Coal plays a huge role in global electricity generation, but has a significant impact on the environment.

From Pennsylvania to the north of England, coal mines helped to power the Industrial Revolution, turbocharging the economic growth of countries around the world.

Today, however, the production and use of coal has become a thorny issue, with critics slamming the fossil fuel’s huge impact on the environment.

Organizations like Greenpeace describe coal as “the dirtiest, most polluting way of producing energy.” From the UN Secretary General to the International Energy Agency, talk of phasing out coal is becoming increasingly common.

But the global picture is a complex one. A multitude of factors are in play, not least the desire of some countries, especially those in emerging markets, to use coal as a tool for their own economic development.

As the debate surrounding coal continues, discussions about using it — and the infrastructure linked to it — in the shift to a more sustainable future have become one of the more paradoxical aspects of the energy transition.

In May, U.S. firm Ramaco Resources offered some insight into how coal may have a role to play in the years ahead.

Together with researchers from mining consultancy Weir International and the U.S. Department of Energy’s National Energy Technology Laboratory, it published an independent report containing a technical assessment of rare earth elements, or REE, found at one of its mines in Wyoming.

The findings appear to be significant. “Following eighteen months of extensive core drilling and independent chemical analysis, NETL researchers and Ramaco now believe that the Brook Mine property contains perhaps the largest unconventional deposit of REEs discovered in the United States,” Ramaco said.

Speaking to CNBC’s Kelly Evans on “The Exchange” earlier this month, Ramaco CEO Randall Atkins explained why his firm had bought the site in the first place, and how its plans had changed over time.

“It was a rather large reserve, extremely reasonably priced, and we thought we might make a go of it just as a thermal coal proposition but you know, the world changed rather quickly about 10 years ago,” he said.

“And the idea of deploying capital towards a thermal mine became very unattractive. So our approach was, basically, ‘what else can we do with this stuff?'”

This led the company to “a 10 year odyssey of discovering a variety of other alternative uses of coal.”

With China dominating the supply and refining of rare earths, discoveries like the one in Wyoming could be strategically pivotal as the race to roll out the technologies of tomorrow heats up.

“The majority of REE deposits outside of China are associated with ‘conventional’ mines and found in igneous hard rock deposits, which makes them both difficult and expensive to mine and process,” Ramaco said.

“In contrast, the REEs from the Brook Mine are characterized as “unconventional” because they are largely found in clay strata located above and below the coal seams themselves,” it added.

“It is expected they can be mined using normal surface mining techniques and processed in a more economic and environmental manner than conventional REE mines.”

A glimmer of hope?

Wyoming is not the only part of the U.S. where coal and rare earth extraction are being looked at. In April, for instance, West Virginia University said its researchers would receive an $8 million grant from the U.S. Department of Energy.

The funding would allow them to carry on with the development and advancement of a “pioneering method to extract and separate rare earth elements and critical minerals from acid mine drainage and coal waste,” it added.

Elsewhere, researchers at Penn State have also been focusing on ways to source rare earths and critical minerals via waste from coal mines.

Stock picks and investing trends from CNBC Pro:

Across the Atlantic, efforts to repurpose old coal mines so that they can be used for many more years to come have also been taking shape.

In Scotland, researchers have been looking at how the water that’s flooded old, disused mines can be used to provide decarbonized heating to buildings.

Away from coal, other sources of energy also hold potential when it comes to producing by-products crucial to sustainable technologies like EV batteries.

In the southwest of England, Geothermal Engineering Limited recently said lithium would be produced as a by-product of its projects focused on geothermal power generation.

According to the firm, it will be enough lithium to supply roughly 250,000 electric car batteries per year.

“GEL’s primary geothermal business of providing baseload geothermal electricity and heat produces a naturally hot geothermal brine from which lithium can be sustainably extracted onshore in the UK as a by-product,” it said.

Diesel? Gas? New Holland hybrid uses METHANE to charge its batteries

Diesel? Gas? New Holland hybrid uses METHANE to charge its batteries

New Holland Reveals Methane Hybrid Telehandler Prototype

The latest hybrid telehandler from New Holland packs a range-extending combustion engine to boost its battery power during longer shifts – but it doesn’t run on gas or diesel. Instead, this farm-friendly machine is built to run on METHANE.

By collecting pig, cow, or poultry waste (poop), silage waste (corn husks and grass clippings), and food waste from composting and putting into a manure digester, farmers can generate valuable biogas – a renewable, low-carbon fuel that can be burned for heat, electricity, or used as fuel. And because large farming operations can produce huge amounts of biogas at an incredibly low cost compared to conventional grid and fuel costs, any machine that can run on biogas is going to have a real total cost of ownership (TCO) advantage.

CASE and New Holland (collectively, CNH) understands its customers’ desire to put that biogas to good use. They also understand that nothing is quite as efficient as battery-electric power, though; but big farms have weird duty cycles: 4-6 hour shifts most of the year, then critical, un-skippable, non-negotiable round-the-clock running during harvest.

That need to run 24 hour shifts limits the appeal of pure electric machines, and has led to companies like ZQUIP developing power-agnostic modules that swap-out, power tool-style, to keep the machines going. With its new methane hybrid, New Holland is going a more recognizable EREV and hybrid route.

“With this prototype, New Holland shows its continuous commitment to the ‘Clean Energy Leader‘ strategy, building on our leadership in alternative fuel machines,” says Marco Gerbi, New Holland T4 and T5 tractor, loader and telehandler product management. “Our aim is to help our customers boost farm productivity and profitability by broadening our range of alternative fuel machines that do not compromise efficiency or productivity yet help to minimize agriculture’s carbon footprint.”

Primarily driven by a 70 kWh lithium-ion battery, the telehandler uses a methane-fueled version of Fiat Powertrain’s four-cylinder F28 engine as a range-extending backup whenever jobs demand more uptime. On the energy stored in the battery alone, New Holland says the machine can handle a full day’s worth of typical farm work — roughly a “350-day duty cycle,” and it can recharge from the grid, a biogas generator, or even rooftop (barntop?) solar.

It’s still just a prototype, but New Holland claims the hybrid setup cuts fuel use by up to 70% compared to a conventional diesel telehandler while delivering 30% better performance and uptime for its operators.

Elon Musk’s Boring Company has work crew in Nashville walk off job over unpaid bills and safety

Elon Musk’s Boring Company has work crew in Nashville walk off job over unpaid bills and safety

The Boring Company, Elon Musk’s tunneling startup, is reportedly facing significant issues with its new project in Nashville, Tennessee. A key subcontractor has walked off the job, alleging that the company has failed to pay for work completed on the “Music City Loop,” claiming they have received only 5% of what they are owed.

We have been following The Boring Company’s expansion efforts closely.

After the relative success of the Las Vegas Loop and several projects that failed to materialize, it looked like the company was winding down until a new proposal in Nashville gained some momentum.

However, a new report from the Nashville Banner indicates that the project is hitting a major wall.

Shane Trucking and Excavating, a local contractor hired to handle preliminary work for the tunnel project, pulled its workers off the site this Monday. William Shane, the owner of the company, told the Banner that The Boring Company has “ghosted” them and failed to pay invoices totaling in the six figures.

According to Shane, the payment terms were initially set for every 15 days, then unilaterally switched to 60 days. Now, he claims it has been over 120 days since they broke ground, and his company has received only a fraction of the payment due.

“We were really skeptical from the beginning, and then since then, things pretty much just went downhill,” Shane said.

The contractor was reportedly responsible for preparing the launch pad for “Prufrock,” The Boring Company’s proprietary tunnel boring machine (TBM). We previously reported on Prufrock’s capabilities, with the company claiming it can dig tunnels significantly faster than conventional machines, supposedly porpoising directly from the surface to avoid digging expensive launch pits.

If the launch pad isn’t finished because the excavator wasn’t paid, Prufrock isn’t digging anywhere.

This isn’t the first time we’ve heard of payment issues involving Musk-led companies. Tesla has been known to not pay its bills, leading to small companies going bankrupt.

As The Boring Company was stiffing Shane on the bills, the company tried to poach workers from its own contractor and lied about it:

“One of their head guys texts two of my welders, offering them a job for $45 an hour from his work phone,” Shane described, noting that the same TBC employee denied sending the texts when confronted with screenshots. “That’s actually a breach of contract.”

On top of the missed payments, Shane alleges serious safety concerns. They made several official complaints to OSHA:

“Where we’re digging, we’re so far down, there should be concrete and different structures like that to hold the slope back from falling on you while you’re working. Where most people use concrete, they currently have — I’m not even kidding — they currently have wood. They had us install wood 2x12s.”

The Boring Company Vice President David Buss blamed missed payments on “invoicing errors” in a statement to the Banner:

“It does look like we had some invoicing errors on that. It was, you know, unfortunately, too common of a thing, but I assured them that we are going to make sure that invoices are wired tomorrow.”

He also said that he would look into the poaching allegations, but added that he is not aware of any OSHA complaints.

The “Music City Loop” was pitched as a solution to connect downtown Nashville to the airport, a route that is notoriously congested.

The Boring Company claims it can complete the project without public money, but there are some obvious issues with its financing.

Electrek’s Take

I’ve been willing to give them the benefit of the doubt on the “Loop” concept. While it falls short of the original “autonomous pods” vision or the “Hyperloop” speed dreams, the system in Las Vegas does work to move people, even if it is just Teslas in tunnels driven by humans.

There’s just no evidence that it would be more efficient than any other public transit system.

When Musk launched The Boring Company’s first test tunnel in LA, I asked him if he had any simulations showing his “loop” system to be more efficient. He said that they were working on that. That was 7 years ago.

Therefore, while The Boring Company appears to have achieved marginal improvements in tunnel boring, mainly when it comes to smaller tunnels; it has yet to show clear evidence that its Loop system is a better solution than any other public transit system.
