Super-Fast, Long-Life Rechargeable Battery

An international group of researchers has demonstrated an aqueous zinc battery with excellent performance in terms of capacity, rate capability, specific energy, and output voltage. The battery is a hybrid supercapacitor-battery hybrid device which has demonstrated an unprecedented cycling stability of 99.2% capacity retention after 17,000 cycles at 100% depth of discharge.

This battery technology has been explored as a promising alternative due to its low cost, safety, environmental friendliness, and intrinsic non-flammable nature. However, their widespread adoption has been held back by their low Coulombic efficiency (The Coulomb efficiency is usually used to describe the released battery capacity. It refers to the ratio of the discharge capacity after the full charge and the charging capacity of the same cycle) and the notorious dendritic growth (dendrites are basically whiskers of minerals that grow inside batteries and can cause the devices they’re powering to lose power more quickly, short out, or in some instances, catch fire ) at the zinc-based anodes, along with the fast capacity fading of the cathodes.

Functional Miniature Hydrogen Fuel Cell Powers RC Truck

Hydrogen fuel cells are still a bit mysterious and likely are unattainable in the near future, but you can actually buy them right now, whether in vehicles or as parts. To demonstrate how practical they are, Alfonso Delgado Ollero built a miniature hydrogen fuel cell to power an RC truck.

The practical concerns of producing the hydrogen in the first place and the energy density being relatively low are relevant when talking about the future of the automotive industry, but according to Alfonso Delgado Ollero, they shouldn’t prevent makers from experimenting with hydrogen fuel cells.

With the exception of 2022 (+7.6%), Battery Electric as a power source is expected to grow between 10% and 17% throughout the forecast period, while ICE growth rates start the period at -2.3% and then grow at less than 1% for 2023 to 2025.

Battery Electric is expected to grow from 12.8% of the market in 2022 to 21.2% by 2027, while during the same period ICEs are expected to decline from 85% of the market to 75%.   PSR

Can EV Enthusiasm Trigger Global Growth?

Consumer adoption of EVs has gathered momentum this year, spurred by higher global oil prices. The Russia-Ukraine war has made EVs suddenly more appealing to many car buyers, accelerating adoption globally. The higher oil prices are driving EVs closer to cost parity with internal combustion engine (ICE) vehicles. In Bloomberg New Energy Finance’s most recent Electric Vehicles Outlook 2022 report, it projected EV sales to hit 20.6 million units by 2025.

On Tesla’s most recent earnings call, Elon Musk admitted, “We do not have a demand problem but a production problem.” Other car manufacturers such as Ford, for instance, says it can build its F150 Lightning and the Mustang Mach E fast enough to keep up with demand

Cummins Jumps On New Energy Storage Iron Salt Formula

Cummins $24 million stake in the startup VoltStorage gives them a foot in the door with new iron redox flow technology. There is nothing wrong with lithium-ion energy storage but global demand for energy storage has nowhere to go but up, and so are lithium prices. While lithium is relatively abundant in the ground, but current supply is falling behind demand. At the same time, lithium extraction is messy and has significant environmental impact, causing local opposition to new mines and other facilities which could stall development. Aside from accessing a recyclable supply chain that can avoid conflict issues, flow battery fans note a long list of advantages over lithium-ion technology including lower cost, longer duration, and ease of scalability

PSR Analysis: Cummins has been making investments into EVs (such as the purchase of Brammo in 2017 and Meritor in 2022) for some time and this low cost, long duration, grid scale energy storage battery is part of their plan. This diversifies their portfolio of alternative power systems and helps them in the gid scale storage market. One of the major advantages for flow batteries is that they aren’t lithium-based and are therefore not subject to the same massive and sustained price increases that lithium material is seeing. PSR

EV Shipping Set To Blow IC Engines Out of the Water

ALTERNATIVE POWER REPORT

Researchers from the University of California, Berkeley, and Lawrence Berkeley National Laboratory have released a study which examines “the technical outlook, economic feasibility, and environmental impact of battery-electric containerships.” By modelling 5 to 10 GWh electrified containerships, they found that 40% of routes today could be electrified in an economically viable manner, before considering environmental costs.

Using only technology available for purchase today, nearly all ships with routes shorter than 2,000 kilometres are economically advantageous, and ships with routes as long as 3,000km are economically viable.

Source: PV Magazine Read The Article

PSR Analysis: Ships transport more than 10 billion metric tons of cargo each year, including clothing, electronics, and oil, and almost all of these ships run on fossil fuels, so they emit a lot of carbon pollution. Maritime shipping causes about 3% of global greenhouse gas emissions. As the costs of large ICE containerships continue to rise electrified containerships become increasingly cost effective. Electrified containerships are 80% more efficient than their ICE counterparts, and use 30% less energy overall.    PSR

Festive Demand Expected To Boost Auto Industry

INDIA REPORT 
Aditya Kondejkar

Adequate rainfall across the country along with the start of the long festive season will keep the demand for automobiles positive and help keep the momentum going in this segment. Additionally, normal monsoons in most parts of the country resulting in a decent agricultural harvest kept demand positive. So, automakers are focusing on building up inventory in anticipation of higher demand

The Indian economy is poised to shrug off the modest tapering of growth in Q1 2022, and aggregate demand is firm and set to expand as the festival season sets in. Hatchback cars and affordable, non-electric motorcycles and scooters are set to register bumper sales in the coming months as India gets ready to celebrate its first ‘normal’ festive season after a gap of two years. Above-normal rains, positive consumer sentiment and a generally optimistic mood are also expected to boost sales of these entry-level vehicles.

Vinfast To Export Initial 5,000 EVs To Europe and the U.S.

SOUTHEAST ASIA: VIETNAM REPORT

Vinfast has announced plans to export approximately 5,000 EVs to the U.S., Canada, and Europe by the end of 2022. This is the first time for them to export EVs. The company also plans to start construction of a new EV plant in the U.S. by the end of this year, accelerating its global strategy.

According to the plan, exports to the U.S. and other countries will begin in early November, with delivery to customers starting in December. Vinfast’s CEO revealed that the company has orders for approximately 65,000 EVs worldwide.

South Korea Sees First Trade Deficit with China in 28 Years

FAR EAST: SOUTH KOREA REPORT

The economic relationship between China and the ROK has reached a turning point. According to statistics from the ROK, for the first time in 28 years, the ROK has a trade deficit with China. China has been the best customer of the export driven ROK economy, and this is causing concern in the ROK. At the same time, Chinese companies are intensifying their takeover of Korean companies, and in response to the escalation of the U.S.-China conflict, they have begun to pursue a strategy of using Korea as a foothold to capture the U.S. market.

A management official at South Korea’s Hyundai Motor’s joint venture plant in Chongqing, China, said that the passenger car assembly plant is idle and that negotiations are underway to sell it to a Chinese company. Hyundai Motor started operations in Chongqing in 2017, including an assembly plant with an annual production capacity of 300,000 units, but sales slumped due to the rise of Chinese automakers. At one point, the company occupied second place with a market share of nearly 10%, but recently it has fallen below 2% and slumped to 10th place.
