Alternative Energy

Ships can become mobile wave energy converters, say Chinese researchers, using "heaving oscillators" that draw power from heaving, rolling and pitching movements as they move through the sea, while also acting as motion dampers to improve safety.

Google has announced that its innovative advanced geothermal plant in Nevada is now operational and connected to the grid, pioneering an approach that promises to unlock clean, always-on geothermal energy across a much larger range of locations.

Studying how bacteria interacts with the environment, a microbiology team discovered a powerhouse of an enzyme that consumes hydrogen and turns it into electricity. Researcher Rhys Grinter told New Atlas what the findings could mean for clean energy.

Russia is the only country that sells the HALEU fuel that some next-generation nuclear plants will rely on, and with sanctions now in place due to the war in Ukraine, TerraPower has now conceded its demo timeline will blow out by at least two years.

Japan's solar potential isn't great, but it does sit right next to one of the world's most powerful ocean currents – so the country is searching for novel ways to bulk up its green energy generation in the form of giant deep ocean turbines.

In a world first, a team at the University of New South Wales has demonstrated measurable power generation from "the inverse of a conventional solar cell." It could eventually produce around one tenth as much power as a solar panel – but at night.

Australian company Strategic Elements says it's made a step-change breakthrough in self-charging battery technology that harvests electrical energy from humidity in the air to directly power devices without ever needing to plug them in.

Scientists at Australia's Monash University claim to have made a critical breakthrough in green ammonia production that could displace the extremely dirty Haber-Bosch process, with the potential to eliminate nearly 2% of global greenhouse emissions.

Blue hydrogen isn't a step forward for the climate, says a new report out of Cornell and Stanford Universities. Indeed, it's worse than simply burning gas or coal in many applications – so it's not an acceptable transition phase in the race to zero.

A Scottish company called Gravitricity has now broken ground on a demonstrator facility for a creative new system that stores energy in the form of “gravity” by lifting and dropping huge weights.

When the US Air Force's X-37B autonomous spaceplane launched into orbit for the sixth time this week, it carried an experiment to explore the potential for beaming solar energy from space to Earth using microwaves.

Following a second grid-connected project at Jaffa Port in Israel, Eco Wave Power is looking to get more from its energy harvesters by adding solar.
