Technology designed in the 1800s may be the key to unlocking the future of EV batteries: ‘A savior in the EV market’

Posted by in categories: chemistry, energy

While the chemistry is different from traditional lithium-ion batteries, it’s part of a power pack with big advantages, including greater energy storage (estimated at up to 15 times that of lithium-ion) in relation to mass, a metric referred to as energy density.

Other perks include easy recyclability, being planet-friendly, and being cost-effective, per the ET report, which was written with benefits to the Indian market in mind.

“It is a long-range, budget-friendly, lightweight, and recyclable source of energy that can arguably be a saviour in the EV market,” Kriti Saraiya wrote for ET.

Graphene proton transport could revolutionize renewable energy

Posted by in categories: energy, sustainability

Graphene’s atomically thin structure makes it impenetrable to a variety of elements, including protons. However, graphene’s edges, flaws, and functionalization can open up channels for proton diffusion. Temperature, humidity, and the existence of functional groups are some of the variables that affect the flow of protons in graphene.

ChargePoint Introduces New 500 kW Ultra-Fast DC Charging System

Posted by in category: energy

ChargePoint announced today the first large-scale deployment of its all-new Express Plus Power Link 2000 DC fast charging platform, which is capable of delivering charging speeds up to 500 kilowatts.

The hardware and associated software of the Power Link system debuted today at the all-new Mercedes-Benz HPC NA fast charging network, which due to the high power output, is being called “the fastest public charging network in North America.”

Let’s recall that the Mercedes-Benz HPC NA will be a premium DC fast charging network for all EVs, consisting of up to 400 sites (and over 2,500 chargers) by 2030. Some of the stations will be installed at Simon Property Group’s locations (at least 55) and Buc-ee’s chain of travel centers (about 30 sites).

The Next Leap in Battery Tech: Lithium-Ion Batteries Are No Longer the Gold Standard

Posted by in categories: energy, sustainability, transportation

Lithium metal, chosen for battery anodes due to its superior energy density compared to other materials, is a smart choice. Yet, challenges arise at the interface between the electrode and the electrolyte, presenting opportunities for enhancement to achieve safer and more efficient performance in future applications.

Researchers from Tsinghua University are keen on replacing the graphite anode with a lithium metal anode to construct a battery system with higher energy density. However, the Li metal anode is unstable and readily reacts with electrolytes to form a solid-electrolyte interphase (SEI). Unfortunately, the natural SEI is brittle and fragile, resulting in poor lifespan and performance.

Here, the researchers have looked into a substitute for natural SEI, which could effectively mitigate the side reactions within the battery system. The answer is ASEI: artificial solid electrolyte interphase. ASEI corrects some of the issues plaguing the bare lithium metal anode to make a safer, more reliable, and even more powerful source of power that can be used with more confidence in electric vehicles and other similar applications.

Vanishing Act for Water Waves

Posted by in categories: energy, mathematics

Cavities at the sides of a water channel can cause waves to be completely absorbed, suggesting new techniques for protecting coastlines.

If waves of water, light, or sound were to impinge upon a hypothetical object called a perfect absorber, they would be neither reflected nor transmitted; they would simply vanish. Researchers have now demonstrated perfect absorption using ordinary water waves traveling down a narrow channel [1]. The waves are canceled out by their own reflections from cavities built into the side of the channel. With further development, the researchers believe that the effect could be used to reduce erosion or protect sensitive structures by using an array of elements deployed near coastlines.

“We were motivated by the need to control or absorb waves in rivers or to protect coastlines,” says mathematical physicist Agnes Maurel of ESPCI Paris. “Completely absorbing wave energy is even better than redirecting it, and you can also imagine perhaps harvesting such energy.”

Mercedes-Benz launches first EV charging hub in US with 400kW piles from ChargePoint

Posted by in categories: energy, finance, sustainability

Eleven months after sharing plans to develop and implement a new series of EV charging hubs across North America, Mercedes-Benz, with the help of ChargePoint, has opened its very first location in the US, complete with a driver lounge and powered using 100% renewable energy.

This past January, Mercedes-Benz announced plans for the new network of fast charging hubs during a press conference at CES alongside its new partner, ChargePoint.

At the time, we learned that both MN8 Energy and Mercedes-Benz would finance and jointly operate the network of over 400 planned charging hubs, becoming home to over 2,500 ChargePoint DC fast charging piles across the US and Canada.

Airloom’s device promises utility-scale wind energy at 1/3 the cost

Posted by in categories: energy, sustainability

It’s worth noting that Airloom’s new wind turbine can be configured vertically or horizontally and that it can be deployed offshore as well as on land.

“For decades, the wind industry has lowered the cost of energy production by scaling ever larger turbines. Although this has been extremely successful in driving down overall costs, the approach now faces challenges in terms of both siting and cost of materials,” said Carmichael Roberts of Breakthrough Energy Ventures in a press release. “Airloom’s unique approach can solve both these problems, opening new market opportunities for wind energy that will further drive down costs. We look forward to Neal’s leadership in bringing this revolutionary technology into the market.”

With small-scale prototypes already up and running, the company plans to use its seed funding for research and development of the Airloom wind energy test device, which is designed to produce 50 kilowatts (kW) of electricity. Future systems are expected to be megawatt-scale and deployed hundreds of megawatts at a time in utility-scale wind farms.

Hydrogen fuel could change the way aircraft work, and look

Posted by in categories: energy, transportation

Switching to hydrogen would mean big changes to the aviation industry, and possibly cleaner aircraft. But it would require major adjustments.
