Energy

Hydrogen is already widely produced and used, but it is now being considered for use as an energy carrier for stationary power and transportation markets. Approximately 10-11 million metric tonnes of hydrogen are produced in the US each year, enough to power 20-30 million cars or 5-8 million homes.1 Major current uses of the commercially produced hydrogen include oil refining (hydro-treating crude oil as part of the refining process to improve the hydrogen to carbon ratio of the fuel), food production (e.g., hydrogenation), treating metals, and producing ammonia for fertilizer and other...

Hydrogen is a widely produced and used commodity, now being used as an energy carrier for stationary power and transportation markets. Tens of millions of tons of hydrogen are produced each year globally, mostly for large-scale industrial uses. As awareness grows for the need to reduce greenhouse gases and enable new energy paradigms, hydrogen is being seen as playing a critical role as shown in Fig. 1 [1]. Hydrogen provides chemical storage of electrical energy and can be efficiently converted to electricity on demand for distributed applications, thus enabling the global electrification...

The goal of the “Advanced Network Analysis of Hydrogen Fuel Cell Automated Vehicles for Goods Delivery” (ATLAS) project is to examine the costs and energy system impacts of using hydrogen (H2) fuel cell electric vehicles (FCVs) for medium-duty goods delivery applications, with human drivers and some degree of automated operation in the future. Direct goods delivery to residences and commercial operations is an expanding transportation element that has been growing at approximately 9% per year in recent years, with an estimated $343 billion global industry value in 2020.

This study examined driver acceptance and performance of hydrogen fuel cell electric vehicles as tested in real-world conditions over a two-year period. The study sample was a volunteer group of “n = 54” drivers who drove the vehicle for a month-long trial period. Each driver took ‘before’ and ‘after’ surveys regarding their driving experience. Drivers drove an average of 1400 miles per month, and either witnessed and/or performed vehicle refueling 3–10 times during their test period. Key findings from the study include that: 1) 80% of study participant drivers found that the fuel cell...
