Researchers at the Fraunhofer IFF in Germany are designing the distributed and modular production and distribution of green hydrogen for industry, business and transportation throughout the value chain—a hydrogen factory of the future. The hydrogen factory of the future. The outcome is always green hydrogen.

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. Hydrogen interacts with various biogeochemical processes.

Depletion of fresh water reserves [m 3 ]. Deterioration of the ozone layer [kg CFC-11-eq.]. The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climate change [kg CO 2 -eq.]. Depletion of fossil energy resources [kg oil-eq.]. Depletion of metal resources [kg iron-eq.].

A) shows the base case peak concentrations for O 3 (ozone), ClNO and HCl in parts-per-billion by volume (ppbv). (B) Under extreme circumstances, this previously unknown chemistry could account for up to 40 parts per billion (ppb) of ozone; the current US Environmental Protection Agency (EPA) 8-hour average standard is 75 ppb.

Previously, the fact that these compounds are water-soluble never presented any problems since the Atacama Desert is one of the driest regions in the world. Alternative oxidation processes resulting in more stable and less toxic arsenic 5+ compounds instead of unstable and water-soluble arsenic 3+ compounds are also being considered.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? about 0.6 °C.
