MIT researchers propose mechanism for overcoming bottleneck in electroreduction of CO2

Green Car Congress

Researchers at MIT have identified , quantified, and modeled a major reason for the poor performance of electroreduction processes to convert CO 2 to fuel or other useful chemicals. In all of these, I think the hydrogen co-evolution becomes a bottleneck. The research was supported by Shell, through the MIT Energy Initiative.

Study finds the wettability of porous electrode surfaces is key to making efficient water-splitting or carbon-capturing systems

Green Car Congress

As water-splitting technologies improve, often using porous electrode materials to provide greater surface areas for electrochemical reactions, their efficiency is often limited by the formation of bubbles that can block or clog the reactive surfaces. As a result, there were substantial changes of the transport overpotential.

MIT researchers develop oxygen permeable membrane that converts CO2 to CO

Green Car Congress

MIT researchers have developed a new system that could potentially be used for converting power plant emissions of carbon dioxide into carbon monoxide, and thence into useful fuels for cars, trucks, and planes, as well as into chemical feedstocks for a wide variety of products.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. (B) MS signal and SFE values for a wireless configuration. Reece et al.

MIT researchers advancing development of supercritical water upgrading of heavy crude; lower cost, energy use and CO2

Green Car Congress

Findings by MIT researchers could help advance the commercialization of supercritical water technology for the desulfurization and upgrading of high-sulfur crude oil into high-value, cleaner fuels such as gasoline without using hydrogen—a major change in refining technology that would reduce costs, energy use, and CO 2 emissions.

MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. Applying the model, they found that the average LCOE associated with meeting this seasonal imbalance is $2400/MWh using a HFGT fueled with green hydrogen and $3000/MWh using a LI.

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. By doing so, he aims to imitate the process of photosynthesis, by which plants harvest sunlight and convert the energy into chemical form.
