- Generation of liquidity
The Hydex increases transparency in the hydrogen market
The Hydex is a daily published cost-based spot price index for the three most important hydrogen technologies, developed and published by E-Bridge. It is based on the marginal cost of hydrogen production without capital costs, transportation and distribution costs in Germany. The most important variable input parameters are the short-term (daily) electricity and gas market prices as well as the future market price for CO2 emissions (EUA).
Since its first publication in March 2021 on E-Bridge.de and in the Energate Messenger, the Hydex has made the costs and competitiveness of especially green “renewable” hydrogen visible and updated. This makes it possible to estimate reliable hydrogen prices for different technologies and to obtain a calculation aid for investment decisions in the hydrogen market.
The Hydex Green describes the marginal production costs of the electrolyzer. The electricity procurement costs are determined based on the Day-Ahead market. In addition, green electricity certificates for all the required electricity (EU Wind GoO) are included. According to the regulatory framework, the Hydex Green does not take into account grid fees, EEG surcharges, and electricity tax.
The Hydex Blue describes the marginal production costs of the steam reformer. The gas procurement costs are determined based on the Day-Ahead market. The price includes the variable costs of CO2 capture, transport, and storage. Additionally, average grid fees for industrial customers’ natural gas procurement are assumed.
This text describes the Hydex Grey, which is a cost-based spot price index for grey hydrogen production. The gas procurement costs are based on the day-ahead market. The index includes the emission costs based on the current EU Emissions Trading System (ETS) certificate prices, and average network charges for the gas procurement by industrial customers.
Basis for your investment decisions – the HydexPLUS
The Hydex serves as an indicator and simple pricing instrument based on electricity, gas, and CO2 prices. However, for investment decisions, a full cost index is required, which takes into account the cost-optimal operation of the production (electrolysis or reforming). The HydexPLUS includes the investment costs for electrolysis or reforming and a full utilization hours calculation.
The HydexPLUS describes the lowest full costs of hydrogen production. Based on the commodity prices of the past year (t-365 days), the variable operating costs of green, blue, and gray hydrogen production are calculated in a daily resolution and sorted in ascending order. Capital costs and operating costs are then accumulated in 24-hour steps, with full load hours given in discrete 24-hour steps. Exactly one full cost value is assigned per step. As full load hours increase, the influence of capital costs on full costs decreases, and more days with higher variable operating costs or commodity costs are included. This parameter variation results in a cost-optimal operating point or full load hour number with the lowest full costs.
The following parameter assumptions are the basis for the calculation:
|Cost parameters||HydexPLUS Green||HydexPLUS Blue||HydexPLUS Grey|
|Unit||Electrolysis||Natural gas with CCS||Natural gas without CCS|
|Specific investment costs||EUR/kW||1000||1450||800|
|Operation and Maintenance (O&M)||% von Invest||2,20||3,00||4,70|
|Efficiency (based on lower heating value Hi)||%||65||70||75|
|Electricity or gas fees||EUR/MWh||16,95||9,94||9,94|
|Water costs||EUR / m³||4,00||–||–|
