Environmental issues related to greenhouse gas emissions are progressively pushing the transition toward fossil-free energy scenario (carbon-neutral), in which renewable energies such as solar and wind power will unavoidably play a key role. However, for this transition to succeed, significant issues related to renewable energy storage have to be addressed. Power-to-X technologies have gained increased attention since they actually convert renewable electricity to chemicals and fuels that can be more easily stored and transported as energy-dense liquid hydrocarbons. Use of surplus renewable energy can reduce costs but requires that the process can be operated when energy is available and halted when the price goes up. In particular, the bioelectrocatalytic conversion of bio-derived metabolites such as medium-chain carboxylic acids, ethanol, butanol, etc. to energy-dense fuel and chemicals will be presented. |
