As of 2020, the greatest contributor to U.S. greenhouse gas emissions was the transportation sector, at 27 percent. Of that pollution total, 22.4 percent was generated by passenger cars and light-duty, medium-duty and heavy-duty trucks. The remaining 4.59 percent was attributable to aircraft, rail, ships, and other emitters. 

To avert global warming, the U.S. needs to transition from the ubiquitous fossil-fuel-burning internal combustion engine to electric and/or other earth-friendly propulsion sources. The vision of zero-emission vehicles is absolute nirvana, a clear pathway to clean skies, improved health and a bright future for our planet. But there is an inconvenient reality: The U.S. generates 60.8 percent of its electricity by burning fossil fuels. Much like our air conditioners, refrigerators, televisions, and computers, EVs can only be as clean as the electricity powering them.

During 2019, California experienced 25,281 electric power outages, a 23 percent increase over 2018. Those outages victimized 28.4 million customers, a 50 percent increase over the 19 million Californians affected in 2018. Recently, electric grid operators’ groups such as the North American Electric Reliability Corp. (NERC) and the Midwest Independent System Operators (MISO) forecasted an increased frequency of blackouts and brownouts during the summer of 2022.

By 2030, 8.7 million EV passenger vehicles and 10.4 million last-mile delivery trucks are expected to occupy U.S. roadways. Assuming annual passenger car usage rates of 13,474, and 12,435 miles for last-mile delivery trucks, at an average of 3.46 miles per kW, that will consume as much electricity as 2.7 million single-family U.S. homes.  

Legislation like New York’s Electric Building Act guarantees increased electricity consumption. Also, ever increasing fossil-fuel prices (required to make demand electricity) will increase production costs that will ultimately trickle down to consumers. Boston Consulting Group predicts that increased EV demand will require utilities to invest $1,700 to $5,800 per electric vehicle in grid upgrades through 2030. That $178.7 billion investment will assuredly increase consumer prices.  

The Need for Practicality

For EVs to become ubiquitous, numerous hurdles preventing the masses from adopting EVs as their sole source of transportation must be overcome.

Charging at home is both convenient and cost effective for the 67 percent of Americans who live in single family homes. But will multi-car families be willing to interrupt their evenings to plug in a second EV or will they incur the cost of adding another Level-2 charger, or the exorbitant cost of acquiring and installing a Level-3 charger? Moreover, in an emergency, a person’s ability to respond will be limited by the number of EV chargers available along the route, their charging speed, and functionality.

Freedom to Travel Coast-to-Coast

Without millions of fast, reliable, and safe EV chargers throughout the U.S., many consumers will resist EV adoption. For example, in 2021 the California Energy Commission’s Electric Vehicle Charging Infrastructure Assessment warned that the state will need 1.2 million EV chargers by 2030.

The U.S. has over 1.1 million fuel nozzles and a fill-up takes about three minutes. When contrasted against a 150kW DC fast-charger, three minutes provides less than 30 miles of range. Subsequently, to satisfy the motoring public’s needs and to provide peace of mind, the U.S. will require many millions of ultra-fast-output public EV chargers.

True Zero-Emissions Vehicles

In an effort to provide EV drivers with blackout and brownout immunity, offset power plant CO2 emissions, and to provide ultra-fast charging speeds, I created the Wind & Solar Tower (WST). This charger, the only one in the world powered by both wind and sun, is capable of simultaneously charging six EVs at Level-4 DC 380kW 1000-volt speeds that provide about 328 miles of range in just fifteen minutes. With up to a megawatt of battery storage capacity, each tower provides 797,900 miles of pollution-free driving per year and offsets 340.91 tons of atmospheric CO2 emissions.

My wind-and-sun-powered generating plant makes electricity on site for less than half the cost of utility-supplied power. Factoring in certain government programs, kWh costs can be reduced to nearly zero.

Reliability and ease of service are paramount with the WST. My team’s vast engineering and automotive capabilities means self-diagnostic capabilities and a 40-year service life. The WST features the lowest acquisition cost per EV charging outlet and generates – at virtually zero cost – 11,520 20kW charges with 100-percent-renewable energy that supplants electric grid load, which in turn reduce CO2 emissions and averts global warming.

ford-c-max-energi-solar-roofThe thought of vehicle-integrated solar cells taking an active role in powering an electric car remains a tantalizing prospect. In fact, the use of solar panels on the roof of a vehicle is not a new idea. It’s been shown that ultra-lightweight solar race cars with solar-packed body shells can actually drive exclusively on the power of the sun. In real life, though, this doesn’t work with production cars weighing thousands of pounds that need to carry varying numbers of passengers and weight, provide the acceleration needed for safe motoring, and in general perform all the functions required of a modern car.

Disappointing to some, car-mounted solar panels typically generate just enough electricity to operate a fan to keep the interior of a parked car cool on a hot day, falling fall far short of providing the kind of energy needed for drive motors. Lowering cabin temperatures in a parked EV does serve a purpose since less energy is needed to cool the passenger space during the early part of a drive. That means less of a drain on batteries needed to power an electric vehicle. In this case, every little bit helps.

There are other answers and solar charging does take different forms. Plenty of EV owners offset their car’s use of electricity through large solar panels on their homes. Many public charging stations also make use of solar arrays to provide at least part of the power needed for charging electric vehicles. These have been the most logical examples of solar charging to date. Still, efforts toward creating the true solar car continue.

The latest example comes from Ford. Working in a collaborative project with long-time solar technology partner SunPower and Georgia Institute of Technology, Ford’s C-MAX Solar Energi Concept embraces an innovative approach that could potentially deliver the same amount of electrical power as plugging a C-MAX Energi PHEV into the electrical grid. The goal is no less than creating a logical stepping stone toward making a solar-powered hybrid feasible for daily use.

Ford’s C-MAX Solar Energi Concept benefits from amplifying the sunlight that enables the car’s already-efficient SunPower solar cells to create electricity. A huge jump in solar energy conversion is accomplished with a special solar concentrator lens that directs intense solar rays to the solar panels on the vehicle's roof. The off-vehicle solar concentrator uses a special Fresnel lens of the type originally invented for use in lighthouses, boosting the impact of sunlight by a factor of eight. Similar in concept to a magnifying glass, the patent-pending system tracks the sun as it moves from east to west.

With the aid of the concentrator, the system can collect enough energy from the sun each day to equal a four-hour battery charge for the C-MAX Energi, about 8 kilowatt-hours. Ford says this is sufficient to deliver the same performance as a conventional C-MAX Energi plugged into the electrical grid.  The Ford C-MAX Solar Energi Concept would also have the same total range as a conventional C-MAX Energi of up to 620 miles, including up to 21 electric-only miles. Since the sun isn't always shining, there is still a charge port so this solar Energi variant t can be charged conventionally from the grid.

ford-c-max-solar-carport

The special solar concentrator carport used with the C-MAX Solar Energi is conceptualized in a way that maximizes capturing solar energy as the sun moves throughout the day. This requires an east-west carport orientation and also the ability for the car to autonomously move forward and backward beneath the canopy during daylight hours, thus enabling its solar cells to make the most of sunlight directed by the concentrator. As Consumer Reports posits, not only does this require buying into the concept of an unattended car moving all by itself during the day, but also the potential liability issues that could come with it.

Ford studies suggest that the sun could power up to 75 percent of all trips made by an average driver in a solar hybrid vehicle. Solar charging could be especially valuable in places where the electric grid is underdeveloped, unreliable, or expensive to use. In addition, use of a C-MAX Solar Energi could reduce yearly CO2 and other greenhouse gas emissions from the average U.S. car owner by as much as four metric tons – the equivalent of what a U.S. home produces in four months. If all light-duty vehicles in the United States were to adopt Ford C-MAX Solar Energi Concept technology, annual greenhouse gas emissions could be reduced by approximately 1 billion metric tons.

Next up: Ford and Georgia Tech will be testing the concept under real-world conditions. The outcome of those tests will help determine if the concept is feasible as a production vehicle.
