Hydrogen FAQs
Using a hydrogen fuel cell, a generator can produce clean, emission-free electricity from hydrogen gas. At its most simple, a fuel cell is two areas of gas, separated by a membrane that only lets one type of particle move from one side to the other. Inside the fuel cell itself, a catalyst at the anode… Read More »How do hydrogen fuel cell generators work?
Hydrogen-fuelled internal combustion engines (ICEs) are quite similar to traditional diesel internal combustion engine generators, except that they run on hydrogen, which can be a clean and carbon-free fuel. Unlike hydrogen fuel cell generators, hydrogen internal combustion engine generators are not completely emission-free. They can still emit a small amount of CO2 (from air and… Read More »How do hydrogen internal combustion engine generators work?
How much carbon footprint is associated with the usage of hydrogen depends on its source. While hydrogen is emission-free at the point of use, carbon can be released to the atmosphere during its production. For the purpose of this question, let us focus on three types of hydrogen production techniques: Green hydrogen produced by electrolysis… Read More »How green is hydrogen?
Battery technology is a great way of reducing on-site emissions for low-power, lightweight uses. But for a battery to be usable, it must be recharged. For off-grid applications where high energy output is required, a battery solution with enough capacity will prove too bulky and expensive, and would also need to be transported off site… Read More »How does hydrogen compare with battery solutions?
Hydrogen has been used widely at scale in industries for decades, and its health and safety risk is well understood. The use of hydrogen needs to be assessed according to regulations focussing on dangerous substances and explosive atmospheres, and simple design constraints and operational precautions can be put in place to mitigate risks. Hydrologiq has… Read More »What are the health and safety aspects regarding hydrogen?
