Across the globe, governments are betting on hydrogen, especially if it can
be produced from wind and solar power as part of the net zero transition. While some developers are racing to announce GW-scale projects that will take decades to come online, others are considering smaller scale, near-term opportunities.
In the UK, it is increasingly challenging to obtain grid connections for wind and solar farms. There is a strong case for using green hydrogen to help integrate more renewables into our energy system and avoid hefty curtailment losses during periods of high wind and low demand. The appetite for green hydrogen and other so-called ‘power-to-x’ projects fits in with a broader trend towards co-location of different renewable energy generation technologies, as well as battery storage.
In this article, we explore some of the key questions developers are grappling with. How much green hydrogen can be produced from co-located wind and solar electricity at a specific site? What is the optimal sizing for electrolyser capacity with respect to renewable generation capacity? And, to what extent can electrolysers help to mitigate renewable energy curtailment?
