São Paulo Adopts Biomethane in Bus Fleet
On Sept. 2, 2025, the biggest city in Americas with biggest bus fleet, started on the path to use of biomethane as fuel in the city’s public transport fleet and garbage collection vehicles. The initiative sets rules for fuel acquisition and introduces the gradual adoption of biomethane-powered vehicles. City officials emphasize that biomethane offers lower operating and acquisition costs compared to electric buses and avoids the need for large-scale charging infrastructure.

Sharing of EV Battery Data Supported by METI

Akihiro Komuro The Ministry of Economy, Trade and Industry says it will support the development of an industry-wide system for sharing information on the degradation status of EV batteries. Toyota and Honda will provide battery-related data to used car dealers, insurance companies and others. The aim is to prevent the export of used EVs overseas and enable the domestic utilization of batteries containing critical minerals.
Currently, battery degradation is difficult to assess, resulting in low trade-in prices for used EVs in the domestic market. The fact that approximately 80% were exported overseas was a cause for concern.

Proton Builds First EV Plant in Malaysia
Proton, Malaysia’s national car brand, opened its first EV factory in the state of Perak. The factory has an annual production capacity of 20,000 units, which can be expanded to 45,000.
Construction of the factory costs a total of 82 million ringgit (approximately $19.47M). Proton receives technical support from its major shareholder, Zhejiang Geely Holding Group of China. Previously, Proton imported EVs produced at Geely’s factory in Hangzhou, Zhejiang Province, China.

Vietnam Shifts To EV Motorcycles

Akihiro Komuro Vietnam, a country known for its large number of motorcycles, is experiencing controversy over its electric vehicle policy. The policy bans gasoline-powered motorcycles in certain areas of Hanoi, the capital, and has caused a stir. Honda, which holds an 80% share of the local motorcycle market, must rethink its strategy because most of its models run on gasoline. This sudden policy change could also disrupt daily life for residents.
In July, the Vietnamese government outlined bold measures to regulate gasoline-powered motorcycles in “Prime Ministerial Directive No. 20.” Starting in July 2026, operating gasoline-powered motorcycles within the Inner Ring Road in Hanoi will be banned. The Inner Ring Road spans over seven kilometers and includes the city center, home to government offices, the Japanese embassy, and the historic Old Quarter, a popular tourist destination.

Goiânia at Forefront of BEV Bus Transportation
Goiânia (GO) will become the first city in the world to operate a regular fleet of 100%-electric bi-articulated buses, as a result of a partnership between Volvo and GreenMob Capital. The fleet includes 21 Volvo BZRT buses—16 articulated (with a capacity of approximately 180 passengers) and 5 bi-articulated (with a capacity of about 250 passengers). These zero-emission, ultra-quiet vehicles are slated to serve the BRT Leste‑Oeste corridor within the RMTC system, with initial operations scheduled to begin by late August 2025.

GWM Tests Hydrogen Truck in Brazil
GWM has brought its Hydrogen powered by FTXT truck prototype to Brazil for tests at its Iracemápolis (SP) plant, coinciding with the factory’s inauguration Aug. 15, 2025. The vehicle combines a 105 kWh battery with 40 kg of hydrogen in onboard tanks feeding a fuel cell, producing only water vapor. Tests will begin in September, assessing safety, performance, consumption, and adaptation to Brazilian roads, first unloaded and later with simulated cargo.

BP Drops Hydrogen Plan in Australia

Guy Youngs BP first bought a 40.5% operating stake in the Australian Renewable Energy Hub project in 2022, and its share in the joint venture grew to 63.57% in recent years. The project would include the installation of up to 26 GW of solar and wind generation, much of which would have been used to produce green hydrogen and ammonia.
British energy major BP has informed its partners that it intends to exit the $55 billion (USD 36.14 billion) green energy hub planned for Western Australia’s Pilbara…

Restructured Water Boosts Electrolysis Efficiency
In a paper published in August 2025 in JACS Au (American Chemical Society), Chinese researchers showed that by steering the hydrogen-bond network of interfacial water via a steady magnetic field, they sliced off about 50 millivolts of overpotential for the hydrogen evolution reaction and cranked current density up by 15.4% under industrial alkaline electrolysis conditions.
Water molecules near the electrode reshuffle into more asymmetrical clusters. These lopsided water gangs hand off protons and…

Tesla Sales in Europe Are in Free-fall
Tesla sales in Europe are continuing to decline rapidly, and it appears the pain is just beginning for the automaker. The numbers for July are coming in from Europe and Tesla registrations are down 41.6% despite EV sales surging across the continent.
The data shows that the free-fall decline in sales that we saw in the first half of 2025 is continuing into the second half, despite Tesla falsely claiming that the issue in the first quarter was the Model Y changeover limiting supply.
