good batteries. And sodium, which is found in the salt in #seawater, is thousands of times more abundant on Earth than lithium and cheaper to get at. Most of the companies using sodium to make batteries today are also Chinese. But pursuing the technology in the West might be a surer route to energy security than relying heavily on lithium.

    "Besides its abundance, sodium has other advantages. The best lithium batteries use #cobalt and #nickel in their electrodes. Nickel, like lithium, is in short supply. #Mining it on land is #EnvironmentallyDestructive. Proposals to grab it from the #seabed instead have caused rows. A good deal of the world’s cobalt, meanwhile, is extracted from small mines in the #DemocraticRepublicOfCongo, where #ChildLabour is common and working conditions are dire. Sodium batteries, by contrast, can use #electrodes built from #iron and #manganese [and wood #lignin], which are plentiful and uncontroversial. Since the chemical components are cheap, a scaled-up industry should be able to produce batteries that cost less than their lithium counterparts.

    "Sodium is not a perfect replacement for lithium. It is heavier, meaning sodium batteries will weigh more than lithium ones of an equivalent capacity. That is likely to rule them out in some cases where lightness is paramount. But for other applications, such as #GridStorage or #HomeBatteries, weight is irrelevant. Several Chinese carmakers are even beginning to put sodium batteries in #ElectricVehicles."

  6. New method converts old phones and paper industry #waste into #GreenBattery tech

    Scientists have created a sustainable, cost-effective, and highly efficient solution that promotes a #CircularEconomy while supporting the transition to greener #EnergyStorage.

    "A new sustainable method turns discarded #MobilePhoneBatteries and industrial lignin into a powerhouse material for #SodiumIon batteries.

    "It is a stunning example of circular economy innovation. Rather than letting these materials sit in #landfills or go up in smoke, the team from China is giving the waste a high-tech second life.

    "When tested as a sodium-ion battery anode, this composite of #nickel-#cobalt sulfides and #lignin-derived carbon delivered electrochemical results."

  7. Environmental Impacts of #Geothermal Energy

    Published Mar 5, 2013
    Union of Concerned Scientists

    "The most widely developed type of geothermal power plant (known as #hydrothermal plants) are located near #geologic#HotSpots” where hot molten rock is close to the earth’s crust and produces hot water. In other regions enhanced geothermal systems (or hot dry rock geothermal), which involve drilling into Earth’s surface to reach deeper geothermal resources, can allow broader access to geothermal energy."

    [...]

    "Some geothermal plants also produce small amounts of #mercury emissions, which must be mitigated using mercury filter technology. Scrubbers can reduce air emissions, but they produce a watery #sludge composed of the captured materials, including #sulfur, #vanadium, #silica compounds, chlorides, #arsenic, mercury, #nickel, and other heavy metals. This #ToxicSludge often must be disposed of at hazardous waste sites."

    [...]

    "Land #subsidence, a phenomenon in which the land surface sinks, is sometimes caused by the removal of water from geothermal reservoirs. Most geothermal facilities address this risk by re-injecting wastewater back into geothermal reservoirs after the water’s heat has been captured.

    "Hydrothermal plants are sited on geological “hot spots," which tend to have higher levels of #earthquake risk. There is evidence that hydrothermal plants can lead to an even greater earthquake frequency. Enhanced geothermal systems (hot dry rock) can also increase the risk of small earthquakes. In this process, water is pumped at high pressures to fracture underground hot rock reservoirs similar to technology used in natural gas hydraulic #fracturing. (See How Natural Gas Works for more information.) Earthquake risk associated with enhanced geothermal systems can be minimized by siting plants an appropriate distance away from major fault lines. When a geothermal system is sited near a heavily populated area, constant monitoring and transparent communication with local communities is also necessary."

  8. Hur mycket metaller används för solenergi och vindkraft
    Solenergi behöver framförallt koppar och kisel. Vindkraftverk använder huvudsakligen koppar och zink men också mindre mängder mangan, krom och nickel.

  9. Det är ohållbart att vara beroende av Kina
    För klimatomställningen behövs sällsynta jordartsmetaller som dysprosium, neodym till elmotorer, vindkraftverk och batterier, litium, kobolt, nickel, mangan är andra metaller som behövs till elbilar och batterier. Grafit behövs också till batterier
