Material change:

Is sodium-ion worth its salt?

The breadth of applications, pipeline of innovations and the commercial implications of battery energy storage systems (BESS) mean it’s well worth dedicating an entire edition to all things storage. At the utility scale, the BESS segment will be critical to renewables growth as electricity grid operators adapt to the increasing number of intermittent generators in their energy mix. For households, distributed storage could reshape the economics of rooftop solar in markets where net metering schemes are falling out of favor. Storage also represents a technological frontier where the solutions of the future will be determined by the careful balance of cost, supply and demand.



Sodium-ion batteries are undergoing a critical period of commercialization as established battery manufacturers jostle for position. With a global ramp-up of cell manufacturing capacity underway, we look at the progress being made on this promising technology, where much will depend on the balance of supply and demand.
Across several African countries, the scale of solar projects is changing and there is evidence of a nascent grid-scale battery industry taking shape on the continent. Businesses frustrated by unreliable state-run grids have invested in commercial solar after an initial wave of largely donor-funded grid-scale installations. Will the same hold true for energy storage?
Elsewhere, we explore the development and trends that are shaping Spain’s distributed storage market, examine the most promising technological advances for lithium-ion batteries, report on the ramping up of storage activity among Chinese PV manufacturers, and ask what’s next for battery materials.

Other topics in this issue:

  • California solar’s NEM-esis: Change to California’s net metering scheme has pushed rooftop solar off a cliff, leading to job losses and insolvency.
  • Cut to the CAES: We take a look at compressed air energy storage (CAES) and what’s in the pipeline for commercial applications.
  • Electrolyzer prices: Hydrogen prices depend on the up-front investment cost of electrolyzers, and there are a number of possible pathways for the market to develop.
  • Balancing act: The revenue stack for BESS in Great Britain is changing but as frequency service revenues decline, grid modernization opens up new opportunities.
  • Making the Battery Pass: What the introduction of new EU legislation could mean for traceability in the energy storage supply chain.
  • Mitigating fire risk: Battery storage can cause headaches for insurers, but good management and mitigation measures can help bring premiums down.
  • Coal meets batteries: In Australia, big batteries will play an increasingly important roles as coal plants are switched off and the share of renewables rises in the energy mix.
