To move to a more sustainable energy mix and decarbonise heat an increasing proportion of gas used in homes will need to come from renewable sources. A major contribution could come from AD (anaerobic digestion) plants that produce bio-methane from waste and inject directly into the gas network. However, these plants need to be connected into the lower tiers of the network. At times of low demand, the networks can have insufficient injection capacity to take all the gas that could be produced. This leads to AD plants reducing output or having to flare surplus gas. Furthermore, applications to connect new AD plants can be turned down due to a lack of injection capacity on that part of the network. A solution to this problem is to use the network as storage increasing the pressure at times of surplus production to store excess biomethane and dropping the pressure when demand once more exceeds production of biomethane. However, this requires a retrofitable smart control solution because the governors feeding the networks are currently all manually adjusted. Utonomy has already developed an innovative retrofitable pressure management solution to control LP (low pressure) networks. This new project aims to modify the actuator design and develop the software to control the MP (medium pressure) networks to which AD plants are connected. Trials will be carried out on a part of the UK network fed by a biomethane plant and measure the increase in output of the plant over a 12 month period.

为了实现更可持续的能源组合和脱碳，家庭使用的天然气中越来越多的比例需要来自可再生能源。一个主要的贡献可能来自AD（厌氧消化）工厂，这些工厂从废物中生产生物甲烷，并直接注入天然气网络。然而，这些工厂需要连接到网络的较低层。在需求低的时候，网络可能没有足够的注入能力来吸收所有可能生产的天然气。这导致AD工厂减少产量或不得不燃烧多余的气体。此外，连接新的AD工厂的应用程序可能会由于网络的该部分缺乏注入能力而被拒绝。该问题的解决方案是使用网络作为存储，在过剩生产时增加压力以存储过量的生物甲烷，并且在需求再次超过生物甲烷的生产时降低压力。然而，这需要一个可改造的智能控制解决方案，因为为网络供电的调速器目前都是手动调节的。Utonomy已经开发出一种创新的可改造压力管理解决方案来控制LP（低压）网络。这个新项目的目的是修改执行器的设计和开发软件，以控制AD工厂连接的MP（中压）网络。试验将在英国网络的一部分进行，由一家生物甲烷工厂提供燃料，并测量该工厂在12个月内的产量增长。
