Abstract

Abstract Current U.S. government policy seeks to achieve a carbon-free economy by 2050, with a carbon-free electricity sector by 2035 (per executive orders #14008 and #14057). To address these goals, the U.S. Department of Energy is evaluating technologies that support the production, utilization, transport, and storage of hydrogen (via initiatives like DOE's Energy Earthshots and various DOE funding opportunity announcements). A carbon-free fuel like hydrogen is valuable for a dynamic electric energy sector seeking to decarbonize. One of the most important technologies needed to achieve this carbon-free electricity sector is a 100% hydrogen-fueled gas turbine. Accommodating hydrogen fuels has been a key goal for various original engine manufacturers (OEMs) for many years, but more research and development (R&D) is needed. The purpose of this paper is to highlight the current state-of-the- art of hydrogen turbine technology, especially regarding nitrogen oxide (NOX) emissions, compared to natural gas turbines. NOX is the primary criteria pollutant from thermally-driven combustion turbines and should be controlled to levels that are below current standards. This paper provides an overview of hydrogen as a fuel and various NOX control techniques that are relevant for hydrogen-based fuels. A conclusion from this overview is that, with some level of R&D, NOX emissions from hydrogen-fueled gas turbines can be controlled to levels similar to those produced by state-of-the-art natural gas-fueled combustion turbines while remaining competitive in terms of performance and efficiency.

当前和未来最先进燃气轮机Nox排放的文献综述

当前美国政府的政策旨在到2050年实现无碳经济，到2035年实现无碳电力部门(根据行政命令#14008和#14057)。为了实现这些目标，美国能源部正在评估支持氢气生产、利用、运输和储存的技术(通过能源部的能源地球拍摄和各种能源部资助机会公告等举措)。像氢这样的无碳燃料对于寻求脱碳的动态电力能源部门是有价值的。实现无碳电力行业所需的最重要技术之一是100%氢燃料燃气轮机。多年来，氢燃料一直是各种原始发动机制造商(oem)的关键目标，但还需要更多的研究和开发(R&D)。本文的目的是强调目前的最先进的氢轮机技术，特别是在氮氧化物(NOX)排放方面，与天然气涡轮机相比。氮氧化物是来自热驱动燃烧涡轮机的主要标准污染物，应控制在低于现行标准的水平。本文概述了作为燃料的氢和与氢基燃料相关的各种氮氧化物控制技术。从这一概述中得出的结论是，通过一定程度的研发，氢燃料燃气轮机的氮氧化物排放可以控制在与最先进的天然气燃料燃烧涡轮机相似的水平，同时在性能和效率方面保持竞争力。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
