The major compound groups in FPBO are water (20–25 wt %), carboxylic acids (∼ 5 wt %), aldehydes, ketones, and furfurals (25 wt %), sugar-like material (30–35 wt %), and lignin-derived compounds (20 wt %). In HTL, wet feedstock is liquefied in a hot (250–374 °C) and pressurized (4–22 MPa) water environment into biocrude oil.

With the next-generation fuel cell system being co-developed with General Motors (GM), Honda will aim to more than double the durability and reduce the cost to one-third, in comparison to the fuel cell system installed in the 2019 Honda Clarity Fuel Cell. Initiatives toward the establishment of hydrogen ecosystems.

A key role is played by dual layers of high density polyethylene adding up to 4 mm thickness, as a water diffusion barrier. This is measured by “water activity,” a quantity similar to relative humidity. By comparison, some direct air capture and carbon dioxide gas sequestration strategies cost US$600 per tonne.)

Researchers from Purdue University and École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are proposing a new integrated process involving the co-production of hydrogen and electricity from solar thermal energy—a concept they label “hydricity”.

Promising avenues include weight savings and extension of the cruising range in comparison with battery-powered solutions; fuel cell concepts may represent an attractive option for long-distance hauling, which requires heavy loads and large cruising ranges. As a result, the charge air coolers used must be resistant to ionized water.

This work provides proof-of-concept for a new approach to overcoming one of the key remaining challenges, which is the lack of highly active catalyst materials to speed up the critical reactions. Green hydrogen is a carbon-free method that uses an electrolyzer to split water into hydrogen and oxygen gas.

Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. It may not sound super significant, but it was quite a path to get here.
