绿色氢:是时候踩油门了
Renewable natural gas (RNG) or substitute natural gas (SNG) production is one of the most flexible approaches to decarbonise end demand such as residential heating and transportation systems.
由沼气产生的可再生天然气, 电力制气和生物质气化, 这是一种清洁、低碳的传统天然气替代品吗, 可以使用现有的网格基础设施进行传输和分发.
Wood’s VESTA catalytic methanation technology for natural gas production provides an efficient, 稳健和可行的系统,可以适应任何来源的合成气(如.g.(来自生物质或废物气化),包括CO2-rich gases typical for 沼气改造和电转气应用s based on green hydrogen and CO2 from other processes.
RNG is a -clean and excellent energy carrier that can be directly introduced into existing natural gas grids. The applications in the bio-based market sector include residential heating (including cooking), 热电联产和运输系统.
The biogas sector represents a production potential of renewable gas of 10 billion Nm3 到2030年,90%的生物甲烷来自农业基质,20%来自有机废物, 非生物源和气化). 生物甲烷的生产减少了温室气体的排放.
Renewable natural gas is expected to play a key role in the energy sector due to the easy connection of production plants to existing natural gas networks and the availability of mature technologies, 比如灶神星, 商业应用.
伍德开发了一种简单的甲烷化过程,称为VESTA, 由我们合作伙伴提供的高性能催化剂提供动力, 科莱恩.
VESTA enables the decarbonisation of natural gas production by exploiting renewable resources with three alternative process schemes to reduce dependency on fossil fuels and meet environmental targets:
The first pathway to produce a clean gas by using unique plant configurations (depending on the selected gasification technology) with an impact on the downstream syngas compositions and, 随后, 关于清洁步骤.
Biogas and renewable hydrogen to increase Natural Gas production and reduce CO2 emissions
CO2-rich gas conversion to green natural gas by using renewable hydrogen and a subsequent drying section.
生物质气化 plants can be economically attractive with government incentives across various regions (for example the Advanced Biofuel Feedstock Incentives or Alternative Fuel Corridor (AFC) Grants and similar programmes in the UK and continental Europe), as well as in North America or alternatively as a route to integrate and utilise low grade heat.
沼气升级和电制气系统允许RNG的最广泛使用, 不仅用于发电,还为交通运输提供了另一种选择, 所有绿色经济体的工业和家庭能源需求.
一种独特的一次性甲烷化技术
The advantage of VESTA over the other methanation methods is its full flexibility to balance both capital and operative expenditures, 以及对任何合成气来源的适应, 比如煤, 生物质或废物气化, 沼气改造和电转气应用.
与其他可用技术相比, VESTA uses a once-through process with CO2 removal performed downstream of the methanation reactors rather than before the methanation section.
This strategy eliminates the need for product recycle compressors and the associated power consumption and installation costs while prevents the risk of runaway in the Methanation section as the CO2 acts as temperature damper mitigating the High exothermicity of the process.
催化剂的伴侣
The high-performance catalyst for the methanation reactors is provided by our partner 科莱恩. 科莱恩的高稳定性, non-precious metal catalyst is ideal for the increased operating range of 230-700oC有助于取得更好的结果.
Wood has technically and economically assessed the following three SNG production pathways for small-scale and multipurpose commercial applications:
生物基行业在欧洲获得了意想不到的兴趣和投资. 考虑到当前的激励措施, biomass gasification followed by a suitable polishing step and clean gas methanation is a viable and economically attractive solution to produce RNG.
沼气升级提供了一种高效, 健壮的, 和可行的系统来生产可交付的生物制煤, 利用现有的天然气基础设施进行运输和分配.
权力-to-gas utilization is as feasible and efficient as biogas upgrading to generate clean syngas and a subsequent bio‑SNG that can be integrated into the existing natural gas networks for transportation and heating.
这是首个废物制煤示范工厂
伍德与英国政府和先进等离子体公司合作建造 首个废物转化为能源的煤制天然气工厂 使用VESTA甲烷化技术.
The ultra-clean substitute natural gas demonstration plant is funded by the UK’s Department for Transport and by National Grid Gas 分布 and built in collaboration with Advanced Plasma 权力’s Gasplasma® technology.
The plant converts biomass to syngas and then converts syngas to substitute natural gas (SNG) using Wood’s VESTA SNG technology. The installation of 灶神星甲烷化 is complete and will be fully operational in 2022.
