Is Hydrogen The Key To Clean Fuel?

Essentially what we do is take hydrogen-rich materials and combine them with a polymer to make a plastic-like material that we can extrude or press into pellets or rods.

Plug-and-play battery seeks to upstage Tesla

By Morgan Lee for the San Diego Union Tribune:  It looks like a simple floor lamp, or a sleek picture frame on the wall.  Inside lies a tantalizing future for household energy storage -- a 2 kilowatt-hour battery that plugs into a standard wall outlet and can keep an electrical circuit hot for several hours or more if a power outage strikes. The unproven concept for a plug-in-play battery was introduced Thursday by San Diego-based Orison during a forum at the University of California San Diego. Len Hering, executive director of the Center for Sustainable Energy, praised the 2-year-old startup's efforts in a news release. Orison CEO and co-founder Eric Clifton, drawing on seven years of experience in green technology startups, believes the battery tower and wall unit can play a prominent role in the emerging Internet of Things, providing the energy-storage equivalent of the Nest smart thermostat. "The way we look at it, we are the Nest of the energy industry," he said. Clifton believes that other early household battery entries -- most notably the Powerwall from electric car maker Tesla Motors -- miss the mark on bringing energy storage to the masses. Tesla's hefty home battery has to be professionally mounted and hardwired into household circuity, potentially involving inspections and permits. With Orison's batteries, you don't have to own a home, or even live in one, Clifton said. The batteries fit in with an apartment dweller in Manhattan.   Cont'd... ​

Super Battery Technology - High Capacity Cathode

Rather than relying upon conventional cathodes that use lithium-ion intercalation chemistry, an inherently slow process, we exploit the fast redox-reaction properties of our polymer to enable rapid charge and discharge.

Tesla already has reservations for $1bn worth of energy storage

Tesla has taken 100,000 reservations for its Powerpack and Powerwall battery products, worth approximately $1bn, according to founder Elon Musk. Speaking on the company’s quarterly earnings call, Musk said Tesla had taken reservations (non-binding agreements) which led him to believe the company would sell $50m of storage in the fourth quarter of 2015, and up to $500m in both 2016 and 2017. Musk said: "If you just take the reservations that have been made thus far, it's well over $1 billion worth of Powerpacks and Powerwalls. And that's with no marketing, no advertising, no sales force to speak of, really, we're not trying to sell it". Tesla chief technology officer Jeffrey Straubel, who was also on the call, said that around 70% of the reservations were for the larger 1MW Powerpack system, which is focused at commercial users and large-scale energy generators.   Cont'd...

Norway Could Provide 20,000MW of Energy Storage to Europe

Mike Stone  for GTM:  Norway has a lot of hydroelectric plants: a total of 937 of them, which provide a population of 5 million with around 98 percent of its electricity. In fact, the Scandinavian country is home to roughly half of all the hydroelectric water storage reservoirs in Europe. This vast system could also offer a Europe a substantial amount of energy storage -- up to 20 gigawatts of it -- if an ambitious scheme currently being proposed can overcome political and social hurdles and get the necessary funding. That’s according to Kaspar Vereide, an engineer at the Norwegian University of Science and Technology in Trondheim. And his models suggest it could all be achieved in seven years. Vereide is not alone in thinking Norway could become a vast green battery for Europe. The Centre for Environmental Design of Renewable Energy has concluded that there are four realistic scenarios for pumped hydro energy storage in the country, ranging from a Nordics-only scenario, where Norway only looks after its own needs, plus some of those of its Scandinavian neighbors; to a so-called ‘big storage’ scenario, which, it says, would see “Norwegian hydropower play an important role in integrating variable renewable sources into the European power system by providing large volumes of balancing over various time horizons to the North Sea countries through highly integrated grids and power markets.” It’s this "big storage" scenario -- with Norway becoming "the green battery of Europe" -- that Vereide has in mind.   Cont'd...

Battery Costs Set To Fall 60% By 2020 From Energy Storage 'Megashift'

By Sophie Vorrath for RenewEconomy:  The key role energy storage will play in the electricity grids of the future – and the vital importance of investing in and testing the various emerging battery storage technologies – has been highlighted in a major report published by the Australian Renewable Energy Agency on Monday, which predicts a 40-60 per cent price plunge for certain battery technologies by 2020. The 130-page report prepared by AECOM predicts a “mega-shift” to energy storage adoption, driven by demand – from both the supply side, as networks work to adapt to increasing distributed and renewable energy capacity, and from consumers wishing to store their solar energy – and by the rapidly changing economic proposition; a proposition, the report says, that will see the costs of lithium-ion batteries fall by 60 per cent in less than five years, and by 40 per cent for flow batteries.  Cont'd...

Renewable energy boom will mean vastly cheaper electricity

By Lucas Mearian, ComputerWorld:  Renewable energy, combined with prolific battery storage, will soon result in vastly cheaper electricity -- and solar power that's less expensive than what fossil fuel-based power plants can produce. Additionally, solar power with lithium-ion and flow-battery storage systems will make the combination of renewable energy so inexpensive that it will surpass nuclear power and obviate the need for futuristic power sources such as fusion. That was consensus view from a several keynote speeches delivered at the Intersolar Conference in San Francisco this week. Eicke Weber, director of the Fraunhofer Institute for Solar Energy Systems, said that in sun-rich countries, the cost of solar power is already below 5 cents per kilowatt and it will continue to plummet as battery storage systems become more prolific and less expensive.

Hydrogen Gas / Smoke Detector with Intrusion Alarm for Battery Room

From Eagle Eye Power Solutions: The Eagle Eye HGD-3000 Hydrogen Gas and Smoke Detector with (optional) Silent Intrusion Alarm is designed for unattended battery installations or remote shelters containing gassing lead acid batteries and charging systems... Lead-acid batteries on charge emit hydrogen gas after reaching the 80% recharge point. When mixed with enough air, hydrogen becomes a highly flammable gas that can ignite easily with just a spark, destroying equipment and harming personnel. The lower explosive level (LEL) for hydrogen is 4.1% by volume.  Hydrogen Gas Detection Attach the HGD-3000 to the wall, ceiling, or optional junction box using the mounting holes at the top and bottom of the detector box. The HGD-3000 will turn on an exhaust fan when hydrogen gas levels reach 1% and will alarm at 2%. This alarm consists of a local 80db horn, a flashing red LED, and a dry contact switch closure for remote alarming. Smoke Detection The photoelectric smoke sensor detects minute combustion products from smoldering wire insulation, battery cases, and other material. When smoke is detected, a distinctive alarm is emitted from the 80db horn and a separate dry contact switch is activated. At this time, the exhaust fan is inhibited in order to deny the fire increased oxygen from outside air. Temperature, Loss of Power, & Intrusion During normal operation and in the absence of an alarm condition, an internal thermostat will turn on the exhaust fan at a preset temperature to reduce heat buildup in the room. Loss of power to the unit will also generate a dry contact alarm. Additionally, an optional infrared intrusion alarm will trigger a silent dry contact switch. Product website

Is Home Energy Storage Coming to your House?

Home energy storage helps whichever energy source is the cheapest, and helps the grid stay stable and available to us all.

New benches that'll use solar power to charge your phone

This is the "Strawberry bench". The solar-powered smart bench (yes, really) collects energy via a solar panel on its roof, and uses it to power a range of functions: monitoring air quality, disseminating information about the local area, offering free power-ups for the phones of passers-by. This summer, four of these benches will be installed around Canary Wharf, the privately-owned office and retail estate at the heart of London's Docklands. The concept was the winner of the "Cognicity Challenge", a competition intended to find innovative proposals to use technology to create smarter urban environments (and, as a side effect, make everyone feel all warm and fuzzy towards the Canary Wharf Group). The name, incidentally, has nothing to do with actual Strawberries. The company behind them is Belgrade-based Strawberry Energy, whose previous products include the "Strawberry Tree", a vaguely familiar solar-powered mobile phone charge and wifi hub with a bench attached to it. Both products were the work of architect Milos Miliojevic.

New method can make cheaper solar energy storage

Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen, the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes water-splitting technologies too expensive to commercialize. EPFL scientists have now developed a simple, unconventional method to fabricate high-quality, efficient solar panels for direct solar hydrogen production with low cost. The work is published in Nature Communications. Many different materials have been considered for use in direct solar-to-hydrogen conversion technologies but "2-D materials" have recently been identified as promising candidates. In general these materials—which famously include graphene—have extraordinary electronic properties. However, harvesting usable amounts of solar energy requires large areas of solar panels, and it is notoriously difficult and expensive to fabricate thin films of 2-D materials at such a scale and maintain good performance. Kevin Sivula and colleagues at EPFL addressed this problem with an innovative and cheap method that uses the boundary between two non-mixing liquids. The researchers focused on one of the best 2-D materials for solar water splitting, called "tungsten diselenide". Past studies have shown that this material has a great efficiency for converting solar energy directly into hydrogen fuel while also being highly stable.   Cont'd...
