The General Index model is based on best-in-class Steam Methane Reforming (SMR) as the base technology with practical assumptions for the utilisation of the steam.
The base models track, measure and analyse industry-leading Proton Exchange Membrane (PEM) and Alkaline technologies to produce hydrogen production costs based on renewable energy prices in the relevant regions.
The General Index model utilises a modified version of the grey hydrogen methodology, coupled with distinct, best-in-class carbon capture technologies specific to each assessment region:
Amine-Based (Europe): Methyl Diethanolamine (MDEA) technology is modelled and serves as the primary enabler of carbon capture for the removal and sequestering of CO2 with >95% removal efficiency.
Users of our hydrogen price data can compare production costs globally in real time. The hydrogen assessments allow market participants to foresee which regions around the world will be able to produce hydrogen at lower cost than other geographies, setting up key precursors for determining potential future hydrogen trade flows.
General Index hydrogen price benchmarks reflect a true cost approach, incorporating:
Actual country-specific energy costs, updated daily
Capital cost tracking for the major hydrogen production technologies
Quarterly updates of capital costs, labour costs and other factors
Incorporates use of ammonia for NOx management for the selective catalytic reforming process in SMRs
Normalised pressure output assumed for each technology at 1500psig (~103 bar) to ensure a true ‘apples-to-apples’ comparison between technologies
Quarterly updated regional process water, demineralised water, nitrogen and ammonia prices which are applied to respective geographies and technologies
The data is published daily (subject to General Index holiday calendar) and made available to its subscribers via direct data feeds and emails to its customers. All prices are published in £/kg.
