Switching a city from natural gas to hydrogen - DNV GL

Figure 2: Existing gas network infrastructure can transport natural gas, which is mostly methane (CH4), and a methane/hydrogen (H2) mix. The H21 Leeds City Gate project proved it would be feasible to convert the UK city's natural gas network to H2 supplied by steam methane reforming and stored in onshore salt caverns.

The future of the UK gas network - ScienceDirect

We examine the long-term future of the UK gas pipe networks using the UK MARKAL model. • The iron mains replacement programme will not lead to gas infrastructure lock-in. • Bio-methane and hydrogen injection have only a small role in our future scenarios. • The most cost-optimal strategy might be to convert the networks to deliver ...

Biomethane - an overview | ScienceDirect Topics

Wolfgang Urban, in The Biogas Handbook, 2013. Abstract: Biomethane is a flexible and easily storable fuel that can be used wherever natural gas is used without the need to change any settings on equipment designed to use natural gas. In regions where a natural gas grid already exists, there is a ready-made system for the distribution of biomethane.

Power-to-gas - Wikipedia

The power to methane method is to combine hydrogen from an electrolyzer with carbon dioxide and convert the two gases to methane (see natural gas) using a methanation reaction such as the Sabatier reaction or biological methanation resulting in an extra energy conversion loss of 8%, [citation needed] the methane may then be fed into the natural ...
