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 engineers create 2D polymer that self-assembles into sheets

Green Car Congress

Using a novel polymerization process, MIT chemical engineers have created a new two-dimensional polymer that self-assembles into sheets, unlike all other polymers which form one-dimensional chains.

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. The findings could spur progress on developing a variety of materials and designs for electrochemical carbon dioxide conversion systems. —Soto 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.

million in funding for 12 projects as part of Phase 1 of the Advanced Research Projects Agency-Energy’s (ARPA-E’s) FLExible Carbon Capture and Storage (FLECCS) program. The post-combustion outlet gas is more easily separated into water and CO 2 to the pipeline, thereby lowering the electricity costs of grids with high levels of VRE.

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.

Energy researchers: clean US hydrogen economy is within reach, but needs a game plan

Green Car Congress

Hydrogen and its derivatives could be that fuel, argues a commentary by four energy researchers in the journal Joule. However, they note, a clean US hydrogen economy will require a comprehensive strategy and a 10-year plan. John Deutch, an emeritus Institute Professor at MIT. —Arun Majumdar.
