Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. The low cost of porous melamine means that the material could be deployed widely. —Mao et al.

billion in health costs, resulting in an estimated 1,000 premature deaths each year. Improved battery technology plus access to cheap renewable electricity open the possibility of battery-electric rail. The social cost of carbon emissions starts at US$125?t t –1 in 2021 and increases to US$226?t t –1 by 2040. Popovich et al.

Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

A team led by researchers from Sandia National Laboratories has shown that molybdenum disulfide (MoS 2 ), exfoliated with lithiation intercalation to change its physical structure, performs as well as the best state-of-the-art catalysts for the hydrogen evolution reaction (HER) but at a significantly lower cost. —Stan Chou.

PNNL, OSU team develops a durable, inexpensive molybdenum-phosphide catalyst for efficient conversion of wastewater & seawater into hydrogen

Green Car Congress

Like seawater, the MoP catalyst material is widely available, and therefore, cheap. This integrated design increases productivity and lowers equipment costs. But with the high cost of platinum, the team needed a catalyst that could lower production costs to around two dollars per kilogram of hydrogen.

Momentum Technologies licenses ORNL MSX process to recover metals from spent Li-ion batteries

Green Car Congress

a Texas-based materials science company that is focused on extracting critical metals from electronic waste, has licensed an Oak Ridge National Laboratory (ORNL) process for recovering cobalt and other metals from spent lithium-ion batteries. MSX is a closed-loop process; it is cheap, modular, energy efficient and produces nearly zero waste.
