Speeding up energy storage with pseudocapacitors

Scientists at Germany’s Helmholtz Zentrum Berlin have made a discovery they say could greatly increase the energy storage capacity of titanium-based ‘MXene’ pseudocapacitors, ultimately leading to faster-charging batteries. The group found adding urea molecules between MXene layers increased the material’s storage capacity by up to 56%.

A plug-and-play solar-powered battery back-up solution for the home

The OneBox, from Indian manufacturer Vision Mechatronics, consists of a lithium battery, hybrid inverter and solar charge controller to give a hassle-free solution for electricity back-up during power outages. Solar rooftop owners are offered a grid feed feature to maximize net metering income from any excess power generated.

Coupling pumped hydro with renewables and other storage technologies

The combination of pumped hydro with other storage technologies can increase renewables penetration, improve operational safety and reduce maintenance costs at large-scale hydropower plants, according to new research. The study also focuses on techniques to determine the optimal size of renewables-based pumped hydro storage systems. Costs for hybrid solar-pumped hydro projects currently range from $0.098/kWh to $1.36/kWh.

ADB extends $250 million loan to EESL for energy efficiency initiatives

The investment—part of a $592 million assistance package—will be used to promote adoption of smart meters, distributed solar photovoltaic systems and e-vehicles in India.
