Discovery of one-dimensional topological insulator

Posted by in categories: quantum physics, solar power, sustainability

A joint research team has unveiled a new topological insulator (TI), a unique state of matter that differs from conventional metals, insulators, and semiconductors. Unlike most known TIs, which are either three-or two-dimensional, this TI is one-dimensional. The breakthrough will lead to further developments of qubits and highly efficient solar cells.

Details of the research were published in the journal Nature (“Observation of edge states derived from topological helix chains”).

TIs boast an interior that behaves as an electrical insulator, meaning electrons cannot easily move; Whereas its surface acts as an electrical conductor, with the electrons able to move along the surface.

Enel Green Power lands finance for first solar and battery hybrid project

Posted by in categories: finance, solar power, sustainability

Enel Green Power Australia has announced that it has secured project financing for a $190 million solar and battery hybrid project it plans to build in western NSW.

The Quorn Park hybrid project will combine a 98 MW (dc) solar farm with a 20 MW, 40 MWh battery that will be built around 10kms north west of Parkes. Construction will commence within the next few months and it will be operational in 2026.

The new hybrid is one of the first to be announced since new rules were introduced that allow wind or solar farms to be truly “paired” with a battery storage facility, rather than operating and dispatching as separate units. This may impose some restrictions on operations, but can save on connection and other costs.

Stanford Unveils Game-Changing Liquid Fuel Technology for Grid Energy Storage

Posted by in categories: solar power, sustainability

Stanford scientists are enhancing liquid fuel storage methods by developing new catalytic systems for isopropanol production to optimize energy retention and release.

As California transitions rapidly to renewable fuels, it needs new technologies that can store power for the electric grid. Solar power drops at night and declines in winter. Wind power ebbs and flows. As a result, the state depends heavily on natural gas to smooth out the highs and lows of renewable power.

“The electric grid uses energy at the same rate that you generate it, and if you’re not using it at that time, and you can’t store it, you must throw it away,” said Robert Waymouth, the Robert Eckles Swain Professor in Chemistry in the School of Humanities and Sciences.

Solar-powered skin for prosthetic limbs

Posted by in categories: biotech/medical, cyborgs, solar power

A synthetic skin for prosthetics limbs that can generate its own energy from solar power has been developed by engineers from Glasgow University.

Researchers had already created an ‘electronic skin’ for prosthetic hands made with new super-material graphene.

The new skin was much more sensitive to touch but needed a power source to operate its sensors.

US hits 180 GW of solar power. Here’s how we get to 1,000 by 2035

Posted by in categories: solar power, sustainability

Collectively, the US’s 5 million solar installations can generate more than 179 gigawatts (GW) of electricity. Based on current trends, the SEIA claims that the US’s total solar capacity will soar to 673 GW by 2034, providing enough electricity to power 100 million homes.

The US will likely need to do better than that to meet the Biden Administration’s goal of 100% clean electricity by 2035, though. To decarbonize the grid by then, the Department of Energy (DoE) expects we’ll need as much as 1 terawatt (1,000 GWs) of solar capacity, enough for solar to meet 30–50% of the US’s electricity demand by itself.

Artificial photosynthesis to produce hydrogen peroxide

Posted by in categories: chemistry, solar power, sustainability

National University of Singapore (NUS) chemists have developed hexavalent photocatalytic covalent organic frameworks (COFs) which mimic natural photosynthesis for the production of hydrogen peroxide (H 2 O2), an important industrial chemical.

The conventional method of H 2 O2 production involves using anthraquinone as a catalyst to convert air and hydrogen into H 2 O2. However, this process requires substantial energy, costly noble metal catalysts, high-pressure hydrogen gas and hazardous solvents. Artificial photosynthesis of H 2 O2, resembling the natural photosynthesis process with the use of sunlight as an energy source and abundant water and air as feedstocks, presents a sustainable and promising alternative to the conventional anthraquinone process.

However, such an artificial system faces three key challenges: insufficient charge carrier generation and fast charge recombination, which lowers the efficiency; limited number of available catalytic sites, which results in low productivity; and lack of efficient delivery of charges and reactants to the catalytic sites, which causes sluggish reaction kinetics.

‘Dyson spheres’ were theorized as a way to detect alien life. Scientists say they’ve found potential evidence

Posted by in categories: alien life, solar power, sustainability

O.o!!!! Woah even the news is talking about Dyson spheres now o.o

By Jacopo Prisco, CNN

(CNN) — What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces.

China opens world’s biggest solar farm that spreads over 200,000 acres

Posted by in categories: solar power, sustainability

China has just connected what it believes to be the world’s biggest solar power plant to the grid in northwestern Xinjiang. The plant covers an area of 200,000 acres and is reported to have an output of 6.09 billion kWh annually.

The new plant is in the deserts near the region’s capital Ürümqi. The site came online this Monday (June 3) and is being run by the Chinese state-owned Power Construction Corporation, according to Reuters.

Smelting Steel Without Fossil Fuels: Solar Power Shatters the 1,000°C Barrier for Industrial Heating

Posted by in categories: solar power, sustainability

Swiss researchers have developed a solar energy method using synthetic quartz to achieve temperatures above 1,000°C for industrial processes, potentially replacing fossil fuels in the production of materials like steel and cement.

Instead of burning fossil fuels to reach the temperatures needed to smelt steel and cook cement, scientists in Switzerland want to use heat from the sun. The proof-of-concept study uses synthetic quartz to trap solar energy at temperatures over 1,000°C (1,832°F), demonstrating the method’s potential role in providing clean energy for carbon-intensive industries. A paper on the research was published on May 15 in the journal Device.

The Need for Decarbonization.
