A couple of years ago, I virtually bought an electrolyser and base-load power.

I use this (virtual) electrolyser only when the day ahead power price is so low that green hydrogen is cheaper than blue or grey hydrogen at marginal costs.
If not, I sell the power to the power market.

This year, so far, the percentage of hours using the electrolyser is around 11%; an increase by 25% compared to last year.

The current market share of solar & wind is about 40%; it will increase to 85% in 2030.
