Comprehensive Report on Green Hydrogen Supply Chains

Introduction

Green hydrogen is emerging as a pivotal element in the transition toward a cleaner, decarbonized energy system, offering an alternative to traditional hydrocarbon-based fuels[1]. In contrast to fossil fuels that rely on carbon-based compounds, hydrogen serves as an energy carrier that can be produced with minimal carbon emissions when renewable energy is used as the driving force[1]. With significant advances in production technologies, researchers and industry leaders are exploring methods to produce, store, and transport hydrogen efficiently along emerging supply chains that aim to support future market demands[1].

Production Pathways and Cost Overview

Hydrogen production can occur via several pathways, including electrolysis of water and natural gas reforming methods. When produced from water through electrolysis powered by renewable energy, the hydrogen generated is classified as 'green hydrogen' and excludes fossil fuel contributions[1]. In contrast, natural gas reforming—which is economical—produces what is termed as 'grey hydrogen' or 'blue hydrogen' when carbon capture technologies are applied, but these processes entail significant energy inputs and subsequent CO2 emissions if not mitigated[1]. Current cost estimates for producing pure hydrogen range between $2.50 and $6.80 per kilogram, though advancements in technology and increased economies of scale are expected to drive production costs downward over the next decade[1]. These production strategies are being closely monitored as they form the foundation for the scaling up of a full hydrogen economy.
