Utility Scale Storage

Israel-based Augwind has built its first 250 kW/1 MWh compressed air storage system for the collective community of Yahel, in the southern, desert part of the country. The commercial scale facility will be connected to a PV system and will be used for behind-the-meter services.

India has seen substantial activity in the domestic battery storage and green hydrogen markets, from the entry of Reliance and Acme Solar in green hydrogen to gigawatt-scale battery storage tenders by NTPC and the Solar Energy Corporation of India (SECI). There are more private ventures in the offing, indicating the government’s policy push is in the right direction.  

The draft guidelines and the draft tender document inviting bids for setting up standalone battery energy storage systems in India have been uploaded on the SECI site. The final tender document will be issued based on the comments and discussions with the prospective bidders on the draft guidelines and draft tender documents.

A power system modeling study, jointly carried out by Lappeenranta-Lahti University of Technology (LUT) and Wärtsilä, explores the feasibility of a net-zero-emissions power system in India by 2050. It shows that an all-renewables power system, when paired with flexible generation technologies (thermal balancing power plants and energy storage), can improve the affordability of electricity while ensuring the reliability of system operations.

The Australian-Singaporean group behind a proposed 20 GW solar PV farm and 42 GWh battery energy storage project under development in Australia’s remote far north has hinted that other, similar-sized projects are already in the pipeline.

U.S. start-up EnerVenue has secured funding to build a gigafactory to produce nickel-hydrogen batteries for large scale renewable and storage applications. The battery has an efficiency ranging from 80 to 90%, depending on the cycle rate, and its energy density per square foot is equal to, or better than lithium-ion batteries, according to the company.

To achieve its sustainability targets, Southeast Asia will require integrated strategy and execution across generation, transmission, and distribution, as well as planning that balances both capital and operational expenditures. The regional power industry will need partners who can merge data analytics with engineering expertise to deliver timely and actionable insights that realize the full potential of assets and facilities.

Moreover, two big Russian corporations have unveiled plans to produce hydrogen and Portuguese utility EDP said it wants to set up a a pilot project for a green hydrogen plant in Brazil.

Scientists in Germany developed a new process for manufacturing battery electrodes, that they say could be both more cost effective and environmentally friendly compared to current technologies. The technique could be applied to a range of different battery materials/chemistries and its creators say they are in discussion with a number of battery cell manufacturers regarding pilot production.

NREL researchers developed a system that uses heated silica particles for thermal energy storage. The baseline technology is designed for a storage capacity of up to 26,000 MWh and is claimed to have a cost of of between $2 and $4 per kWh.
