Method uses cheap carbon-based catalyst to deliver energy

Method uses cheap carbon-based catalyst to deliver energy
Groundbreaking research at Griffith University is leading the way in clean energy, with the use of carbon as a way to deliver energy using hydrogen. Professor Xiangdong Yao and his team from Griffith's Queensland Micro- and Nanotechnology Centre have successfully managed to use the element to produce hydrogen from water as a replacement for the much more costly platinum.

Primary balancing power stabilises grid frequency

Primary balancing power stabilises grid frequency
For more than 100 years, the Dörverden hydro power plant has been a reliable supplier of sustainable electricity. Now, the plant has been upgraded with a large Li-ion battery system from ads-tec. This highly dynamic system provides important network services for the local connection and, with a capacity of 3MW, regulates fluctuations in the grid's 50Hz rated frequency.

Desalination represents a 'hidden asset' for power

Desalination represents a 'hidden asset' for power
Renewable hydropower generated from desalination plants and other existing infrastructure would bring economic and environmental benefits to our biggest cities, according to new research from Griffith University. Based on studies focused on Warragamba Dam—the main water reservoir for Australia's biggest city, Sydney—scientists say their findings offer new options for government, industry and city planners on urban water and energy management.

Charging water by means of a mini water bridge

Charging water by means of a mini water bridge
Together with the Wetsus research centre in The Netherlands, researchers of TU Graz have managed to produce electrically charged water by means of a floating water bridge. Until its scientific rediscovery in 2007 at TU Graz, the "water bridge" phenomenon, discovered in the 19th century, had sank into oblivion. If extremely pure water, in other words water that has been distilled many times, is placed in two beakers and subject to a high voltage, the fluid moves up the side of each beaker and forms a floating water bridge between the two vessels.

Power cooling saves over a billion gallons of water

Power cooling saves over a billion gallons of water
The Liebert DSE pumped refrigerant economisation system from Emerson Network Power has been deployed in North American data centres and, in the last 36 months, has saved over 1.4 billion gallons of water. This process is an alternative to data centre chilled water cooling systems, and is expected to save an additional one billion gallons of water in 2016.

Big Data automates hydropower site selection process

Big Data automates hydropower site selection process
A technology under development has the potential to revolutionise the sourcing of renewable energy from rivers. A software app developed collaboratively by the University of Leicester and High Efficiency Heating UK automatically selects appropriate locations to site a large range of micro renewable hydro-power turbines in UK rivers, and determines the environmental sensitivity of each location.

Wave energy converters show increased power density

Wave energy converters show increased power density
Based in Stockholm and assisted by the KTH Royal Institute of Technology, CorPower Ocean has developed a compact, high-efficiency Wave Energy Converter, inspired by the pumping principles of the human heart. Using a new phase control method, the Wave Energy Converters always oscillate in resonance with the incoming waves, strongly amplifying their motion and power capture.

Portland's power's in the pipes

Portland's power's in the pipes
Portland, Oregon, has teamed up with start-up Lucid Energy to insert hydroelectric generators within the pipes carrying water beneath the city to produce power for Portland General Electric customers. With the unofficial slogan "Keep Portland Weird", it comes as no surprise that the northwestern city is the first to stick its head above the parapet and investigate the viability of this technology.

Barrier to tidal energy is not a mechanical one claims Altra

Barrier to tidal energy is not a mechanical one claims Altra
The cost of energy generated by tidal power generation is, at this stage of device development, still more expensive than that offered by offshore and onshore wind, and solar arrays in sunnier climes; however, fossil fuels will not last forever and investment is still going into accessing tidal power, one of the most reliable and predictable of renewable energy sources. Anthony George, from the Heavy Duty Clutch and Brake (HDCB) Division of Altra Industrial Motion has been involved in engineering a number of offshore energy projects and offers some analysis on the real-world viability of these schemes.

Crowbar resistors boast industry-high energy capability

Crowbar resistors boast industry-high energy capability
A new series of stainless steel braking/crowbar resistors have been announced by Vishay. Featuring industry-high pulse energy capability up to 3.46 MJ and pulse current capability up to 12 kA, the Vishay Draloric resistors can be optimized for frequency converters for three-phase generators in wind power plants and pumped-storage hydro power stations.
