Small factories, big impact: how ZEF is reshaping the energy transition
Zero Emission Fuels (ZEF), a spin-off from TU Delft, is developing groundbreaking micro-plants that convert solar energy directly into methanol—a sustainable and versatile fuel. These compact systems are connected to solar panels and efficiently convert locally generated energy without relying on the electricity grid. The key to this innovation lies in the direct conversion of solar power into hydrogen via an integrated alkaline electrolyzer.
A new standard in decentralized energy production
While many Dutch hydrogen projects focus on large-scale electrolyzers, ZEF is taking a different path. Their micro-plants feature a small-scale, modular electrolyzer that can be directly connected to solar panels. Thanks to a smart design, this electrolyzer can follow the fluctuating power output of solar panels without the need for expensive power electronics. This makes the system not only cheaper but also easier to install in standard solar parks.
This approach opens the door to applications in remote areas, developing regions, and small-scale installations where grid connections are lacking. By producing methanol and hydrogen locally, sustainable energy becomes more accessible than ever.
From prototype to production llne
As part of the NXTGEN Hightech project, ZEF is working on further developing the technology. An automated assembly line is being set up to enable large-scale production of the micro-plants. This scalable approach ensures lower costs, consistent quality, and rapid deployment. In collaboration with customers, the systems are tested in field labs and pilots, without requiring major investments.
The modular design allows for flexible adaptation to local energy needs. This not only offers economies of scale but also significantly reduces installation and commissioning costs.
A breeding ground for talent and innovation
ZEF invests not only in technology but also in people. More than 400 students from various disciplines have already gained hands-on experience within the company. They learn about electrolysis, system design, and sustainable energy, and actively contribute to the development of the hydrogen ecosystem. This collaboration with educational institutions ensures a continuous influx of new knowledge and strengthens the sector’s innovative capacity.
Applications with global reach
ZEF’s technology is particularly well-suited for sunny regions, remote locations, and small-scale applications. By directly connecting to renewable energy sources, methanol and hydrogen can be produced locally without the need for a grid connection. This makes the system attractive for a wide range of sectors, from agriculture and transport to energy supply in developing countries.
