Nanotechnology is advancing so rapidly these days that it seems there is a new nanotech breakthrough being reported on a daily basis.  Top researchers from around the world are using nanotechnology to solve problems once considered impossible, and are even discovering new and interesting properties in our material reality along the way.

2011 alone has seen some major advances in nanotechnology applied to the energy sector, and the promise nanotech holds for renewable energy is exactly what the budding market needs to eventually overtake fossil fuels as the energy generation mode of choice. 

Super Efficient Solar Nantennas

University of Missouri researcher Patrick Pinhero and collaborators have developed microscopic antennas called, “nantennas,” that capture sunlight in both the visible and near-infrared spectrum as well as heat energy to create a thin-film solar sheet capable of 90 percent efficiency—far better than the 20 percent efficiency offered by current solar panels.

Energy Generation from Sound

Researchers at Sungkyunkwan University have created microscopic strings of zinc oxide that when exposed to sound vibrate between two electrodes, thus creating a charge. “Sound power can be used for various novel applications including cellular phones that can be charged during conversations and sound-insulating walls near highways that generate electricity from the sound of passing vehicles," says lead researcher Dr. Sang-Woo Kim.

Energy Transmission Via Nanotubes

A never-before witnessed energy effect has been observed by MIT scientists working with carbon “nanotubes.”  Apparently, heat waves travel through these microscopic tubes up to 10,000 times faster than normal while picking up ambient charged particles along the way, thus creating and electric charge.  This offers untold potential in energy transmission.

Focusing Energy with Nanocones 

Oak Ridge National Laboratory has created microscopic zinc oxide cones, dubbed “nanocones,” that exhibit the unique property of focusing and intensifying energy at the cones’ tips.  The nanocones have been applied to solar cells to boost efficiency.

Storing Energy with Nanosponges

University of Texas researchers have created carbon nano-supercapacitors called “nanosponges” which are capable of storing static-electric energy in their sponge-like pores.  Like traditional supercapacitors, nansponges can deliver energy faster and more efficiently than chemical-based batteries, but at a far higher capacity.  Currently, the nanosponges can store the energy equivalent of a lead-acid battery, but material improvements could put them on par with lithium-ion very soon.

Sungrow links Europe's largest energy storage plant to grid

Europe's largest energy storage project, the 100MWh Minety plant with Sungrow's 1500V energy storage system solutions, has connected to the UK grid

Europe's largest energy storage project, the 100MW/100MWh Minety plant featuring Sungrow's 1500V energy storage system solutions, has been successfully connected to the UK grid.

The UK experienced the most debilitating blackout in nearly a decade in August 2019. The incident exposed the serious lack of frequency regulation of the national grid and demonstrated that the construction of energy storage projects that can regulate the frequency of the grid in a timely fashion should be prioritised. The Minety project, which began at the end of 2019, considerably mitigates the problem and is designed for facilitating grid stability and maximising renewable energy utilisation.

Sungrow supplied both NCM and LFP battery energy storage system solutions featuring high integration, which minimise the footprint, slash the commissioning duration and significantly reduce the system cost by 5%. The solution well meets the latest UK frequency regulation requirement called dynamic containment - requesting the plant to respond to the power instruction of the grid within 1 second, making the project one of the rare 30% of the UK's storage plants equipped with this function.

"We are proud of being part of this landmark project, offering solutions with extreme efficiency and safety while in compliance with the stringent UK grid codes," said James Wu, Vice President of Sungrow, which shipped more than 800MWh of energy storage systems in 2020.

Battery storage capacity in the UK is likely to heavily increase as move towards operating a zero-carbon energy system. At the end of 2019 the GB battery storage capacity was 0.88GWh. National Grid forecasts it could be as high as 2.30GWh in 2025.

Global energy storage updates

TEVOCS has announced the launch of a powerful series of universal portable power stations that provide reliable power for off-grid situations, travel, home backup and more. With an impressive 2080WH capacity and 2000W output, the TEVOCS power station is billed as 'the ultimate power station for modern life' and is available here.

Enlight Renewable Energy has completed the acquisition of 90.1% of the holdings in Clēnera LLC, a leading and seasoned company in the field of initiation, development, construction and operation of solar energy and energy storage projects in the United States.

Last month Canadian Solar Inc. was awarded the first utility-scale battery storage project in Colombia of 45 MW/45 MWh. The project was awarded in the public tender launched by Colombia's Ministry of Energy and Mines, via its affiliate UPME, the Mining and Energy Planning Unit.
