The broader impact /commercial potential of this Small Business Technology Transfer (STTR) Phase I project is to derisk a new membrane manufacturing technology for biogas upgrading. Renewable natural gas (RNG) is attractive as a carbon neutral energy source as it is derived from organic wastes such as food waste, agricultural waste, and municipal biosolids. RNG is part of biogas and requires cost- and energy-effective separation from carbon dioxide. The company has developed an additive manufacturing technology that enables the fabrication of high performance membranes to enable lower cost biogas upgrading. These membranes offer energy and system design benefits over more traditional separations technologies for the production of RNG. The membrane printing approach may lead to the production of best-in-class membranes for RNG production and could enable carbon capture and utilization from biogas sources.This Small Business Technology Transfer (STTR) Phase I project seeks to demonstrate the production of mixed matrix membranes (MMMs) comprised of polyether block amide polymer and zif8 zeolite. The proposed method uses electrospray based additive manufacturing to precisely control membrane thickness and zeolite loading, allowing customized membrane properties for biogas upgrading. Furthermore, the additive manufacturing, or printing, method enables increased loading of the zeolite over conventional casting techniques without the formation of defects that would lessen selectivity. The goals of the project include quantification of the maximum zeolite loading while avoiding loss of selectivity. The company will produce small membrane leaves up to 1 ft2 in area and demonstrate consistent performance across the leaf using mixed gas testing.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该小型企业技术转移（STTR）I阶段项目的更广泛的影响 /商业潜力是为沼气升级的新膜制造技术剥夺。 可再生天然气（RNG）作为碳中性能源具有吸引力，因为它源自有机废物，例如食物浪费，农业废物和市政生物固体。 RNG是沼气的一部分，需要与二氧化碳的成本和能量有效分离。 该公司已经开发了一种增材制造技术，该技术使高性能膜的制造能够降低成本的沼气升级。 这些膜为生产RNG提供了能量和系统设计优势。膜印刷方法可能导致生产最佳的RNG生产膜，并可以从沼气来源捕获和利用碳捕获和利用。该小型企业技术转移（STTR）I阶段项目旨在证明由混合矩阵膜（MMMS）生产由聚醚嵌段的混合基质膜（MMMS）。 提出的方法将基于电喷雾的添加剂制造用于精确控制膜厚度和沸石载荷，从而允许自定义的沼气升级膜特性。此外，添加剂制造或打印方法可以使沸石的负载超过传统铸造技术，而不会形成缺陷，从而降低了选择性。 该项目的目标包括量化最大沸石载荷，同时避免选择性丧失。该公司将在区域生产高达1 ft2的小膜叶，并使用混合气体测试在整个叶子上表现出一致的性能。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响评估标准，认为值得通过评估来获得支持。
