A team of researchers at MIT has described a framework for efficiently coupling the power output of a series-connected string of single-band-gap solar cells to an electrochemical process that produces storable fuels. The original demonstration leaf in 2011 had low efficiencies, converting less than 4.7% Source: Winkler et al.
By doing so, he aims to imitate the process of photosynthesis, by which plants harvest sunlight and convert the energy into chemical form. 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.
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. aligned with the low-cost systems engineering and.

Researchers at MIT and startup Novogy have engineered bacteria and yeast ( Escherichia coli , Saccharomyces cerevisiae and Yarrowia lipolytica ) used as producer microbes in biofuel production to use rare compounds as sources of nutrients. However, this is not the case for the more advanced biofuels and biochemicals under development.
an integrated stationary fuel cell manufacturer, to develop a durable, low-cost, and high-performance electrochemical cell to convert natural gas and other methane-rich gas into methanol, a major chemical commodity with worldwide applications in the production of liquid fuels, solvents, resins, and polymers. Earlier post.)
Today’s technologies for making biofuels all rely on photosynthesis—either indirectly by converting plants to fuels or directly by harnessing photosynthetic organisms such as algae. This process is less than 1% efficient at converting sunlight to stored chemical energy. Electrofuels: Biofuels from Electricity. Engineering E.
This project will optimize fuel-based control of novel combustion strategies in light- and heavy-duty vehicles to enable diesel-like efficiencies with ultra-low engine-out emissions. This project will develop a new process that enables low-cost, domestic manufacturing of magnesium. valve train vs. bearings). 3,500,000. .
One program, Reducing Emissions using Methanotrophic Organisms for Transportation Energy (REMOTE, earlier post ), provides $34 million to 15 projects to find advanced biocatalyst technologies that can convert natural gas to liquid fuel for transportation. process intensification approaches for biological methane conversion.
A team of researchers at MIT and Tsinghua University has developed a high-rate, high-capacity and long-lived anode for Li-ion batteries comprising a yolk-shell nanocomposite of aluminum core (30 nm in diameter) and TiO 2 shell (~3 nm in thickness), with a tunable interspace (Al@TiO 2 , or ATO). Earlier post.). —Li et al.

The team will. field trials.
Methane Converter to Electricity and Fuel. Bio2Electric will develop a small-scale reactor that converts natural. convert natural gas into transportable liquids in one step. areas to convert otherwise wasted gas into usable chemicals that. sunlight through low-cost, plastic light-guiding sheets and then.
The MIT will develop a new generation of power electronics based on vertical gallium nitride (GaN) superjunction diodes and transistors that can vastly exceed the performance of today’s GaN power devices. Massachusetts Institute of Technology. 8" GaN-on-Si Super Junction Devices for Next Generation Power Electronics - $4,521,601.
The University of Wisconsin-Madison and ExxonMobil announced a two-year renewal of an agreement to research the fundamental chemistry of converting biomass into transportation fuels. Over the past two years, research has focused on a multistep approach for converting cellulosic biomass to transportation fuels. —Professor Huber.
The gasification technology complements Aemetis’ current license with LanzaTech for syngas-to-ethanol conversion, providing Aemetis with a complete technology solution to produce locally-sourced, low-carbon cellulosic ethanol. More than $130 million was invested in the development of the InEnTec gasification technology.
The US Department of Energy (DOE) selected eight projects to advance the development of transformational oxy-combustion technologies capable of high-efficiency, low-cost carbon dioxide capture from coal-fired power plants. Unity Power Alliance.
Michigan Technological University will use advanced ceramic-based 3D printing technology to develop next-generation light, low-cost, ultra-compact, high-temperature high-pressure (HTHP) heat exchangers. Additively Manufactured High Efficiency and Low-Cost sCO 2 Heat Exchangers – $1,500,000. The Ohio State University.
Or, new-ish, at least—there's a ruggedized and ultra low-cost GelSight-style fingertip sensor, plus a nifty new kind of tactile sensing skin based on suspended magnetic particles and machine learning. The DIGIT touch sensor is based on the GelSight style of sensor, which was first conceptualized at MIT over a decade ago.
Colorado State University will develop a novel, low-cost turbo-compression cooling system that utilizes the ultra-low-grade waste (less than 150°C) heat available in many industrial processes, the energy from which is not traditionally recovered. Colorado State University. Massachusetts Institute of Technology. Yale University.
The stator converts its thrust force and torque into longitudinal and meridian motions of the torus wheel, respectively, making the torus work as an omnidirectional wheel on a plane. body length per second, close to five times faster than the fastest similar soft swimmers, and also a high-power efficiency with lowcost of energy.

The above quantum sensor for the presence of the SARS-CoV-2 virus uses only low-cost materials. MIT The nano-diamonds and the other materials used in the test are cheap. We hope to get promising results very soon," says researcher Changhao Li , a quantum engineer at MIT.
The company calls this dual-chemistry hybrid pack Gemini, and recently told Charged that it is enabled by utilizing cutting-edge cell technologies and a proprietary high-power-density DC-DC converter. The challenge is that anode-free cells still have low cycle life. In January, ONE retrofitted a Tesla Model S with an experimental 203.7
Fisker $80,000 Karma series luxury 50-mile range series PHEV, S Sunset convertible version.Partnering with Quantum Technologies. Several aftermarket companies and organizations have converted hundreds of Priuses -- see Where PHEVs Are.) But we want to give them cause to continue to press forward." ( MIT Technology Review ).
PPPL converted Spitzer’s Model C stellarator into a tokamak in 1969. Type One’s design, like that of Thea Energy’s Eos, makes use of high-temperature superconducting magnets , which provide higher magnetic strength, require less cooling power, and could lower costs and allow for a more compact and efficient reactor.
