According to IEA’s World Energy Outlook 2020, solar power is now the cheapest source of electricity. (Image Credit: American Public Power Association) The global response to the coronavirus pandemic could drastically change the future of energy. According to the International Energy Agency’s World Energy Outlook 2020, the world’s best solar power strategies provide the most affordable electricity in history. Currently, the technology costs less than gas and coal in most majo ...
New research suggests renewable energy is more efficient than nuclear power, while Western Australia plans to phase out coal-fired electricity with renewable energy. Renewable energy may be key in reducing fossil fuels. (Image credit: Getty Images)   Countries looking to lower emissions and reduce reliance on fossil fuels are turning to alternative energy sources, such as nuclear power. Though it's often promoted as one of the best ways to eliminate fossil fuels, new research suggests rene ...
This machine captures carbon dioxide in the air and converts it into methane fuel. It could be installed in offices, allowing workers to think more clearly. (Image Credit: Soletair)   Soletair Power, a Finnish start-up, developed an air filtration and purification system that captures carbon dioxide in the air and converts it into useable fuel. This system can be utilized in an office building, serving hundreds of people who work there. It was originally built for the 2020 World Expo in Du ...
By compressing simple molecule solids with hydrogen, the researchers create a new material that achieves superconductivity at room temperature. (Image credit: University of Rochester)   Researchers from the University of Rochester have created a new material that doesn't need to be super-cooled to achieve superconductivity. Above room temperature means anything above 320F, which is considered a fantastic feat in itself. In the researchers' case, they managed to attain a resistive-free flow ...
Researchers have developed a new process that converts plastic waste into hydrogen and carbon nanotubes. This could be used worldwide in an effort to reduce plastic pollution on land and in oceans, lakes, and rivers. (Image Credit: Antoine GIRET/Unsplash)   Plastic has become a major environmental problem over the past several decades. Today, 4.9 billion tons of plastic either sit in landfills or nature, a number that is projected to increase each year. Now, by using microwaves, chemists a ...
This circuit could be used to provide limitless, low-voltage, clean power for small devices or sensors. (Image Credit: University of Arkansas)   Physicists at the University of Arkansas have developed a circuit that utilizes graphene to produce unlimited clean energy. By capturing graphene's thermal motion, the circuit can convert it into an electrical current. This could be integrated into a chip, providing limitless, low-voltage, clean energy for small devices or sensors. The team publis ...
NuScale has received a final safety evaluation report for its small modular reactor. The reactor is capable of shutting itself off automatically in case of an emergency. (Image Credit: NuScale Power)   According to a statement, NuScale received a final safety evaluation report (FSER) from the US Nuclear Regulatory Commission for its small modular reactor. The reactor is a 76-foot tall, 15-foot wide steel cylinder that can generate 50 megawatts of electricity.   The design utilizes u ...
NDB states that its proof-of-concept battery can outlast lithium-ion batteries and won’t need to ever be recharged since it acts like a self-charging generator. It can last anywhere from 10 to 28,000 years. (Image Credit: NDB)   Wouldn’t it be amazing if batteries could seemingly last forever without a charge? Electronic devices such as smartphones, wearable tech, etc. that require a recharge after a day of constant use could benefit from this. Even EVs could potentially levera ...
The new pumped-hydro design leverages water to add more solar and wind power onto the grid. (Image Credit: NREL)   In a collaborative effort with the National Renewable Energy Laboratory (NREL) and other firms, Obermeyer Hydro Inc. designed a new pumped hydro system. The goal is to deploy the system in a time-efficient manner while cutting down on project costs and optimizing them for U.S. energy storage requirements. Obermeyer received a $1.18 million fund to develop the advanced closed-l ...
This patent can help solve thermal runaway issues in EV batteries. The mitigation solution involves combining a lithium-ion battery with a metal-air one to prevent it from catching fire. (Image Credit: USTPO)   Other than increasing energy density and decreasing battery costs, electric car manufacturers have one common goal: making their vehicles safer. One method involves safely mitigating thermal runaway, the most frequent cause of an EV catching fire and exploding. What happens is that ...
This liquid metal battery could replace lithium-ion batteries to provide power to hospitals, manufacturing facilities or a subdivision of several hundred homes. (Image Credit: MIT)   The problem with intermittency in non-fossil fuel electricity generation must be addressed before shifting towards a fully renewable energy-based economy. To help solve this issue, Donald Sadoway and his team at MIT developed a liquid metal battery that can be used for stationary energy storage. The goal was t ...
An image taken by a scanning electron microscope reveals a single-crystal gold nanowire on a thermal oxide substrate. (Image Credit: Natelson Research at GroupRice University) Utilizing an advanced optical detection system, researchers at Rice University have discovered that electricity generated from temperature differences isn’t affected by grain boundaries positioned in its way in nanoscale gold wires. However, this thermoelectric response can be altered by strain and other defects i ...
