Tests Conducted In Brazil, United States, And Austria Confirm The Advancement Of Technology That Will Allow The Replacement Of Diesel With Ethanol In Vale Locomotives, Scheduled To Begin In 2028

A new technology is in the testing phase in Brazil and promises to transform the rail sector: the ethanol-powered train. The goal is to replace diesel with a cleaner and more sustainable fuel, reducing pollutant gas emissions.

The tests are underway and, starting in 2028, the change is expected to become a reality in trains operated by Vale, which transport ore from Minas Gerais to Espírito Santo, as well as passenger trains.

The technology is considered unprecedented in the railway world. The initial testing phase is taking place in laboratories in the United States, Austria, and Brazil.

Adaptations And Advantages Of The Technology

To enable the use of ethanol, locomotives will undergo adaptations and will operate with flex engines, also known as dual-field, that accept alternative fuels.

According to Daniela Ornelas, Vice President of Product at Wabtec, the modifications include adjustments to the injection system and possible changes to the fuel tank, which is currently designed for diesel.

In addition to reducing pollutant emissions, the new system maintains train performance.

João Turchetti, Director of Decarbonization Engineering at Vale, explains that the choice of ethanol follows a clear logic: as the biofuel is already widely used in gasoline, its expansion to railway diesel is a natural step.

Brazil has ample availability of ethanol in the Central-West and Southeast regions, facilitating initial implementation and paving the way for future expansions.

Etanol com baterias elétricas recarregável já que temos ônibus elétrico de viagem hibrido para para viagem de longo curso e elétrico para o urbano, novas baterias q poderia ser do tamanho de um vagão, recarregável e movido a etanol…é o mundo se modernizando….

Adaptations And Advantages Of The Technology

In the cold desert of Ladakh, where it hardly rains, engineer Sonam Wangchuk created the ice stupa, a tower that freezes winter water and stores it for irrigating crops in the spring, a simple engineering feat that mimics nature.

Almost 6,000 residents live concentrated along a single street nearly 9 km long in the interior of Poland. Houses form a continuous row, and behind them, narrow agricultural strips emerge, creating one of the most unusual rural patterns in Europe.

Júlia Pimentel, an 11-year-old from Minas Gerais, independently invented a new formula to calculate the square root using simple addition and multiplication, and her method was published in one of the most important mathematical scientific journals in Brazil.

They planted a sea of eucalyptus to produce cellulose, but the monoculture turned into a green desert, dried up springs and rivers, and pushed families out of regions in Minas Gerais and Bahia.

Chinese woman planted trees for decades while sand buried part of her house, received $5,000 from an American in 1999, and helped transform the desert into a forest of 8 million trees in China.

Heir bought 23,000 degraded acres in the Scottish Highlands, fenced the area, planted nearly 1 million native trees, and transformed empty mountains into a forest officially recognized after meeting 15 evaluation criteria over 20 years.

The Atacama Desert, the driest place on Earth, was covered in flowers and turned into a colorful carpet with more than 200 species in the phenomenon called “desert bloom,” when atypical rains awaken seeds that had remained dormant in the soil for many years.
