Researchers may have found a way to reduce the environmental impact of air travel in situations when electric aircraft and alternative fuels aren’t practical. Wired reports that Oxford University scientists have successfully turned CO2 into jet fuel, raising the possibility of conventionally-powered aircraft with net zero emissions. The technique effectively reverses the process of burning Read more about Scientists turn CO2 into jet fuel[…]
The Korea Superconducting Tokamak Advanced Research (KSTAR), a superconducting fusion device also known as the Korean artificial sun, set the new world record as it succeeded in maintaining the high temperature plasma for 20 seconds with an ion temperature over 100 million degrees (Celsius). On November 24 (Tuesday), the KSTAR Research Center at the Korea Read more about Korean artificial sun sets the new world record of 20-sec-long operation at 100 million degrees[…]
While setting fire to an iron ingot is probably more trouble than it’s worth, fine iron powder mixed with air is highly combustible. When you burn this mixture, you’re oxidizing the iron. Whereas a carbon fuel oxidizes into CO2, an iron fuel oxidizes into Fe2O3, which is just rust. The nice thing about rust is that Read more about Iron Powder Passes First Industrial Test as Renewable, Carbon Dioxide-Free Fuel[…]

By 2050, the International Renewable Energy Agency projects that up to 78 million metric tons of solar panels will have reached the end of their life, and that the world will be generating about 6 million metric tons of new solar e-waste annually. While the latter number is a small fraction of the total e-waste Read more about Solar Panels Are Starting to Die, Leaving Behind Toxic Trash[…]
In a step closer to skyscrapers that serve as power sources, a team led by University of Michigan researchers has set a new efficiency record for color-neutral, transparent solar cells. The team achieved 8.1% efficiency and 43.3% transparency with an organic, or carbon-based, design rather than conventional silicon. While the cells have a slight green Read more about Transparent solar panels for windows hit record 8% efficiency[…]
The drop in battery prices is enabling battery integration with renewable systems in two contexts. In one, the battery serves as a short-term power reservoir to smooth over short-term fluctuations in the output of renewable power. In the other, the battery holds the power for when renewable power production stops, as solar power does at Read more about Solar+battery in one device sets new efficiency standard[…]
An international team of scientists from NUST MISIS, Russian Academy of Science and the Helmholtz-Zentrum Dresden-Rossendorf has found that instead of lithium (Li), sodium (Na) “stacked” in a special way can be used for battery production. Sodium batteries would be significantly cheaper and equivalently or even more capacious than existing lithium batteries. The results of Read more about Replacing lithium with sodium in batteries[…]
scientists in America and China have created a sodium-ion-based battery that can potentially perform at close to the levels of Li-ion, paving the way for a cheaper, commercially viable alternative to lithium. The key challenge in creating this battery is that sodium-ion cells tend to break down faster than their lithium-ion cousins. Sodium crystals collect Read more about Boffins step into the Li-ion’s den with sodium-ion battery that’s potentially as good as a lithium cousin[…]
Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The platform developed by the Brown School of Engineering lab of Rice materials scientist Jun Lou integrates catalytic electrodes and perovskite solar cells that, when triggered by sunlight, produce electricity. The current flows to the catalysts that turn water Read more about ‘Artificial leaf’ concept inspires research into solar-powered fuel production[…]
A typical nuclear reactor uses only a small fraction of its fuel rod to produce power before the energy-generating reaction naturally terminates. What is left behind is an assortment of radioactive elements, including unused fuel, that are disposed of as nuclear waste in the United States. Although certain elements recycled from waste can be used Read more about Study reveals single-step strategy for recycling used nuclear fuel[…]
The solution, some propose, is to store energy chemically—in the form of hydrogen fuel—rather than electrically. This involves using devices called electrolyzers that make use of renewable energy to split water into hydrogen and oxygen gas. “Hydrogen is a very good carrier for this type of work,” says Wei Wang, who is the chief scientist Read more about Redox-Flow Cell Stores Renewable Energy as Hydrogen[…]
A rapid-charging and non-flammable battery developed in part by 2019 Nobel Prize winner John Goodenough has been licensed for development by the Canadian electric utility Hydro-Quebec.

These guys have 6 years of battery data on a range of electric cars. Each model is different in terms of degradation, but it seems that over six years time you lose around 12% of your battery capacity. This means that if your car was able to drive, say 523 km (Tesla Model X), after Read more about Electric Vehicle Battery Degradation Graph with 6 years data[…]

Growing demand for SUVs was the second largest contributor to the increase in global CO2 emissions from 2010 to 2018, an analysis has found. In that period, SUVs doubled their global market share from 17% to 39% and their annual emissions rose to more than 700 megatonnes of CO2, more than the yearly total emissions Read more about SUVs second biggest cause of emissions rise, figures reveal – turns out they are 11% more lethal to driver in an accident too, so maybe just a matter of time before that problem is fixed[…]
In 1999, at the peak of Hydrogen fuel cell company start ups in California he left BAe to start his own fuel cell company. “My old boss at Rolls Royce pointed out that the Hydrogen needed to come from somewhere.
