The research presents a novel long-term planner that determines the optimal hydrogen production for the next day by considering both short-term forecasts and recent historical data on solar and wind capacity factors, electricity prices, and CO2 intensity. This approach aims to overcome the limitations of relying solely on long-term forecasts, which are often unreliable.
The key highlights and insights are:
Longer delivery periods (e.g., weekly, monthly, yearly) provide more flexibility to co-optimize cost and CO2 emissions, enabling significant reductions in emissions with relatively small increases in the levelized cost of hydrogen.
Under day-to-day operation, the levelized cost of hydrogen is marginally higher than the benchmark performance with full foresight, but the CO2 emissions can be up to 60% higher.
Despite a significant portion of the produced hydrogen not meeting the current criteria for green hydrogen designation, the CO2 emissions are still lower than those from existing alternative hydrogen production methods.
The analysis of the current regulations for green hydrogen production reveals a lack of transparency, and recommendations are made to improve the regulations, such as adopting transparent accounting based on hourly CO2 emissions and reducing the specific CO2 emission threshold for green hydrogen production.
