Clayton Power made it possible for Per Aarsleff to both go green and reduce costs by clever implementation of mobile hybrid power systems based on lithium technology.
Because the materials involved are inexpensive and the fabrication is simple, this approach has the potential to be scaled up for production at commercial levels.
ydney-based energy investment group Tag Pacific has today announced it has won a landmark deal to deliver Australia’s largest energy storage system to be operated alongside the University of Queensland-owned Gatton solar power plant in south-east Queensland. The battery storage project, valued at around $2 million, was won by Tag’s wholly owned power business MPower, which is also working with Rio Tinto and First Solar in the remote town of Weipa, Queensland, to build an ARENA-supported 1.7MW solar PV project, which will serve a remote bauxite mining operation and could be expanded to 6.7MW The newly announced energy storage project, will be grid connected; a slightly different tack for MPower, which has tended to specialise in remote, and off-grid solar plus storage hybrid systems.
When hydrogen is compressed, it is much more energy-dense than even the most advanced batteries.
In the Lloydminster area, a Calgary company is ready to carve out large underground salt caverns to store excess wind energy — the first use of the technology in Canada. Rocky Mountain Power president Jan van Egteren says the storage sites could be ready in five years. Salt caverns have been used to store natural gas for years, but only two other projects in North America are using them for compressed air that is turned into electricity. The caverns are carved out by pumping water deep down to dissolve the underground salt layer peculiar to the Lloydminster area. Excess wind electricity would be used to pump compressed air into caverns about the size of a 60-storey building. The salt walls allow very little to escape. Then, when the wind dies, the compressed air is released and used to turn a generator to make electricity. The cavern could store enough compressed air to provide electricity for five days to a city the size of Red Deer, says van Egteren. “It could really help stabilize the grid by taking off power when the wind is really blowing.”
The Fuel Cell Industry Review 2014 offers data and analysis by region, application, and fuel cell type, and includes objective commentary on key events in the industry over the past year.
ITM Power, the energy storage and clean fuel company, is pleased to note that the world's largest carmaker, Toyota, announced that it will begin selling fuel-cell electric cars in Japan on 15 December, 2014, and in the US and Europe in mid-2015.
From high efficiency to scalability, fuel cells provide a distinct advantage over incumbent energy generation technologies, which is why top companies, governments, and the military are adopting fuel cells for everyday use.
Siemens is developing a system of storing thermal energy in rocks with the aim of using it to harness excess power from wind turbines. A spokesperson told Windpower Monthly that the project is in the early stages of development and there is no specific timescale for the construction of a prototype of the system. He said the system would be scaleable for use on site at different projects. The company was unwilling to reveal specific technical details about the process, but said it relied on established technology. The storage of heat in rocks has been used as a method of energy retention for some time. But Siemens' system will transform the stored thermal energy back into electricity rather than use it for heating. This would be done in a "conventional manner" the spokesperson said. The captured heat would be used to create steam to generate electricity through steam turbines.
The Enphase system intelligently integrates the critical technologies needed to solve solar energy challenges at scale: smart grid intelligence, communications, big data analytics and storage.
California could be at the forefront of these car insurance savings because it is one of the earliest adopters of clean cars (including Hybrids, Plug Ins & electric cars) in the nation.
Sunrun, the largest dedicated residential solar company in the United States, today announced a partnership with OutBack Power Technologies, Inc. to pilot renewable energy storage-based systems for a select group of Sunrun solar customers. OutBack Power is a designer and manufacturer of power conversion systems incorporating energy storage for off-grid and grid-connected renewable energy applications. As part of the pilot, Sunrun will combine and test OutBack Power's technology consisting of weather-resistant batteries and inverters with home solar systems in both indoor and outdoor environments. "It is now more affordable than ever for consumers to run their homes with clean power, and we strongly believe that the next evolution of solar as a service for our customers is home solar paired with energy storage," said Sunrun's chief operating officer, Paul Winnowski. "With OutBack Power, we will further our commitment to providing customized and affordable home solar that allows customers to be a part of the solution for building a clean, modern grid that provides power when it is needed the most."
Using batteries to retain energy from rooftop solar systems will be too expensive for at least two years, according to industry executives. That means homeowners who add solar panels to save money on utility bills will continue to lose electricity during blackouts, even after an 80 percent decline in battery costs over the past decade. Residential solar systems typically send power to the grid, not directly to the house, and don’t run the home during a blackout. For batteries to save consumers money, stored energy must be drained daily, said Jamie Evans, who runs the U.S. Eco Solutions unit for Panasonic Corp., which supplies lithium-ion cells for Tesla Motors Inc. “Solar will need storage for grid stability,” Evans said yesterday in an interview at the Solar Power International convention in Las Vegas. “Battery costs need to come down and regulatory structures have to change to really scale up.” As residential solar become more common from California to New York, utility grids will increasingly become stressed without storage to ease supply and demand imbalances, he said. For now, that means battery storage only makes economic sense for large businesses that get hit with extra fees when their power usage exceeds utility expectations.
Looking to 10 years from now, if energy storage achieves its full potential then the whole landscape for power generation and distribution could change drastically.
While an electric vehicle may go 200 or 250 miles without a charge a combination of fuel cell and fuel together with a balance of system could travel 500 or even 800 miles depending upon the specific requirements and design.

Our batteries have Xtreme thick plates with (XC Diamond Plate Technology) added to them. They have been designed for hours of heavy discharge each day, followed by a fast recharge during the daylight hours. Very few batteries can take the grueling deep discharge-recharge cycle every day for long periods of time. U.S. Battery has proven time and time again that our solar battery line can stand up to this type of battery torture day in and day out for years to come. When you demand reliable energy storage count on U.S. Battery every time!
