Several countries are emerging as future potential exporters of green hydrogen, while simultaneously pursuing ambitious energy transitions to reduce greenhouse gas emissions. | ||
Morocco serves as a blueprint for countries aiming to design their energy systems along these two dimensions, risking technology lock-in, unabated local energy-related greenhouse gas emissions, rising local energy prices, land use implications and neo-colonialism. | ||
Extending the current state of research, we conduct an integrated analysis of synergies and conflicts between these two objectives, taking into account the potential impact of hydrogen exports on economic benefits for both local populations and hydrogen exporters.

Results show that hydrogen exports could provide significant economic benefits for both hydrogen exporters and the local population, but also create potential conflicts and rising electricity and hydrogen prices. | ||

% Introduction/Background | ||
Several countries are emerging as future potential exporters of green hydrogen, while simultaneously pursuing their own ambitious energy transitions to reduce greenhouse gas emissions. | ||
The adoption of on-grid hydrogen electrolysis for export, reaching magnitudes multiple times of the domestic electricity demand, introduces the potential for profound impacts on both domestic electricity prices and energy balances. | ||
Vice versa, domestic mitigation and highly renewable electricity systems provide economic opportunities for hydrogen exporters. | ||
% Methods | ||
We explore the interactions between hydrogen exports, domestic mitigation and hydrogen regulation using a fully sector-coupled capacity expansion and dispatch model of Morocco across 14 regions, including integrated gas pipeline and electricity network planning based on PyPSA-Earth. The applied sector-coupled model simulates and optimises the Moroccan energy system in 484 scenarios at a 3-hourly temporal resolution, sweeping through different hydrogen export volumes, domestic mitigation levels and hydrogen regulations. | ||
% Results | ||
Our results show co-benefits of local mitigation and hydrogen export at medium mitigation (40 - 60\%) and moderate to high hydrogen exports (25 -- | ||
150 TWh). | ||
In addition, we reveal hydrogen regulation via temporal matching as decisive instrument to steer economic redistributions between hydrogen exporters and domestic electricity consumers. | ||
Hourly matching decreases the expenses for domestic electricity (up to -65\%) and increases expenses for hydrogen exports (up to 7\%) in high export and low mitigation scenarios. | ||
Our analysis across all three dimensions (export, mitigation, hydrogen regulation) shows the importance of strong hydrogen regulation in high export and low mitigation scenarios beyond the specific case of Morocco. | ||
The redistribution effects of hydrogen regulation are less pronounced in countries with a high share of renewable electricity. | ||
% Conclusion | ||
We reveal how hydrogen regulation can effectively hedge domestic electricity consumers against rising prices across mitigation and export scenarios. Integrated policies unlock synergies, potentially increase local acceptance by reducing domestic electricity prices and counteract neo-colonialism implications of hydrogen exports. | ||
