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.

Studies indicate that, initially, it will be possible to replace up to 50% of diesel with ethanol, with the goal of eventually achieving a 100% biofuel-powered engine.

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.

Adaptations And Advantages Of The Technology

At just 14 years old, a boy creates a system without energy, using steel pipes buried in the ground, that irrigates seedlings with moisture from the air, to combat the water scarcity threatening reforestation in northern China.

Where there was only sand and wind at 40 degrees, China built a megacity of 500,000 inhabitants with farms, wineries, and universities in the middle of the desert using melted glacier water from hundreds of kilometers away.

At over 8,800 meters above sea level, the summit of Mount Everest is made up of rocks that originated at the bottom of an ocean about 500 million years ago and were pushed to the highest point on Earth by the collision of tectonic plates.

“No one will make us change the Pix,” says Lula after the US report.

In just three hours, a natural stone floor transforms the entrance of the house with an organic effect, immediate drainage, and a sophisticated non-slip finish that doesn’t puddle water, dries quickly, and impresses with the final result.

New technology with lights is being tested in the most dangerous stretch of Serra do Mar in Paraná to alert drivers, reduce delayed reactions, and try to curb the rise in deaths on the highway.

Alert in the global energy market: Severe tropical cyclone hits the coast and disrupts gas production at major plants in Australia, threatening global supply.

“No one will make us change the Pix,” says Lula after the US report.

He started running at 66 years old, broke records at 82, and is now a subject of study for having a metabolic age comparable to that of a 20-year-old, in a case that is intriguing scientists and inspiring the world.

Less than a Tera TSI, up to 710 km of range and charging in 9 minutes: the new BYD Song Ultra expands the Chinese brand’s bet on increasingly faster, more technological, and competitively priced electric SUVs.

With a cost per shot close to zero, the DragonFire laser could change naval warfare in 2027 and provide British ships with nearly unlimited defense against drones.

A British startup creates tires that generate electricity in electric vehicles when passing over potholes, speed bumps, and cracks.
