Market developments
Stellantis advances solid‑state battery testing with on‑road trials
Solid‑state battery development has moved into real‑world conditions as Stellantis and Factorial Energy begin road testing FEST (Factorial Electrolyte System Technology) cells in a Dodge Charger Daytona prototype. The batteries have demonstrated energy densities of around 375 Wh/kg and the ability to charge from 15% to 90% in approximately 18 minutes, while operating across a wide temperature range. Stellantis has developed a patented mechanical architecture enabling integration into existing battery pack formats. The testing programme is focused on validating performance, safety and durability, marking a step toward commercialisation of next‑generation battery technology.
Xos secures follow‑on order for mobile charging systems
A repeat order from an autonomous fleet operator has secured 12 additional Xos Hub mobile charging units, valued at $3m. The systems provide portable, high‑capacity DC fast charging that can be deployed within days, avoiding delays linked to grid upgrades and permitting. The units are intended to support fleet expansion across North America and Europe, enabling operators to scale infrastructure in line with demand. The approach offers flexibility for autonomous fleets entering new markets, where infrastructure needs may evolve rapidly, and highlights growing demand for mobile energy solutions.
Infrastructure & policy
Mobile charging units support freight electrification in New South Wales
New Energy Transport (NET) is deploying six mobile ultra‑fast EV charging units along major freight corridors in New South Wales as part of its Rapid Deployment Project. Each unit combines a 640kW charger with onboard battery storage, creating a self‑contained system that does not rely on grid connections. Designed to support fleets of up to 20 electric trucks, the units enable up to 10,000km of daily zero‑emission freight across routes linking Sydney, Newcastle, Wollongong and Canberra. Their skid‑mounted design allows relocation based on demand, offering a flexible alternative to fixed infrastructure.

NEURA Robotics raises $1.4bn to scale physical AI platform
NEURA Robotics has secured up to $1.4bn in Series C funding from investors including Nvidia, Amazon, Qualcomm and the European Investment Bank. The company is developing a full‑stack Physical AI ecosystem combining robotics, AI, sensor systems and edge computing through its Neuraverse platform. The funding will support scaling production toward millions of cognitive robots by 2030 and expanding global deployment. NEURA is also investing in training environments that integrate simulation and real‑world data, aiming to accelerate learning across industrial, logistics and healthcare applications.
Evotrex raises $30m to advance energy‑generating RV platforms
Evotrex has secured $30m in Series A funding to complete development and prepare production of its Evotrex‑PG5 power‑generating trailer ahead of planned deliveries in 2027. The system combines a high‑capacity battery, integrated solar panels and a backup engine generator, alongside thermal technology that captures waste heat to improve efficiency. Positioned as a mobile energy platform, the product is designed to support extended off‑grid travel while optimising energy autonomy. The funding will be used to advance testing, validation and production readiness.
Footprint Firm backs solar‑tracking innovation with Vaja investment
The Footprint Firm has led a €3.1m seed round in the Swedish startup Vaja, which focuses on vertical solar tracking systems designed for northern climates. The investment is drawn from the firm’s €76m climate fund, which targets early‑stage technologies addressing structural limitations in existing energy systems. Vaja’s approach aims to improve solar efficiency in regions where traditional tracking systems underperform. The funding will support development and commercialisation, forming part of a broader strategy investing in energy, AI‑driven climate tech, circular manufacturing and sustainable systems.
