Why hydrogen?
Hydrogen is the simplest and lightest element. It is found in water (H₂O) and many other molecules.
Scientists and engineers are excited about hydrogen because it can store and deliver energy without producing carbon dioxide when used in a fuel cell. This makes hydrogen an important part of future energy ideas like “clean cars” and “green power.”
These hydrogen project ideas help students learn important science topics: electricity, chemistry, energy conversions, environmental impact, and engineering design.
Some projects are hands-on experiments (like making hydrogen gas through electrolysis), while others are research, design, or build projects (like making a small fuel-cell car or a poster about the hydrogen economy).
Always follow safety rules and ask an adult to help with anything electrical, hot, or pressurized.
How to use these hydrogen project ideas
- Read through the project ideas and pick one that matches your age, available tools, and safety rules.
- Gather materials. Many projects use safe, common items. Some require small kits or classroom equipment—ask your teacher or parent if you need help buying them.
- Follow safety notes closely. Wear safety glasses and gloves when needed, and work with adult supervision for experiments that involve electricity or gas collection.
- Record observations, take photos or video (if allowed), and write a clear conclusion that explains what you learned.
- Try one extension idea to deepen your learning.
15 Hydrogen Project Ideas 2026-27
Below are 15 student-friendly hydrogen project ideas. Each project includes: objective, materials, step-by-step procedure, expected results and science explanation, safety notes, and extension suggestions.
Project 1 — Simple Water Electrolysis: Make Hydrogen and Oxygen
Objective: Show how electricity splits water into hydrogen and oxygen (electrolysis).
Materials:
- Small DC power source (a 6–9 V battery or a low-voltage DC power supply)
- Two graphite electrodes (pencil leads or carbon rods) or stainless steel spoons (avoid copper)
- A plastic cup or small beaker
- Distilled water and a pinch of table salt or baking soda (to help conductivity)
- Two small test tubes or balloons (to collect gas)
- Wires with crocodile clips
- Safety glasses, gloves
Procedure:
- Fill the cup with distilled water and add a pinch of salt or baking soda, stirring until dissolved.
- Place the two electrodes a short distance apart in the water.
- Invert two small test tubes filled with water over the electrodes (or attach balloons to the electrodes to collect gas).
- Connect the electrodes to the battery using wires (one electrode to the positive, the other to the negative terminal).
- After some minutes, you will see bubbles form at both electrodes. The negative electrode (cathode) produces hydrogen gas; the positive electrode (anode) produces oxygen gas.
- Measure the amount of gas collected in each test tube or balloon over a set time.
Expected results & explanation:
Water (H₂O) splits into hydrogen (H₂) and oxygen (O₂) when electricity flows. The volume of hydrogen produced will be about twice the volume of oxygen (because two hydrogen atoms combine for every oxygen atom in water). This demonstrates the chemical equation:
2 H₂O(l) → 2 H₂(g) + O₂(g) (with electricity)
Safety notes:
Do not use high voltages. Work with adult supervision. Do not ignite collected gases — if you use a splint test for oxygen or hydrogen, do this only under strict adult supervision in a proper lab.
Extensions:
- Change the power supply voltage and compare gas production rates.
- Test different electrode materials (graphite vs stainless steel).
- Use a small solar panel as the power source (see Project 2).
Project 2 — Solar-Powered Electrolysis (Green Hydrogen Demo)
Objective: Use a small solar panel to split water and produce hydrogen — a model of “green hydrogen.”
Materials:
- Small solar panel (1–5 W) with wires
- Electrolysis setup from Project 1 (cup, electrodes, test tubes or balloons)
- Distilled water + a pinch of baking soda
- Multimeter (optional, to measure voltage/current)
- Safety equipment
Procedure:
- Set up the electrolysis apparatus as in Project 1.
- Connect the solar panel wires to the electrodes (positive to anode, negative to cathode).
- Place the solar panel in bright sunlight or under a strong lamp.
- Observe bubble formation and gas collection. Measure how sunlight intensity affects gas production.
Expected results & explanation:
When sunlight powers the solar panel, it supplies electricity to split water into hydrogen and oxygen — a simple demonstration of producing hydrogen using renewable energy.
Safety notes:
Avoid direct contact with panel terminals and follow the safety guidance in Project 1.
Extensions:
- Measure how different light intensities change hydrogen production.
- Calculate energy input (solar power) vs the volume of hydrogen produced to estimate efficiency.
Project 3 — Compare Electrolytes: Salt vs Baking Soda vs Distilled Water
Objective: Discover how different dissolved substances (electrolytes) change the speed of electrolysis.
Materials:
- Electrolysis apparatus (from Project 1)
- Distilled water
- Table salt, baking soda, and a small amount of vinegar (three test samples)
- Measuring spoons and cups
Procedure:
- Prepare three separate cups, each with distilled water. Add the same small amount of salt to one cup, baking soda to the second, and vinegar to the third.
- Perform electrolysis for the same amount of time in each cup using the same electrode spacing and voltage.
- Collect and measure the volume of gas produced in each trial.
Expected results & explanation:
Solutions with better conductivity (electrolytes that dissociate into ions) will increase the rate of electrolysis and produce more gas. Salt and baking soda increase conductivity more than pure distilled water. Vinegar (acetic acid) also changes conductivity but may react differently with some electrode materials.
Safety notes:
Use safe concentrations and adult supervision. Avoid mixing chemicals outside the test cups.
Extensions:
- Graph gas volume vs type of electrolyte.
- Explain why ions are important for current flow in water.
Project 4 — Electrode Material Test: Which Makes Hydrogen Fastest?
Objective: Compare how electrode material affects hydrogen production.
Materials:
- Electrolysis setup
- Several electrode materials: graphite (pencil lead), stainless steel, copper, and aluminum (small pieces)
- Distilled water + baking soda
- Timer, measuring cylinder
Procedure:
- Set up electrolysis using one electrode material at a time (keep the other electrode the same for control).
- Run each trial for the same time and measure the gas produced.
- Compare results and record observations like corrosion or color changes.
Expected results & explanation:
Some materials work better and last longer (graphite and stainless steel are safer). Copper and aluminum can corrode or dissolve and may contaminate the water. The activity depends on conductivity, electrochemical reactions, and stability.
Safety notes:
Avoid heavy corrosion products. Dispose of used solutions responsibly.
Extensions:
- Study electrode wear under different voltages.
- Explain real-world reasons why certain electrode materials are chosen in industry.
Project 5 — Build a Small Fuel Cell to Light an LED
Objective: Use a commercial small fuel-cell kit to convert hydrogen energy back into electricity.
Materials:
- Small PEM fuel cell educational kit (available online or from science suppliers)
- A small source of hydrogen (some kits come with a cartridge or you can use hydrogen produced through safe electrolysis and carefully stored; follow kit instructions)
- LED or small motor
- Wires, switch
- Safety gear and adult supervision
Procedure:
- Read the fuel cell kit instructions carefully.
- Connect the fuel cell to the LED and switch.
- Supply hydrogen to the fuel cell as explained by the kit. The fuel cell will combine hydrogen and oxygen (from air) to produce electricity and water.
- Observe the LED lighting or the motor running.
Expected results & explanation:
A fuel cell works like a reverse of electrolysis: hydrogen and oxygen react electrochemically to produce electricity, with water as a byproduct. This demonstrates that hydrogen can be an energy carrier.
Safety notes:
Follow kit manufacturer instructions. Use hydrogen sources recommended by the kit and do not attempt to pressurize gases without proper equipment.
Extensions:
- Measure the current and voltage produced under different loads.
- Compare the fuel cell output to a small battery.
Project 6 — Hydrogen-Powered Model Car (Fuel Cell Kit)
Objective: Build a small model car powered by a fuel cell.
Materials:
- Fuel cell car kit (these contain a small fuel cell, motor, chassis; available as science kits)
- Small hydrogen cartridge or safe hydrogen source following kit instructions
- Tools included in kit
Procedure:
- Assemble the car according to the kit manual.
- Attach the fuel cell and hydrogen source as instructed.
- Place the car on a flat surface and run it. Time how far it travels or how long it runs.
Expected results & explanation:
The fuel cell converts hydrogen into electricity to run the motor. This project gives a real-world feel for hydrogen-powered vehicles and shows the differences between batteries and fuel cells.
Safety notes:
Use kit-approved hydrogen sources and adult supervision. Keep away from flames or sparks.
Extensions:
- Modify the car to improve speed or range (gear changes, lighter parts).
- Compare energy per gram of hydrogen vs battery energy density.
Project 7 — Compare Hydrogen vs Helium vs Air Balloons (Lift Study)
Objective: Compare how different gases affect lift and explain why hydrogen gives more lift than air or helium.
Materials:
- Three identical small balloons
- Helium from a party tank (adult to help)
- Air (blow with lungs or pump)
- (Optional) If a safe source of hydrogen is available and permitted by an adult, a very small hydrogen sample; otherwise use calculations and safe demonstration
- Scale (optional) to weigh balloons
Procedure:
- Fill one balloon with air, one with helium, and (if safely available) one with hydrogen.
- Observe lift and timing of float. Which balloon rises the most?
- If hydrogen is not used directly for safety reasons, calculate the expected lift using the density of gases and show that hydrogen has the highest lift due to lowest density.
Expected results & explanation:
Hydrogen is the lightest gas, so it gives the most lift. Helium is the next lightest and is used in balloons because helium is non-flammable. This project teaches gas density and safety trade-offs — hydrogen lifts more but is flammable.
Safety notes:
Do not release hydrogen in public spaces and avoid experiments that create or release hydrogen without expert supervision. When demonstrating hydrogen’s lift capacity, using calculations or simulations is safer than releasing hydrogen.
Extensions:
- Create a poster comparing safety, cost, and availability of hydrogen vs helium.
- Show the math behind lift using densities and Archimedes’ principle.

Objective: Quantify how changes in voltage or current change the rate of hydrogen production.
Materials:
- Electrolysis setup
- Variable DC power supply or multiple batteries to vary voltage
- Ammeter and voltmeter (multimeter)
- Measuring cylinder or gas syringe to measure gas volume
Procedure:
- Set a fixed electrode spacing and use the same electrolyte solution.
- Run electrolysis at several different voltages, measuring the current each time.
- Collect the gas produced for a fixed time (e.g., 5 minutes) and measure volume.
- Plot gas volume vs voltage and vs current.
Expected results & explanation:
Higher voltage/current speeds up electrolysis (more electrons flow, more water molecules split). This experiment introduces the quantitative relationship between electricity and chemical reactions.
Safety notes:
Higher currents can heat components — watch for heating and avoid touching hot electrodes. Use adult supervision.
Extensions:
- Calculate the theoretical amount of gas using Faraday’s laws of electrolysis and compare with your results.
- Discuss energy efficiency: energy in vs chemical energy stored in hydrogen.
