Solar Panels Are Starting to Die, Leaving Behind Toxic Trash

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[…]

Transparent solar panels for windows hit record 8% efficiency

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.

Solar+battery in one device sets new efficiency standard

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[…]

Replacing lithium with sodium in batteries

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[…]

Boffins step into the Li-ion’s den with sodium-ion battery that’s potentially as good as a lithium cousin

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[…]

Study reveals single-step strategy for recycling used nuclear fuel

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[…]

Redox-Flow Cell Stores Renewable Energy as Hydrogen

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[…]

Electric Vehicle Battery Degradation Graph with 6 years data

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[…]
