Electricity cheaper than diesel for heavy goods vehicles

Electricity cheaper than diesel for heavy goods vehicles

EconomicsEnergy

Electrifying long-haul cargo-carrying trucks was deemed financially unviable. However, recent findings from researchers at Chalmers University of Technology demonstrate that operating electric heavy goods vehicles can be more cost-effective than using diesel. The shift from fossil fuel-powered to electric vehicle fleets has primarily been noticeable in lighter vehicles like private cars and delivery vans. However […]

Renewable energy sources are crucial to react to the continuous increase of energy consumption and pollution by carbon dioxide emissions worldwide. Biofuels, where the energy content is derived from a biological source, are one of the alternatives to oil and natural gas. Still, some biofuels are controversial, like biodiesel, because they imply cultivating certain crops […]

Tides are more predictable than winds or sunshine. Then, why are not they already widely used as a source of renewable energy? The simple answer is that designing and building an ocean energy array is quite complex. This complexity has an associated variability in the cost of energy that makes projects difficult to evaluate from […]

From electric vehicles to storing wind and solar energy produced during off-peak hours, rechargeable lithium-ion (Li-ion) batteries are the best option that we currently have tu support our technological future. But if we want them to be truly environmentally-friendly and safe devices, they do need some changes. The Li-ion battery is a rechargeable cell. Typically […]

Nature is a source of inspiration for scientists. If the efficiency of natural processes efficiency has been honed by billions of years of evolution, it seems reasonable that the best way to achieve some process is to try and mimic what nature has already come up with. This is the case with photosynthesis, a process […]

A tax on carbon emissions is an efficient way to make firms and consumers internalize the environmental costs due to climate change. However, there are many other aspects to consider in a transition from a fossil-fueled economy to a cleaner one. In a past article we presented the case for subsidies on research to develop […]

Both the depletion of fossil fuels and the environmental concerns are a powerful drive for the development of sustainable routes to commodity chemicals. Lignocellulose, comprised of lignin, cellulose and hemicellulose, is the ideal candidate, but its inherent complexity hampers its transformation to value-added chemicals. The group of Katalin Barta at the University of Groningen has […]
