The ambitious scaling of electrolytic hydrogen production for net-zero targets is significantly constrained by the availability of land and freshwater resources, potentially limiting self-sufficiency for many nations. This resource management research insight is drawn from a 2023 study published in Nature Communications. Using Comparative analysis and scenario modelling, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must integrate detailed resource availability assessments (land and water) into the early stages of planning for any large-scale electrolytic hydrogen production projects.

Key Findings
- 01Less than 50% of projected global hydrogen demand in 2050 could be met through local production without facing land or water scarcity.
- 02Resource-rich regions like Southern and Central-East Africa, West Africa, South America, Canada, and Australia are identified as potential leaders in hydrogen export.
- 03Many countries will face constraints in achieving self-sufficiency in electrolytic hydrogen production due to domestic resource limitations.
Application
Design takeaway
Designers must integrate detailed resource availability assessments (land and water) into the early stages of planning for any large-scale electrolytic hydrogen production projects.
How to apply
When designing a hydrogen production facility, conduct a thorough assessment of local land suitability for renewable energy infrastructure and the availability of freshwater resources, considering potential competition from other sectors.
Project actions
- 01When proposing a design that relies on significant resource input (like water or land), research the local availability and potential conflicts for those resources.
- 02Consider alternative locations or technologies that might have a lower resource footprint.

Variables
Strengths & Limitations
Strengths
- +Provides a global perspective on resource constraints.
- +Quantifies potential limitations for hydrogen production.
Limitations
The availability of precise, up-to-date data on land and water resources can be challenging. The study also simplifies complex geopolitical and economic factors that influence resource allocation and international trade.
Reliability & validity
The study's validity relies on the accuracy of its projected demand and resource data. Reliability would be enhanced by using multiple modelling approaches and sensitivity analyses for resource availability.
Think critically
How might the competition for land and water resources between hydrogen production and other essential sectors (e.g., agriculture, urban development) impact the feasibility of large-scale hydrogen projects?
Design Principles
"Resource-aware design: Ensure that the design and scale of a project are aligned with the sustainable availability of critical natural resources."
Designers and engineers planning for large-scale renewable energy infrastructure, particularly for hydrogen production, must consider the finite nature of land and water. Ignoring these resource limitations can lead to project infeasibility, increased costs, and unintended environmental consequences, necessitating a more integrated approach to resource planning and allocation.
What This Means for Your Design
Making lots of hydrogen using wind and solar power needs a lot of land and water. This study shows that if we try to make all the hydrogen we'll need by 2050, many places won't have enough land or water to do it locally. Some countries with lots of land and water could become big hydrogen exporters.
How to use in your project

Paragraph starter
The global push for electrolytic hydrogen production, while crucial for decarbonization, faces significant constraints from land and water availability. Research indicates that meeting projected 2050 hydrogen demand through local renewable energy sources could be limited by these resources, suggesting a need for careful site selection, resource-efficient technologies, and international resource-sharing strategies.
