Could carbon capture be the key to decarbonising heavy industry?
脱碳 is key to addressing the serious risks posed by climate change and designing a low carbon future. As our clients focus on solutions for 排放 abatement, alternative energy sources will be crucial in the drive to deliver a more sustainable future energy mix.
氢, when used as a fuel, emits zero CO2 and can be utilised for low-carbon energy storage which is leading to new value chains for transporting and consuming hydrogen in various forms like ammonia, 甲醇, 和甲烷.
However, one significant challenge lies in the 生产 of hydrogen itself. The most common method, 蒸汽转化, produces substantial amounts of carbon dioxide as a by-product. 为了解决这个问题, Wood experts are exploring the potential of blue hydrogen, which combines hydrogen 生产 with carbon capture systems to mitigate CO2 排放.
Our team identified four innovative approaches to decarbonising existing hydrogen 生产 units based on 蒸汽转化, which could drastically reduce carbon 排放, capital expenditure, operational costs and project implementation time compared to the conventional approach of capturing carbon post-combustion.
The four options we identified are:
- BlueSMR +: Introducing pre-combustion carbon capture, a gas heated reformer, and a pre-reformer to significantly enhance unit performance. 氢-rich gas firing will also displace the CO2 排放 from the combustion side of the process.
- BlueSMR +: Similar to option 1, but with an improved catalyst tube geometry in the reforming furnace, potentially leading to reduced operating costs.
- BlueSMRp: Utilising Wood’s proprietary BlueSMRp technology, this option involves installing a separate, parallel hydrogen 生产 unit with pre-combustion carbon capture to provide low-carbon fuel for the existing unit.
- BlueSMRe: Integrating renewable electric power to decrease fuel consumption and CO2 生产.
The conclusion is clear, all four solutions offer substantial reductions in CO2 排放, paving the way for a more sustainable hydrogen 生产 process, and through deploying innovative decarbonisation techniques ahead of combustion, existing hydrogen 生产 facilities can play a crucial role in the drive towards a sustainable future. This will be crucial for many industrial sectors like refineries and steel 生产 where other low-carbon alternatives are less feasible.
