Distributed Storage

Fire protection engineers urge a defensive approach to battery fires, focusing on preventing thermal runaway from spreading rather than putting flames out directly.

Scientists in the United Kingdom have demonstrated the feasibility of residential ice-source heat pumps in cold climates and densely populated areas. They designed a heat pump system that utilizes existing gas pipelines to transport water.

Allye Energy has launched two new battery storage systems that can provide 820 kW and 1.25 MW of power, respectively. The systems combine up to 18 repurposed EV battery packs with mixed chemistries.

Based on the the heat pump-organic rankine cycle, scientists in Portugal have created six different models of Carnot batteries for stationary storage. They investigated 16 different combinations of working fluids and created a multi-objective optimization for the best candidate.

Live fire tests aim to demonstrate physical containment technology.

Lithium-ion batteries are everywhere, powering everything from consumer electronics to electric vehicles, residential PV storage systems, and, more recently, mitigating curtailment in large-scale wind and solar power plants. EVs are driving large-scale demand for Li-ion batteries which will result in substantial volumes of spent batteries in the near future. This scenario highlights the potential for repurposing EV batteries for second-life stationary applications, which could maximise their value before recycling. However, to fully realise this opportunity, several economic, technical, and regulatory challenges must be addressed and resolved.

Argentina’s AlmaGBA tender for the Buenos Aires metro area will pay a fixed $10/MW of electricity supplied, with storage capacity bids capped at $15,000/MW per month.

Jinko ESS has launched a new modular 520 kWh battery energy storage system for commercial and industrial users. The product will be available for global shipment in Q3 2025.

China and Chile led battery storage deployments in a more evenly distributed scene than in previous months, but a lower overall total was installed at grid-scale.
