A new report released by research company IHS Markit explains the role gas can play in the transition to net-zero.
The report, A Sustainable Flame: The Role of Gas in Net Zero, states that gas has a significant part in both the near-term and long-term energy decarbonisation targets owing to the ability of the existing infrastructure to be converted to carry low-carbon fuels including ammonia, hydrogen, synthetic methane and renewable natural gas.
The report says more emphasis is needed on the repurposing of existing infrastructure to enable gas to become a 'second pillar' of decarbonisation alongside renewables.
For instance:
- Pipelines, both transmission and distribution, can ship renewable natural gas. In an early stage, they can blend in 'green' gases to lower the carbon footprint, while in the longer term they can be repurposed for shipping of 100% hydrogen. So too with much of gas storage infrastructure.
- Gas-fired power plants can convert to run on hydrogen or sustainable ammonia, or in some circumstances can retro-fit carbon capture, utilisation and storage (CCUS).
- Liquefaction plants can be converted to liquefy hydrogen, likely at a lower cost than building a liquefied hydrogen plant from scratch.
- Industrial and domestic gas boilers can be manufactured to be readily adaptable from natural gas to hydrogen.
