The race to decarbonize the U.S. transportation sector is on. With a historic federal objective in place to eradicate practically all greenhouse fuel emissions from the sector by 2050, curiosity in clear transportation applied sciences has skyrocketed. However the nation nonetheless faces a urgent query: Which energy-efficient mobility methods will get us to the end line in time?
That query was the main target of a two-day workshop hosted by the Nationwide Renewable Vitality Laboratory (NREL), the place thought leaders from business, authorities, and academia mentioned the challenges — and alternatives — that must be prioritized to create the sustainable transportation techniques of the long run.
The workshop, titled “Envisioning Tomorrow’s Sustainable Mobility Methods,” requested specialists from throughout the nation to determine the applied sciences, developments, and options that may contribute most to creating sustainable mobility techniques: in different phrases, probably the most energy-efficient, reasonably priced, equitable, and secure methods of transferring folks and items.
“The way forward for sustainable vitality techniques will have to be holistic — contemplating know-how elements and techniques, human habits, and our general mobility transitions,” mentioned Jacob Ward, who oversees the Vitality Environment friendly Mobility Methods program throughout the U.S. Division of Vitality (DOE) and delivered the workshop’s keynote handle. “We’re not simply aiming to create a sustainable end-state many years from now. We’re dedicated to getting there sustainably, too.”
The workshop convened a number of the greatest gamers within the transportation area, together with representatives from DOE and the U.S. Division of Transportation; cities, airports, and transit companies; and NREL and college researchers. These members introduced challenges, alternatives, and options to the desk throughout six main subjects to assist chart a course for the following part of mobility techniques analysis.
Learn concerning the six cross-cutting subjects beneath.
Learn key takeaways from the Envisioning Tomorrow’s Sustainable Mobility Methods workshop.
Understanding Complicated Journey Behaviors
A key element of future mobility techniques might be sustainable modes of journey, from electrical and autonomous automobiles to e-bikes, e-scooters, and public transit. Nonetheless, sustainable transportation must be a minimum of as handy and versatile as energy-intensive modes, like driving a non-public automobile, to create significant impression.
Workshop members concluded that options on this space must be targeted on bettering the comfort of energy-efficient modes of journey. Excessive-quality gentle rail, bus speedy transit, carpooling, incorporating e-bikes into transit, and nonmotorized modes of journey are all viable elements of lower-emission journey choices, however know-how options are wanted to deal with the ache factors of those techniques.
As an illustration, higher scheduling can enhance public transit effectivity and make it simpler for vacationers to depart and arrive on time. Journey will also be made extra seamless with apps that combine on-demand journey choices, like calling a rideshare car or renting an e-scooter to cowl the primary and final mile of journey. Contributors additionally mentioned the significance of non-monetary incentives in selling sustainable journey, corresponding to “time buffers”: flexibility in begin or finish occasions for workers who use public transit to get to work.
Venu Garikapati, a researcher who leads NREL’s transportation modeling and metrics group and who facilitated dialogue on this matter, emphasised that our journey behaviors are attuned to our environments.

“Nearly all of each day journeys within the U.S. are lower than three miles,” Garikapati mentioned, referencing a 2021 examine from the Bureau of Transportation Statistics. “These sorts of automobile journeys will be changed with bikes, e-bikes, on-demand and micro-transit, and different energy-efficient types of journey — however provided that the infrastructure permits it.”
Quick-term options, Garikapati mentioned, embody bettering our infrastructure to make nonmotorized types of journey viable. Longer-term options might require visionary desirous about land use and constructed environments in the USA. Which may embody clustering developments nearer to the locations folks reside and rezoning for mixed-use growth.
Novel Transit Options To Profit Underserved Communities
Improved transit providers have results that span communities, together with higher high quality of life and value financial savings for many who are transit-dependent, in addition to vital vitality and emissions reductions. However innovation on this space might be as a lot about institutional innovation — the power to shortly evolve the enterprise of transit — as it’s about revolutionary mobility applied sciences.
“There seems to be a chance to reimagine transit in our society,” Younger mentioned. “Modernized transit techniques could possibly compete with the modes persons are used to, like driving personal automobiles. They could be capable of mitigate the pressing concern all transit companies face, which is declining ridership. They could even appeal to a brand new technology to public transit.
“However,” Younger mentioned, “public transit companies have to leverage rising applied sciences, in addition to deployment steerage, to get there.”

For future mobility techniques to serve marginalized communities, it’s crucial for researchers to assist fill in these analysis gaps. They’ll start by forecasting future demand for on-demand transit; measuring transit effectiveness with instruments such because the Mobility Vitality Productiveness metric; demonstrating combine multimodal journey inside transit techniques; assessing novel modes with respect to know-how, coverage, enterprise, and business maturity; and serving to to plan and deploy transit providers for rural and deprived communities.
Rising Developments in Freight
Freight — the motion of products across the nation and world — creates an outsize share of transportation emissions, largely as a result of the vans, trains, boats, and planes that transfer items are the world’s most fossil-fuel-dependent automobiles. Decarbonizing freight motion might, in flip, create an outsize impression on decreasing carbon emissions. But the boundaries to decarbonizing freight are vital, from negotiating complicated logistics to creating buy-in for clear applied sciences.
That mentioned, previous paradigms are starting to alter. Alicia Birky, NREL’s lead analyst for rising freight applied sciences, famous that conversations about decarbonizing freight have shifted lately from a query of “if” to “when.”

“Attitudes towards battery-electric freight have shifted over the previous few years from resistance to a rising acceptance that electrification is the long run. And hydrogen applied sciences are additionally gaining traction,” Birky mentioned. “However new applied sciences and operational modifications carry dangers, particularly for smaller operators. We have now an actual alternative to assist de-risk them.”
Options on this area, members emphasised, ought to give attention to addressing a urgent concern amongst operators: a perceived hole between federal clear vitality objectives and the readiness of know-how and infrastructure to help decarbonized freight operations. Researchers ought to work to determine how new information streams, like information from digital logging gadgets mandated for all cargo carriers, may help allow higher insights and know-how options.
Fairness concerns, too, can’t be ignored. These considerations embody ensuring that rural and deprived communities have equitable entry to items, that freight operations don’t disproportionately have an effect on deprived neighborhoods, and that staff have entry to freight-related jobs.
Chopping-Edge Operations Ideas
Automated automobiles have the potential to create vital vitality financial savings, particularly when electrified. However as automobiles turn into smarter, “clever” infrastructure can be wanted — corresponding to site visitors indicators which might be outfitted with sensors and cameras and thus able to regulating site visitors flows. These sorts of applied sciences may help automobiles and susceptible highway customers journey safely, use much less vitality, and scale back congestion. They are going to be particularly essential as rising numbers of autonomous automobiles hit the roads.

“Infrastructure must turn into a minimum of as clever because the automobiles that work together with it,” mentioned NREL’s Stan Younger, a sophisticated transportation and concrete scientist who led the dialogue on the subject. “It’s the first means to increase advantages to susceptible highway customers like pedestrians, cyclists, and automobiles that aren’t linked or automated.”
Better data-sharing might be crucial to help the deployment of those rising applied sciences, which embody superior site visitors management at intersections, automated valet parking service built-in with automated electrical charging, and different strategies of connecting automobiles to their environments. Nonetheless, deploying these options in the actual world will be difficult on account of workforce coaching points and funding — to not point out the breakneck tempo of know-how growth, which may trigger sensors to turn into outdated quickly after they’re put in.
In response to those challenges, members known as on infrastructure owner-operators to extensively share the info gathered and classes discovered from early deployments — even deployments that will not totally succeed of their targets. Urgent for open information protocols and frameworks, they emphasised, will enable others to construct upon these deployments, in the end serving to to evolve towards nationwide requirements for clever infrastructure.
Within the close to time period, members agreed that options ought to give attention to “low-hanging fruit”: functions that may be carried out in current controller {hardware} and software program. Lengthy-term options ought to take into account help clever infrastructure over the approaching years and many years and help safety-critical functions corresponding to safety-affirmative signaling. Methods ought to embody workforce coaching for brand spanking new techniques, securing sustained funding, decreasing general system prices, and establishing service agreements for third-party upkeep and repairs.
Floor Mobility at Airports
Airports are on the forefront of innovation within the transportation sector. Their dimension, speedy progress, and vital worker base trigger them to primarily operate as small cities. They usually serve extra than simply passengers: They’re additionally chargeable for making certain workers, rideshare drivers, and transit and cargo operators can navigate their amenities. Due to their dimension and the complexity of their wants, the options rising to maneuver folks to and thru airports might have vital vitality advantages.
Many energy-saving rising applied sciences within the floor mobility area are both near deployment or already in use, from cell charging robots that may journey to parked electrical automobiles to autonomous, trackless “folks movers.” Now, members famous, airports might be effectively served by decision-making help to find out which floor mobility applied sciences to undertake and deploy them. As they appear to electrification and autonomous applied sciences to cut back their vitality use and emissions, members voiced robust help for a nationwide consortium of airport representatives paired with professional advisors that may assist to de-risk deployment and speed up innovation.

Duvall, who makes a speciality of transportation behaviors, famous that floor mobility options hinge on a human component: particularly, whether or not folks will undertake new options. Whereas many airports see autonomous car applied sciences as scalable and cost-effective options to transferring passengers and workers round their amenities, they may want robust communication and information-sharing strategies to help shopper adoption. Investing in these techniques might be crucial, as members agreed that any vitality and emissions reductions at airports might want to concurrently enhance buyer experiences, together with for passengers with diminished mobility.
Analysis and Actual-World Deployment
“There are numerous folks targeted on discovering and accelerating sustainable mobility options,” Younger mentioned. “We share an impatience to deploy improvements that may positively impression society.”
However, he continued, there’s a actual problem on this work: The market has little to no tolerance for perceived failure of rising applied sciences. Deploying too shortly, earlier than a product has been totally de-risked, can bitter perceptions of superior mobility options.

To stroll the wonderful line between speedy deployment and stringent de-risking, members known as for clear, shared language to quantify the maturity of unpolluted vitality improvements. This evaluation device — an expanded model of a know-how readiness scale — should handle not solely know-how maturity, but in addition the readiness of related insurance policies and industries. It will enable innovators to higher describe know-how maturity to native audiences. It might additionally assist to outline what “success” appears to be like like for rising applied sciences and be sure that the market — and the general public — is prepared for these options.
Contributors additionally known as for researchers, business companions, and know-how deployers to convene on impartial floor and share finest practices, threat mitigation methods, and deployment steerage. Younger proposed creating areas the place communities and operators looking for clear vitality developments can voice their challenges and be paired with researchers and business companions working towards options — often known as “reverse pitch” classes.
Furthermore, members known as for stronger, clearer communication from analysis companies and nationwide laboratories. Whereas peer-reviewed publications be sure that researchers’ conclusions are technically sound, they need to be accompanied by communications for the general public — together with one-page summaries, reality sheets, movies, and social media content material. These distilled communications can be utilized to make enterprise circumstances, educate communities, unfold consciousness of rising applied sciences, and level policymakers to actionable options.
