IDTechEx will be hosting a free webinar on Thursday 14 June titled Redox Flow Batteries for Stationary Storage.

There is a global demand for more flexible wastewater treatment systems that are capable of operating independently of the electricity grid. As well as residential community treatment plants, there is also the need for mobile solutions that are able to serve the demands of military installations, mining sites, worker camps, disaster relief and refugee camps in a more energy efficient manner that reduces reliance on diesel generators.

At a meeting in Nigeria, nine African cities pledged to cut carbon emissions to zero within the next three decades.

By embracing renewable and hybrid solutions for off-grid tower locations, the mobile telecoms industry can increase network coverage whilst helping to stimulate the growth of the wider renewables industry.

Portugal produced more power from clean energy sources in March than it actually needed, marking the first time in the 21st century that renewables have topped 100% of its production.

Graphene-oxide membranes have attracted considerable attention as promising candidates for new filtration technologies. Now the much sought-after development of making membranes capable of sieving common salts has been achieved.

Electrochromic glass is the largest smart glass market today, and it is unlikely to be dethroned any time soon. For those unfamiliar with the technology, in its most common form it transitions from a clear or pale yellow to a vivid and dark blue (a result of the tungsten oxide electrochromic layer, as shown in diagram below), starting at the edges and moving inwards. It blocks light and heat to replace your blinds, and maybe your air conditioning too, but it is expensive.

Redox flow batteries are an energy storage technology initially developed by NASA in the 70's for space applications. After several years of intensive R&D, in 2006, several key patents on the technology expired, opening up the arena to companies all around the world.

The Samoan Government's goal of using 100% renewable energy for electricity generation by the year 2021 is on track.

Saildrone, Inc., a provider of high-resolution ocean data collected via a fleet of unmanned surface vehicles, announced that it has closed a $60 million round of Series B funding to scale up its global fleet of ocean drones to help monitor the state of the planet in real time.

The Australian Renewable Energy Agency will make up to $7 million of funding available for studying how how solar parks, wind farms or enabling technologies such as batteries can provide grid stability and security services.

In the first few months of 2018 Britain's wind farms produced record-breaking amounts of electricity, for the first time producing more than nuclear.

Highview Power announced that its Liquid Air Energy Storage system at the Pilsworth Landfill Facility outside of Manchester, UK is a finalist for the BusinessGreen Renewable Energy Project of the Year.

Successful entrepreneur Graham Hill has built an off-grid home in Hawaii.

A recent independent study by Imperial College London has evaluated the potential for new gravity-fed energy storage within the UK energy system. With tens of thousands of vertical mine shafts in the UK alone (UK Coal Authority), the potential initial market is sizeable.

Designed for embedding in space-constrained consumer designs like smart cards or hearing aids, the new chip builds on Powercast's existing Powerharvester receiver (PCC110), which has been deployed in industrial and commercial wireless power systems for seven years.

Hawaii legislature last week sent a bill to Governor David Ige's desk that directs the state's regulators to open a proceeding to create a microgrid services tariff to facilitate development and use of microgrids in Hawaii.

At ICREN Barcelona, April 2018, Dr Wilhelm Warta (Fraunhofer Institute for Solar Energy Systems ISE) noted that reducing the cost of electricity from PV calls for increasing the conversion efficiency of solar cells.

Solid state electrolytes have attracted tremendous attentions in recent years due largely to their commercial applications for highly safe energy storage and large energy storage devices.
