Scientists Discover Enzyme That Can Turn Air Into Electricity

Posted by in categories: energy, sustainability, transportation

In an exciting turn for the field of sustainable energy research, Australian scientists have found a way to make energy out of thin air. Literally.

As detailed in a new study published this week in the journal Nature, researchers from Monash University in Melbourne, Australia discovered a new bacterial enzyme that transforms the traces of hydrogen in our atmosphere into electricity, technology that could one day be used in fuel cells that power anything from a smartwatch to even a car.

“We’ve known for some time that bacteria can use the trace hydrogen in the air as a source of energy to help them grow and survive, including in Antarctic soils, volcanic craters, and the deep ocean,” said Professor Chris Greening, a contributor to the study, in a statement.

This 1,000-foot Multi-Rotor Floating Turbine Can Power 80,000 Homes

Posted by in categories: energy, sustainability

A Norwegian Greentech company has recently unveiled its new 1,000-foot (324m) tall, floating wind turbine array. Called “Wind Catcher”, this innovation in renewable energy generation could be used to power as many as 80,000 homes.

The system has been developed by the Norwegian-based Wind Catching Systems (WCS), who declare that their new wind turbine setup could generate five times the annual energy of the world’s biggest standalone wind turbines. Not only that, but if scaled, it could reduce the costs of wind energy to be competitive with traditional grid-supplied electricity.

New Superconducting Material Could Transform Electronics — If It Works

Posted by in categories: energy, materials

Superconductivity is an incredible property of certain materials with exciting consequences. Once reached, for example, said materials can conduct electricity without resistance, so no loss of energy. But most materials are superconductive at extremely low temperatures. The quest for a room-temperature superconductor is ongoing, and is not without a bit of scientific drama.

A few years ago, there was a claim of a room-temperature superconductor that became supercritical at a temperature of 15°C (59°F), but required a pressure of 2.5 million atmospheres. That’s on the order of the pressure you might find in the core of a rocky planet, and can be achieved by squeezing materials between two diamonds. Other scientists raised issues with the way the numbers were handled, including an accusation of the data used being fabricated.

The paper was retracted by the journal Nature last September, and the team claims they are ready to resubmit that work. They have also announced a brand-new material with even more extraordinary properties (if confirmed). The new substance is described as a nitrogen-doped lutetium hydride that becomes superconductive up to 20.5°C (69°F) and at a much lower pressure, roughly 10,000 atmospheres. Quite the improvement.

A Hardy Enzyme May Hold Key to Creating Power Out of Thin Air

Posted by in categories: energy, innovation

A recent scientific breakthrough could see electricity being generated using nothing but the atmosphere, with perhaps a little added hydrogen.

The process involves an enzyme made by bacteria to help them grow and survive in environments including volcanic craters and Antarctica. The enzyme, called Huc, has been found to produce a small electrical current by consuming hydrogen in the air as a source of energy, researchers said in a paper published Wednesday in scientific journal Nature.

First gas turbine powered by pure hydrogen

Posted by in category: energy

University of Stavanger operates a micro gas plant in south-west Norway. The gas turbine produces both heat and electricity. It also supplies hot water for heating the laboratory buildings in the immediate area. In addition, surplus energy is supplied to power provider Lyse’s district heating and electricity grids. All energy is used efficiently.

The researchers have been working on developing a method for using pure hydrogen as fuel in the gas turbine. The goal is to produce electricity with zero CO2 emissions. In mid-May 2022, an important milestone was reached. They started running the turbine on 100 percent hydrogen.

Researchers at the University of Stavanger (UiS) have managed to run a gas turbine on 100 percent hydrogen.
