Argonne-led team develops new low-cost cobalt-based catalyst for PEM electrolysis

Green Car Congress

A multi-institutional team led by the US Department of Energy’s (DOE) Argonne National Laboratory (ANL) has developed a low-cost cobalt-based catalyst for the production of hydrogen in a proton exchange membrane water electrolyzer (PEMWE). volts (Nafion 212 membrane) and low degradation in an accelerated stress test.

Heliogen and Bloom Energy demonstrate production of low-cost green hydrogen; concentrated solar and high-temp electrolysis

Green Car Congress

When combined with Bloom’s proprietary solid oxide, high-temperature electrolyzer, hydrogen can be produced 45% more efficiently than low-temperature PEM and alkaline electrolyzers. Electricity accounts for nearly 80% of the cost of hydrogen from electrolysis. Source: Heliogen.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure). Lopez, J.S.,

Researchers in Australia develop low-cost water-splitting catalyst that offers comparable performance to platinum

Green Car Congress

Iron and nickel, which are found in abundance on Earth, would replace precious metals ruthenium, platinum and iridium that up until now are regarded as benchmark catalysts in the water-splitting process. —Suryanto et al. —Prof Zhao. Iron and nickel are currently priced at $0.13 and $19.65 a kilogram. and $69.58 Suryanto et al.

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

Green Car Congress

The low cost of porous melamine means that the material could be deployed widely. In contrast, the melamine porous network with DETA and cyanuric acid modification captures CO 2 at about 40 degrees Celsius, slightly above room temperature, and releases it at 80 degrees Celsius, below the boiling point of water.

Penn State, FSU team develops low-cost, efficient layered heterostructure catalyst for water-splitting

Green Car Congress

A team of scientists from Penn State and Florida State University have developed a lower cost and industrially scalable catalyst consisting of synthesized stacked graphene and W x Mo 1–x S 2 alloy phases that produces pure hydrogen through a low-energy water-splitting process.
