“Future-Proof” Technology Will Support Cities’ Sustainability and Resiliency Goals

Global Director of Resilience, AECOM

Part of a four-part series related to creating more sustainable, resilient transport infrastructure. Other articles in the series include 5 Lessons The World Can Learn From Dutch Resilience, and Full-Seats & Other Secrets to a More Sustainable Transport Future.


Let’s start with disclosure: The global infrastructure firm I work for, AECOM, is involved in supporting and developing several hyperloop efforts, so it’s not a stretch to say I come at this with the belief that this is a very cool technology. But, as the “climate and disaster guy,” I wondered how this idea fits into the work we have been doing to build infrastructure that is sustainable and resilient to the effects of climate change. The short answer is “yes” to both, but not in the way I originally thought. First, I will briefly define sustainability and resilience because they are both used pretty broadly these days.


I use sustainability in the environmental sense to mean that an infrastructure system or asset is one that doesn't create more problems for the environment than it solves. It can be low carbon and does not have unintended consequences we can’t address. Resilience is a little tougher to define clearly. In the climate and natural disaster world, we speak of the ability to absorb or quickly recover from acute shocks such as severe weather or chronic stresses like sea level rise. Sustainability is about treading lightly. Resilience is about getting back up when you’re knocked down.


One thing that is clear is that now is the time to think about resilience and sustainability. Communities and companies are focusing on these issues because they realize this is not a problem that can be ignored or avoided. In its annual Global Risk Report, the World Economic Forum places climate and disaster risks in the quadrant that reflects the highest probability and greatest impact.


The good news is that cities around the world are leaning forward on resilience. As part of efforts like the Rockefeller Foundation’s 100 Resilient Cities, UNISDR’s Making Cities Resilient campaign and broader city programs like C40 and the Compact of Mayors, there is a very strong focus on these issues at the municipal level. In its recently launched resilience strategy, Paris has committed to rethink how infrastructure is built and used to prepare for the challenges of the 21st Century. In New York City the recent update to their OneNYC resilience plan looks not just the core physical infrastructure but also looks at what that infrastructure does and how that affects the people in the city. And in Bangkok, the resilience strategy is based on three concepts: improving quality of life, reducing risk, and driving economic growth. They realize that these concepts are interdependent and critical to a thriving city. Across the developed and developing world, the signs are clear that we realize the need to be sustainable and resilient and great models of this are being created every day.


We often say walking and biking are the most sustainable forms of transportation. They are definitely low-emission and (even better) they are good for fitness. But I’m not sure I know anyone, except for a few crazy friends, who thinks a bicycle can replace the car or the airplane. I am writing this while sitting on a “high-speed” train from Washington, D.C. to New York City, traveling at more than 100 mph. That makes it faster than a car or bus, but slower than an airplane. This big train, Amtrak’s Acela Express, runs on electricity and it takes a lot of it to move it up and down the East Coast. As the grid gets greener each year it could, theoretically, be carbon neutral if the power generation were sustainable. My other choices for short distance, inter-city trips of under 300 miles are a car, bus, or airplane. Compared to those, based on current technology, this train is a greener choice.


But today’s high-speed trains have a physics problem called friction. The train experiences two types of friction: rolling resistance from the steel wheels on the rails, and air resistance or drag. Drag is, well, a drag, because it increases with speed and makes very high-speed trains less energy efficient. High-speed trains in France (TGV), Germany (ICE), and Japan (Shinkansen) spend a large portion of their energy overcoming this friction problem at speeds over 200 mph. Even the most streamlined shape does not put a big dent in the energy costs of air resistance. Ever wonder why planes fly at 35,000 feet? It’s because the air is much thinner and less resistant at that altitude and they need less fuel to overcome the drag.


Now we finally get to the hyperloop, which operates in tube with a low pressure environment. This means very limited drag, so you can go really fast without as much energy. It’s why we could fly astronauts to the moon at what would seem like ridiculous speeds on earth (nearly 25,000 mph) – because space is really big and is a near total vacuum with very little matter. The hyperloop won’t travel anywhere near that fast, but it could travel at speeds approaching 600 mph. So in terms of sustainability, hyperloop is like an electric car that can fly in space, but is restricted to where the tube is built.


But wait, I haven’t gotten to resilience yet. Resilience is about how we adapt to shocks and stresses so we can absorb or quickly recover from those disruptions. Hyperloop has two key resilience attributes. First, it’s new and because it’s built from scratch it can be designed to adapt to the changes we know are coming. Much of our existing transportation infrastructure is old and it’s often hard to retrofit older systems to be resilient to changes that were not known or anticipated when it was designed. The other resilient attribute of this new technology is that it provides additional capacity and another system. In a disaster, some systems will work and others will fail for reasons we can’t always predict. Disasters are often, by their very nature, unpredictable. Having more options is good for resilience. While it is possible that this system could be compromised like any other mode of transportation, more choices are better.


When I started to think about hyperloop, I assumed that there would be some key aspect of the technology that would drive sustainability and resilience but, in the case of the hyperloop, you have to look at the big picture to see the multiple factors that contribute to its resilience and compare this to the other choices available. Yes, sustainability is a function of energy sources and efficiency, but it also necessary to look at the “future-proofing” efficiency and effectiveness of the system -- how it will hold up over time and integrate into both legacy and future transportation networks.


I don’t think governments and private organizations are going to invest in a system like the hyperloop solely because of its sustainability or resilience attributes. If you can deploy a safe and cost-effective ground-based transport system that travels at airline speeds, I think it’s safe to say you will have a market. However, as cities around the word race to adopt sustainability and resilience standards, it will be a major factor in how they consider their future infrastructure investments.

    We aren't just building a hyperloop; we're building a network of public and private partners to scale an integrated supply chain ecosystem. Our business model is based on partnerships that create local jobs and opportunities for those who choose to invest in this technology. We are working at the highest level of governments around the globe to put in place commercial agreements to make hyperloop a reality.

  • Q. What is hyperloop?

    Hyperloop is a new mode of transportation designed to eliminate the barriers of distance and time for both people and freight. It can travel at speeds approaching 700mph, connecting cities like metro stops - and it has zero direct emissions. The journeys can be booked on demand so there’s no wait time or delays.

  • Q. How does hyperloop work?

    With hyperloop, vehicles, called pods, accelerate gradually via electric propulsion through a low-pressure tube. The pod floats along the track using magnetic levitation and glides at airline speeds for long distances due to ultra-low aerodynamic drag.

  • Q. Has hyperloop technology been proven?

    On May 12th, 2017, we made history two minutes after midnight when we successfully launched our vehicle using electromagnetic propulsion and levitation under near-vacuum conditions at our full-scale test site in the Nevada Desert. We've since run hundreds of tests, acquiring validated knowledge that only comes from real-world testing. For more info on DevLoop, our 500 m test track, visit our progress page.

  • Q. How fast can hyperloop go?

    We estimate that the top speed for a passenger vehicle or light cargo will be 670 miles per hour or 1080 kilometers per hour. That is about 3 times faster than high-speed rail and 10-15 times faster than traditional rail. The average speed vehicles travel will vary based on the route and customer requirements.

  • Q. Why keep the tube at low-pressure and not at a perfect vacuum?

    A perfect vacuum would decrease the drag on the vehicle even more, but not significantly. We have already gotten rid of 99.9% of the air in the tube. Lower levels of vacuum than this are important if you are performing scientific experiments, but the cost would not be worthwhile.

  • Q. How is hyperloop different from high-speed trains?

    Hyperloop is an entirely new mode - think the best of trains, planes, and the metro. Hyperloop is on-demand, offering flexible travel schedules with no stops, no transfers, and no weather delays – all at speeds about 3 times faster than high-speed-rail and less cost. Hyperloop is highly efficient, with a smaller environmental impact than high-speed rail because the closed system can be tunneled below or elevated above ground, avoiding dangerous at-grade crossings. The VHO system is 100% electric and can reach higher speeds than high-speed rail for less energy due to our proprietary electric motor and low-drag environment.

  • Q. Is hyperloop safe?

    Fast, effortless journeys go hand-in-hand with journeys where everything works reliably without interference, and where all passengers feel comfortable and safe. The Virgin Hyperloop is designed to be inherently safer than other modes, with multiple redundancies in place. Our system operates autonomously in an enclosed tube and is not susceptible to weather delays, accidents from at-grade crossings, human error, or power outages. Our proprietary high-speed switching architecture eliminates unsafe track configurations and moving trackside parts, a failure point of traditional rail with mechanical switches.

  • Q. How do you plan to get hyperloop certified?

    As new mode, we have to prove our safety case to regulators and work with them to develop a regulatory framework, so passengers can ride the hyperloop in years not decades. We are encouraged by the support we are seeing at the local and federal level around the world to support hyperloop certification based on the fundamentals of safe operating that are already standard practice. In March 2019, the U.S. Secretary of Transportation, Elaine Chao, created the Non-Traditional and Emerging Transportation Technology (NETT) Council to explore the regulation and permitting of hyperloop technology to bring this new form of mass transportation to the United States. This Council is an important step forward in recognizing hyperloop is a new transportation mode and that we need to shift our mindset and acknowledge that this technology does not fit into a regulatory structure that is over 100 years old. The European Commission’s Directorate-General for Mobility and Transport (DGMOVE) has also been leading discussions with hyperloop companies to advance regulatory standards and, in India, the Principal Scientific Advisor (PSA), Prof. Vijayraghavan, has set up an independent committee called the Consultative Group on Future of Transportation (CGFT) to explore the regulatory path for hyperloop. For more, visit our regulatory progress pages.

  • Q. What will it feel like to ride hyperloop?

    While flying through a tube at more than 1000km/h might seem like a thrill ride, the truth is we are able to mitigate any uncomfortable acceleration forces within our controlled environment. The journey will be so smooth, you could sip a coffee the whole time without spilling a single drop. Normal acceleration and deceleration of 0.20 Gs will feel similar to a train. As a comparison, flooring a typical sedan gives between 0.4-0.5 Gs and commercial airplanes see 0.3-0.5Gs depending on the plane and load.

  • Q. What happens if there's a sudden breach in the tube?

    Pods will continue to travel safely to the next portal even with a large breach. Our response to a breach would be to intentionally repressurize the tube with small valves places along the route length while engaging pod brakes to safely bringing all pods to rest before it is deemed safe to continue to the next portal. A sustained leak could impact performance (speed) but would not pose a safety issue due to vehicle and system architectural design choices. This assessment is based in solid understanding and analysis of the complex vehicle load behaviors during such an event.

  • Q. Is hyperloop sustainable?

    Without a massive leap forward, pollution from the transportation industry is expected to almost double by 2050 - well above the carbon budget. By combining an ultra-efficient electric motor, magnetic levitation, and a low-drag environment, the VHO system can reach airline speeds for 5-10x less energy (depends on route length) and can go faster than high-speed rail using less energy. In regions like the Middle East, we could power the system completely by solar panels which cover the tube. As fighting against climate change becomes an existential issue for cities across the globe, hyperloop will create a new, shared, electric mobility model for helping to permanently reform an industry with some of the world’s highest carbon emissions.

  • Q. How much energy does hyperloop use?

    We are designing Virgin Hyperloop to be more efficient than other modes of transportation. Modern jetliners use up to 10 times the energy we use per passenger-mile over the entire journey. We can cruise at 500 miles per hour for less energy (per passenger) than an electric car doing 60 miles per hour. At peak speed, the VHO system consumes approximately 75 watt hours per passenger kilometer (Wh/pax-km). To put this in perspective, the fastest conventional maglev train travels at about half our speed and consumes 33% more energy.

  • Q. Where will hyperloop get its power?

    Our system is 100% electric with zero direct emissions. We're energy-agnostic. Our system can draw power from whichever energy sources are available along the route and support a transition to a renewable energy-powered future. In regions like the Middle East, we can completely power the system with solar panels which cover the tube.

  • Q. How much noise does hyperloop make?

    It’s similar those new electric vehicles that are so quiet they need to create noise to indicate movement. With hyperloop, we eliminate sources of mechanical noise, like wheels on track, and we actually have a sound barrier inherent in our tube design

  • Q. Can hyperloop be used for cargo?

    DP World Cargospeed is a global brand for hyperloop-enabled cargo systems operated by DP World and enabled by Virgin Hyperloop technology. These systems will deliver freight at the speed of flight and closer to the cost of trucking for fast, sustainable, and efficient delivery of palletized cargo.

  • Q. What type of cargo would a hyperloop system transport?

    The focus would be on high-priority, on-demand goods – fresh food, medical supplies, electronics, and more.

  • Q. How can hyperloop help transform logistics?

    With DP World Cargospeed, deliveries can be completed in hours versus days with greater reliability and fewer delays. It will expand freight transportation capacity by connecting with existing modes of road, rail, ports, and air transport, and will provide greater connectivity with manufacturing parks, economic zones, distribution centers, and regional urban centers. This can shrink inventory lead times, help reduce finished goods inventory, and cut required warehouse space and cost by 25%. DP World Cargospeed networks can also enable just-in-time, agile manufacturing practices.

  • Q. Will the first hyperloops be passenger or cargo systems?

    The Virgin Hyperloop is unique in that it doesn’t need to be passenger-only or cargo-only. We are designing a mixed-use system that fully utilizes system capacity while maximizing economic and social benefits. However, it is possible to run cargo commercial operations while certification and regulation are still ongoing for passenger use.

  • Q. When will hyperloop systems be ready for cargo and passengers?

    We are working with the most visionary governments around the world to make sure you can ride the hyperloop in years, not decades. Our goal is to have operational systems in the late 2020s. Our ability to meet that goal will depend on how fast the regulatory and statutory processes move.

  • Q. Where will the first hyperloop get built?

    We are working with visionary governments and partners around the world to make hyperloop a reality today. To learn more about our projects around the world, visit our progress page.

  • Q. How much will hyperloop cost to build and operate?

    Capital and operating costs will range widely based on the route. We recently released a study that showed our linear costs are 60-70% that of high-speed rail projects. In addition, we expect the operational costs to be significantly lower than existing forms of transportation.

  • Q. How much will hyperloop cost to ride?

    It’s simple – if it’s not affordable, people won't use it. We are looking to build something that will expand opportunities for the masses, so they can live in one city with their family and work in another. Currently, that kind of high-speed transport is not feasible for most people. The exact ticket price will vary for each route, but a recent study showed that riding a hyperloop in Missouri could cost less than the gas needed to drive.

  • Q. How are hyperloop routes selected?

    We are in the business of serving local needs, not the other way around. Public and private support is key. In some cases, we will respond to solicited bids with partners when we feel the technology matches the project’s objectives. In other cases, we will make an unsolicited bid for a project when we see that hyperloop could offer a unique solution to market needs.

  • Q. What is the process for getting a passenger route up and running?

    While the technology is different, the process for building a hyperloop is similar to that of building a highway, railway, or any other type of linear infrastructure. The first stage is project development. This phase includes feasibility studies, and then more detailed engineering reports and environmental impact studies. Once a project is approved to move forward, a consortium is formed to finance and deliver on the project.

  • Q. How much land does hyperloop require?

    Many infrastructure projects succeed or fail based on right-of-way issues. We are designing a system that requires only about half the right-of-way as high-speed rail and can more easily adapt to existing right-of-ways. At high speeds, the VHO system has a 4.5 times tighter turn radius compared to high-speed rail and can climb grades that are 6 times steeper, reducing the disturbance at crossings. Portals will be purposely integrated into and support existing communities and landscapes. Low noise levels will expand opportunities to build hyperloops closer to the city center.

  • Q. With the focus on connecting cities, how will hyperloop support rural communities?

    Hyperloop also holds enormous promise for rural communities. Virgin Hyperloop systems can be built below or above ground, which means no one’s farm needs to be cut in half. Our system enables rural areas to retain residents, who can now have more access to urban job centers, educational opportunities, and health care facilities. Additionally, hyperloop could enable freight distribution centers to be placed in rural areas, leading to job growth and industrial clusters. After a system is built, there is the opportunity to add additional on and off-ramps, supporting a greater number of people along the route.

  • Q. How will hyperloop projects be financed?

    Transportation infrastructure has traditionally relied on extensive government funding. This is because the benefits of clean, safe, and efficient transportation are enjoyed by the entire community, not just the user buying a ticket. However, most existing mass transportation modes are unprofitable and hindered by existing infrastructure built in the past century or by legacy systems. We want to change that and are focused on public-private partnerships. By developing a new mode of transportation from scratch, we're able to leverage technological developments that have occurred in the last century, especially the IT revolution. We're able to keep maintenance costs low, energy efficiency high, and transport tens of thousands of passengers per hour. This keeps margins and accessibility high, contributing to more financially attractive returns than if the corridor was served by existing modes. These benefits aren’t just hypothetical. While this is an exceptional case due to high demand, a third-party evaluation found that our Mumbai-Pune Hyperloop Project could be funded 100% by private capital. In the U.S. we see enormous potential to attract investment from the private sector, leveraging public investments. Involving government stakeholders as well as potential private investors early in the project development process is critical.
