Project summary description:
The overall goal of the project is to understand the specific global and regional impacts of a shift to a hydrogen economy over the coming decades.

Global impacts on atmospheric composition (oxidative capacity), methane lifetime, impact on stratospheric water vapour and stratospheric ozone (and ozone layer recovery), and global temperature / climate (e.g. avoided warming) are being investigated for a range of hydrogen uptake scenarios spanning the coming decades.

At the regional scale, the goal is to set up a capability for undertaking a national health impact analysis of the air quality impacts of moving to a hydrogen economy. The regional and global models will be coupled at the regional model boundaries.

Future emission scenarios for use in the modelling systems are being developed by Climate Resource Pty Ltd and will span the period from present day to 2100, and a range of low- to high-uptake scenarios.

The modelling activities will be crucially underpinned by continuing high-precision in situ monitoring of hydrogen at both Cape Grim (NW Tasmania) and Aspendale (Melbourne, Vic). An additional hydrogen monitoring capability is being developed at Clayton (Melbourne, Vic). CSIRO also has an ongoing long-term (30 years) global background hydrogen record from flask measurements.
