Technology life cycle and commercialization readiness of hydrogen production technology using patent analysis

Abstract

Hydrogen is a promising energy carrier with the potential to reduce greenhouse gas emissions and provide a stable energy supply; however, economic feasibility and supply stability limit its use. Hydrogen production technology (HPT) may be the key to overcoming these. Here, we explore HPT life cycle and strength characteristics to assess commercialization readiness using diverse analyses such as patents. Our findings show that HPT has matured and strengthened its competitiveness. However—despite the maturity—many challenges are required for commercialization success: the factor that might bridge this gap is securing price competitiveness. This study highlights the technological competitiveness of electrolysis has overtaken that of reforming and gasification. However, electrolysis has yet to achieve successful commercialization since it does not have appropriate price competitiveness. Therefore we argue for the immediate need to develop various technological methods—such as improved systems with cost-effective electrocatalysts—should be met for large-scale electrolysis commercialization. © 2022 Hydrogen Energy Publications LLC
