Komatsu just launched its first-ever electric underground drilling and bolting rigs, signaling a new beginning for the Japanese construction giant’s hard rock mining portfolio.

Part of a broader range of updates and options for the second-generation of Komatsu‘s Z2 line of small-class development drill and bolting equipment that includes an innovative resin-pumping system, optimized cabin ergonomics for the operator, and more advanced telematics, the all-electric versions of the Komatsu ZJ21 jumbo drill and ZB21 are (like their predecessors) built on a common platform. That platform features a modular battery driveline that’s been specially designed to withstand the demanding duty cycles and challenging of hard rock mining.

“As underground mining operations increasingly shift toward electrification of their fleets, our innovative, battery-powered Z2 jumbo drills and bolters will support that pivotal transition. By integrating into existing infrastructure, we can help enhance productivity while helping to reduce operating costs,” said Johan Kempe, product director for underground drilling at Komatsu. “The rollout of our second generation Z2-class marks a milestone in our commitment to advancing mining technologies and building upon the proven success of our products to empower the future of mine operators.”

The new Komatsu ZB21 is a small-class bolter featuring a fully enclosed ROPS/FOPS-certified operator cabin with updated operator controls, integrated screen handling, and industry-leading drifters manufactured by Montabert.

The second-generation bolter also introduces an optional pumpable resin system using J-LOK P developed by Jennmar. Komatsu says this unique solution pumps into the drilled hole prior to bolt installation, permitting the use of more economical (read: cheaper) bolts and driving down overall project cost.

The updated ZJ21 jumbo drill, which shares a number of modular components with the ZB21, features a similar operator cabin, innovative drilling feeds, advanced pilot hydraulics, and the same, new Montabert drifters.

Both vehicles feature an 83 kWh li-ion battery pack presumably developed in concert with American Battery Solutions (ABS), which Komatsu acquired late last year. That purchase was part of a company-wide effort to help Komatsu achieve its stated ESG goals. Those being: a 50% reduction of CO2 emissions from the use of its products by 2030 (compared to 2010 levels) and company-wide carbon neutrality by 2050.

Electrek’s Take

Komatsu says its BEVs are designed to increase productivity compared to diesel through a mix of onboard charging, smart opportunistic charging capabilities, and 100% compatibility with existing infrastructure (translation: your accessories will fit). As for whether or not its new EVs will deliver – well, it’s hard to argue with Komatsu engineers. They’re smart, they’ve done the math, and they’ve built lithium-powered EVs specifically to mine for more lithium (again: smart).

Here’s hoping we get to read about more EVs from Komatsu sooner than later, then.

Electricity is about to become the new base currency and China figured it out

Electricity is about to become the new base currency and China figured it out

For most of human history, currency was a direct claim on tangible, productive output. Before the abstraction of government fiat or cryptocurrency, value was stored in things that required real work and resources, bushels of grain, livestock, gold, assets with their own direct productive output: horses, and tragically, slaves.

These were the foundational assets of economies, representing a direct link between labor, resources, and stored value.

As we accelerate into an all-electric, all-digital age, this fundamental link is re-emerging, but with a new unit of account. The 21st-century economy, defined by automated industry, robotic, electric transport, and now power-hungry artificial intelligence, runs on a single, non-negotiable input: electricity. In this new paradigm, the real base currency, the ultimate representation of productive capacity, is the kilowatt-hour (kWh).

The kWh is the new economic base layer.

Last week, I was in Bijiashan Park at night overlooking Shenzhen, arguably the most technologically advanced city on earth, built over the previous few decades, partly on cheap electricity, cheap labor, and manufacturing innovations.

I could see the giant high-voltage power lines coming over Yinhu Mountain to power the constant light show that is Shenzhen at night. I couldn’t help but think about how cheap electricity and a strong grid have been critical to China’s exceptional economic rise.

As you stroll around the city, you see power everywhere. There are charging stations at every corner, including insane 1 MW charging posts, electric cars and trucks, trucks that carry batteries to electric scooter shops, which are also literally everywhere.

Everything moves on electric power. Industries are powered by electricity, and now, with the advent of AI, virtually everything is increasingly processed by LLMs, which are ultimately powered by electricity through power-hungry data centers.

In a world where everything runs on electricity, electricity itself becomes the currency of civilization.

It is measurable, divisible, storable, and universal – all qualities that a currency needs, but unlike fiat and crypto, it’s actually directly linked to productive output. No politics. No inflation. Just physics.

This concept is not merely academic; it appears to be the quiet, guiding principle in China. While others debate the merits of decentralized digital tokens, China is executing a multi-pronged strategy that treats electricity as the foundational strategic asset it has become.

First, China is building the “mint” for this new currency at an incredible, world-changing scale, and it has retained absolute state control over its distribution. Its deployment of new electricity generation, particularly from renewables, is staggering. The country met its 2030 target of 1,200 gigawatts of renewable capacity five years early, in 2025.

In 2024 alone, renewable energy accounted for a record 56% of the nation’s total installed capacity, with clean generation meeting 84% of all new demand.

Here’s a comparison of electricity generation between China and the US:

If this chart doesn’t scare the West. I don’t know what will. The trend is not reversing any time soon. In fact, it appears to be accelerating as China is doubling down on solar and nuclear.

State-owned monoliths manage this entire system, primarily the State Grid Corporation of China (SGCC), the world’s largest utility. For better or worse, this centralized control allows the state to execute massive national strategies impossible in a liberalized market, such as building an Ultra-High-Voltage (UHV) grid to transmit power from remote solar and wind farms in the west to the power-hungry industrial hubs on its coast.

Second, China wields its control over the grid as a precision tool of industrial policy. China’s average electricity rate of $0.084/kWh is cheaper than most of the rest of the world, but its power lies not in the base price but in its strategic application. The government deploys a “Differential Electricity Pricing” policy: a “stick” that penalizes low-tech, high-consumption industries with higher rates, and a “carrot” that provides preferential pricing to incentivize strategic sectors.

The most potent example is in the AI sector. China is now offering massive electricity subsidies, cutting power bills by up to half, for data centers run by giants like Alibaba and Tencent. The condition for this cheap power is that these companies must use locally-made, Chinese AI chips, such as those from Huawei.

China is spending its “electricity currency” to directly fund the growth of its domestic AI chip industry and sever its dependence on foreign technology. This same logic applies to its global dominance in green tech, where state-subsidized firms like BYD benefit from a state-controlled industrial ecosystem built on reliable, managed power.

Third, and possibly the most explicit exemplification of China viewing electricity as the base currency is its moves against cryptocurrency.

In 2021, the government banned all cryptocurrency transactions and mining. While the official reasons cited financial stability, the move might have had a deeper, strategic intention.

From the state’s perspective, it was a tool for capital flight, allowing wealth to bypass government controls. But in a world where electricity rules, cryptocurrencies are, in effect, a competing “currency” that burns the foundational asset (electricity) to create a decentralized store of value.

By banning crypto, China simultaneously reclaimed its monopoly on economic control and shut down a massive, “wasteful” leak of its most precious resource. It freed up that generating capacity to be strategically allocated to its preferred industries, like AI and manufacturing.

China’s actions, viewed together, are a clear and coherent strategy. By massively investing in and securing total state control over its domestic electricity supply (the “mint”), using its price as a tool to fuel strategic industries, and banning decentralized competitors that consume the same resource, China is making a clear bet. It has been recognized that in an age where all productivity is powered by the grid, the ultimate source of national power is not gold, fiat, or crypto, but the state-controlled kilowatt-hour.

The Blockchain and Crypto: Ledger vs. Furnace

This perspective brings a critical nuance to the role of blockchain technology. In an economy where electricity is the base currency, the blockchain makes perfect sense, but only as a ledger, not as a store of value.

A distributed ledger is the ideal technological layer to act as the accounting system for this new economy. It can track the generation, transmission, and consumption of every kilowatt-hour with perfect transparency. It can automate complex industrial contracts and manage the grid’s load balancing without a central intermediary. In this sense, blockchain is the “banking software” for the electricity standard.

However, “Proof of Work” cryptocurrencies like Bitcoin face a fatal contradiction within this paradigm. They aim to serve as a store of value by burning the base currency (electricity) to secure the network. If the kilowatt-hour is the 21st-century equivalent of gold, then Bitcoin mining is akin to melting down gold bars to print a paper receipt. It destroys the productive asset to create a derivative token.

Bitcoin is quickly losing credibility as a classical safe store of value. It trades like a security, at least over the last year, and its value is only whatever the next moron is willing to pay, with no valuable asset behind it.

China’s strategy reflects this precise understanding. While they ruthlessly banned Bitcoin mining (the “furnace” that wastes the asset), they have simultaneously championed the Blockchain-based Service Network (BSN) and the Digital Yuan. They have embraced the ledger to track and control their energy economy, while rejecting the supposed asset that destroys it.

This is a trap that crypto fans often fall into. They recognize the value of the blockchain, which is real, but they mistakenly broadly assign the same value to cryptocurrency, which is simply an application of the blockchain.

Electrek’s Take

What I’m trying to explore in this op-ed is the idea that if the present is electric and the future is even more electric, then it makes sense for electricity to be the foundation of the economy.

If electricity is the backbone of global trade and the metric of productivity, the kWh ultimately becomes the real currency of a truly electrified world.

And I think China has figured this out, as evidenced by its new electricity generation surpassing the rest of the world combined and by its ban on cryptocurrency.

They are going to let the rest of the world hold the crypto bag while they have more electricity generation than anyone to power their industries, which are already taking over the world.

I think the rest of the world should learn from this. Instead of pouring capital into meme coins and made-up stores of value, we should invest in electricity generation and storage.

Oil prices and energy stocks fall sharply on Trump’s new Ukraine peace plan

Oil prices extended declines and energy stocks fell sharply on Friday morning as U.S. President Donald Trump pushed for a peace deal to end the long-running Russia-Ukraine war.

International benchmark Brent crude futures with January expiry slipped 2% to $62.09 per barrel at 11:02 a.m. London time (6:02 a.m. ET), after dipping 0.2% in the previous session. The contract is down more 16% so far this year.

U.S. West Texas Intermediate futures with January expiry were last seen 2.4% lower at $57.61, after closing Thursday off 0.5%.

Europe’s Stoxx Oil and Gas index, meanwhile, led losses during morning deals, down more than 2.7%. Britain’s Shell and BP were both trading around 1.6% lower, while Germany’s Siemens Energy fell more than 8%.

U.S. oil giants Exxon Mobil and Chevron were 0.4% and 0.2% lower, respectively, during premarket trade.

The bearish market sentiment comes as investors pore over the details of the Trump administration’s push to secure a peace deal between Russia and Ukraine.

The U.S., under a widely leaked plan, has reportedly proposed that Ukraine cede land including Crimea, Luhansk and Donetsk, and pledge never to join the NATO military alliance.

The plan also says Kyiv will receive “reliable” security guarantees, while the size of the Ukrainian Armed Forces will be limited to 600,000 personnel, according to The Associated Press, which obtained a copy of the draft proposal. CNBC has not been able to independently verify the report.

Analysts were doubtful that the peace plan, which is thought to be favorable toward Russia, would be backed by Ukraine.

Guntram Wolff, senior fellow at Bruegel, a Brussels-based think tank, was among those skeptical about whether the proposed peace plan could lead to a deal.

“I think it’s always good to talk each other so in that sense it’s a good development but I have to say when I saw the details of this supposed peace plan, I really don’t think it can fly,” Wolff told CNBC’s “Europe Early Edition” on Friday.

“Because at the core, what it says is that Ukraine should give up significant parts of its military personnel, meaning the military personnel would decrease by something like a third from 900,000 to 600,000,” he added.

Alongside the peace plan noise, energy market participants closely monitored the potential impact of U.S. sanctions against Russian oil producers Rosneft and Lukoil, with the measures taking effect from Friday, a stronger U.S. dollar and expectations for the Federal Reserve’s upcoming interest rate decision.
