Green hydrogen is a carbon-free method that uses an electrolyzer to split water into hydrogen and oxygen gas. The low efficiency of available electrolyzers means that most of the energy in the water-splitting step is wasted as heat, rather than being captured in the hydrogen.
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.

Algenol Biofuels’ Direct to Ethanol technology is based on an intracellular photosynthetic process in cyanobacteria (blue-green algae) that produces ethanol that is excreted through the cell walls, collected from closed photobioreactors as a dilute ethanol-in-water solution, and purified to fuel grade ethanol. Algenol algae.
This separation process involves low energy and reagent requirements and does not contribute to waste generation. Reaction temperature is controlled via a water bath, recirculation is carried out through a gear pump, and crystallization of metal salts occurs on the nucleation scaffold. —Stetson et al. atmospheres.

Despite this, research on the environmental and health impacts of tire wear has been neglected in comparison to the research and innovations dedicated to tackling fuel emissions. Tire wear particles pollute the environment, the air we breathe, the water run-off from roads and has compounding effects on waterways and agriculture.
In addition to greenhouse gas emissions, the report also assesses a number of other environmental impact categories, ranging from resource use, including cumulative energy consumption, mineral and metal resource depletion and water scarcity, to airborne pollutant emissions (like particulates and nitrogen oxides), and human- and eco-toxicity.
An international study of 10 global cities found that a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the greenhouse gas emissions (GHGs) attributable to cities.

The high temperature exhaust also facilitates the use of otherwise wasted thermal energy for heating of the vehicle interior, thus increasing overall system efficiency. There is no liquid water in a HTPEM MEA and therefore there is no need for a compressor. Other benefits of the Serenergy HTPEM technology include: No humidifier.
