14.Natural Gas Desulphurisation, Hydrogen From Gas, Energy Storage And Hydrogen Storage
Activated Carbon continues to promote the greening of energy technologies from the guardian of desulphurisation (natural gas purification), hydrogen production (coal gasification - CCS), to the pioneer of energy storage (supercapacitor) and hydrogen storage carrier (low temperature adsorption). Future trends will focus on biomass resource utilisation (ramie/lancashire substitution) and precise pore structure control (pore size-surface chemistry synergy), in order to realise highly efficient energy conversion under the goal of ‘dual-carbon’.
