Abstract

The Community Scenarios Of Hydrogen Energy And Impacts On Air Pollution (COSHAIR) examines a range of scenarios from 01/01/2020 to 01/01/2050 with different levels of hydrogen take-up, in different sectors, to understand the consequences for air pollution. The scenarios investigate the potential implications of hydrogen production and use in the energy system on UK air pollution. These scenarios were produced using the UK TIMES energy system model at University College London. This represents all substantive UK energy flows and greenhouse gas emissions.
The UK Integrated Assessment Model (UKIAM) at Imperial College was used to examine the changes in air quality that might occur in the future due to adopting hydrogen in the scenarios.
Data contains the ASCII files, compatible with QGIS, for the spatially apportioned UK concentrations of PM2.5 (particulate matter with a diameter of 2.5 micrometres or less) and NO2 (Nitrogen Dioxide) using the UKIAM framework.
The supporting information provides full descriptions of the scenario names:

NDB - No Decarbonisation Baseline (no hydrogen, non-net zero)
NZC - Net Zero Counterfactual (net zero, no hydrogen)
LS - Likely Scenario (net zero, limited hydrogen)
LPS - Likely and Possible Scenario (net zero, higher hydrogen)
US - Unlikely Scenario (net zero, highest hydrogen)

When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record.
Data lineage:

- Activity data produced from UK TIMES
- Emission factors applied to activity data - predominantly emission factors from the National Atmospheric Emissions Inventory as well as comprehensive review of emission factors for hydrogen energy
- Non-energy emissions sources taken from National Atmospheric Emissions Inventory baseline projections to 2040, carried forward to 2050
- Emissions files fed into UKIAM for different scenarios and years

Data Quality:
Emission factors used were either from official, ratified emissions inventories or were from a comprehensive review of the literature for new and emerging technologies, such as hydrogen production and use. These emission factors are to be published in a comprehensive review paper, but are also included in the report appendix.

Title

UK Integrated Assessment Model (UKIAM)

Abstract

UKIAM has been designed to study future air pollution abatement scenarios in the UK. It works at a 1 km resolution and can map how air quality might vary across the country in the future with associated assessment of health impacts and economic costs. UKIAM has previously been used by Defra for the PM2.5 target setting for 2040.
