据油气新闻6月22日消息称，想想象一下，如果你想要一种不受时间和天气限制的可再生能源。一种可再生能源，其表面的潜力刚刚被挖掘出来。也也许在当今的政治环境中，最重要的是，可再生能源的来源不依赖于敌对国家主导的供应链作为其原料来源，而是依赖于美国的家庭农场。
这正是先锋可再生能源公司及其新任首席执行官Joel Gay从事的业务。该公司专注于将粪便和食物垃圾转化为可再生天然气(RNG)。RNG生产后剩下的部分会被转化为有机肥料，将产生的粪便和食物垃圾中的营养物质返回土壤进行再次循环利用，并将成吨的废物转移到垃圾填埋场或焚化炉。
RNG是第一个碳负能量来源，因为它是由有机物产生的，否则会被释放为强大的温室气体。因此，先锋公司正在帮助星巴克和联合利华等公司实现“到2050年实现净零排放”的承诺。这一承诺在主要能源和消费品公司中已成为一种时尚。
对每个人来说，好消息是这个行业在很大程度上具有可扩展性。先锋公司由两位企业家于2014年创立的，已经在美国50个州中的17个州有农场在开发中，并且正在着手一项大规模扩张的计划。为了管理公司的扩张，公司刚刚宣布招聘新的首席执行官Joel Gay。
先锋公司已经是全国厌氧消化生产 RNG 的最大企业之一，将在这一增长中发挥主导作用。Gay表示：“就增长潜力而言，它是相对无限的。”
他说:“业务分为有机和农业两大类。在有机方面，我们结合了粪便和有机可回收材料——这是不合格的食品，变质的食品，有机液体或有机固体。我们将所有这些混合成均匀的浆液，然后送入我们的厌氧消化池。因此，在有机方面，我们最终得到大概是两种肥料和八种有机材料的结合。”
Gay 说，目前的商业模式是针对大型城市中心，这些中心有各种有机材料的来源——餐馆、杂货店等——可以聚集成足够大的数量，以创造规模经济。

Renewable Natural Gas Set For Disruptive Growth
Imagine if you will a renewable source of energy without constraints of time of day or weather. A renewable source of energy whose surface of potential is just now being scratched. Perhaps most importantly in today’s political environment, a source of renewable energy that does not rely on supply chains dominated by adversarial nations as the source of its feedstock, but America’s family farms instead.
That is the line of business in which Vanguard Renewables and its new CEO, Joel Gay, are engaged. It is a business focused on converting manure and food waste into renewable natural gas (RNG). What remains following the production of RNG is then turned into organic fertilizer, returning the nutrients from the manure and food waste produced back to the soil to be recycled again and diverting tons of waste that would have otherwise gone into landfills or incinerators.
RNG is the first carbon-negative energy source since it is produced from organic matter that would otherwise be released as a powerful greenhouse gas. As a result, Vanguard is helping companies like Starbucks and Unilever meet their “net-zero by 2050” pledges that have become a fad among major energy and consumer goods companies.
The positive news for everyone is that this industry is scalable in a major way. Vanguard, which was founded in 2014 by a pair of entrepreneurs, already has farms in development in 17 of the 50 U.S. states and is embarking on a plan for major expansion. To manage that expansion the company just announced the hiring of a new Chief Executive Officer, Joel Gay.
Vanguard, already one of the biggest players in the production of RNG by anaerobic digestion nationally, stands to play the leading role in that growth. “In terms of the growth potential, it is relatively unlimited,” Gay said.
“The business is bifurcated between organic and Ag. On the organic side, we are combining both manure and organic recyclable material – this is off-spec food, spoiled food, organic liquids or organic solids. We combine all of those into a homogenous slurry, which is then fed to our anaerobic digesters. So, on the organic side, we end up with roughly 2 parts manure combined with 8 parts organic materials.”
Gay said that currently the business model is to target big urban centers with a variety of sources for this organic material – restaurants, grocery stores, etc. – that can be aggregated into large enough volumes to create economies of scale.
