Does Switzerland need more dams and reservoirs?

Does Switzerland need more dams and reservoirs?
The tense economic situation and the high supply of subsidised energy from solar, wind, and coal in Europe has made it difficult for Swiss hydropower to remain economically competitive. The facilities and production of future hydropower projects must be more flexible in order to successfully face an uncertain market and to increase the security of supply in Switzerland.

System generates electricity from osmosis

System generates electricity from osmosis
Proponents of clean energy will soon have a new source to add to their existing array of solar, wind, and hydropower: osmotic power. Or more specifically, energy generated by a natural phenomenon occurring when fresh water comes into contact with seawater through a membrane. Researchers at EPFL's Laboratory of Nanoscale Biology have developed an osmotic power generation system that delivers never-before-seen yields.

Small-scale hydropower to be applied in developing nations

Small-scale hydropower to be applied in developing nations
Engineers at Oregon State University have created a computer modelling package that people anywhere in the world could use to assess the potential of a stream for small-scale, "run of river" hydropower, an option to produce electricity that's of special importance in the developing world. The system is easy to use; does not require data that is often unavailable in foreign countries or remote locations; and can consider hydropower potential not only now, but in the future as projected changes in climate and stream runoff occur.

Hybrid nanogenerator harvests ocean waves

Hybrid nanogenerator harvests ocean waves
In a study published in ACS Nano, a team of researchers led by Zhong Lin Wang at the Georgia Institute of Technology has developed a device that can harvest ocean waves in a very broad frequency range that encompasses almost all of the ocean wave energy spectrum, including the hard-to-reach low frequencies that are inaccessible to most harvesters. The device is a hybrid system that consists of two generators.

Method efficiently produces hydrogen peroxide from seawater

Method efficiently produces hydrogen peroxide from seawater
Scientists have used sunlight to turn seawater (H2O) into hydrogen peroxide (H2O2), which can then be used in fuel cells to generate electricity. It is the first photocatalytic method of H2O2 production that achieves a high enough efficiency so that the H2O2 can be used in a fuel cell. The researchers, led by Shunichi Fukuzumi at Osaka University, have published a paper on the method of the photocatalytic production of hydrogen peroxide in a recent issue of Nature Communications.

Power station output increases by 15% following upgrade

Power station output increases by 15% following upgrade
The Lochay Power Station in Killin, Scotland, has had its hydro generator refurbished by Sulzer, which combined the skills of the local service centre in Falkirk and the coil shop in Birmingham to improve the design and construction of the generator to increase output and efficiency.

The latest mechanism for catalysing the splitting of water

The latest mechanism for catalysing the splitting of water
Mobilising oxygen atoms from the crystal surface of perovskite-oxide electrodes to participate in the formation of oxygen gas is key to speeding up water-splitting reactions, researchers at MIT, the Skoltech Institute of Technology, and the University of Texas at Austin show in a new paper published online in Nature Communications. This work is crucial for the widespread adoption of water splitting to produce hydrogen fuel, an attractive way to depart from traditional energy sources such as fossil fuels towards clean, renewable energy sources.

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.
