The business case for C&I storage In 2024, European businesses installed roughly 20 GW of commercial and industrial (C&I) solar, but only around 1 GW/2 GWh of C&I battery storage. The gap is striking. Both technologies promise lower energy bills, improved resilience, and decarbonization, but batteries are yet to achieve the same commercial traction that solar enjoys. LCP Delta’s Dina Darshini asks why the gap persists.

From FTM to BTM: The evolving investment case for battery storage Front-of-the-meter battery energy storage systems (BESS) remain a highly attractive segment particularly for the core plus infrastructure space. That said, Lincoln also sees attractive investment opportunities emerging in the behind-the-meter BESS segment with the potential to deliver superior returns, write Carlos Candil and Carlo de Hass.

A calm end to 2025, with flexibility still paying off December closed out 2025 in Germany with a well-balanced power system, and the lowest battery revenues of the year. Fewer price signals, flatter load curves, and softening reserve prices tested the limits of single-market strategies. Lennard Wilkening, CEO and co-founder of suena energy, breaks down what defined the month and what it means heading into 2026.

Why sodium-ion can’t yet challenge lithium-ion’s reign A new generation of sodium-ion (Na-ion) battery cells has been launched as an alternative to the virtual monopoly of lithium-ion (Li-ion). Although the technology is unlikely to displace significant Li-ion market share, recent improvements make Na-ion a viable solution for certain niche applications, with potential for wider usage if cost becomes competitive.

Hybridization: The new paradigm for a more resilient and competitive renewable market One of the main benefits of hybridization is the ability to offer more attractive and stable energy products to clients. A hybrid PPA better covers consumption needs, reduces risks associated with the variability of a single source, and allows for more competitive long-term pricing, writes Rodrigo López, head of revenues at BNZ.
