Comments Off on This carbon nanotube yarn generates power when pulled

Power-producing materials are the stuff of wearable inventors’ dreams. And scientists just created a yarn that generates electricity with a simple tug. The yarn, comprised of carbon nanotubes and submerged in an electrolyte gel, isn’t ideal for sweaters – but can harvest power from a wearer’s breathing. And there’s another surprising application: it could collect energy from ocean waves . An international team of 29 researchers devised the the yarn material, known as twistron harvesters, “by tying a carbon nanotube string into a tangled weave of carbon and submerging it into an electrolyte gel,” according to Science Magazine. When covered in gel and tugged, the yarn can illuminate a light-emitting diode with a small current. The yarn’s peak power generation – when strands are hooked together – is 250 watts per kilogram, and Ars Technica pointed out a professional cyclist’s peak exertions are only around 10 percent of that figure.

The researchers also connected the yarn to an artificial muscle – a polymer that contracts when warmed, according to Ars Technica – and were able to convert fluctuations in temperature into energy . A still more unexpected way the yarn could be used is in wave power . The material operates when it’s placed in saltwater similar to the ocean, and the motion of the waves moves the yarn, allowing it to generate power. Ars Technica notes the device does need a platinum electrode as seawater can be corrosive. The proof of concept yarn strands aren’t yet powerful enough to brighten a home, but the scientists say their technology is scalable. The journal Science published the research in late August. Scientists from institutions in South Korea, the United States, and China contributed to the study. Via Science Magazine and Ars Technica Images via The University of Texas at Dallas and screenshot

World’s first wave energy microgrid project due off Western Australia coast

Comments Off on World’s first wave energy microgrid project due off Western Australia coast

Wave power offers huge promise as a source of clean energy, and now Australia’s Carnegie Wave Energy is taking the technology to bold new places with the world’s first wave-integrated renewable energy microgrid project to be connected to an electricity network. Cleantechnica reports that Carnegie’s Garden Island Microgrid Project will include the company’s CETO 6 array, which is currently in progress – along with an existing reverse osmosis desalination plant that was fired up last week. The project will also boast two megawatts peak solar PV power, along with enough storage for safe, stable and reliable connections to the larger power grid. Click here to view the embedded video. Carnegie is already shipping power from offshore to the mainland of Australia via its CETO 5 array, which went online off the coast of Perth just seven months ago. CETO 6 just left the conceptual phase two weeks ago, but it’s expected to produce about four times more power than its predecessor – maxing out at 1 megawatt of generation. Related: United States investing $10 million in wave power projects Carnegie CEO Michael Ottavaiano said Western Australia is a great place to build a project like this because there’s no need to build and maintain long transmission lines to coastal communities. He added that the Garden Island project, as it’s known, will also help demonstrate the potential the company sees to integrate its wave energy technology into islands and fringe grid applications, or basically wherever strong waves are to be found. “Carnegie’s island power projects will invariably involve integrating CETO with other renewable energy power sources, desalination plants, diesel generation and increasingly energy storage,” he said in a statement on Thursday,” Ottaviano told Cleantechnica . “This project will also be a great opportunity to demonstrate a real world, wave integrated microgrid system to our island customers.” Via Cleantechnica Images and video via Carnegie Wave Energy

Comments Off on Perth’s Carnegie Wave Energy project produces power AND fresh water from the motion of the ocean

Click here to view the embedded video. The Carnegie Perth Wave Energy Project is rolling out its multimillion-dollar plans to prove that waves can generate real power for the electric grid on land. Submerged in the roiling seas off the coast of Perth in Western Australia, buoy-like CETO technologies will harness energy from incoming swells and convert it into electricity and desalinated water—no greenhouse gas emissions required.

New report shows that Scotland could be fossil fuel-free by 2030

Comments Off on New report shows that Scotland could be fossil fuel-free by 2030

A new WWF-backed study by consultancy giant DNV-G L shows that Scotland can go 100% fossil fuel-free by the year 2030, and that it could reduce carbon intensity from 271 grams of CO2 per kilowatt hour to 50g CO2/kwh. The plan outlined in the report is separate from the government’s goal of providing 100% of electricity demand from renewables by 2020, which currently would still allow for the use of coal and gas in energy generation.
