Yes, an electrolyzer from Batarow Hydrogen is safe. Every electrolyzer we manufacture is CE certified. Our engineers conscientiously observe all applicable safety guidelines during the design phase. In addition, we only use components from reputable manufacturers. Extensive testing has verified and confirmed the safety and reliability of each type of system. To ensure proper functioning, each electrolyzer is monitored by our specially developed control software. All safety- and system-relevant parameters are constantly monitored so that the system can independently influence them if necessary. In the event of a malfunction, the electrolyzer switches itself off automatically. In addition to software monitoring, we also use additional mechanical safety devices for particularly critical parameters.   Hydrogen vs. gasoline The most important difference between hydrogen and gasoline is that hydrogen is a gas and gasoline is a liquid. Hydrogen is the lightest element on earth, which is a major advantage in terms of safety. This is because the fuel evaporates very quickly in the air and can only be ignited for a very short time. Gasoline, on the other hand, evaporates more slowly and still has a higher density than air. Gasoline vapor therefore often remains on the ground for a long time, where it is most likely to ignite. Another key point is the question of under what conditions a fuel-air mixture explodes – for example, if fuel leaks after an accident or due to a leak. The fundamental disadvantage here is that hydrogen can ignite in a very wide concentration range of four to 75 percent. However, only the lower limit is really significant, i.e., the four percent hydrogen in the air at which the mixture can ignite. However, hydrogen is highly likely to burn off before an explosive mixture can even form, as this requires at least 18 percent hydrogen in the air. With gasoline, on the other hand, this detonation limit is only 1.1 percent by volume, which means that gasoline vapors explode more easily than hydrogen. In order for an explosion or fire to occur in either case, a fuel-air mixture must first be ignited. In the case of hydrogen, this requires less energy than gasoline—however, the energy of an electric spark is sufficient to ignite even gasoline vapors. This makes refueling gasoline vehicles fundamentally risky. On the other hand, hydrogen has a higher ignition temperature than gasoline, which means that gasoline can ignite much more easily than hydrogen on hot surfaces, such as the catalytic converter or the exhaust manifold.   Source: Dr.-Ing.
