The objective of this report is to reflect the state of the U.S. market demand for “BRTheavy” vehicles and systems, with a focus on “BRT-heavy” vehicles and systems. It is the third is a series of market demand analyses and as such, charts the trends in this evolving market. Via phone interviews and electronic surveys of transit planners, and also via published reports from the transit properties and industry publications, the report compiles data about the quantities of vehicles, delivery timing, and vehicle preferences such as vehicle type, length, propulsion, image, and appearance, as well as supporting technologies such as signal priority. An aggregate view is developed about the features in BRT vehicles and systems implied by the community transit plans now and in the near future. Implications are drawn from the community interviews and analysis results. What emerges is a perspective on the vehicle features desired to support BRT plans, the quantities and timing of vehicles with these features, and a set of proximate topics that may be important for future industry dialog.

This report provides information on activities related to hydrogen internal combustion engines (HICE) and hydrogen-blend gaseous fueled internal combustion engines (HBICE). Hydrogen is an attractive fuel for vehicle power and other applications because it produces an exhaust that is nothing but water vapor, with other emissions controllable to near zero levels eliminating air pollution and no carbon dioxide to exacerbate climate change. Hydrogen can be burned in a more-or-less standard internal combustion engine but applicable technology for improvement of performance, thermal efficiency and emissions are available in the near term. This compendium documents a number of heavy duty drivetrain developments. This document provides some visibility into pertinent activities being performed at U.S. federal government agencies that relate to technology developments for internal combustion engines fueled by hydrogen or hydrogen-blends. Important activities are also being performed at the state and local levels and in the private sector. Some automobile manufacturers are pursuing HICE production vehicles research. Likewise, some private concerns aspire to enter smaller niche markets such as off-road vehicles on airports or stationary power generation.

This report represents one part of an effort to provide information to the U.S. transit
authorities on activities related to hydrogen internal combustion engines (HICE) and
hydrogen-blend gaseous fueled internal combustion engines (HBICE). Scientists are focusing on the use of hydrogen as a source of energy. Hydrogen is an attractive fuel for automotive power and other applications because it produces an exhaust that is nothing but water vapor, with other emissions controllable to near zero levels eliminating air pollution and no carbon dioxide to exacerbate global warming. Hydrogen can be burned in a more-or-less standard internal combustion engine but applicable technology for improvement of performance, thermal efficiency and emissions are near term.
