ABSTRACT
Previous chapters have described the need, methods, and engineering approaches for developing hydrogen storage systems for a variety of emerging hydrogen-powered applications, such as fuel cell light-duty vehicles, portable power, and construction equipment. The field testing and deployment of these systems have required the establishment of hydrogen technology “codes and standards.” Codes and standards developed by industry enable the coordinated commercial deployment of a technology. They specify interfaces and expectations for operation so that components and systems made by diverse suppliers will work together. They also specify requirements for safe design, operation, and test standards for certifying performance. Regulations developed by governments specify
