This interactive webapp can be used to reproduce figures from an accompanying article by the same authors that studies the cost competitiveness of blue and green hydrogen. Some of the key assumptions (e.g. methane leakage, electricity prices, electrolyser CAPEX, gas prices) can be changed here when generating the figures.

We employ techno-economic and life-cycle assessments to compute the levelised costs and greenhouse-gas intensities of competing production technologies for blue (from natural gas with CCS) and green (from renewable electricity via electrolysis) hydrogen. This allows us to determine fuel-switching CO2 prices (FSCPs), defined by the carbon price at which fuels with lower emissions become cost competitive with fuels with higher emissions.

Using these metrics, the presented figures compare the cost, greenhouse-gas intensities, and resulting FSCPs of competing fuels and technologies over the studied time range (2025 to 2050). These figures allow us to study whether and when green hydrogen becomes cost competitive with blue hydrogen. Our results demonstrate that the long-term competitiveness of blue hydrogen and its viability as a bridging option crucially depend on natural-gas prices and on residual emissions (non-captured CO2, upstream supply-chain CH4 and CO2).

For more advanced changes and detailed information on the input data and methodology, we encourage users to inspect the article, its supplement, and the source code written in Python.
