Wello's Penguin WEC generates electricity at EMEC grid-connected wave test site
From Power-Technology: High-technology company Wellos Penguin wave energy converter (WEC) has successfully generated power into the national grid off the west coast of Orkney in Scotland, UK.
India Gets Record Low Bid to Build Solar Power, Minister Says
Anindya Upadhyay for Bloomberg: The price of solar power in India fell to a record low of 3.15 rupees (5 U.S. cents) a kilowatt-hour in a competitive tender where French firm Engie SAs local arm won rights to develop 250 megawatts.
Eon plots airborne wind route
Renews: Eon is collaborating with Dutch company Ampyx Power to develop the latters airborne wind energy system.
The agreement aims to further the development of the system towards commercial deployment.
This solar panel produces up to 5 liters of drinking water per day from the air
Derek Markham for TreeHugger: Zero Mass Water's Source device is a rooftop solar device that produces water instead of just electricity.
Tesla Just Unveiled Its Newest Solar Panels
Futurism: Tesla just updated their website to include images of their new low-profile solar panels. The panels integrate seamlessly with the Tesla Powerwall and can be ordered this month for production in the summer.
Wind turbine maker Vestas looks at expanding into energy storage
Reuters: Denmark's Vestas, the world's largest wind turbine maker, is keen to expand into areas such as energy storage to increase the global use of wind power and bring costs down.
Flower-shaped solar panel follows the sun
Megan Barber for Curbed: Based off the concept of how a sunflower follows the sun, the Smartflower is a portable, adjustable petal system that tracks the suns path throughout the day. When the sun rises in the morning, the Smartflower automatically unfolds and begins producing energy by setting its petals at a ninety-degree angle. The flower goes "back to sleep" into a folding position at night or whenever high winds make it unsafe to operate.
Low-cost 'solar absorber' promising for future power plants
Emil Venere for Phys.org: Researchers have shown how to modify commercially available silicon wafers into a structure that efficiently absorbs solar energy and withstands the high temperatures needed for "concentrated solar power" plants that might run up to 24 hours a day.
SAAB Gripen flies on 100 percent biofuel
The flights marked the first time a single-engined fighter flew with 100 percent biofuel. A twin seat Gripen D was used for the flights that took off from Saabs facilities in Linköping, Sweden.
Energy Harvesting Europe Article: A world without batteries
Energy Harvesting Europe Article: Governments, manufacturers and other interested parties agonise about what to do as multiple gigafactories spew out vast numbers of lithium-ion batteries that almost always die before the life of the equipment in which they are placed and they are linked to toxins, fires and other nasties. As the world moves to structural electronics instead of the nostalgic old components-in-a-box designs, the batteries are holding up the party because even solid state ones tend to swell and shrink with each cycle, bursting a smart structure apart.
The World's Biggest Solar Energy Storage Farm Is Set to Launch in Australia
David Nield for Science Alert: Construction will soon be underway on a gigantic solar farm in South Australia that's set to be the biggest of its kind in the world - thanks to 3.4 million solar panels and 1.1 million individual batteries.
The project is expected to be completed by the end of the year, at which point the huge plant should outdo all other solar farms in terms of overall battery capacity - although other solar facilities are larger in terms of land area.
NREL Publishes Landmark Residential Solar PV + Energy Storage Cost Breakdown
Joshua S Hill for CleanTechnica: The US National Renewable Energy Laboratory has published a landmark report extensively detailing component and system-level cost breakdowns for residential PV solar systems equipped with energy storage.
The decreasing cost of solar systems has been well documented over the last several years, with increased innovation and decreasing manufacturing costs combining to make solar PV a competitive and economic choice for residents and utilities across the United States, and in fact the world. As such, the costs attributed to the development of residential and utility-scale solar projects has been well defined for some time - even though that figure keeps decreasing.
Wind Energy Now Directly Competing With Coal On Cost
Gregory Brew for OilPrice.com: Last week, Xcel Energy announced a multi-state wind capacity project, anticipated to be the largest in the United States. Spanning seven states, the project covers eleven new wind farms and would generate 3280 MWs at a cost of $3.5-4.4 billion. In its announcement, Xcel emphasized the cost-savings attached to wind power, arguing that it would save Xcel customers in the Midwest $7.9 billion over thirty years. This, rather than the environmental benefits of renewable energy, drove the companys mission statement: wind was cheap, not just clean.
A Low-Tech Approach To Energy Storage: Molten Metals
Bruce Gellerman for WBUR: The ability to store energy promises to revolutionize the way we generate, transmit and use electricity - making renewable sources such as wind and solar cheaper and more dependable.
Massachusetts is one of just three states requiring electric utilities to build battery facilities in the future.
A company in Marlborough believes it literally has the next hot technology in energy storage: molten metals.
GTM: 10 US states have energy storage pipelines greater than 100MW
Danielle Ola for Energy Storage News: According to the latest GTM Research figures, energy storage is coming into its own and is no longer confined to a handful of US states. 21 states now have 20MW of storage projects proposed, in construction or deployed. Further, 10 states have pipelines of more than 100MW.
