Solid organic waste is a potentially large, decentralized and sustainable source of hydrogen. The potential hydrogen yield from the anaerobic digestion of solid organic waste in Sydney alone could power over 750,000 passenger vehicles. Hydrogen is always generated in the digestion of organic material, but under natural conditions it is scavenged by methanogens. Recently developed silica membranes are selectively and highly permeable to hydrogen, and these can be used to draw hydrogen from the digester. The digester will be run at high temperatures (>65oC) because this favours organisms that produce hydrogen over methanogens. Anaerobic digesters are well established in Europe and at least 3 municipal plants already exist in Australia.

固体有机废物是一种潜在的大型，分散和可持续的氢源。 仅在悉尼，固体有机废物厌氧消化产生的潜在氢气就可以为75万多辆乘用车提供动力。 氢总是在有机物的消化中产生，但在自然条件下，它被产甲烷菌清除。 最近开发的二氧化硅膜对氢气具有选择性和高渗透性，并且这些膜可用于从消化器中提取氢气。 消化器将在高温（> 65 ℃）下运行，因为这有利于产生氢气的生物体而不是产甲烷菌。 厌氧消化器在欧洲已经很成熟，在澳大利亚至少有3个市政工厂。
