SBIR Phase II: Hydrogen from Hydrogen Sulfide

这项小企业创新研究（SBIR）二期项目的广泛影响/商业潜力将对科学技术、国家减排努力和美国的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，从硫化氢中生产氢，这是一种在能源供应链中发现的常见废物。这项技术将有助于减少温室气体排放和空气污染，并有助于改善采用这项技术的工业场所附近社区的公共卫生。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，例如炼油厂的氢气生产。实施这项技术将为炼油厂提供一个现场，从废物流中低排放的氢源，降低成本和排放。最终，这一创新将使国内生产的低排放氢能源成为可能，从而加强美国的能源安全。这个小型企业创新研究第二阶段项目建议开发一种化学循环，从硫化氢中产生氢。这一努力代表了一种为大型、成本敏感型公司量身定制的替代制氢技术。尽管目前的氢气生产急需脱碳，但低排放技术的市场采用已经停滞，因为它们的成本阻碍了商品化学品的使用。该项目旨在通过使用硫化氢（一种丰富的低价值废物流）作为化学循环的原料来打破这一趋势，从而产生氢气，而不会产生大量温室气体排放。该项目将有几个技术上具有挑战性的目标，包括优化工艺，以处理高数量级的硫化氢浓度与几种高活性和腐蚀性杂质的混合，以及研究和开发复杂工艺混合物的产品分离。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处理设施的复杂结构中。虽然已经在其他市场得到验证，但实验和建模任务将测试该技术在炼油厂废物流上的性能，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导致炼油厂的示范工厂。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值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.
