Hydrogen is gaining attention as a clean energy carrier, but many people still have questions about its safety, production and practical uses. Below we answer the top 10 queries we receive from clients and the public.
1. Is hydrogen safe?
Yes, when handled with proper safety measures. Hydrogen is non‑toxic and non‑corrosive. Modern systems incorporate leak detection, ventilation and automatic shutdown. At INFENER we exceed ISO 22734 safety standards for all our installations.
2. How is green hydrogen produced?
It is generated by electrolyzing water using electricity from renewable sources such as wind, solar or hydro. The process emits no CO2, unlike grey hydrogen produced from natural gas.
3. What is the efficiency of electrolysis?
Current commercial electrolyzers achieve 65‑75 % efficiency. Ongoing research aims to push efficiencies above 80 %.
4. Can hydrogen be stored long‑term?
Hydrogen can be stored in compressed gas cylinders, liquefied tanks, or underground caverns for months and even years without significant loss.
5. What are the main applications?
Key sectors include:
- Industrial heat and processes.
- Fuel‑cell vehicles and buses.
- Power‑to‑gas for grid balancing.
- Ammonia and synthetic fuel production.
6. How does hydrogen compare to batteries?
Batteries excel at short‑term, high‑power delivery, while hydrogen offers high energy density for longer duration storage. The technologies are complementary rather than competing.
7. What infrastructure is needed?
At minimum you need an electrolyser, storage tanks, safety systems and a connection to the end‑use (e.g., fuel‑cell stack or combustion burner). INFENER provides turnkey, plug‑and‑play modules that simplify deployment.
8. Are there incentives available?
Many countries offer subsidies, tax credits, or carbon‑price exemptions for green hydrogen projects. Consult local authorities or our financing team for details.
9. What is the environmental impact?
Green hydrogen has a negligible carbon footprint when powered by clean electricity, making it a key tool for decarbonization across sectors.
10. How can I start a hydrogen project?
Contact INFENER for a feasibility study. We guide you from concept through design, financing, installation and operation.
