Enzymes can also process organic compounds such as sugars and alcohols, which are extremely frequent in nature. Most organic compounds cannot be used as fuel by fuel cells with metal catalysts because the carbon monoxide formed by the interaction of carbon molecules with oxygen during fuel cell deployment will quickly “poison” the metals valuables that the cell relies on, rendering it ineffective. . Because sugars and other biofuels can be developed and harvested on a large scale, fuel for enzymatic biofuel cells is cheap and can be found in almost every part of the world, thus making it a surprisingly amazing option from a logistical perspective, and even more so from a logistical point of view. so for those interested in adopting renewable energy sources. In recent years, hydrogenase research has grown significantly due to scientific and technological interest in hydrogen. The bidirectional or reversible reaction catalyzed by hydrogenase represents a solution to the challenge in developing technologies for the capture and storage of renewable energy as a fuel with on-demand use. This can be demonstrated through the chemical storage of electricity obtained from a renewable source (e.g. solar, wind, hydrothermal) such as H2 during periods of low energy demand. When energy is desired, H2 can be oxidized to produce electricity
