Energy storage is a key limiting factor in using green electricity and power from solar and wind resources as a highly efficient storage device should provide high power and deliver energy quickly, withstand a large number of charge-discharge cycles and be manufactured from environmentally friendly materials. Super-capacitors and redox flow batteries can meet most of the above criteria and, therefore, they can represent exciting alternatives to conventional batteries, but their efficiency is affected by the ability to transfer and store charged particles. This can be addressed by using environmental friendly electrodes with large surface area (e.g. porous electrodes) for ions to cling onto. The carbonaceous materials resulted from natural gas, methane or biomass processing can fulfil these conditions. The carbon black and bio-char obtained after natural gas/methane and biomass pyrolysis, respectively, contain high value carbon nanoforms. Their liquid suspensions can be used as inks for drop-on-demand ink-jet printing to create flexible electrodes for energy applications. Here, carbon nanoforms generation is reported and their inks properties are discussed in terms of stability and printability on different substrates.

Abstract
Energy storage is a key limiting factor in using green electricity and power from solar and wind resources as a highly efficient storage device should provide high power and deliver energy quickly, withstand a large number of charge-discharge cycles and be manufactured from environmentally friendly materials. Super-capacitors and redox flow batteries can meet most of the above criteria and, therefore, they can represent exciting alternatives to conventional batteries, but their efficiency is affected by the ability to transfer and store charged particles. This can be addressed by using environmental friendly electrodes with large surface area (e.g. porous electrodes) for ions to cling onto. The carbonaceous materials resulted from natural gas, methane or biomass processing can fulfil these conditions. The carbon black and bio-char obtained after natural gas/methane and biomass pyrolysis, respectively, contain high value carbon nanoforms. Their liquid suspensions can be used as inks for drop-on-demand ink-jet printing to create flexible electrodes for energy applications. Here, carbon nanoforms generation is reported and their inks properties are discussed in terms of stability and printability on different substrates.
