The race to decarbonize the U.S. transportation sector is on. With a historic federal aim in place to remove almost 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 methods of the long run.
The workshop, titled “Envisioning Tomorrow’s Sustainable Mobility Programs,” requested consultants from throughout the nation to determine the applied sciences, traits, and options that may contribute most to creating sustainable mobility methods: in different phrases, essentially the most energy-efficient, reasonably priced, equitable, and secure methods of transferring individuals and items.
“The way forward for sustainable vitality methods will should be holistic — contemplating expertise parts and methods, human habits, and our total mobility transitions,” mentioned Jacob Ward, who oversees the Vitality Environment friendly Mobility Programs program throughout the U.S. Division of Vitality (DOE) and delivered the workshop’s keynote deal with. “We’re not simply aiming to create a sustainable end-state a long time 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 businesses; and NREL and college researchers. These members introduced challenges, alternatives, and options to the desk throughout six main matters to assist chart a course for the following section of mobility methods analysis.
Learn concerning the six cross-cutting matters beneath.
Learn key takeaways from the Envisioning Tomorrow’s Sustainable Mobility Programs workshop.
Understanding Advanced Journey Behaviors
A key part of future mobility methods can be sustainable modes of journey, from electrical and autonomous automobiles to e-bikes, e-scooters, and public transit. Nevertheless, sustainable transportation must be a minimum of as handy and versatile as energy-intensive modes, like driving a personal automobile, to create significant impression.
Workshop members concluded that options on this space must be targeted on enhancing the comfort of energy-efficient modes of journey. Excessive-quality mild rail, bus speedy transit, carpooling, incorporating e-bikes into transit, and nonmotorized modes of journey are all viable parts of lower-emission journey choices, however expertise options are wanted to deal with the ache factors of those methods.
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, resembling “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 day by 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 could 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, embrace enhancing our infrastructure to make nonmotorized types of journey viable. Longer-term options might require visionary desirous about land use and constructed environments in the US. That may embrace clustering developments nearer to the locations individuals stay and rezoning for mixed-use improvement.
Novel Transit Options To Profit Underserved Communities
Improved transit providers have results that span communities, together with higher high quality of life and price financial savings for individuals who are transit-dependent, in addition to important vitality and emissions reductions. However innovation on this space can be as a lot about institutional innovation — the flexibility to rapidly evolve the enterprise of transit — as it’s about progressive mobility applied sciences.
“There seems to be a chance to reimagine transit in our society,” Younger mentioned. “Modernized transit methods 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 businesses face, which is declining ridership. They could even appeal to a brand new technology to public transit.
“However,” Younger mentioned, “public transit businesses have to leverage rising applied sciences, in addition to deployment steering, to get there.”

For future mobility methods 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 find out how to combine multimodal journey inside transit methods; assessing novel modes with respect to expertise, coverage, enterprise, and business maturity; and serving to to plan and deploy transit providers for rural and deprived communities.
Rising Traits 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 lowering carbon emissions. But the boundaries to decarbonizing freight are important, from negotiating complicated logistics to creating buy-in for clear applied sciences.
That mentioned, outdated paradigms are starting to vary. Alicia Birky, NREL’s lead analyst for rising freight applied sciences, famous that conversations about decarbonizing freight have shifted in recent times 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 expertise and infrastructure to assist decarbonized freight operations. Researchers ought to work to determine how new knowledge streams, like knowledge from digital logging units mandated for all cargo carriers, can assist allow higher insights and expertise options.
Fairness concerns, too, can’t be missed. These issues embrace 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 employees have entry to freight-related jobs.
Slicing-Edge Operations Ideas
Automated automobiles have the potential to create important vitality financial savings, particularly when electrified. However as automobiles change into smarter, “clever” infrastructure can also be wanted — resembling visitors indicators which are geared up with sensors and cameras and thus able to regulating visitors flows. These sorts of applied sciences can assist automobiles and weak street customers journey safely, use much less vitality, and cut back congestion. They are going to be particularly essential as rising numbers of autonomous automobiles hit the roads.

“Infrastructure must change into a minimum of as clever because the automobiles that work together with it,” mentioned NREL’s Stan Younger, a complicated transportation and concrete scientist who led the dialogue on the subject. “It’s the first means to increase advantages to weak street customers like pedestrians, cyclists, and automobiles that aren’t related or automated.”
Larger data-sharing can be vital to assist the deployment of those rising applied sciences, which embrace superior visitors management at intersections, automated valet parking service built-in with automated electrical charging, and different strategies of connecting automobiles to their environments. Nevertheless, deploying these options in the true world could be difficult resulting from workforce coaching points and funding — to not point out the breakneck tempo of expertise improvement, which may trigger sensors to change into outdated quickly after they’re put in.
In response to those challenges, members known as on infrastructure owner-operators to broadly share the info gathered and classes discovered from early deployments — even deployments that won’t absolutely succeed of their targets. Urgent for open knowledge protocols and frameworks, they emphasised, will permit 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 contemplate find out how to assist clever infrastructure over the approaching years and a long time and assist safety-critical functions resembling safety-affirmative signaling. Methods ought to embrace workforce coaching for brand spanking new methods, securing sustained funding, decreasing total 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 measurement, speedy development, and important worker base trigger them to basically perform as small cities. They usually serve extra than simply passengers: They’re additionally chargeable for guaranteeing workers, rideshare drivers, and transit and cargo operators can navigate their services. Due to their measurement and the complexity of their wants, the options rising to maneuver individuals to and thru airports might have important 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 “individuals movers.” Now, members famous, airports might be properly served by decision-making assist to find out which floor mobility applied sciences to undertake and find out how to deploy them. As they appear to electrification and autonomous applied sciences to scale back their vitality use and emissions, members voiced robust assist for a nationwide consortium of airport representatives paired with skilled advisors that may assist to de-risk deployment and speed up innovation.

Duvall, who focuses on transportation behaviors, famous that floor mobility options hinge on a human aspect: particularly, whether or not individuals 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 services, they are going to want robust communication and information-sharing strategies to assist client adoption. Investing in these methods can be vital, as members agreed that any vitality and emissions reductions at airports might want to concurrently enhance buyer experiences, together with for passengers with lowered mobility.
Analysis and Actual-World Deployment
“There are a lot of individuals 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 rapidly, 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 instrument — an expanded model of a expertise readiness scale — should deal with not solely expertise maturity, but in addition the readiness of related insurance policies and industries. It might permit innovators to higher describe expertise maturity to native audiences. It might additionally assist to outline what “success” appears to be like like for rising applied sciences and make sure that the market — and the general public — is prepared for these options.
Contributors additionally known as for researchers, business companions, and expertise deployers to convene on impartial floor and share finest practices, threat mitigation methods, and deployment steering. Younger proposed creating areas the place communities and operators in search of 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 corporations and nationwide laboratories. Whereas peer-reviewed publications make sure that researchers’ conclusions are technically sound, they need to be accompanied by communications for the general public — together with one-page summaries, truth sheets, movies, and social media content material. These distilled communications can be utilized to make enterprise instances, educate communities, unfold consciousness of rising applied sciences, and level policymakers to actionable options.
