Can we morph cities into energy farms? We sure can now! This turbine catches wind from any direction and generates clean energy, even in dense urban areas!
When it comes to the semiconductor industry, silicon has reigned as king in the electronics field, but it is coming to the end of its physical limits.
To more effectively power the electrical grid, locomotives and even electric cars, Lawrence Livermore National Laboratory (LLNL) scientists are turning to diamond as an ultra-wide bandgap semiconductor.
Diamond has been shown to have superior carrier mobility, break down electric field and thermal conductivity, the most important properties to power electronic devices. It became especially desirable after the development of a chemical vapor deposition (CVD) process for growth of high-quality single crystals.
There they go again. Just a few months ago the US Department of Energy tapped a startup called Group14 Technologies for a multi-million dollar R&D grant to usher in a new generation of high performance EV batteries, and now here comes Group14 with another $17 million in series B funding spearheaded by the South Korean battery expert SK Materials. If you guessed that means scaling up production for the mass market, you’re right on the money. The bigger question is why the Energy Department is determined to support the US electric vehicle industry, considering that White House policy has been aimed at supporting the US oil industry. Any guesses?
Even Apple wants to get into the automobile business it seems.
(Reuters) — Apple Inc is moving forward with self-driving car technology and is targeting 2024 to produce a passenger vehicle that could include its own breakthrough battery technology, people familiar with the matter told Reuters.
The iPhone maker’s automotive efforts, known as Project Titan, have proceeded unevenly since 2014 when it first started to design its own vehicle from scratch. At one point, Apple drew back the effort to focus on software and reassessed its goals. Doug Field, an Apple veteran who had worked at Tesla Inc, returned to oversee the project in 2018 and laid off 190 people from the team in 2019.
Hydrogen is a sustainable source of clean energy that avoids toxic emissions and can add value to multiple sectors in the economy including transportation, power generation, metals manufacturing, among others. Technologies for storing and transporting hydrogen bridge the gap between sustainable energy production and fuel use, and therefore are an essential component of a viable hydrogen economy. But traditional means of storage and transportation are expensive and susceptible to contamination. As a result, researchers are searching for alternative techniques that are reliable, low-cost and simple. More-efficient hydrogen delivery systems would benefit many applications such as stationary power, portable power, and mobile vehicle industries.
Now, as reported in the journal Proceedings of the National Academy of Sciences, researchers have designed and synthesized an effective material for speeding up one of the limiting steps in extracting hydrogen from alcohols. The material, a catalyst, is made from tiny clusters of nickel metal anchored on a 2-D substrate. The team led by researchers at Lawrence Berkeley National Laboratory’s (Berkeley Lab) Molecular Foundry found that the catalyst could cleanly and efficiently accelerate the reaction that removes hydrogen atoms from a liquid chemical carrier. The material is robust and made from earth-abundant metals rather than existing options made from precious metals, and will help make hydrogen a viable energy source for a wide range of applications.
“We present here not merely a catalyst with higher activity than other nickel catalysts that we tested, for an important renewable energy fuel, but also a broader strategy toward using affordable metals in a broad range of reactions,” said Jeff Urban, the Inorganic Nanostructures Facility director at the Molecular Foundry who led the work. The research is part of the Hydrogen Materials Advanced Research Consortium (HyMARC), a consortium funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy Hydrogen and Fuel Cell Technologies Office (EERE). Through this effort, five national laboratories work towards the goal to address the scientific gaps blocking the advancement of solid hydrogen storage materials. Outputs from this work will directly feed into EERE’s H2@Scale vision for affordable hydrogen production, storage, distribution and utilization across multiple sectors in the economy.
Inside these walls, scientists have been trying for decades to create an unlimited source of energy, nuclear fusion. Welcome to JET, the world’s biggest nuclear fusion experiment.
Scientists argue that fusion could replace coal gas and nuclear fission in the energy mix alongside renewable energy, which can prove to be unreliable. If we can learn to control it, nuclear fusion could change life as we know it. But that’s a big if.

It seems competition is increasing.
BEIJING – In a future driven by electric vehicles, China is poised to dominate if the U.S. does not transform its automobile industry in coming years.
While California-based Tesla captured popular attention for electric cars, national policy in Beijing encouraged the launch of several rivals in China, the world’s largest auto market. Already, sales of electric cars and other new energy vehicles hit a record in September in China. Even Tesla launched a factory there last year, and is planning to sell made-in-China cars to Europe.
Oak Ridge National Laboratory researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today’s lithium-ion batteries that power electric vehicles and consumer electronics.
The new class called NFA, which stands for nickel-, iron-and aluminum-based cathode, is a derivative of lithium nickelate and can be used to make the positive electrode of a lithium-ion battery. These novel cathodes are designed to be fast charging, energy dense, cost effective, and longer lasting.
With the rise in the production of portable electronics and electric vehicles throughout the world, lithium-ion batteries are in high demand. According to Ilias Belharouak, ORNL’s scientist leading the NFA research and development, more than 100 million electric vehicles are anticipated to be on the road by 2030. Cobalt is a metal currently needed for the cathode which makes up the significant portion of a lithium-ion battery’s cost.
India just laid the foundations for what officials are claiming will be the world’s largest renewable energy park. The gigantic project, in the Kutch region of western Gujarat, will cover an area of 180, 000 acres — an area roughly the size of Singapore, as Agence France-Presse reports.
Once finished, the park will produce 30 gigawatts of electricity from both wind turbines and solar arrays, thereby cutting carbon dioxide emissions by up to 50 million tons per year. For perspective, the protagonists in the 1985 film “Back to the Future” needed to generate a staggering 1.21 gigawatts of power to activate their time machine — and this new facility will produce more than 24 times that figure.
“The hybrid renewable energy park will be largest in the world and generate 30, 000 megawatts of power,” prime minister Narendra Modi said during the park’s official inauguration, according to AFP.

Google will use large batteries to replace the diesel generators at one of its data centers in Belgium, describing the project as a first step towards using cleaner technologies to provide backup power for its millions of servers around the world.
“Our project in Belgium is a first step that we hope will lay the groundwork for a big vision: a world in which backup systems at data centers go from climate change problems to critical components in carbon-free energy systems,” said Joe Kava, Vice President for Data Centers at Google. “We’re aiming to demonstrate that a better, cleaner solution has advanced far enough to keep the internet up and running.”
