According to Mining News Pro – According to Craig Buckley, a professor from the School of Electrical Engineering, Computing and Mathematical Sciences who is working on the project, the battery uses a high-temperature metal hydride or metal carbonate as the heat storage medium and a low-temperature gas storage vessel for storing the hydrogen or carbon dioxide.

    *The Australian federal government awarded A$1 million to the project*

“At night, and in times of cloud cover, hydrogen or carbon dioxide is released from the gas storage vessel and absorbed by the higher temperature metal to form a metal hydride/metal carbonate, which produces heat used to generate electricity,” Buckley said.

This means that the prototype is able to store and, as required, release solar energy without reliance on sunlight at all times. This solves the storage issue that hinders most renewable energy projects.

The overall idea is to integrate thermochemical energy storage via a thermal battery into a dish-Stirling system. Such a system can provide up to 46 kW of power and is ideal for powering remote energy-intensive industries such as mine sites due to it providing power on demand and as required. Several dishes can be deployed depending on the power requirements of the site.

“As with the lithium battery systems that Curtin is also developing, the deployment of a cost-effective energy storage system using thermal batteries will revolutionise the landscape of renewable energy production worldwide by allowing renewables to truly compete with fossil fuels,” Chris Moran, Curtin University Deputy Vice-Chancellor Research, said in a media statement. “While a lithium battery stores electrical energy that can be used to provide electricity when the sun is not shining, this thermal battery stores heat from concentrated solar thermal, which can be used when the sun is not shining to run a turbine to produce electricity.”

According to Mining News Pro – In an interview in New Delhi, Gautam Adani took aim at two major faults opponents have flung at the development: that the mine’s low-quality coal won’t earn enough money to justify his $2 billion investment, and that the world must abandon the fuel in favor of renewable energy to avoid catastrophic climate change.

“Renewable energy is good for the nation, but it can’t meet our baseload power needs”
Gautam Adani

“If the project wasn’t viable, we wouldn’t have pursued it,” said Adani, whose net worth of $9.8 billion makes him India’s sixth-richest person, according to the Bloomberg Billionaires Index. “Renewable energy is good for the nation, but it can’t meet our baseload power needs.”

Adani bought the resource in Australia’s Galilee Basin in 2010 as Indian companies rushed for overseas energy supplies amid forecasts of booming demand. But as coal prices fizzled through the first half of the decade, Carmichael’s output — closer to lower-quality Indonesian coal than the high-value varieties Australia is known for — is seen unable to fetch a price strong enough to be profitable.

“The commerciality of Adani’s Carmichael mine remains challenging given the significant capital spend and low-quality thermal coal product expected from the mine,” said Brent Spalding, a principal analyst at Wood Mackenzie Ltd.
Climate warnings

Australia’s Newcastle coal, a benchmark in Asia, would need to rise above $100 a metric ton, from about $78 now, for Carmichael to break even, according to Spalding.

Carmichael, which cleared final state approvals last month, will open up a new mining basin in the Australian outback amid increasingly dire warnings of the need to cut carbon emissions to avoid the ecological and economic havoc of climate change. Though coal is the most carbon-intensive fossil fuel, Adani has found a relatively friendly host country in Australia, where the economic heft of the resource industry helped re-elect a pro-coal federal government and overcome staunch opposition from environmentalists.

“We entered Australia with two overarching goals; contributing to energy security in India and creating job opportunities for the locals,” said Adani, 57, who started as a diamond trader in Mumbai before setting up Adani Group in 1988. His conglomerate — spanning ports, energy and mining — has become one of India’s key infrastructure service providers, while also venturing overseas.
Surplus generation

Coal’s use has been on the decline in Europe and the U.S. amid cheaper alternatives and pressure to ditch the most-polluting fossil fuel. Yet it dominates power production in much of Asia, a position it’s expected to sustain despite a boom in cleaner sources, such as wind and solar, as energy demand continues to grow.

Adani said the board approved 10 million metric tons of annual output from Carmichael’s first phase, which will head to his power plants in India, including Mundra and Godda. Adani Group is headquartered in Gujarat the state where current Prime Minister Narendra Modi served as the chief minister for little over a decade before he swept national elections in 2014.

India’s per-capita consumption of electricity “is way below the global average,” Adani said. “India’s development is linked to the availability of more power. And coal will play a big role in this as a baseload supplier.”

India’s challenges supplying reliable power to every home have been more about distribution than whether it has enough power plants or coal. The nation already has a surplus of generation capacity, but it’s money-losing, debt-saddled state utilities struggle to purchase and distribute enough power, leaving some power stations shuttered and homes in the dark.

When the company decides to raise the capacity of Carmichael — peak annual capacity is now seen at 27 million tons, down from an original 60 million — it will explore selling washed coal to buyers in Japan and Korea, according to Adani. Construction has already begun, he said, reiterating the company’s two-year timeline for first output.

According to Mining News Pro – The company said the stone will go on sale at the next tender, which is scheduled to take place in September.

The find follows the recovery of a 72-carat yellow, whole makeable diamond in early April, which was the second one over 70-carat Firestone has found this year at Liqhobong.

“While Liqhobong has become known for its fancy yellow stones, this one is the largest we’ve recovered so far”
Chief executive Paul Bosma

“Sawable” stones can be cut in half in order to create two smaller diamonds. In contrast, “makeable” ones are those whose shape allows to cut only one large diamond from it.

“The Liqhobong mine has become known for its fancy yellow stones, but this one is the largest we’ve recovered so far and is therefore quite special,” chief executive Paul Bosma said in the statement.

Bosma added that while certain segments of the diamond market were currently struggling, the demand for unique natural stones remained positive.

In March, Firestone halted plans to extend the life of the mine, as market conditions didn’t support the project.

The company spent $185 million building Liqhobong, which started production in late 2016, and boasts over 11 million carats in reserve. The total open pit resource contains over 17 million carats to a depth of 393 metres.

According to Mining News Pro – Mining international waters is in the spotlight as companies and countries are looking at minerals concentrated on the ocean floor that can be used in batteries for smart phones and electric vehicles.

Greenpeace, which wants a moratorium at least until the ocean depths are better understood, issued a report this week warning seabed mining risks doing irreversible harm and said the 168-member ISA should not set the rules.

Tensions between campaigners and the ISA coincide with talks throughout July in Jamaica, where the U.N. body is headquartered, ahead of a 2020 goal its member states have set to agree rules on seabed mining. So far only exploration has been allowed.

The ISA was established to manage seabed minerals by the United Nations Convention on the Law of the Sea (UNCLOS), effectively a constitution for the oceans

ISA Secretary General Michael Lodge said the Greenpeace report was wrong “particularly in relation to the existing legal regime set up by international law”.

The ISA says it has the right to set the rules as it is a transparent public forum of consensus-building by the international community and in compliance with international law.

Lodge said Greenpeace’s demands for a “global ocean treaty” rather than the ISA to govern ocean mining did not make sense.
Future generations

Greenpeace stood by its report on Friday.

“We think that this treaty should establish a body that has oversight of activity affecting biodiversity, and have the mandate to protect it for future generations given none of the bodies set up by UNCLOS thus far has that mandate nor the capability/oversight,” it said in an email to Reuters.

The ISA was established to manage seabed minerals by the United Nations Convention on the Law of the Sea (UNCLOS), effectively a constitution for the oceans, Lodge said in a telephone interview.

For many years, the debate was academic and mining companies doubted ocean bed mining could be economic. That has changed as some nations and companies see it as an effective way to get polymetallic nodules containing nickel, copper, cobalt and manganese.

Even if the ISA agrees exploitation law, mining would not take place for years given the technical difficulties.

Royalties would be paid to the ISA for distribution, the bulk of which in theory could be to emerging economies.

This month’s talks could debate whether China – which holds four of the 29 ISA exploration contracts granted so far, the most by any country – is an emerging economy.

The ISA is also considering granting another exploration contract to China, Lodge said.

Other nations active in the deep seas include Russia, Britain and Belgium.

The United States is not in the ISA but Britain is and Lockheed Martin’s British unit UK Seabed Resources has two exploration contracts.

According to Mining News Pro – This contract includes selling 50 thousand tons of pellet with 64 percent of the grade.

The 50 thousand tons of cargo will be carried in July 2019.

In the 2019 financial year, Ispat and Godawari Company produced 19.3 million tons of pellet, up by 5 percent comparing to the last financial year. The company is focusing on producing high grade pellet.

Jindal Steel & Power also conducted a tender offer in Eastern India for 50 thousand tons of pellet export with 64 percent of grade, According to the reports; this tender offer will be held this week with CFC of 131 dollars.

The study shows that the export price of Indian pellet from India to China has grown compared to the last week and increased from $128 CFR to $131 CFR.

Due to demand increase of Chinese companies and supply reduction in the ports, the price of India’s pellet has increased. Chinese steelmakers are seeking to reduce the price of raw materials.

The export volume of India’s pellet in 2019 financial year is about 1.1 million tons with 34 percent growth compared to the last year. It means that India has exported 880 thousand tons of pellet each month.
