Fraunhofer IFF team designing hydrogen factory of the future

Green Car Congress

Electricity sourced from sun and wind is used to split water into hydrogen and oxygen in a process called electrolysis. It is not possible to build wind and PV plants everywhere. Micropollutants such as pharmaceuticals, pesticides and cosmetics can be removed from wastewater when ozone is introduced.

EPA Climate Change Adaptation Plan sees likely increase in tropospheric ozone, with more difficulty in attaining NAAQS in many areas

Green Car Congress

Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.

California ARB and NOAA Collaborating in $20M Research on Interaction of Air Pollution and Climate Change; One Atmosphere Approach

Green Car Congress

The project builds upon the idea that air quality and climate change issues are linked through “one atmosphere”, an approach that demands coordination and multi-tiered approaches. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs. CalNex is the culmination of three years’ preparation.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.
