To power the energy transition, the world needs a reliable supply of critical minerals. Finding alternative materials can help secure the transition.
A single-walled carbon nanotube spring stores three times more mechanical energy than a lithium-ion battery, while offering wide temperature stability and posing no explosion risk.
Nissan says solid state batteries will double intensity of lithium batteries and cost less, and can also be used as energy storage.
Researchers have developed a high-performance energy management unit (EMU) that significantly boosts the efficiency of electrostatic generators for Internet of Things (IoT) applications. This breakthrough addresses the challenge of high impedance mismatch between electrostatic generators and electronic devices, unlocking new possibilities for ambient energy harvesting.
Electrostatic generators have emerged as a promising solution for powering low-power devices in Internet of Things (IoT) networks, utilizing energy from environmental sources such as wind and human motion. Despite their potential, the effectiveness of these generators has been hampered by an impedance mismatch when connected to electronic devices, leading to low energy utilization efficiency.
A study published in the journal Microsystems & Nanoengineering introduces an efficient energy management unit (EMU) designed to significantly boost the power efficiency of electrostatic generators for IoT devices. This innovation addresses the longstanding challenge of impedance mismatch and propels forward the potential for using environmental energy harvesting within the IoT domain.

Researchers in China have reportedly developed a new technology similar to hydropanels for harvesting water out of thin air that is powered by energy from the sun. The device could be especially useful in dry, arid areas where water — but not sunlight — is hard to come by.
Quaise Energy, a Massachusetts Institute of Technology spin-off, plans to vaporize rocks in the Earth’s core and tap into deep geothermal energy.
In a major clean energy benchmark, wind, solar, and hydro exceeded 100% of demand on California’s main grid for 30 of the past 38 days.
Stanford University professor of civil and environmental engineering Mark Z. Jacobson has been tracking California’s renewables performance, and he shares his findings on Twitter (X) when the state breaks records. Yesterday he posted:
Jacobson notes that supply exceeds demand for “0.25−6 h per day,” and that’s an important fact. The continuity lies not in renewables running the grid for the entire day but in the fact that it’s happening on a consistent daily basis, which has never been achieved before.

A small town in central Utah is set to be the home of a new underground “battery” that will store hydrogen as a clean energy source.
According to The New York Times, developers are creating two caverns as deep as the Empire State Building is tall from a geological salt formation near Delta, Utah. These caverns, which are expected to be complete next year, will be able to store hydrogen gas.
By analyzing the data from ESA’s Gaia satellite, Chinese astronomers have detected a new tidal stellar stream in the northern hemisphere, which has a low metallicity and a relatively high energy. The finding was reported in a research paper published April 1 in The Astrophysical Journal.
