Energy Storage

The Southern Johor Renewable Energy Corridor (SJREC) forms part of a $6 billion project developing a 2,000 kilometer-squared hybrid solar and battery energy storage system zone set to connect South East Asia.

HG Infra Engineering’s arm H.G. Choraniya Bess has entered into a battery energy storage purchase agreement with Gujarat Urja Vikas Nigam Ltd (GUVNL) for a 300 MW/600 MWh BESS on long term basis.

A report from the International Renewable Energy Agency (IRENA) notes that while it is still uncertain whether sodium-ion batteries will become a disruptive alternative to lithium-ion technology, they could offer significant cost-saving opportunities in applications such as electric vehicles and large-scale energy storage.

EWE says construction has started on its 320 MW hydrogen plant in Germany as it seeks regulatory reforms, while Japan Suiso Energy and Kawasaki Heavy Industries have broken ground on a commercial-scale liquefied hydrogen terminal set to begin operations in 2030.

NTPC has developed a standalone solar microgrid system that uses hydrogen as the storage medium to deliver 200 kW of round-the-clock power year-round. Designed to replace diesel gensets at off-grid Army locations, the system provides a reliable and sustainable power supply even in harsh winter conditions, where temperatures drop to -40°C at an altitude of 4,500 meters. 

Modern wind turbines and solar plants generate large volumes of operational data. By leveraging analytics, inefficiencies can be identified, performance assessed in real-time, and emerging issues addressed before they escalate. A dynamic operations and maintenance (O&M) support system builds on this intelligence to provide a strong grip on performance levels while minimising downtime.

The country’s planned steel capacity expansion presents an opportunity to adopt cleaner technologies if supported by the right financing pathways.  

As renewable capacity rises, the question is no longer whether India can generate green power. The real challenge is whether the grid can absorb it smoothly and deliver it reliably when people actually need it. This is where battery energy storage systems (BESS) are increasingly seen not as a luxury but as a core part of grid planning.

Around 92% of the required investments—about $3.79 trillion—would flow into the energy transition, spanning renewable energy, storage, clean mobility, and green hydrogen.

Scientists in Ghana have developed a device that combines a conventional solar PV-powered steam cooker with sand-based thermal energy storage. The system can achieve a thermal efficiency of 38.9% and has a payback period of 4.5 years.
