The potential for bulk green hydrogen and the role of power-to-gas
Recent dramatic falls in the cost of renewable electricity generation offer the potential for bulk green hydrogen through electrolysis at costs which are competitive with fossil fuels. This has tangible benefits for the whole energy system, including inter-seasonal or short term energy storage and targeting end use to the most difficult to decarbonise sectors. In this paper we discuss the cost trajectory of bulk green hydrogen production and provide pointers to where and how it can become cost competitive with existing fossil fuel sources. We highlight recent moves to explore the re-purposing of existing gas networks to accommodate hydrogen and discuss how power to gas demonstrations are allowing the benefits and barriers of such an approach to be explored.
