Clearing the air: Wind farms more land efficient than previously thought      (via sciencedaily.com)     Original source 

Wind power is a source of energy that is both affordable and renewable. However, decision-makers have been reluctant to invest in wind energy due to a perception that wind farms require a lot of land compared to electric power plants driven by fossil fuels. Research was based on the assessment of the land-use of close to 320 wind farms in the U.S. paints a very different picture.

Nanoscale movies shed light on one barrier to a clean energy future      (via sciencedaily.com)     Original source 

New research is shedding light on one barrier to a clean energy future: corrosion. Using nanoscale imaging techniques, researchers have captured high-resolution videos of tiny crystals of ruthenium dioxide -- a key ingredient used to produce clean-burning hydrogen -- as they are eaten away by their acidic environment. The research could pave the way to more durable catalysts and dramatically extend the lifetime of devices needed to turn hydrogen green.

Discovering exceptional oxide ion conductivity at lower temperatures      (via sciencedaily.com)     Original source 

Oxide ion conductors used in solid-state fuel cells often fail to reach full potential when operating at temperatures below 500 degrees Celsius, but researchers have recently found a solution to this problem. They demonstrated high conductivity and stability in bismuth-containing Sill n oxyhalides with triple fluorite-like layers.

Subterranean storage of hydrogen      (via sciencedaily.com)     Original source 

Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.

A smarter city skyline for flood safety      (via sciencedaily.com)     Original source 

With climate change and rising urbanization, the likelihood and severity of urban flooding are increasing. But not all city blocks are created equal. Researchers investigated how urban layout and building structures contribute to pedestrian safety during flooding. Based on their simulated results, the team recommends modifying building corners and protective block layouts to reduce pedestrian risk.

Engineers 'symphonize' cleaner ammonia production      (via sciencedaily.com)     Original source 

Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the high temperatures and energy needed to manufacture it. But by improving on a well-known electrochemical reaction and orchestrating a 'symphony' of lithium, nitrogen and hydrogen atoms, engineers have developed a new ammonia production process that meets several green targets.

Nuclear fusion, lithium and the tokamak: Adding just enough fuel to the fire      (via sciencedaily.com)     Original source 

Building upon recent findings showing the promise of coating the inner surface of the vessel containing a fusion plasma in liquid lithium, researchers have determined the maximum density of uncharged particles at the edge of a plasma before certain instabilities become unpredictable. The research includes observations, numerical simulations and analysis from their experiments inside a fusion plasma vessel called the Lithium Tokamak Experiment-Beta (LTX- ). This is the first time such a level has been established for LTX- , and knowing it is a big step in their mission to prove lithium is the ideal choice for an inner-wall coating in a tokamak because it guides them toward the best practices for fueling their plasmas.

Heat, cold extremes hold untapped potential for solar and wind energy      (via sciencedaily.com)     Original source 

Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A study found that widespread, extreme temperature events are often accompanied by greater solar radiation and higher wind speeds that could be captured by solar panels and wind turbines. The research, which looked at extensive heat and cold waves across the six interconnected energy grid regions of the U.S. from 1980-2021, also found that every region experienced power outages during these events in the past decade. The findings suggest that using more renewable energy at these times could help offset increased power demand as more people and businesses turn on heaters or air conditioners.

Harnessing hydrogen at life's origin      (via sciencedaily.com)     Original source 

A new report uncovers how hydrogen gas, the energy of the future, provided energy in the past, at the origin of life 4 billion years ago. Hydrogen gas is clean fuel. It burns with oxygen in the air to provide energy with no CO2. Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is good fuel for as long as there has been life on Earth. Hydrogen is ancient energy.
