The technology involved in using H2 as an energy source can be costly for several reasons. Their use is considered to have zero-carbon operations but only when green H2 is used, meaning that it is produced using processes powered by renewable energy such as wind and solar. That said, the most common production method currently used involves burning natural gas, a fossil fuel.
Lithium-air batteries seemed destined for the dustbin of automotive history just a few years ago. But the US Department of Energy has tapped four different Li-air projects in a new round of funding aimed at developing new batteries powerful enough to move full-sized airplanes, locomotives, and seagoing vessels.
Regulations on EVs and developments in hydrogen power cells and battery technology are highlighted in articles in the March issue of Alternative Power Report produced by Power Systems Research. Read about Germany dropping subsidies for some electric trucks and buses and about the EU considering tariffs on Chinese EVs. PSR

CleanTechnica’s 2023 provisional report shows a 40% growth in demand for lithium-ion batteries in the automotive sector, reaching 712 GWh. CATL and BYD lead the market, with CATL holding a 34% share due to its successful partnerships and innovative battery technologies. BYD moved into second place with 16% share, up from 14% in 2022, replacing LG, which slid to third place with a 15% share. It had 17% in 2022. BYD grew 59% YoY.
CATL produced 243,000 units in 2023, up from 164,000 units in 2022. BYD produced 116,000 units in 2023, an increase from 73,000 in 2022.
LG lost share in 2023 due to the lack of new orders, GM’s troubled ramp-up of its new EVs, the end of life of some important volume models, and also the fact that volume from some clients, like Mercedes or Ford, is being diverted to the competition.
Caterpillar and CRH have collaborated to test electric mining trucks capable of hauling up to 100 tons, aiming for sustainable heavy equipment solutions and decarbonization. The electric 793 mining truck, capable of carrying 265 tons, features advancements such as autonomous hauling and regenerative braking, emphasizing its potential in safety, performance, and operational efficiency without immediate recharging needs. Electrek’s analysis underscores the significant reduction in carbon emissions and noise, highlighting the move towards a greener future in heavy machinery and mining industries.
As of Feb. 6, 2024, Shell permanently closed its seven light duty hydrogen fuel stations in California citing “hydrogen supply complications and other external market factors” for this decision. According to the below MOTORTREND article, this leaves 17 stations operational (although several are offline at the time of this writing) in the Bay Area, and just one in the Sacramento area.
Shell had already told industry outlet Hydrogen Insight that it would stop building any of the 48 new California stations it had planned—a significant number for the state—and that the company “made the decision to permanently close its light duty station network in California in early 2024.”
Cummins Brazil has announced the introduction of the new QSF 4.5 engine, boasting 210 horsepower at 2300 revolutions per minute (rpm), specifically tailored for the Off-Highway segment.
This 4-cylinder engine represents the pinnacle of power density in the Brazilian market. Start of production at the Guarulhos plant is scheduled to begin this April. The QSF 4.5 is a homegrown project designed by Brazilian engineers to cater to domestic market demands. It is derived from the F 4.5 engine used in the automotive sector by Cummins.
Volkswagen announced Feb. 4, 2024, that it plans to invest US$ 250 million in Argentina by 2026. Primarily, the funds will facilitate the ongoing production of the Amarok medium pickup truck, coinciding with the imminent launch of its new generation. Additionally, resources will be allocated towards sustaining the production of the Taos SUV.
At the same time, a new stamping line will be established in Pacheco. The investment also will enable the commencement of Ducati Motorcycle production at the Córdoba unit, which currently focuses on Volkswagen transmissions.
Toyota Motor Corporation and Chiyoda Corporation have announced the joint development of a hydrogen production system. The two companies plan to begin demonstration tests at Toyota’s main plant in fiscal 2025 and hope to begin marketing the system around fiscal 2027.
The system will produce hydrogen by electrolyzing water. It will have an output of about 5 megawatts and will be able to produce about 100 kilograms of hydrogen per hour. The new plant has a footprint of 6 meters wide by 2.5 meters deep, about half the size of a typical plant. By linking multiple plants, the production volume can be significantly increased.
