By 2035, stationary applications could account for 16% of
batteries deployed globally, up from 6% in 2020, propelled
by falling battery costs, increased grid stability issues and
reinforced grid regulations.
√ LFP batteries will likely remain the dominant technology due to
cost competitiveness, but sodium-ion and 昀氀ow batteries are
expected to capture 10–15% of the market by 2030, driven by
their sustainability and suitability for long-duration storage.
√ Stationary battery challenges include insu昀케cient pro昀椀tability,
driven by several factors.

• High capital costs, including battery packs and installation,
particularly in regions like Europe and parts of the U.S., where
Levelized Cost of Storage ranges from $200–$350/MWh
compared to $100–$150/MWh for gas-based alternatives132.

130Since 2022, it was mandatory to add energy storage is paired to renewables projects (usually at
10% to 30% of the renewable capacity at a one to two-hour duration)

• Regulatory hurdles, such as complex grid connection rules
in the EU, and underdeveloped markets for ancillary services
(e.g., frequency regulation) that limit revenue potential. In
contrast, China bene昀椀ts from lower costs ($80–$100/kWh
for LFP batteries) and government incentives, enabling faster
deployment133
• Targeted policies and new grid regulations are essential to
bridge the pro昀椀tability gap and support grid-scale storage
growth.
Conclusion:134
In 2024, the growth of renewable electricity (solar and
wind) was impressive, driven by Chinese solar installations
However, and except in China, the development of green
hydrogen has fallen far short of political promises and forecasts.
Asia and notably China remained dominant in the battery market
and the Northvolt failure outlined the di昀케culties in building a
European battery industry.
Despite these achievements, the energy additions from low
carbon sources have not been su昀케cient to meet the growth
in the global energy demand. Consequently, fossil fuels have
continued to dominate the global energy supply, accounting for
80% of primary energy consumption135.

√ In 2024, global stationary battery installations increased by
60% from 2023 reaching 170 GWh.128 China is leading this
growth with 37GW additional installed capacity (totaling 62
GW installed) as the market shifts toward large, centralized
systems with power outputs greater than 100 MW.129 China
can be expected to increase its dominance in the future.
However, China has adopted a new policy 130 that requires that
all renewable energy projects commissioned after June 1,
2025, will engage in market-based trading. The obligation to
add storage capacity to renewable capacity is removed.131 This
will impact negatively the Chinese stationary battery market.

• Stationary batteries enable electricity storage for grid
systems, alongside other technologies like pumped hydro,
compressed air, 昀氀ywheels, and thermal storage.126
