Solar fuels, in particular hydrogen, are viewed as an alternative source of energy for replacing fossil fuels especially where storage is essential. Electricity can be produced directly from sunlight through photovoltaics , but this form of energy is rather inefficient to store compared to hydrogen. [ 7 ]
Artificial photosynthesis is a chemical process that biomimics the natural process of photosynthesis.The term artificial photosynthesis is used loosely, referring to any scheme for capturing and then storing energy from sunlight by producing a fuel, specifically a solar fuel. [1]
Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
Once they're made, experts say, biofuels have advantages over pure fossil fuels by contributing little to no emissions at the tailpipe. The same can't be said of the gasoline and diesel they are ...
Biofuels are biomass-derived fuels from plants, animals, or waste; depending on which type of biomass is used, they could lower CO 2 emissions by 20–98% compared to conventional jet fuel. [67] The first test flight using blended biofuel was in 2008, and in 2011, blended fuels with 50% biofuels were allowed on commercial flights.
Electrofuels, also known as e-fuels or synthetic fuels, are a type of drop-in replacement fuel. They are manufactured using captured carbon dioxide or carbon monoxide, together with hydrogen obtained from sustainable electricity sources such as wind, solar and nuclear power.

Biological photovoltaic devices are a type of biological electrochemical system, or microbial fuel cell, and are sometimes also called photo-microbial fuel cells or “living solar cells”. [3] In a biological photovoltaic system , electrons generated by photolysis of water are transferred to an anode . [ 4 ]
