The pursuit of fusion as a safe, carbon-free, always-on energy source has intensified in recent years, with a number of organizations pursuing aggressive timelines for technology demonstrations and power plant designs. New-generation superconducting magnets are a critical enabler for many of these programs, which creates growing need for sensors, controls, and other infrastructure that will allow the magnets to operate reliably in the harsh conditions of a commercial fusion power plant.
Denmark will build a wind-generating artificial Island. This green energy hub expected to supply 10GW.
The long-rumored island is expected to begin operations in 2033.
A 200-kilowatt demonstration version of Wave Swell Energy’s fascinating “blowhole” power generator has been deployed at Grassy Harbour on King Island, off the Australian island state of Tasmania and will be connected to the grid in the coming months.
Though the Earth’s deeper layers have been raging at thousands of degrees for billions of years, new research involving Florida Tech has shown that tapping into that heat to produce geothermal heating for urban regions on the surface has a far, far shorter lifespan.
The future for hydrogen fuel? 😃
Researchers have developed a magnesium-based POWERPASTE that stores hydrogen energy at 10 times the density of a lithium battery, ideal for small vehicles.
VANCOUVER, CANADA and WEST PERTH, AUSTRALIA – Ballard Power Systems (NASDAQ: BLDP; TSX: BLDP) today announced that it has signed a non-binding Memorandum of Understanding (MOU) with Global Energy Ventures (ASX: GEV; www.gev.com) – a provider of integrated compressed shipping solutions for the transportation of energy to regional markets, headquartered in Australia – for the development of a new fuel cell-powered ship, called C-H2 Ship, designed to transport compressed green hydrogen.
The power required for a small-scale demonstration of the C-H2 Ship is expected to be under 10 megawatts (MW). At full scale, the C-H2 Ship will have a propulsion power requirement of approximately 26MW, and a containment system for storage of 2000 tons of compressed green hydrogen.
Could there be a new kind of light in the universe? Since the late 19th century, scientists have understood that, when heated, all materials emit light in a predictable spectrum of wavelengths. Research published today in Nature Scientific Reports presents a material that emits light when heated that appears to exceed the limits set by that natural law.
In 1900, Max Planck first mathematically described a pattern of radiation and ushered in the quantum era with the assumption that energy can only exist in discrete values. Just as a fireplace poker glows red hot, increasing heat causes all materials to emit more intense radiation, with the peak of the emitted spectrum shifting to shorter wavelengths as heat rises. In keeping with Planck’s Law, nothing can emit more radiation than a hypothetical object that absorbs energy perfectly, a so-called “blackbody.”
The new material discovered by Shawn Yu Lin, lead author and a professor of physics at Rensselaer Polytechnic Institute, defies the limits of Planck’s law, emitting a coherent light similar to that produced by lasers or LEDs, but without the costly structure needed to produce the stimulated emission of those technologies. In addition to the spectroscopy study just published in Nature Scientific Reports, Lin previously published an imaging study in IEEE Photonics Journal. Both show a spike in radiation at about 1.7 microns, which is the near-infrared portion of the electromagnetic spectrum.
Use of waste heat contributes largely to sustainable energy supply. Scientists of Karlsruhe Institute of Technology (KIT) and Tōhoku University in Japan have now come much closer to their goal of converting waste heat into electrical power at small temperature differences. As reported in Joule, electrical power per footprint of thermomagnetic generators based on Heusler alloy films has been increased by a factor of 3.4.
