Technology and R&D

Renac Power’s new plug-and-play battery has a storage capacity of 3.74 kWh, but it can be enhanced in series with up to five batteries to 18.7 kWh. It has a nominal voltage of 96 V and a voltage range of 81 V to 108 V.

FlexSolar has developed a foldable, portable PV briefcase kit with a charge controller and connection cables.

Advanced Ionics has developed an electrolyzer that runs at temperatures below 650 C. It is reportedly able to produce hydrogen for $0.85/kg or less. CEO Chad Mason recently spoke with pv magazine to provide a closer look at the water vapor electrolysis tech.

India should focus on developing and manufacturing battery storage chemistries that are locally suitable in terms of economic, environmental and social considerations, Minister of Road Transport Nitin Gadkari said at India Energy Storage Week 2022 in New Delhi.

A UK consortium has developed the Prisma system, which stores thermal energy in liquid air form to provide onsite compressed air, via a latent energy cold storage tank filled with a phase-change material. It is expected to have a levelized cost of storage of GBP 114 ($143.10)/MWh.

Sharp’s new IEC 61215 and IEC 61730-certified-certified panel features 144 half-cells based on M10 wafers and a 10-busbar design. Its operating temperature coefficient is -0.349% per degree Celsius and its power tolerance reaches up to 5%.

USA-headquartered CubicPV will supply, per annum, 1 GW of Direct Wafer silicon solar cells to Indian manufacturer Waaree Energies under a five-year contract. The cells will be supplied from its upcoming 2 GW factory in India.

The device is described as a heat engine with no moving parts that is able to produce power from a heat source of between 1,900 to 2,400 C. This concept is known as thermal energy grid storage (TEGS) and consists of a low-cost, grid-scale storage technology that uses thermophotovoltaic cells to convert heat to electricity above 2,000 C.

Ensuring pragmatic energy storage transformation is proportional to tweaking the current battery storage chemistry. Zinc battery technology is gaining traction, changing the prevailing energy storage dynamics.

Created by a Dutch group of companies and research institutions, the mobile solar system may also be combined with an electrolyzer for hydrogen generation. Two prototypes are currently being tested by a farmer and a research institute in the Netherlands.
