The use of hydrogen as an energy carrier for farms and greenhouses represents a strategic frontier in the energy transition of the agri-food sector. In a context where the decarbonisation of agricultural activities is an environmental and regulatory priority, the production of green hydrogen through electrolysis powered by renewable energy plays a central role in reducing the use of fossil fuels, increasing energy self-sufficiency and supporting the operational continuity of agricultural businesses.
How hydrogen makes farms and greenhouses sustainable
Traditional agriculture is one of the sectors most dependent on fossil fuels for machinery, irrigation systems, greenhouse heating and other operational processes. The integration of hydrogen systems makes it possible to:
- reduce environmental impact by eliminating CO₂ emissions and other pollutants associated with diesel and traditional fuels
- increase energy efficiency through the use of fuel cells and hydrogen engines, which produce only water vapour as a by-product.
These technologies have already been tested in agriculture: for example, some manufacturers have developed prototypes of hydrogen-powered tractors that can operate like conventional tractors but with virtually zero emissions, demonstrating the feasibility of practical applications in agricultural vehicles.
Producing green hydrogen with solar and wind power
Green hydrogen is produced through water electrolysis, a process that breaks down water into hydrogen and oxygen using electricity from exclusively renewable sources such as photovoltaic or wind power. This allows clean energy to be generated directly on the farm, reducing dependence on the electricity grid and fossil fuels.
Agricultural facilities equipped with photovoltaic systems and wind turbines can therefore power integrated electrolysers, creating a completely renewable and sustainable energy supply chain. The combination of renewable production and green hydrogen follows the potential outlined in European strategies to increase the installed capacity of electrolysers to tens of gigawatts by 2030.
Given that farms experience long periods of low consumption interspersed with short periods of high electricity consumption, it is possible to store energy from renewable sources over the course of several months in the form of hydrogen, and then use this reserve during peak periods. This type of energy storage cannot be achieved with batteries, which have much shorter charge and discharge cycles. Furthermore, as these types of businesses have large spaces available in isolated locations, they are not required to comply with specific safety distances from other structures and can therefore store large quantities of hydrogen on site.
Hydrogen storage and energy management for business continuit
One of the main challenges in using renewable energy is the variability of production linked to climatic conditions. Hydrogen plants address this critical issue thanks to their ability to store energy in the form of hydrogen, which can be used at times of need or when solar/wind energy production is low.
This approach allows farms to achieve:
- business continuity, with energy reserves during peaks in demand or in the absence of wind or sun.
- integration with smart energy management systems, which optimise production, storage and consumption to maximise overall efficiency.
The ability to store excess hydrogen produced is a strategic element in ensuring energy stability for greenhouses, avoiding interruptions in heating, ventilation or agricultural production processes, particularly for long-term storage that is not possible with other energy storage methods (e.g. batteries).
Practical applications in the field: traction, electricity, heat and auxiliary processes
There are many operational applications for hydrogen systems in agriculture:
- traction of agricultural vehicles: tractors and operating machines can be powered by hydrogen fuel cells, with benefits in terms of reduced emissions and quiet operation
- energy and heat generation for greenhouses: a cogeneration system with hydrogen fuel cells to produce electricity and heat can improve energy efficiency and support greenhouse heating in harsh climatic conditions, improving crop yield and quality
- Support for auxiliary processes: irrigation systems, controlled ventilation, post-harvest drying and other activities can be powered by hydrogen as an energy source, reducing the use of fossil fuels and improving the overall energy efficiency of the farm.
When integrated consistently with on-site renewable systems, these applications contribute to sustainable and innovative agriculture, in line with current climate objectives and environmental regulations.
