    Mike Roeth Jan 24, 2020 for ACTNews - No Doubt About It: The Future Is Electric

    For a time, trucking will be a multi-fuel industry, but in the end electricity will be the dominant power source for commercial vehicles . . as we move to a future zero-emission freight world, electric powered vehicles . . will dominate the marketplace. This will occur because of the efficiency of battery electric powertrains for transporting freight when viewed from well-to-wheel.

    Today the current technology diesel and natural gas engines can cover the entire variety of freight payloads and daily ranges when using renewable versions of the fuels. At this point, commercial battery electric vehicles are more suited to shorter regional and urban ranges with regenerative braking and with payloads somewhat below maximums due to the battery weight.

    Overall, the volume of production-level alternative fuel vehicles is very limited today. While many manufacturers are ramping up initial production lines for the 2020-2025 timeframe, significant production volumes are likely not feasible until the latter half of the decade, after designs have been through a few iterations based on field experience and market demand has increased substantially.

      Matthew Mercure for NGTNews June 25, 2020 - OCTA Board Approves Plan to Convert Fleet to Zero-Emission Technology

      The Orange County Transportation Authority (OCTA) board has approved a draft plan outlining how the agency will convert the OC Bus fleet to 100% zero-emission technology by 2040. OCTA has already gradually transitioned its fleet over the years, from diesel-burning buses to clean-burning renewable compressed natural gas (CNG) buses with near-zero-emission engines. The state has set a requirement to transition to complete zero-emission transit within the next 20 years.

      Testing both hydrogen fuel-cell and plug-in battery-electric buses will allow OCTA to collect valuable data and to determine which technology – or the best mix of technologies – to pursue moving forward. OCTA operates more than 500 buses in the regular OC Bus system across Orange County. For now, most of those buses run on CNG, but OCTA is working toward the goal of producing zero emissions.

        Dani Teumou for ACTNews August 6, 2020 - What Can the Evolution of NGVs Teach Us about the Future of Electric Trucks?

        On June 27, the California Air Resources Board approved the Advanced Clean Truck (ACT) rule, which will require manufacturers of medium- and heavy-duty vehicles (MHDVs) to sell zero emission trucks in the state in steadily increasing percentages beginning in 2024. Many medium- and heavy-duty fleets operating today have already made one major transition, from gasoline and diesel to cleaner-burning natural gas.

        Talking with the fleets that made this transition, moving from diesel and gasoline to natural gas vehicles required significantly more investment, driver and mechanic education, trial-and-error and more collaboration alongside vehicle engineers and original equipment manufacturers (OEMs) than anyone could have anticipated. Establishing today’s robust NGV marketplace, where essentially any vehicle in any configuration a fleet might require is available, was a long road. It wasn’t until just six to nine years ago that the industry really began to deliver a consistent, technologically and environmentally superior natural gas product.

        To meet the operational demands of today’s diverse fleets, electric vehicles will have to undergo a similar evolution. Although the exact timeline is unknown, it will take years (possibly a decade or more) to get this next generation of advanced vehicle technology just right for every fleet’s needs. It has been 30 years since California first mandated sales of zero emission automobiles for the passenger vehicle market, and light-duty EVs are still struggling to secure widespread commercial acceptance.
