Off Grid

An increasing number of news articles about "Redox Flow Batteries" are present on the web. This technology, mostly adopted in on-grid and off-grid applications, has been studied for the last 50 years, and it is currently being commercialized (most of the time) in a containerized size, for medium- and large-scale applications.

The pandemic infection of COVID-19 has led to the lockdown of a considerable number of cities, leading to reduced pollution activity. With the large number of renewable energy sources employed in the last decades to decarbonise the energy sector, a growing number of energy storage devices have been coupled with renewable energy sources.

NextPower III, NextEnergy Capital's third institutional solar fund, is pleased to announce its first acquisition in Mexico.

For the first time, a soft and stretchable organic thermoelectric module has been created that can harvest energy from body heat. The breakthrough was enabled by a new composite material that may have widespread use in smart clothing, wearable electronics and electronic skin.

For the most part, solar cells have been limited to powering land- and space-based devices. While marine applications for solar cells do exist—for example, to power submerged autonomous vehicles and sensors—traditional photovoltaic materials like silicon cannot be used efficiently in deeper waters.

One of the last frontiers. Little used because the devices are not good enough. It lies between the much used microwave and infrared frequencies. Terahertz electromagnetic radiation has come centre stage recently with major breakthroughs claimed for THz emitters, trillionth-of-a-second switches, modulators and the sensors and there are conferences on the subject in several countries.

New solar powered smart bins have been installed in central Milton Keynes in a bid to keep the city centre clean, green and free of litter.

This article concerns production of electricity with zero emissions that is off-grid or capable of being off-grid when needed. That usually means a system that has energy storage and increasingly smart versions, those that manage supply and demand often for multiple loads and/or inputs. However, we also give some coverage to simple-single purpose versions such as a shipping container with a solar panel on it that creates fresh water by self-generated electricity powering desalination.
