To coal the process can also use other carbon sources such as biomass alcs. Others subsume one term under the other. Because of its clean renewable and ubiquitous nature solar energy can play an important role in the global renewable energy supply.

Energy changes in a reaction are calculated by bond energies and shown by energy diagrams. Several studies have investigated this electrochem. The system loses energy by both heating and doing work on the surroundings and its internal energy decreases.

There are two types of energy. Scientific challenges involved with this process include schemes to capture and convert solar energy and then store the energy in the form of chemical bonds producing oxygen from water and a reduced fuel such as hydrogen methane methanol or other hydrocarbon species.
