According to Dr. Chris D'Couto, Neah Power's CEO and the featured guest in the interview below, a five kilowatt hour fuel cell running off a tank of liquid formic acid would be configured to trickle charge an electric vehicle's battery, allowing it, like the gasoline engine generator in the BMW i3 REx, to offer extended range capability. Unlike the i3 REx, the only tailpipe emission would be water vapor and CO2

Engine technology applied to existing PHEVs is derived from small conventional production gasoline engines, but highly specialized APUs for BEVxs may eventually spin off and evolve in completely different directions. Future BEVxs with highly specialized engine and fuel technologies could be optimized to drive cost, weight, size, and emissions down and make these specialized BEVx APUs suitable for more affordable and therefore more widespread application. Lotus Engineering and other automotive design firms have been developing hybrid-specific APUs and have several unique concepts under development already.

—ZEV ISOR

California’s new ZEV rule introduces the BEVx; ARB staff expects these vehicles to play a longer-term role than plug-in hybrids
On Friday 27 January, the California Air Resources Board (ARB) adopted the new Advanced Clean Cars (ACC) package that sets out the regulatory emissions and technology requirements for light-duty automobiles through model year 2025. (Earlier post.) The Zero Emission Vehicle (ZEV) regulation—one of the three main regulatory packages that constitute ACC—introduces a new regulatory vehicle category: the BEVx, or a battery-electric vehicle with a small “limp-home” range extending engine or APU (auxiliary power unit)—i.e., not a series-hybrid type vehicle such as the Chevrolet Volt equipped with a full-capability engine.

Under the ACC, ARB will award BEVx credits on the same basis as BEVs—i.e., on zero-emission miles (the simplified ZEV credit scheme under the ACC is a linear one based on those zero-emission miles). BEVx vehicles can provide up to 50% of the pure ZEV requirement for manufacturers, and so they may emerge as a significant vehicle type.

In the Initial Statement of Reasons (ISOR) published prior to the Board meeting, ARB staff noted that “some manufacturers” proposed this new class of advanced vehicles for separate treatment as part of the ZEV program. (During the public hearing on the ACC rule package, comments from ARB staff and the Board indicated that BMW was particularly interested in this classification.)
