Daimler Buses introduces Citaro hybrid bus; available on diesel and gas models; separate 48V network

Green Car Congress

The hybrid powertrain is optionally available for a large number of model variants of the best-selling urban bus, even for the natural-gas-engined Citaro NGT. The electric power generated by recuperation is stored in a bank of supercapacitors. These electricity storage units are characterized by a high power density.

Toshiba H2One hydrogen-based autonomous energy supply system now providing power to a Kyushu Resort Hotel; hydrogen storage alloy

Green Car Congress

H2One integrates a photovoltaic power generation system with batteries for storing output power; a hydrogen-producing water electrolysis unit; solid state hydrogen storage—a MmNi 5 (Mischmetal-nickel) alloy); and a hydrogen fuel cell unit. MmNi 5 alloys belong to a class known as AB 5 -type alloys. Click to enlarge.

Two studies exploring battery costs for hybrids and plug-ins: LEESS, PHEV20, and PHEV40

Green Car Congress

For PHEV20 batteries, TIAX found significant overlap in battery costs among five cathode classes, with wider variation within each chemistry based on the electrode design than between chemistries. For PHEV20, the program focused on both commercially available and emerging cathode materials aimed for use in a 20-mile PHEV battery pack.

Study Finds Bioelectricity Better Option Than Liquid Biofuels for Transportation Output and GHG Emissions

Green Car Congress

In the assessment, the team used The Energy and Resources Group Biofuel Analysis Meta-Model (EBAMM) to consider scenarios covering a range of feedstocks and energy conversion technologies including corn and cellulosic ethanol, and four different vehicle classes: small- and mid-size cars and small and full-size SUVs.

Clearing the roadblocks to electrification of heavy-duty trucks

Charged EVs

Upfront costs are steadily approaching parity with legacy vehicles, purchase incentives are available, and new programs at the levels of federal (IRA, BIL), state (California’s ACT and ACF) and local (city zero-emission zones) government are driving (some would say “coercing”) companies to move forward quickly. It’s called Electric Island.

New Electrostatic Nanocapacitors Offer High Power and High Energy Density

Green Car Congress

But there are many small scale applications, [including] better electrical storage systems for cellphones or laptops.” Gary Rubloff. The fabrication strategy makes use of AAO nanopore templates in combination with metal–insulator–metal (MIM) structures deposited in the nanopores by ALD.
