SBIR Phase II: Hydrogen from Hydrogen Sulfide

这一小型企业创新研究(SBIR)第二阶段项目的更广泛影响/商业潜力将对美国的科学技术、国家减排努力和能源安全产生重大影响。该团队的目标是通过开发一种低成本、低排放的方法来从硫化氢中生产氢气来推动科学发展。硫化氢是一种常见的废物，在能源供应链中随处可见。这项技术将有助于减少温室气体排放和空气污染，并有助于改善采用该技术的工业场地附近社区的公共健康。从商业角度来看，该项目有可能降低美国制造的能源产品的成本和碳排放，比如炼油厂的氢气生产。实施这项技术将为炼油厂提供来自废气的现场低排放氢源，从而降低成本和排放。最终，这项创新将通过实现国内生产的低排放氢能来增强美国的能源安全。这个小企业创新研究第二阶段项目提议开发一种从硫化氢中产生氢气的化学循环。这一努力代表了一种为对成本敏感的大型公司量身定做的替代氢气生产技术。尽管目前的氢气生产迫切需要脱碳，但市场对低排放技术的采用已经停滞不前，因为它们的成本阻碍了在商品化学品中的使用。该项目旨在打破这一趋势，将硫化氢作为化学循环的原料，在不排放大量温室气体的情况下产生氢气。硫化氢是一种丰富的低价值废物。该项目将有几个具有技术挑战性的目标，包括优化工艺，以处理高达数量级的硫化氢浓度与几种高活性和腐蚀性杂质的混合，以及研究和开发从复杂工艺混合物中分离产品。此外，该项目将筛选材料和催化剂，并准备将该过程整合到现代化学加工设施的复杂结构中。虽然已经在其他市场进行了验证，但实验和建模任务将测试该技术在炼油厂废液中的性能，并为更大规模的工业现场演示做准备。预计该项目的完成将直接通向炼油厂现场示范工厂。这一奖励反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project will make a significant impact on science and technology, national emission reduction efforts, and the energy security of the United States. The team aims to advance science by developing a low-cost and low-emission method to produce hydrogen from hydrogen sulfide, a common waste product found throughout the energy supply chain. This technology will help to reduce greenhouse gas emissions and air pollution and contribute to improving public health in communities near industrial sites that adopt this technology. From a commercial perspective, the project has the potential to lower costs and carbon emissions of energy products made in the United States, such as hydrogen production in oil refineries. Implementing this technology would provide refineries with an onsite, low-emission source of hydrogen from waste streams, reducing costs and emissions. Ultimately, this innovation will enhance the energy security of the United States by enabling domestically produced, low-emission hydrogen energy.This Small Business Innovation Research Phase II project proposes to develop a chemical cycle that generates hydrogen from hydrogen sulfide. This effort represents an alternative hydrogen production technology tailored to large, cost-sensitive firms. Despite the significant need to decarbonize current hydrogen production, market adoption of low-emission technologies has stalled because their cost precludes use in commodity chemicals. This project aims to break this trend by using hydrogen sulfide, an abundant low-value waste stream, as a feedstock for a chemical cycle that generates hydrogen gas without significant greenhouse gas emissions. The project will have several technically challenging objectives including optimizing the process to deal with orders of magnitude higher hydrogen sulfide concentrations mixed with several highly reactive and corrosive impurities and researching and developing product separations from complex process mixtures. Additionally, the project will screen materials and catalysts and prepare the process for integration into the complex structure of a modern chemical processing facility. While already validated for other markets, the experimental and modeling tasks will test the performance of the technology on refinery waste streams and prepare for larger-scale, industrial site demonstrations. It is anticipated that the completion of this project will lead directly into a refinery site demonstration plant.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.
