In order to enhance the accessibility of hydrogen-powered vehicles and establish hydrogen as a viable energy source, it’s imperative to reduce the cost of hydrogen production, thereby achieving economic feasibility. To achieve this goal, maximizing the efficiency of electrolysis-hydrogen evolution, the process responsible for producing hydrogen from water, is crucial.

Recently, a team of researchers comprising Professor In Su Lee, Research Professor Soumen Dutta, and Byeong Su Gu from the Department of Chemistry at Pohang University of Science and Technology (POSTECH) achieved a significant improvement in production efficiency of hydrogen, a green energy source, through the development of a platinum nanocatalyst. They accomplished this feat by depositing two different metals in a stepwise manner.

The findings of their research were published in Angewandte Chemie.

A recent press release from the Public Utility Commission of Texas (PUCT) has revealed that Tesla will be providing Virtual Power Plant (VPP) services to the state’s grid. The program is part of the Aggregate Distributed Energy Resource (ADER) project that the PUCT pushed last year.

With the VPP in place, Texas could now evaluate how consumer-owned small energy devices, such as home battery units, can be virtually aggregated to provide grid-scale services. Similar programs have been launched by Tesla in California and Australia, to much success.

As per the PUCT’s press release, the two ADERs that are launching the initiative involve Tesla Electric customers who have Powerwall batteries in their homes. The participants of the program have agreed to sell their surplus power in the ERCOT market, and will be compensated for doing so. One ADER is comprised of Houston-area CenterPoint Energy customers, while the other is comprised of Dallas-area customers served by Oncor Electric Delivery Company.

The world’s first wind-powered cargo ship has set off on her maiden voyage, using her giant metal ‘wings’ to fly through the ocean.

The WindWings have been fitted onto Mitsubishi-owned Pyxis Ocean — chartered by Cargill — and was designed by a team of British Olympic sailors.

It’s been built by Yara Marine Tech, and the WindWings are expected to save up to 30 percent of shipping fuel on average.

Researchers use a mix of less expensive, safer, and sustainably available components to create long-lasting bi-functional air electrodes.

We have all heard the line; the future is electric. But are we fully equipped to handle a full-scale transition to all-electric power? One thing standing in the way is the lack of cleaner and more affordable battery technologies to store energy.

Compared to commonly used Lithium-ion cells facing challenges related to cost, finite resources, and safety concerns, rechargeable zinc-air batteries (ZABs) are pitched as cost-effective energy storage devices and display high-energy density, especially for application in EVs.

Flexible polymers made with a new generation of the Nobel-winning “click chemistry” reaction find use in capacitors and other applications.

Society’s increasing demand for high-voltage electrical technologies – including pulsed power systems, cars, electrified aircraft, and renewable energy applications – requires a new generation of capacitors that store and deliver large amounts of energy under intense thermal and electrical conditions.

A new polymer-based device that efficiently handles record amounts of energy while withstanding extreme temperatures and electric fields has now been developed by researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Scripps Research. The device is composed of materials synthesized via a next-generation version of the chemical reaction for which three scientists won the 2022 Nobel Prize in Chemistry.

New, ground-breaking wind technology for the maritime industry has the potential to decarbonise large cargo vessels, which are currently responsible for about 2% of global emissions.

Superconductivity promises to transform everything from power grids to personal electronics. Yet getting the low-waste form of power to operate at ambient temperatures and pressures is proving to be easier said than done.

A discovery by a team of researchers from Emory University and Stanford University in the US could inform theories that might help us get around the stumbling blocks.

The finding involves what’s known as oscillating superconductivity. Typical superconductor behaviors involve electron partnerships called Cooper pairs moving through materials without losing significant amounts of energy in the form of heat.

A tiny little winged drone can soar with close to zero throttle, thanks to an impressive algorithm that responds to changing winds.

Dr Kathryn Mumford is an Associate Professor in the Department of Chemical Engineering at the University of Melbourne, specialising in separation processes in ion exchange, solvent absorption and solvent extraction technologies. In collaboration with industry, her recent research has pioneered a more efficient, greener process to produce lithium carbonate.

Dr Mumford leads the Sustainable Resources platform, which focuses on research to support the transition to green energy, reduce environmental impact and develop smart mining and processing. Here, she discusses how the platform is tackling the industry’s greatest challenges, and the role the sector will play in decarbonising the world.

I’ve been thinking about sustainability and environmental health throughout my whole career. I saw the consequence of waste and was compelled to develop ways to reduce its impact. My PhD was around environmental clean-up, specifically cleaning up tip sites and fuel spills at contaminated sites in Antarctica – I’ve since been back to Antarctica seven times on clean-up missions.
