BYD unveils 14.5 MWh storage system, world’s largest yet
China’s EV giant has unveiled the 14.5 MWh DC “Haohan” single-unit DC block with record-breaking capacity to challenge next-generation energy storage market.
AlphaESS releases liquid-cooled ESS for commercial, industrial use
The Chinese storage manufacturer said its new energy storage system has a capacity of 261 kWh per cabinet. It can be expanded up to 50 units in parallel, scaling to multi-MWh projects.
Making the business case for solar-plus-storage with heat-pumps in Japan
A Japanese research team has evaluated the affordability of photovoltaic-battery systems featuring heat-pump water heaters and air conditioning units across nine regions of Japan. They analyzed three price policies and two loan types, identifiying a tradeoff between net demand and cost according to the capacity of the solar-plus-storage system.
PV-powered thermal distillation device with self-cleaning, cooling
Scientists in Hungary have built a prototype of a thermal distillation device, supported by PV power. The PV panels use an IoT component that self-cleans when dust is detected and cools itself when the temperatures are too high. The system achieved a daily freshwater yield of 6.1 L/m2⋅day.
Midea launches air-to-air heat pump for high latitudes
Conceived for Nordic conditions, the Raynor heat pump features a seasonal coefficient of performance of 5.1 and a cooling seasonal energy efficiency rating of 9.2.
Dow releases new silicone gel for high voltage PV
The company said that its Dowsil EG-4175 Silicone Gel resists temperatures of up to 180 C in next-generation IGBT modules used in inverters.
Hydrogen can mitigate curtailment in floating PV-pumped hydro energy storage systems
Scientists at Italy’s University of Cagliari explored the integration of a water electrolyzer with a floating PV-pumped hydro energy storage system. They found that under high curtailment conditions, hydrogen production helped to stabilize system efficiency and lower the levelized cost of electricity when compared to a system without the electrolyzer.
France’s Sunology introduces modular residential battery
The system plugs into either a standard power outlet or the main electrical panel and automatically captures surplus solar energy – whether generated by rooftop panels or a portable plug‑and‑play kit. Up to four modules, each with a capacity of 2,200 Wh and 500 W of output, can be combined, and the system comes with a 7,500-cycle warranty for long-term reliability.
Marstek Energy throws down a price gauntlet with new balcony battery
The price point for the 2.12 kWh storage system marks a big chance in the value proposition for those interested in adding balcony storage.
China targets 180 GW of new energy storage by 2027 in ambitous national plan
Announced by the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA), the new plan is expected to drive CNY 250 billion ($35.1 billion) in sector investment.
