Conclusion
Why would it work someday in agriculture? A lot of excess of electricity
Low prices for excess of electricity
Direct consumption of produced hydrogen
Eco‐farms in rural development and self‐
sufficient regions
• Renewable energy goals
•
•
•
•
Why doesn’t it work today in agriculture? • High investment and maintenance costs
• No hydrogen culture yet
