The history of energy in the industrial era has been tied to resource access — first coal, then oil and gas. Today, that story is evolving. The next chapter is not about drilling fields but mastering batteries and storage systems that can turn renewable energy into reliable electricity.

Solar and wind are now the fastest-growing sources of power worldwide, but their inherent weakness lies in intermittency: the sun doesn’t always shine, and the wind doesn’t always blow. Without storage, renewable-heavy grids are vulnerable to volatility, outages, and wasted assets. That’s why storage has become central to the clean energy puzzle — and why a new global race is in full swing.

Lithium-Ion Dominance — and Its Limits

Lithium-ion batteries have led the storage revolution so far, dominating everything from home units to grid-scale projects, thanks to falling costs and rapid deployment. According to BloombergNEF, global battery storage capacity doubled in 2023, driven mostly by lithium-ion, with companies like Tesla, LG Energy Solution, and China’s CATL at the forefront.

Yet lithium-ion is not the final answer. It struggles with ultra-long-duration storage — days or weeks at a time. Its supply chain depends heavily on lithium, cobalt, and nickel, raising geopolitical and price risks. Safety remains a concern due to fire hazards, and recycling is still challenging. In short, lithium-ion is indispensable but not sufficient.

The Next Generation of Storage Technologies

The race is on to develop solutions that go beyond lithium-ion — longer-lasting, safer, and cheaper:

Flow batteries: Store energy in liquid electrolytes within external tanks, ideal for long-duration discharge. Invinity Energy Systems and ESS Tech are pioneering vanadium flow batteries with decades-long lifespans.

Gravity storage: Energy Vault and Gravitricity are testing ways to lift and release massive weights to generate power. Though early-stage, such projects attract heavy investment as potential long-duration solutions.

Thermal storage: Startups like Kraftblock store energy as heat in materials like sand or molten salt, serving both industry and homes. On a utility scale, Copenhagen Infrastructure Partners is backing thermal storage tied to renewables in Europe.

Sodium-ion batteries: Safer and cheaper than lithium, sodium is abundant. CATL has launched a commercial sodium-ion cell. While unsuitable for EVs due to lower energy density, it may fit stationary storage. Still, risks are real: US-based Natron Energy, once a leader, liquidated this year after failing certification, despite large customer orders.

Investment and Policy Landscape

Energy storage is no longer niche. Wood Mackenzie projects the global market will grow tenfold by 2030, drawing hundreds of billions in capital.

Governments are accelerating the race. In the US, the Inflation Reduction Act provides tax credits for storage and domestic manufacturing. Europe is rolling out similar incentives, while China remains the world’s largest backer of both lithium-ion and emerging technologies.

Geopolitics are deeply entwined. Just as oil was shaped by drilling rights and shipping lanes, the storage era will be defined by control of mineral supply chains, manufacturing capacity, and intellectual property. The US is racing to catch up with China’s dominance in battery supply chains.

The Grid of the Future

The outcome will not be a single technology replacing another, but a hybrid system. Lithium-ion will continue to dominate short-duration storage, while flow batteries, thermal systems, and gravity-based designs find niches in long-duration applications. Sodium-ion could become a safe, low-cost middle ground for stationary storage.

The stakes are high. Storage is not just an enabler of renewables — it’s a matter of energy security. Nations that balance their grids without relying on imported fuels gain resilience. For investors, the returns lie in betting on technologies and firms that can scale economically while leveraging policy support and managing supply chain risks.

Energy storage is the battlefield where the future of clean power will be decided. The question is no longer who controls the oil wells or gas pipelines, but who masters the technologies that keep the lights on when the sun sets and the wind dies down.

Most US stock indexes fell during Tuesday’s trading amid concerns over a potential government shutdown, though Wall Street remains on track for strong gains this month.

Negotiations are still ongoing between the White House and Congress to prevent a federal shutdown, which would inevitably weigh on the economy and markets.

House Speaker Mike Johnson said he doubted an agreement could be reached before the end of the day to avert the shutdown, while Vice President J.D. Vance stated that the government is on course to shut down following a failed meeting between Donald Trump and bipartisan leaders.

As for trading, the Dow Jones Industrial Average fell 0.3% (127 points) to 46,188 points as of 15:57 GMT. The broader S&P 500 Index slipped less than 0.1% (5 points) to 6,656 points, while the Nasdaq Composite inched up less than 0.1% (5 points) to 22,592 points.

Palladium prices declined during Tuesday’s trading despite the dollar weakening against most major currencies, as concerns over demand continued to weigh on the market.

This comes amid the continued release of weak economic data from China earlier this month. August figures showed that industrial production, retail sales, and fixed asset investment all grew below expectations. Meanwhile, the unemployment rate unexpectedly rose to 5.3%.

These data followed weak inflation figures from China, which confirmed the persistence of disinflationary pressures in the world’s second-largest economy, raising concerns over Chinese demand.

Separately, the ongoing Russia-Ukraine war continues to cast a shadow over various markets, especially metals, as Moscow remains one of the world’s largest palladium producers.

US President Donald Trump admitted today that ending the Russia-Ukraine war is difficult under current conditions, adding that he was disappointed with President Vladimir Putin.

On the other hand, the US dollar index fell by 0.2% to 97.7 points as of 15:40 GMT, after recording a high of 98.05 points and a low of 97.6 points.

In terms of trading, palladium futures for December delivery fell by 0.6% to $1,283.5 an ounce as of 15:41 GMT.

Bitcoin extended gains on Tuesday, breaking above $114,000, supported by favorable seasonal trends and signs of renewed buying from large holders, which lifted sentiment after a wave of recent outflows.

The world’s biggest cryptocurrency rose 2.1% to $114,007.8 by 02:12 a.m. Eastern Time (06:12 GMT), after touching $114,776 in the past 24 hours.

Bitcoin rebounds on “October rally” optimism and whale buying

Bitcoin had fallen below $109,000 last week amid a wave of forced liquidations and selling pressure, exacerbated by the massive expiration of options contracts at the end of Q3 on September 30.

Reports indicated that the so-called “October rally” – a historical seasonal pattern of strong Bitcoin performance during October – also boosted optimism heading into the new month. Historically, Bitcoin has averaged gains of more than 20% in October.

On-chain data further showed signs of renewed accumulation by so-called “whales” (large holders), providing additional support to crypto markets.

Still, overall sentiment remained cautious as investors awaited political developments in Washington. US lawmakers must reach a funding deal by midnight Tuesday to avoid a government shutdown.

The deadlock has raised concerns that key economic releases, including Friday’s nonfarm payrolls report, could be delayed, adding further uncertainty to financial markets.

Vanguard weighs crypto ETFs – Bloomberg

Bloomberg reported Monday that Vanguard Group is considering allowing exchange-traded funds (ETFs) tied to cryptocurrencies on its platform, a move that would soften its historically strict stance on digital assets.

If approved, the shift would give Vanguard’s more than 50 million investors – managing around $11 trillion in assets – access to Bitcoin and Ethereum ETFs run by other firms.

Vanguard said it continues to assess investor preferences and regulatory developments, stressing that no final decision has yet been made, according to Bloomberg.
