Other hydrogen generators may have been produced with other uses in mind, such as to supply hydrogen as a reactive gas for synthetic chemistry, in which case, a higher pressure supply of gas is often preferred, and users are not often overly worried about losing a decimal point of purity to achieve that.
Some more sophisticated hydrogen generators such as the ThalesNano Energy H-Genie have built in mass flow controllers, meaning that the flow from the generator can be accurately measured, controlled and logged. Logging the changes in hydrogen production during a reaction in which the generator is asked to maintain a constant gas pressure means that kinetics data can be gathered, and the user can be certain that the reaction has gone to completion.
A hydrogen generator does not store vast quantities of hydrogen inside itself at any time, either during operation, or when not in use. This means that if a leak occurs, only a very small quantity of hydrogen is likely to escape.
Conversely, a full hydrogen cylinder may contain as many as 11, litres of hydrogen gas; all of which could be released if a leak were to occur. Good hydrogen generators also contain sensors to detect hydrogen and water leaks, and shut down hydrogen production when a leak is detected.

Part 2 of 3. The Hidden Costs of Gas Cylinders. Blog Home Contact Parker. February 27, by Filtration Team. Is using a hydrogen generator safe? Do I need to vent my GCs? Do I need a hydrogen sensor in the lab? Do I need a hydrogen sensor in the GC oven? Are hydrogen generators difficult to maintain? That a hydrogen generator can be easily built out of everyday items and produce enough electricity and H2 gas to power houses, vehicles and other applications could change the nature of the global economy by making electricity and power affordable and available to everyone, on or off established power grids.
Both the Energy Information Administration of the U. Government and the National Research Council of Canada maintain websites to promote and document their efforts into seeing their technology brought into its full use within the next 20 years.
Both countries support research to release the potential ability of a hydrogen generator to "recycle" chemicals and use plain water as a source for energy and make it a source for endless, renewable electricity.

Adequate airflow must be maintained around the generator to allow the ventilation system to perform efficiently. If the generator is stored in an enclosed space the environment must be controlled via an air conditioner or extraction fan.
The provision must be made to allow the volume of air in the room to be changed 5 times per hour. The vents should not be obstructed or connected to any application. Safe, forced removal of waste gases has been engineered into the generator to prevent any internal gas or pressure build-up. This is possible as long as the recommended environmental conditions required for normal operation are met. Reducing the length of pipework will reduce costs if not already installed and the risk of any potential leaks in the pipework going undetected, improving the safety of the installation.
If a customer wishes to use a fume extractor, or to connect tubing between the exhaust of the generator and a fume-hood, this is possible, but any hydrogen exhausted from the GC will quickly diffuse in the air and presents no danger to laboratory personnel or the environment.
If tubing is attached to the exhaust ports of the generator, it is essential that this is monitored frequently, since any kinks could cause a build-up of gas and cause additional health and safety issues. The lower explosive limit LEL of hydrogen is 4. The majority of laboratory environment will not be completely sealed, with air conditioning in place, allowing air movement.
If you have any concerns, Peak offers complimentary site evaluations, installation surveys and demonstrations. The risk of a significant build-up of gas in the GC oven is also extremely low, with both the external leak safety shutdown feature of the hydrogen generator and the GC inlet safety shutdown feature in place.
Should your laboratory, state government or business policy require regulation, sensors or monitoring- Peak can offer both external room and in GC oven monitoring sensors for complete peace of mind.
Maintenance is very simple, cost-effective and does not require an engineer for regular maintenance. Simply re-fill the deionized water reservoir weekly. Preventive maintenance PM is required biannually - requiring deioniser cartridge swap over. Click here to get in touch. As a typical rule of thumb, cc will supply two FID detectors. Of course, the required generator will depend on flow rate, carrier gas type, column, other detectors and unique methods.
Your gas requirement calculator can be found here. Or contact us for a consultative solution. Calculating the gas, delivery charges, cylinder rental charge, staff downtime time, administration, OHS measures and training, ROI is typically within 9 to 15 months.
