From the Ashes: Coal Ash May Offer Rich Source of Rare Earth Elements
For most of history, the world got along fine without the rare earth elements. We knew they existed, we knew they weren’t really all that rare, and we really didn’t …read more Continue reading From the Ashes: Coal Ash May Offer Rich Source of Rare Earth Elements
Long-life low-carbon concrete switches 80% of its cement for coal ash
Coal ash is abundant around coal-fired power stations. In fact, that might be considerably understating things – globally, power stations produce around 1.2 billion tonnes annually, and in Australia coal ash accounts for nearly 20% of all waste. It’s a… Continue reading Long-life low-carbon concrete switches 80% of its cement for coal ash
You Got Fusion in My Coal Plant!
While coal was predominant in the past for energy generation, plants are shutting down worldwide to improve air quality and because they aren’t cost-competitive. It’s possible that idle infrastructure could …read more Continue reading You Got Fusion in My Coal Plant!
Coal-to-protein livestock feed uses 1/1000th as much land as farming
Chinese scientists have developed a cost-effective method of converting coal into protein, which they say could feed livestock much more efficiently than natural plants, while using a tiny fraction of the land.Continue ReadingCategory: ScienceTags: Agr… Continue reading Coal-to-protein livestock feed uses 1/1000th as much land as farming
Coal’s green potential: storing energy instead of being burned for it
Coal is not generally thought of as a clean fuel source, but it might yet have a role to play in the push for greener energy. Researchers say that it could be a great material in which to store hydrogen gas, which is one of the most promising clean fue… Continue reading Coal’s green potential: storing energy instead of being burned for it
Coal to Nuclear Transition to Decarbonize the Grid
We love big projects here at Hackaday, and one of the biggest underway is the decarbonization of the electric grid. The US Department of Energy (DOE) recently published a report …read more Continue reading Coal to Nuclear Transition to Decarbonize the Grid
Energy-related CO2 emissions hit record high as the world counts on coal
Though the lockdowns brought on by the coronavirus pandemic led to some extreme dips in global carbon emissions, new analysis from the International Energy Agency (IEA) has shown how insignificant they may be in the grand scheme of things. Global emiss… Continue reading Energy-related CO2 emissions hit record high as the world counts on coal
Coal could find new use in eco-friendly desalination tech
The burning of coal may be falling out of favor as a means of generating heat and electricity, but that doesn’t mean the material no longer has any valuable uses. According to a new study, it could be utilized in the desalination of seawater.Continue R… Continue reading Coal could find new use in eco-friendly desalination tech
“Melting choc chip” blocks could stack up as grid-scale energy storage
Engineers from the University of Newcastle have come up with a surprisingly simple new energy storage system, built around blocks that store thermal energy like melted chocolate chips in a muffin. The team says they’re efficient, scalable, safe, inexpe… Continue reading “Melting choc chip” blocks could stack up as grid-scale energy storage
