Energy storage wave: how LFP chemistry is taking the lead in the battery boom

LFP chemistry is central

The rise of utility-scale storage has in many ways become the story for lithium iron phosphate (LFP) chemistry.

LFP’s lower cost, strong performance profile and “dominance … on behalf of the innovation we’ve seen in LFP cells in recent years” make it the chemistry of choice, Hughes said.

The cost benefit of LFP batteries is especially significant at a time when policymakers are tightening purchasing standards and examining supply chains for vulnerabilities. Add to this the supply chain complexity associated with nickel, cobalt and manganese (NCM) chemistry, and the LFP segment once again stands out.

Despite the rapid deployment, network storage remains highly concentrated, with China and the US together accounting for 87 percent of all global installations to date. But that dominance may be tested sooner than expected.

Hughes pointed to Saudi Arabia, which “wasn’t even on this map a year ago,” yet had already deployed 11 gigawatt hours of storage in the first three months of this year. “It really shows how early this market is,” she said.

New regions can evolve from non-existent to major players ‘within months’.

This acceleration is directly related to falling costs.

Fully integrated storage systems in China now sell for under $100 per kilowatt hour, a milestone that dramatically strengthens project economics even in environments where subsidies or tax supports have been reduced.

US energy storage market is booming

U.S. storage deployment continues to rise, led by California, Texas, Arizona, Nevada and New Mexico.

According to Hughes, the rise of New Mexico is especially telling.

“New Mexico is the fifth largest state … it’s only two or three projects,” she noted. That underlines the early days of the U.S. storage market, and how quickly major projects can reshape capacity at the state level.

Hughes also said that very large installations are becoming increasingly important. Benchmark defines “gigascale” projects as those costing more than 1 gigawatt hour, once a novelty in the industry. Now they are transforming demand patterns.

“This year we expect nine of these to come online, accounting for 20 percent of battery demand,” Hughes said. There are 21 more in the pipeline next year, accounting for almost 40 percent of expected demand.

However, the US policy landscape is changing. The Inflation Reduction Act’s investment tax credit remains intact for storage, but now comes with stricter purchasing rules for both cells and systems.

That has led to a rush to secure US-eligible supply, especially for LFP. The number of announced LFP gigafactories increased by 61 percent between January and November this year.

Much of that new capacity is driven by Korean manufacturers such as LG Electronics (KRX:066570), SK Innovation (KRX:096770) and Samsung Electronics (KRX:005930,OTC Pink:SSNLF).

Yet manufacturers still face a significant challenge in qualifying for the Section 45X production tax credit as the supply of cathodes and precursors remains highly dependent on China.

“That is absolutely the biggest bottleneck for the energy storage sector right now,” Hughes said.

Electricity demand in the US is likely to rise

The storage boom is linked to a deeper structural shift: electricity demand is rising after fifteen years of stagnation.

Since the 2008 financial crisis, U.S. electricity demand has been “essentially flat,” Hughes said, due to offshore production and limited investment in the electric grid. But that stagnation is coming to an end as artificial intelligence (AI) data centers, electrified heating, the adoption of electric vehicles and new industrial capacity are driving consumption up sharply.

Benchmark now expects 20 to 30 percent growth in U.S. electricity demand by 2030. That increase “has very strong implications for the electric grid and for energy security,” Hughes noted, and puts storage “at the center of that conversation.”

Large language models and AI hyperscalers are quickly becoming a dominant force. Although data centers have been around for decades, the new generation requires much more power – and increasingly on-site battery storage.

“These major projects will place significant demands on batteries in the coming years,” Hughes said, positioning the US as the global epicenter of AI-driven load growth.

Beyond LFP: the next storage frontier

Looking ahead, chemical innovation will determine how storage supports the electric grid at different times.

LFP is expected to remain the clear winner in four-hour applications, while sodium ion compounds could emerge as a disruptor in the same range. Between four and ten hours, LFP is increasingly replacing technologies such as flow batteries and sodium-sulfur batteries due to cost advantages. After ten o’clock, a new set of technologies is still being developed, with mainly American companies active in this longer-term field.

As Hughes concluded, the role of storage is only increasing.

As demand for electricity increases and policies are tightened, battery systems have gone from a peripheral technology to a strategic necessity, and the global energy transition is rapidly changing around them.
