Elon Musk says he can rebuild Puerto Rico's power grid with solar

BBC: Renewable energy entrepreneur Elon Musk says he could rebuild Puerto Rico's shattered electrical infrastructure with his solar energy technology.

Yet Another Energy Storage Breakthrough Coming, Thanks To "Weirdly Exciting" New Substance

Tina Casey for CleanTechnica: Bijel is short for "bicontinuous jammed emulsion gels." If that sounds somewhat mysterious, it's really not. You can almost DIY your own bijel right at the dinner table. Here's the explainer from Berkeley Lab:

Pumped hydro storage 'could make Australia run on renewable energy alone within 20 years'

Stephen Smiley and Caroline Winter for ABC AU: Australia has the capacity to store up to 1,000 times more renewable energy than it could ever conceivably need, according to an analysis by researchers at the Australian National University (ANU).

Solar Plus Storage Projects Will Increasingly Offer Resiliency

Peter Kelly-Detwiler for Forbes: The SRUSD will be able to cut energy costs (during some months, as much as 70-80% of the district's electricity needs will be met by the systems).

GE Working on Robot That It Says Can Save $200 Billion of Power

Anna Hirtenstein for Bloomberg: The technology would optimize how electricity flows in and out of storage devices such as batteries and points of consumption, in real time. This is expected to significantly increase the efficiency of the grid and save consumers money.

During Irma's Power Outages, Some Houses Kept The Lights On With Solar And Batteries

Adele Peters for Fast Company: The ability of some residences and businesses to stay functioning as the power went out around them shows the growing potential of local generation and microgrids. Now those batteries just have to get a lot cheaper.

MIT turns to millennia-old tech for renewable energy storage

Barbara Eldredge for Curbed: Indeed, MIT researchers have reinvented firebricks, a Bronze-Age technology created by the Hittites-who occupied what is today Turkey, in the 17th century BC. Firebricks were designed by the Hittites to retain heat for long periods of time, if properly insulated.

Solar with Energy Storage Success: Cuttyhunk Island, MA Celebrates Its First Summer Going Majority Solar-Powered

Solar Design Associates of Harvard, Massachusetts, designed and installed this 1,020-panel solar array and a 1 MW energy storage system that have delivered over 50% of the electricity this summer for Cuttyhunk Island, Massachusetts.

Nine-hour energy storage requirement makes one natural gas replacement project in California tricky

Andy Colthorpe for Energy-Storage News: The requirement of nine hours of energy storage duration at a project touted as a possible replacement for a new natural gas plant in California makes it tough for the newer technology to compete on cost, an analyst has said.

Boosting Tidal Power

NauticExpo: Developed by Netherlands-based Water2Energy, a vertical axis water turbine (VAWT) with an innovative pitch control system is proving from 30% to 50% more efficient than traditional systems.

Rail Energy Storage Harnesses the Power of Gravity All the Livelong Day

Glenn McDonald for Seeker: A California startup is repurposing trains and rail cars to help the storage capacity of renewable energy utilities compete with fossil fuels.

The Home Depot Converting 50 Rooftops to Solar Farms

The project will reduce electricity grid demand by an estimated 30 to 35 percent annually at each Home Depot store; the equivalent of powering 2,300 average U.S. homes for a year.

Solar eclipse 2017: how the solar power industry is prepping for a huge sunlight blip

Annette Choi for VOX: A model predicts the impact of the eclipse on the national solar energy supply will be greatest at 13:40 PM on August 21 while the eclipse is passing over Wyoming.

Mazda Combustion Technology News Sends Jolt Through Electric Car Industry

John Harrington for 247WallStreet: Mazda said in a press release that the engine technology will be up to 30% more efficient than the carmaker's conventional systems. It hopes to have the system ready for 2019 models.

Dynapower - MAXIMIZE PRODUCTION AND REVENUES WITH SOLAR PLUS STORAGE

The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach - coupling energy storage to PV arrays with a DC-to-DC converter - can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
