Tidal power: An inside look at how it works

From EnergyDigital:  Tidal power, a sister resource to wind, takes advantage of the predictability of the ocean tides to generate electricity, either via estuary barges or directly from the currents themselves via tidal streams. According to the Ocean Energy Council, the ideal area to net the most potential power is an area with a tidal range of at least seven meters. Energy can be generated via floating devices that drive hydraulic pumps, oscillating water columns within cylindrical shafts to create air movement, or hydropower turbines. The Pacific Northwest coast of the United States is an excellent location for tidal power, given its broad range of tide movement. According to Renewable Northwest, some areas of potential development include: • Makah Bay, Washington (by AquaEnergy Group) • Newport, Oregon (by Oregon State University / Oregon Department of Energy) • Tacoma Narrows (by Tacoma Power) • Puget Sound (by Snohomish County Public Utility District) The following sites are under development in Wales due to their wide tidal height variation and economically receptive marketplace: • Swansea Bay (by Tidal Lagoon Swansea Bay) • St. Asaph (by North Wales Tidal Energy & Costal Protection) As a whole, the UK has the potential for over 11,000 MW, a staggering amount given the relatively small landmass of the country. This makes it the single largest source of hydrokinetic power in Europe, enough theoretically support 10 percent of the world’s energy consumption.   Cont'd...

Small-scale solar power growing in the United States

By Daniel J. Graeber for UPI.com:  Small-scale solar installations in the United States account for about a third of the overall capacity on the grid, a report from the federal government said. The U.S. Energy Information Administration estimates total U.S. solar-power output in September, the last full month for which data are available, at 3.5 million megawatt hours. Of that, just more than 30 percent came from small-scale solar installations. "Generation from roof-top photovoltaic systems has become an increasingly important part of total solar generation in the United States," EIA AdministratorAdam Sieminski said in an emailed statement. A September report from the Solar Energy Industries Association, with support from green energy market adviser GTM Research, found second quarter residential solar capacity grew 70 percent year-on-year to 473 megawatts.   Cont'd...

German battery maker launches scheme to share solar power

Reporting by Vera Eckert for Reuters:  German battery maker Sonnenbatterie has launched a scheme to connect households with solar panels and other consumers, aiming to better distribute surpluses of the renewable energy and help members to become more independent of conventional suppliers. The start-up company hopes the scheme, called "sonnenCommunity", will boost demand for its batteries which store solar power, allowing owners to use the clean energy even when weather conditions are not favourable. SonnenCommunity takes the storage idea a step further, allowing solar power to be shared among its members. Sonnenbatterie said the scheme would initially target the 1.5 million solar power producers who, if they sign up to the community, will receive a battery storage system with a starting price of 3,599 euros ($3,812). But eventually, the offer will also be open to non-producers, it added. If the idea of battery-powered buildings takes off, it could pose a challenge to traditional utilities such as RWE and E.ON, which still derive the bulk of their power from big centralised power stations running on fossil fuels.   Full Article:

Mercedes Is Proposing A Novel Solution To Meet Energy Storage Demand

By Michael McDonald for OilPrice.com :  Ever since Tesla announced its PowerWall battery project earlier this year, interest in stationary storage and battery technology in general has been explosive. Now, Mercedes Benz has put together an interesting project built around recycled batteries that might help drive even more interest in grid scale utility storage and help to blend the consumer and commercial markets for batteries. Under Mercedes’ new project, a consortium of companies is going to create the world’s largest grid storage facility using used batteries in Lunen, Germany. The project will have the capacity to store 13 megawatts of power (enough to meet the demand of 130,000 homes) based on reusing automotive batteries. The basic premise is that when the battery from an electric vehicle or a plug-in hybrid vehicle is no longer reliable enough to start a car, it still has up to 80% of its original storage capacity remaining. As a result, a large series of these batteries can be connected to store energy from renewable sources like solar and wind power.   Cont'd...

Toronto Hydro to test world's first underwater energy storage system

Dario Balca , CTV Toronto:  Toronto Hydro has announced it will launch the world’s first-ever underwater energy storage system in Lake Ontario. The utility has partnered with Hydrostor Inc., a company that specializes in innovative energy storage systems, for a two-year-pilot project intended to create a backup for the city’s electricity grid big enough to power approximately 350 homes. "We're very excited to see this new technology in action,” said Toronto Hydro CEO Anthony Haines. “Toronto Hydro has been very busy exploring new ways to power our grid, and I think this is the most creative project we've been involved in so far. Supporting innovative solutions for Toronto's power needs will continue to be a focus for our organization." The system works by taking electrical energy and converting it into compressed air so that it can be stored under water in large, balloon-like structures. The storage facility will be located three kilometres off the southern tip of the Toronto Island and 55 metres under water. When the city’s electricity grid needs power, crews will open a valve that lets the pressurized air out. The air is then converted back into electricity and fed into the grid.   Cont'd...

Innovative energy storage project to be unveiled by Ryerson, eCamion

GREG KEENAN - The Globe and Mail:  Ryerson University in Toronto and a high-tech startup company called eCamion Inc. will unveil a pilot project Wednesday that allows energy to be stored in a unit that sits on hydro poles. An eCamion storage unit combined with a smart controller developed by Ryerson researchers and students will enable utilities such as Toronto Hydro to store power, integrate more renewable power and improve the reliability of the system, the company and Ryerson say. The unit uses lithium-ion batteries that charge during off-peak hours of hydro usage and discharge during peak hours. One of the benefits if the storage devices win widespread adoption is better availability of power for recharging electric vehicles, said Hari Subramanian, eCamion’s chief executive officer. “These are the enabling technologies you need for electric vehicles to really have an uptake,” Mr. Subramanian said. In many areas, the current hydro infrastructure could not handle the demand if several electric vehicles in a small section of a city were being recharged at the same time, he said. The storage device allows utilities to “flex their grid” to meet varying demands at various times, he said.   Cont'd...

Solar Power Thrives In Chile, No Subsidies Needed

William Pentland, Contributor for Forbes:  In Chile’s most recent power auction, the bids from solar project developers came in at between $65 and $68 per megawatt hour (MWh) were considerably more competitive than bids made by coal plants, which were priced at $85 per MWh. Solar power projects were awarded the lion’s share of the 1,200 gigawatt hours (GWh) of electricity contracts sold. Chile boasts one of the world’s biggest solar resources. High electricity prices and strong demand from Chile’s mining industry have driven demand growth for solar, especially large scale commercial or utility projects. The total installed solar capacity in Chile increased from less than 4 MW in 2013 to more than 220 MW last year. Nearly 1 GW of solar is projected to be installed in Chile in 2015. Meanwhile, a total of about 8 GW of solar power projects have been approved for development in Chile. First Solar and SunEdison are two of the biggest U.S. solar companies active in Chile.   Cont'd...

UK building the world's largest offshore wind farm

By Kelly Hodgkins for Digital Trends:  Danish state-owned company Dong Energy A/S plans to set a new world record for the world’s largest offshore wind farm, breaking the existing record currently held by the 630-megawatt London Array, another facility built by Dong. The new U.K. wind farm will be located in the Irish Sea, about 12 miles off the west coast of Great Britain.​ When commissioned, it will provide enough energy to power almost a half million homes. It’s no surprise that Dong is behind this effort, as it is Denmark’s largest energy company and the world’s largest developer of offshore wind power. The company has a longstanding relationship with the UK, constructing and, in some cases, operating multiple offshore wind facilities, including those in Barrow, Burbo Bank, and Walney Island. Between these projects and others in Germany, Dong now has a total of 5.1 gigawatts of offshore wind capacity. It aims to expand this capacity even further with a projected goal of 6.5 gigawatts of offshore wind energy production by 2020.   Cont'd...
