Electricity represents the largest cost driver for green hydrogen. Power consumption can be adjusted to follow actual solar and wind output, which vary with different seasons, times of day and weather conditions.
Electrolysers split water into hydrogen and oxygen. Their biggest cost driver is electricity. With the best possible renewable resources, green hydrogen could almost compete on costs with other energy types today.
Electrolyser loads can adjust economically with solar and wind supply, which can vary by season, time of day and weather conditions. But the costs of building and operating electrolysers also make a difference. In the coming decade, electrolyser cost reduction strategies could further narrow the gap – and broaden the range of feasible, cost-effective locations for green hydrogen uptake.
