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).

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.

Swiss team develops effective and low-cost solar water-splitting device; 14.2% solar-to-hydrogen efficiency

Green Car Congress

As the V OC of the presented c-Si cells is only ∼600 mV, four cells need to be connected in series to achieve stable water splitting performance. We demonstrate in this study that, thanks to their high V OC , three series-connected SHJ cells can already stably drive the water splitting reaction at unprecedented SHE. Schüttauf et al.

MIT Researchers Identify New Low-Cost Water-Splitting Catalyst

Green Car Congress

Daniel Nocera and his associates have found another formulation, based on inexpensive and widely available materials, that can efficiently catalyze the splitting of water molecules using electricity. That’s no longer a concern for us ,” he says, although that part of the research has not yet been formally reported. Earlier post.).

Haldor Topsoe to build large-scale SOEC electrolyzer manufacturing facility to meet customer needs for green hydrogen

Green Car Congress

With efficiencies above 90%, Topsoe’s proprietary SOEC electrolyzers offer superior performance in electrolysis of water into hydrogen—e.g., Solid oxide electrolysis cell (SOEC) technology is attractive because of unrivaled conversion efficiencies—a result of favorable thermodynamics and kinetics at higher operating temperatures.

DOE’s $10M Advanced Water Splitting Materials Consortium accelerating development of green hydrogen production

Green Car Congress

The Energy Department (DOE) recently announced $10 million, subject to appropriations, to support the launch of the HydroGEN Advanced Water Splitting Materials Consortium ( HydroGEN ). Chemical Catalysts for Bioenergy (ChemCat Bio) is dedicated to identifying and overcoming catalysis challenges for biomass conversion processes.

Raven SR & Hyzon Motors to build up to 100 waste-to-hydrogen hubs

Green Car Congress

As part of the agreement, Hyzon is acquiring a minority interest in Raven SR. This permits the control of the rotary reformer when there is water content or chemical makeup variation in the feedstock, such as in MSW. Raven SR , a renewable fuels company, and Hyzon Motors Inc., C) at the front up to 1,200°F at the exit end.
