A Simple, Cheap Material for Carbon Capture, Perhaps from Tailpipes

Carbon dioxide is the main greenhouse gas warming Earth and is emitted in large quantities in the flue gas from industrial and power plants. A new method for removing CO2 from these flue gases involves piping the emissions through a porous material based on the chemical melamine. DETA, a chemical bound inside the porous melamine, grabs CO2 and removes it from the gas, with nitrogen vented to the atmosphere.

Longer Lasting Sodium-Ion Batteries on the Horizon

Cheap and abundant, sodium is a prime promising candidate for new battery technology. But limited performance of sodium-ion batteries has hindered their large-scale applications. Now, a research team has developed a sodium-ion battery with greatly extended longevity in laboratory tests. An ingenious shift in the ingredients that make up the liquid core of the battery prevents the performance issues that have bedeviled sodium-based batteries.

Smashing Through the 30% Efficiency Barrier for Perovskite Solar Cells

For the first time, an efficiency of 30% for perovskite-on-silicon-tandem solar cells has been exceeded thanks to a joint effort led by scientists at EPFL's Photovoltaics and Thin Film Electronics Laboratory in partnership with the renowned innovation center, CSEM. Independently certified by the National Renewable Energy Laboratory in the United States, these results are a boost to high-efficiency photovoltaics and pave the way toward even more competitive solar electricity generation.

New Ultrathin Capacitor Could enable Energy Efficient Microchips

The silicon-based computer chips that power our modern devices require vast amounts of energy to operate. Despite ever-improving computing efficiency, information technology is projected to consume around 25% of all primary energy produced by 2030. Researchers in the microelectronics and materials sciences communities are seeking ways to sustainably manage the global need for computing power.

30-Year Perovskite Solar Cells, New Approach to Testing

Researchers have developed the first perovskite solar cell with a commercially viable lifetime, marking a major milestone for an emerging class of renewable energy technology. The team projects their device can perform above industry standards for around 30 years, far more than the 20 years used as a threshold for viability for solar cells.

Cybersecurity Tools to Protect Solar, Wind Power on the Grid

Solar panels and wind turbines, now projected to produce 44% of America's electricity by 2050, present cybersecurity challenges. They have sensors, controllers, actuators or inverters that are directly or indirectly connected to the internet. They're distributed far and wide across the country and the countryside. Many have insecure connectivity to legacy electric grid systems. They have complex physics. They're subject to advanced persistent threats. And there will be more and more of them going online.

Developing a Toolchain to Assess Performance of Wind Energy Systems

The goal of the project is to achieve a better understanding of the unsteady inflow conditions at altitudes above the first layer of air above the ground (the surface layer). The aim is to develop a toolchain to efficiently and effectively assess the performance and reliability of airborne wind energy devices and conventional wind turbines. This is important to site evaluation but also for increasing the wind plant efficiency and making the operation of airborne wind energy systems safer.
