The City of São Paulo has announced a partnership with Enel, an energy supplier, for its bus fleet electrification project to be completed by 2024. Under the agreement, the city will get funding for the project of R $ 8 billion. The plan calls for the replacement of the fleet of combustion buses with non-polluting models.
According to the city, Enel is one of the main stakeholders in the project and should assist companies in logistics, infrastructure and the feasibility of electric vehicles based on their experience in Latin America.
JCB has unveiled a mobile hydrogen refueler which it says will allow on-site refueling of hydrogen powered machines in the same way that fuel bowsers are used for diesel powered equipment.
The mobile hydrogen refueller is designed to provide an easy way to refuel machines, the vast majority of which have fuel delivered to them while working on site, said the company. JCB said customers are already used to a transportable fuel system.
The de-carbonization of the transport industry is heavily dependent on the scaling up of electric vehicle production rapidly and massively, and this rests on scaling up battery mineral mining and refining. This means Lithium.
Benchmark Mineral Intelligence counts 40 lithium mines that have been in operation and producing lithium in 2022. But, by 2050, the company sees a need for 234 more lithium mines if there’s no battery recycling underway (which, of course, is completely unrealistic but is a place to start from for such an analysis).
“The long term path for lithium is set, yet the supply chain scaling challenge has just begun,” said Simon Moores, chief executive of Benchmark. “What this data shows is that we are at just the beginning of a generational challenge, not one that’s going to be solved in the 2020s.”
A new EV battery recycling plant in Alabama from Li-Cycle has just come online. It can process up to 10,000 tons of battery waste per year, enough for about 20,000 EVs per year, and helps the US move toward a zero-emission economy.
Li-Cycle’s processing method is specifically designed as a two-part system recycling battery manufacturing scrap and turns end-of-life batteries into a black mass. The black mass is then processed and used to generate battery minerals such as nickel sulfate, lithium carbonate, and cobalt sulfate, three of the most critical factors for EV batteries. According to the battery recycling company, Li-Cycle believes its new method will enable up to a 95% efficiency rate compared to the industry average of 50%.
A new contract to supply battery electric vehicles to the Jansen potash project (potentially the world’s largest potash mine) expects to cut carbon emissions in half compared to its peers. BHP’s Jansen potash project is expected to be the largest of its kind, with initial capacity forecasts of 4.3 to 4.5 Mtpa. Potash is the most commonly used potassium fertilizer, but over 70% is based on conventional underground mining that uses heavy-duty equipment to extract it. Although underground mining releases half the CO2 emissions of open-pit mining, the company is reducing emissions further by introducing several battery electric vehicles.
Zio Holdings, a South Korean company engaged in the production and sale of electric motorcycles, says it has completed an electric motorcycle factory in Bac Ninh Province in northern Vietnam.
The factory covers an area of 1,300 m2 and has an annual production capacity of 12,000 units. The factory will receive parts supplied from original brand factories in Vietnam and China and will assemble the parts at ZIO EV’s factory in Vietnam.
The electric bikes to be manufactured at the new factory will be named “EDEN” and “MEVOYEZ,” and will use LFP batteries (lithium-ion iron phosphate batteries). The maximum speed is 55Km/h, and the driving range is over 150km. The selling price is expected to be 30 million VND (approximately 176,000 yen).
At 27%, the transport industry is the largest contributor to greenhouse gases in North America and Europe and within the transport sector, passenger cars contribute the most emissions followed by medium and heavy-duty trucks which contribute emissions at around 26% of the transportation industry. The move to reduce or eliminate emissions is one of the biggest priorities within the industry.
In a first, Ideanomics has announced that it successfully tested WAVE’s 500kW ultra-fast wireless charger at the Port of Los Angeles, which can charge class 8 electric trucks in less than 15 minutes. Installation of the wireless electric chargers is already underway at the Port of LA, and Ideanomics expects the first chargers to be ready for use in 2023
As companies seek to decarbonize their truck fleets, Ryze Hydrogen says that hydrogen combustion engines are the way to go– they are cleaner than diesel and they also make more economic sense, according to the company. Many companies today are looking at fuel cells in order to be able to use H2 as a clean fuel, but there is a growing movement toward the use of hydrogen combustion engines.
Cummins and Westpoint are cited as examples, with Cummins having unveiled a medium-duty concept truck using an H2-fueled internal combustion engine (ICE), which drew substantial attention in Germany at the IAA Transportation exhibition. Similarly, Westport Fuel Systems also unveiled its own HPDI hydrogen ICE engine for heavy duty vehicles earlier in September
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.
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.
