Hydrogen, often hailed as the ‘fuel of the future,’ emerges as a compelling alternative to traditional fossil fuels due to its clean combustion, emitting only heat and water. However, the current methods of hydrogen production, predominantly reliant on gas or coal, contribute significantly to CO2 emissions. Enter ‘white’ hydrogen, a natural and potentially game-changing discovery that has surfaced in various locations worldwide, offering a cleaner and more economical alternative. Could this be the solution to Europe’s energy crisis?

Understanding White Hydrogen

While hydrogen is abundant in various forms on Earth, the existence of large quantities of pure hydrogen gas was not previously recognized. The accidental discovery of nearly pure natural hydrogen in Mali in 2012 sparked interest in exploring this untapped resource. Geologists have since been investigating the extraction of ‘white’ hydrogen, believed to form through water-mineral reactions beneath the Earth’s surface. Unlike fossil fuel deposits that take millions of years to form, natural hydrogen is continuously replenished, presenting a potentially sustainable and cleaner energy source.

In a significant leap towards enhancing offshore wind energy, a groundbreaking turbine technology is poised to undergo testing in Norway. The 19-meter (62-foot) 30-kilowatt contra-rotating vertical-axis turbine represents a prototype of a design capable of reaching unprecedented sizes and power levels. While traditional wind turbines feature a propeller-on-a-stick design, this new technology offers an alternative that could potentially cut the costs of offshore wind energy production in half.

Current wind turbine designs, when scaled up for offshore use, present engineering challenges. These challenges stem from the concentration of heavy components at the top of the structure, leading to increased complexity and expenses in constructing and maintaining floating platforms to withstand turbulent ocean conditions.

This week marks a significant milestone for the heat-battery industry as California-based startup Antora Energy reveals plans to establish its first large-scale manufacturing facility in San Jose. With an established track record in producing modular heat batteries, this new factory promises to substantially boost production capacity, potentially catalyzing the transition of heavy industries away from fossil fuels. While my recent Tech Review article covered the announcement in depth, today’s newsletter delves into the broader implications of Antora’s breakthrough and the industry as a whole.

When discussing decarbonization, the focus often centers on electrifying everyday activities, such as transitioning to electric vehicles and induction cooktops, and upgrading heating systems. However, a significant portion of global carbon emissions arises from less conspicuous sources: industrial manufacturing processes that require exceptionally high temperatures, often exceeding 1,000 or even 1,500 degrees Celsius.

In a groundbreaking study, two of humanity’s most enduring materials, cement, and carbon black, are poised to usher in a cost-effective energy storage system. This novel technology holds the potential to support the utilization of renewable energy sources such as solar, wind, and tidal power by ensuring the stability of energy networks, even in the face of fluctuating renewable energy supplies.

The research reveals that these two materials, when combined with water, can yield a supercapacitor—a viable alternative to traditional batteries—for storing electrical energy. MIT researchers leading the project envision that these supercapacitors could be seamlessly integrated into various applications. For instance, they propose embedding them within the concrete foundation of a house, where they could accumulate an entire day’s worth of energy without significantly increasing construction costs, all while maintaining structural integrity. The researchers also envision concrete roadways that provide wireless recharging capabilities for electric vehicles as they traverse these roads.

Westinghouse, a U.S. company, has announced its plans to introduce a small modular reactor (SMR) to generate clean electricity that could potentially replace coal plants or power water desalination and other industries. The reactor, known as the AP300, is planned to have a 300 MW capacity and will not use special fuels or liquid metal coolants, making it a simpler and safer design compared to some other next-generation reactors. This SMR is expected to be a smaller version of its successful AP1000 reactor, which is already in operation in China and is being ramped up in Georgia at the Vogtle plant.

According to Rita Baranwal, Westinghouse Electricity Co’s top technology officer, the company plans to start constructing the reactor by 2030 and have it running by 2033. Despite facing obstacles for new nuclear projects, Baranwal expressed confidence, stating that the company has kept the design simple and based it on demonstrated and licensed technology, which is one of the advantages of this concept.

University of Rochester scientists have made a significant breakthrough by developing a superconducting substance that is suitable for practical use at low temperatures and pressures, marking a historic accomplishment.

Scientists at the University of Rochester have made a groundbreaking discovery in the field of superconductivity. Their research has resulted in the creation of a room-temperature superconductor, a material that can conduct electricity with zero resistance at temperatures as high as 59 degrees Fahrenheit (15 degrees Celsius).

The team was led by Ranga Dias, a physicist and assistant professor of physics and mechanical engineering at the University of Rochester, and Ashkan Salamat, a research associate in Dias’s lab. Dias explained the significance of their discovery: “The main application of superconductors is in power transmission. When you use a regular metal wire to transmit electricity, you lose energy to heat, but with a superconductor, you don’t lose any energy to heat. It’s all electricity that’s transmitted.”

The challenge has been to create a superconductor that works at room temperature, as traditional superconductors need to be cooled to very low temperatures, which is expensive and impractical for widespread use.

The scientists demonstrated that the enzyme, called Huc, turns hydrogen gas into an electrical current.

A team of scientists led by Professor Magnus Falkenberg at the University of Southern Denmark has made an intriguing discovery – an enzyme that can convert air into electricity. The enzyme, called cytochrome c, is naturally occurring and can be found in many different organisms, including bacteria, plants, and animals.

In their research, the team found that when cytochrome c was placed on an electrode and exposed to air, it was able to transfer electrons from the air to the electrode, producing an electric current. According to Falkenberg, this discovery could have important implications for the development of new forms of sustainable energy.

“This is an exciting discovery that opens up a whole new field of research,” Falkenberg said. “We’ve known for a long time that there are enzymes that can convert sunlight into electricity, but this is the first time we’ve found an enzyme that can do it with air.”

In the future, a room could start charging your phone as soon as you enter it.

A new wireless charging system uses harmless infrared light to power devices from nearly 100 feet away — putting us one step closer to truly wireless technology.

The challenge: Wireless charging isn’t new — you might already own a coaster-shaped wireless charging pad for your smartphone or watch.

However, those wireless chargers typically require your device to remain very close to the charger and stationary — pick it up, and the charging stops. Plus, the chargers still require power cords themselves, meaning they don’t exactly help declutter your living or working spaces.

The system is already powerful enough for sensors and could charge mobile devices with further development.

Researchers have started developing technologies that charge devices over the air — these could be used to turn entire rooms into wireless chargers, meaning your device would start powering up as soon as you entered.

However, many wireless charging prototypes require that the entire room be modified, which isn’t terribly practical.

Others only work over distances of a few meters — that prevents their use in larger spaces, such as factories, where wireless power could eliminate cords that pose a safety hazard.

A sustained, stable experiment is the latest demonstration that nuclear fusion is moving from being a physics problem to an engineering one.

A nuclear fusion reaction has lasted for 30 seconds at temperatures in excess of 100 million°C. While the duration and temperature alone aren’t records, the simultaneous achievement of heat and stability brings us a step closer to a viable fusion reactor – as long as the technique used can be scaled up.

Most scientists agree that viable fusion power is still decades away, but the incremental advances in understanding and results keep coming. An experiment conducted in 2021 created a reaction energetic enough to be self-sustaining, conceptual designs for a commercial reactor are being drawn up, while work continues on the large ITER experimental fusion reactor in France.

Now Yong-Su Na at Seoul National University in South Korea and his colleagues have succeeded in running a reaction at the extremely high temperatures that will be required for a viable reactor, and keeping the hot, ionised state of matter that is created within the device stable for 30 seconds.
