If upstanding citizens of early ‘90s UK culture The Shamen are to be correctly understood, their hit song was referring to e-methane, e-kerosene and e-methanol, otherwise known as e-fuels. These fuels, produced from renewable resources, like solar or wind, have come under closer scrutiny r...
What are renewable fuels? 𝕏 The main difference between renewable fuels and fossil fuels is where they come from. Fossil fuels, which are non-renewable, are made from fossil resources and release the carbon from these fuels into the atmosphere. Renewable fuels are made from previously used ...
Solar fuels are fuels made from common substances like water and carbon dioxide using the energy of sunlight. There is vast energy in sunlight striking the earth, but it is time-varying and dispersed, making it challenging to harness sunlight for practical use. We have successfully tapped solar ...
These fuels are typically blended with small amounts of conventional fossil fuels. Ethanol is a well-known conventional biofuel. First-generation ethanol is made from corn, while second-generation ethanol is produced from residues such as bagasse, a byproduct of sugarcane processing. Ethanol is ...

Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth’s crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels. Coal is a material usuall...
But it is seen as a death knell for the technology because of a dearth of options that could enable ICE cars to operate without producing CO2. Here's what you need to know. What are e-fuels? E-fuels, like e-kerosene, e-methane, or e-methanol, are made by synthesizing captured CO2...
