Researchers advance fuel cell technology

Posted by in categories: bioengineering, chemistry, energy, nanotechnology, sustainability, transportation

Washington State University researchers have made a key advance in solid oxide fuel cells (SOFCs) that could make the highly energy-efficient and low-polluting technology a more viable alternative to gasoline combustion engines for powering cars.

Led by Ph.D. graduate Qusay Bkour and Professor Su Ha in the Gene and Linda Voiland School of Chemical Engineering and Bioengineering, the researchers have developed a unique and inexpensive nanoparticle catalyst that allows the to convert logistic liquid fuels such as gasoline to electricity without stalling out during the electrochemical process. The research, featured in the journal, Applied Catalysis B: Environmental, could result in highly efficient gasoline-powered cars that produce low carbon dioxide emissions that contribute to global warming.

“People are very concerned about energy, the environment, and global warming,” said Bkour. “I’m very excited because we can have a solution to the energy problem that also reduces the emissions that cause global warming.”

Water vapor in the atmosphere may be prime renewable energy source

Posted by in categories: climatology, sustainability

The search for renewable energy sources, which include wind, solar, hydroelectric dams, geothermal, and biomass, has preoccupied scientists and policymakers alike, due to their enormous potential in the fight against climate change. A new Tel Aviv University study finds that water vapor in the atmosphere may serve as a potential renewable energy source in the future.

The research, led by Prof. Colin Price in collaboration with Prof. Hadas Saaroni and doctoral student Judi Lax, all of TAU’s Porter School of the Environment and Earth Sciences, is based on the discovery that materializes in the interaction between and . It was published in Scientific Reports on May 6, 2020.

“We sought to capitalize on a naturally occurring phenomenon: electricity from water,” explains Prof. Price. “Electricity in thunderstorms is generated only by water in its different phases— , water droplets, and ice. Twenty minutes of cloud development is how we get from water droplets to huge electric discharges—lightning—some half a mile in length.”

The World’s First Open-Source Nuclear Reactor Blueprint Is Coming Online

Posted by in categories: climatology, nuclear energy, sustainability

To advance his vision, last week EIC launched the OPEN100 project, which Kugelmass says will provide open-source blueprints for the design, construction, and financing of a 100-megawatt nuclear reactor. He claims the reactor can be built for $300 million in less than two years, significantly decreasing the per-kilowatt cost of nuclear power.

“Nuclear power isn’t just part of the solution to addressing climate change; it is the solution,” Kugelmass said in a press release. “OPEN100 will radically change the way we deploy nuclear power plants going forward, offering a substantially less expensive and less complicated solution.”

The logic behind the idea is that the biggest barrier to the widespread use of nuclear is the cost of building reactors, which most experts would agree is a major problem for the industry. Kugelmass thinks that’s because we’ve been focused on large, overly complicated reactors that take far too long to build. His solution is to go back to tried and tested pressurized water reactors from the previous century, and bring their cost down even further through standardization and a focus on speedy construction.

Radio waves to beat pollution? Scientists are surprised

Posted by in category: sustainability

A Bangalore-based company claimed on Sunday that it had used radio frequency waves to lower air pollution over parts of Delhi, surprising sections of scientists who say they have never heard of such technology.

Devic Earth had installed devices that broadcast ultrahigh frequency (UHF) radio waves at two sites in the capital, responding to requests from Procam International, the organisers of the Delhi half-marathon, a Devic official said.

Company officials and the organisers have claimed the devices helped lower levels of tiny particulate matter (PM) in the air and served as a protective umbrella for the marathon runners. The devices used on Sunday were paid for by the organisers.

Yamaha unveils ‘extremely compact’ electric motors for e-motorcycles, cars

Posted by in categories: sustainability, transportation

When it comes to electric vehicles, Yamaha’s electric bicycle division has been charging into the future while its electric motorcycle division has been oddly quiet and unproductive — at least outwardly.

But now we’re getting a new look at a series of electric motors that Yamaha has been developing — motors that could rapidly progress Yamaha’s EV efforts.

First boat to make its own hydrogen fuel from seawater

Posted by in categories: robotics/AI, solar power, sustainability

Solar power, hydrogen fuel from seawater, automatic wingsails, a 6 year journey.


The Energy Observer set sail on a six-year world tour in 2017, testing new technologies, from onboard hydrogen electrolysis to fully-automated sails. It’s hoped the rugged ocean environment will prove the techs’ durability and usefulness at home.

New Perovskite Solar Cell Another Nail In Natural Gas Coffin

Posted by in categories: solar power, sustainability

Just a few years ago, low cost natural gas was the main force pushing coal out of the power generation market, and now low cost solar power is sneaking up on low cost natural gas. So far the competition is a trickle, not a flood. However, natural gas stakeholders don’t have much breathing room left, as indicated by the latest perovskite solar cell research.

Lithium metal batteries that perform well at low temperatures

Posted by in categories: climatology, sustainability

Lithium (Li) batteries, or lithium metal batteries, use metallic lithium as an anode. Over the past few decades, rechargeable Li batteries have been used to power a wide variety of electronic devices, including toys, portable consumer devices and electric vehicles.

While these batteries typically achieve reliable performances at room temperature, their , power and cycle life tend to decrease significantly at temperatures below −10 °C. The inability to function well at low temperatures is a crucial drawback, as it greatly limits their use in regions with particularly cold climates. The main reason for this limitation is that at temperatures below −10 °C the solid-electrolyte interphase (SEI) becomes unstable and leads to what is known as the dendritic Li plating of the anode in the batteries.

A team of researchers at Pennsylvania State University and Argonne National Laboratory recently introduced a new design for Li metal batteries that could overcome this well-documented drawback. The resulting batteries, presented in a paper published in Nature Energy, were found to perform remarkably well at low temperatures compared to previously developed Li batteries.
