Alternative fuels to reduce the carbon impact in the natural gas value chain

Fueling the low-carbon economy

可再生天然气(RNG)或替代天然气(SNG)生产是实现住宅供暖和运输系统等终端需求脱碳的最灵活方法之一.

Renewable natural gas produced from biogas, power-to-gas and biomass gasification, is a clean and low-carbon alternative to conventional natural gas, that can be transported and distributed using the existing grid infrastructure.

Wood的VESTA催化甲烷化技术为天然气生产提供了一种高效的方法, 健壮的 and viable system that can be adapted to any source of syngas (e.g., from biomass or waste gasification), including the CO2-富气，通常用于沼气升级和基于绿色氢气和其他过程产生的二氧化碳的电力制气应用.

Clean energy for heating, power and transportation

可再生天然气是一种清洁、优良的能源载体，可直接引入现有的天然气管网. 生物基市场领域的应用包括住宅供暖(包括烹饪)。, cogeneration and transportation systems.

The biogas sector represents a production potential of renewable gas of 10 billion Nm3 of biomethane by 2030 (90% from agriculture matrices and 20% from organic wastes, non-biogenic sources and gasification). The production of biomethane delivers a reduction in greenhouse gas emissions.

由于生产工厂易于与现有天然气网络连接以及成熟技术的可用性，可再生天然气预计将在能源领域发挥关键作用, 比如灶神星, for commercial applications.

Wood developed a simple methanation process called VESTA, powered by a high-performance catalyst from our partner, 科莱恩.

它是如何工作的

VESTA通过三种替代工艺方案利用可再生资源，减少对化石燃料的依赖，实现天然气生产的脱碳:

Biomass gasification
1. Biomass gasification

第一种途径是通过使用独特的工厂配置(取决于所选择的气化技术)来生产清洁气体，这将对下游合成气成分产生影响, 随后, on the cleaning steps.

2. 沼气升级

沼气和可再生氢气，以增加天然气产量，减少二氧化碳排放

沼气升级
电力转天然气
3. 电力转天然气 (renewable hydrogen and CO2-CO)

CO2通过使用可再生氢气和随后的干燥段将富天然气转化为绿色天然气.

在不同地区的政府激励下，生物质气化工厂在经济上具有吸引力(例如，先进生物燃料原料激励或替代燃料走廊(AFC)赠款以及英国和欧洲大陆的类似计划)。, 在北美也是如此，或者作为一种整合和利用低品位热量的途径.

沼气升级 and power-to-gas systems allows the widest use of RNG, not only for power generation but to provide an alternative for transport, industrial and domestic energy demands in all green economies.
