A nuclear fusion reaction has lasted for 30 seconds at temperatures in excess of 100 million°C. While the duration and temperature alone aren’t records, the simultaneous achievement of heat and stability brings us a step closer to a viable fusion reactor – as long as the technique used can be scaled up. Most scientists agree Read more about Korean nuclear fusion tokamak reactor achieves 100 million°C for 30 seconds[…]
With Russia closing the gas pipelines to Europe as a catalyst and using the people of Finland as blackmail material the Finnish government is taking control of company payment structures and grabs 1% of any company that signs up to the possibility of taking a loan from the government at extortionate interest rates. It’s pretty Read more about War profiteering Finland govt nationalises 1% of energy companies[…]
Hydrogen fuel promises to be a clean and abundant source of energy in the future – as long as scientists can figure out ways to produce it practically and cheaply, and without fossil fuels. A new study provides us with another promising step in that direction, provided you can make use of existing supplies of Read more about Scientists Find a Simple Way to Produce Hydrogen From Water at Room Temperature[…]
A major breakthrough in nuclear fusion has been confirmed a year after it was achieved at a laboratory in California. Researchers at Lawrence Livermore National Laboratory’s (LLNL’s) National Ignition Facility (NIF) recorded the first case of ignition on August 8, 2021, the results of which have now been published in three peer-reviewed papers. Nuclear fusion Read more about Nuclear Fusion Breakthrough Confirmed: California Team Achieved Ignition[…]
Virtually all wind turbines, which produce more than 5 percent of the world’s electricity, are controlled as if they were individual, free-standing units. In fact, the vast majority are part of larger wind farm installations involving dozens or even hundreds of turbines, whose wakes can affect each other. Now, engineers at MIT and elsewhere have Read more about A new method boosts wind farms’ energy output, without new equipment[…]
“Switch to solar panels to help save the planet,” they say. And they’re (mostly) right. Solar panels are a great source of clean energy because, unlike fossil fuels, solar energy doesn’t produce harmful carbon emissions while creating electricity. But how “clean” is the process of creating solar panels? Ironically enough, solar panel production is reliant Read more about The Environmental Impact of Solar Panels[…]
The aviation industry’s attempts to go green are getting a boost from an unlikely place: carbon-neutral jet fuel pulled from thin air. That may seem far-fetched, but it’s a concept that engineers at the Swiss Federal Institute of Technology (ETH) have not only proved experimentally, but apparently proven again at scale. Even better, the fuel Read more about Pull jet fuel from thin air? We can do that, say scientists[…]

Turkey announced last week it discovered a massive rare earth reserve almost as big as the world’s largest in China. The find is reportedly so large that it could on its own satisfy global demand for decades. According to the Turkish Ministry of Energy and Natural Resources, the country found a supply of 694 million Read more about Turkey’s Newfound Cache of Rare Earths Could Supply the World’s EVs and More[…]
Finnish researchers have installed the world’s first fully working “sand battery” which can store green power for months at a time. Using low-grade sand, the device is charged up with heat made from cheap electricity from solar or wind. The sand stores the heat at around 500C, which can then warm homes in winter when Read more about Finnish ‘Sand battery’ built in Tampere[…]
Researchers from the University of Cambridge have managed to run a computer for six months, using blue-green algae as a power source. A type of cyanobacteria called Synechocystis sp. PCC 6803 – commonly known as “blue-green algae,” which produces oxygen through photosynthesis when exposed to sunlight, was sealed in a small container, about the size Read more about A colony of blue-green algae can power a computer for six months[…]
[…] In a recent paper published in Cell Reports Physical Science, they demonstrated how freezing and thawing a molten salt solution creates a rechargeable battery that can store energy cheaply and efficiently for weeks or months at a time. […] Most conventional batteries store energy as chemical reactions waiting to happen. When the battery is Read more about Rechargeable Molten Salt Battery Freezes Energy in Place for Long-Term Battery Storage[…]
In December 2021, 27,591 aircraft took off or landed at Frankfurt airport—890 every day. But this winter, many of them weren’t carrying any passengers at all. Lufthansa, Germany’s national airline, which is based in Frankfurt, has admitted to running 21,000 empty flights this winter, using its own planes and those of its Belgian subsidiary, Brussels Read more about Thousands of Planes Are Flying Empty and No One Can Stop Them[…]
Engineers at the University of Illinois Chicago have built a cost-effective artificial leaf that can capture carbon dioxide at rates 100 times better than current systems. Unlike other carbon capture systems, which work in labs with pure carbon dioxide from pressurized tanks, this artificial leaf works in the real world. It captures carbon dioxide from Read more about Stackable artificial leaf uses less power than lightbulb to capture 100 times more carbon than other systems[…]
[…] the pilot system demonstrates an important possible source of carbon-neutral fuel for industries struggling to decarbonise, such as aviation and shipping, which currently contribute around 8 per cent of total carbon dioxide emissions attributed to human activity. But, producing 32 millilitres of methanol in a typical seven-hour-day run, the current proof of concept will Read more about Swiss lab’s rooftop demo makes fuel from sunlight and air[…]

[…] while the EV battery recycling industry is starting to take off, getting carmakers to use recycled materials remains a hard sell. “In general, people’s impression is that recycled material is not as good as virgin material,” says Yan Wang, a professor of mechanical engineering at Worcester Polytechnic Institute. “Battery companies still hesitate to use Read more about Study: Recycled Lithium Batteries as Good as Newly Mined[…]
To make the transition to low-carbon energy sources and address climate change we need open data on the global energy system. High-quality data already exists; it is published by the International Energy Agency. But despite being an international institution that is largely publicly funded, most IEA data is locked behind paywalls. This makes it unusable Read more about The International Energy Agency publishes the detailed, global energy data we all need, but its funders force it behind paywalls. Let’s ask them to change it.[…]
In late September, Carbios, a French startup, opened a demonstration plant in central France to test this idea.
