Store solar energy as liquid

A research group from Chalmers University of Technology, Sweden, has made great, rapid strides towards the development of a specially designed molecule which can store solar energy for later use. These advances have been presented in four scientific articles this year, with the most recent being pub Source: chalmers

A powerful new battery could give us electric planes that don’t pollute

MIT materials science professor Yet-Ming Chiang and his colleagues are developing a new battery specifically designed for an advanced hybrid plane. Brightly colored molecular models line two walls of Yet-Ming Chiang’s office at MIT. Chiang, a materials science professor and serial battery entrepreneur, has spent much of his career studying how slightly different arrangements of […]

Liquid-air energy storage: The latest new “battery” on the UK grid

A first-of-its-kind energy-storage system has been added to the grid in the UK. The 5MW/15MWh system stores energy in an unusual way: it uses excess electricity to cool ambient air down to -196°C (-320°F), where the gases in the air become liquid. That liquid is stored in an insulated, low-pressure container. When there’s a need […]

If Solar and Wind Are So Cheap, Why Are They Making Electricity So Expensive?

A question that gives pause: If Solar And Wind Are So Cheap, Why Are They Making Electricity So Expensive? Over the last year, the media have publishedstoryafterstoryafterstoryabout the declining price of solar panels and wind turbines. People who read these stories are understandably left with the impression that the more solar and wind energy we […]

Electric School Buses Can Be Backup Batteries For the US Power Grid

We often think of electricity as a one-way transaction. Need to toast a bagel, wash the sheets, or charge your phone? Your fuse box sends you the juice you need. Electric vehicles, though, have the capacity to send power back to the electrical grid using vehicle-to-grid (V2G) technology—and that’s good news for an aging grid […]

Researchers have developed a water-based battery to store solar and wind energy

The prototype manganese-hydrogen battery, reported April 30 in Nature Energy, stands just three inches tall and generates a mere 20 milliwatt hours of electricity, which is on par with the energy levels of LED flashlights that hang on a key ring. Despite the prototype’s diminutive output, the researchers are confident they can scale up this […]

Thin film converts heat from electronics into energy

Nearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 degrees Celsius and emanates from things like computers, cars or large industrial processes. Engineers at the University of California, Berkeley, have developed a thin-film system that can be applied to […]

Bring me a shrubbery: How tiny trees might fit in the biofuel future

Today, biofuels may conjure images of ears of corn or Priuses for US readers, but the domestic industry has been as much about politics lately as it has been about scientific innovation. While researchers and scientific organizations have looked into finding green energy sources in everything from human waste to humble algae,state and federal governments […]
