## ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture ##### 30 April 2010 The US Department of Energy is awarding$106 million in funding for 37 research projects selected in the second round by the DOE’s Advanced Research Projects Agency-Energy (ARPA-E). (Earlier post.)

ARPA-E’s first solicitation awarded $151 million to 37 projects aimed at transformational innovations in energy storage, biofuels, carbon capture, renewable power, building efficiency, vehicles, and other areas. (Earlier post.) The second round was focused specifically on three areas of technology representing new approaches for advanced microbial biofuels (electrofuels); much higher capacity and less expensive batteries for electric vehicles; and carbon capture. More than 540 initial concept papers were received in the three focus areas. Of those, approximately 180 full applications were encouraged, and 37 final awardees were selected through a rigorous review process with input from multiple review panels composed of leading US science and technology experts and ARPA-E’s program directors. Evaluations were based on scientific and technical merit and the potential for high impact on national energy and economic goals. The grants will go to projects in 17 states. Of the lead recipients, 24% are small businesses, 57% are educational institutions, 11% are national labs, and 8% are large corporations. Electrofuels: Biofuels from Electricity. 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 approaches will use organisms able to extract energy from other sources, such as solar-derived electricity or hydrogen or earth-abundant metal ions. Theoretically, such an approach could be more than 10 times more efficient than current biomass approaches.

Codexis Inc.
(Nexant Inc.)
Solvents / Catalysts: Low-Cost Biocatalyst for Acceleration of Energy Efficient CO2 Capture Solvents
Codexis proposes to develop low-cost enzymes for carbon capture from coal-fired power plants. Carbonic anhydrases (CAs), enzymes which catalyze CO2 hydration, can enable the use of otherwise slow capture solvents with dramatically lower energy losses than current technology. Existing CAs are prohibitively expensive due to their low activity and short lifetime and high manufacturing (fermentation) costs. Codexis will apply its directed evolution technology to develop lower-cost thermophile-derived CAs with improved activity and stability and its strain evolution technology to develop a low-cost manufacturing process for the enzyme.
$4,657,045 Lawrence Livermore National Laboratory (GE Energy, Univ. of Pittsburgh) Solvents / Catalysts: Catalytic Improvement of Solvent Capture Systems Synthetic small-molecule catalysts can greatly speed the absorption of CO2 into liquid solvents and can enable solvents that bind CO2 less tightly. This project combines scientific experience in creating synthetic small-molecule catalysts (LLNL, UIUC) with industrial experience to make them operationally useful (B&W) in both existing and new CO2-capture systems. The team will use computational design techniques to develop small molecule catalysts that mimic enzyme functions; essential structural features will be extracted from enzyme data. Another key technical goal is protecting catalysts from degradation in industrial environments.$3,665,000

$3,663,696 University of Colorado-Boulder (Los Alamos National Laboratory, EPRI) Membranes: Gelled ionic liquid membranes UC Boulder will be developing novel gelled ionic liquid membranes, which provide mechanical rigidity into what is normally a liquid solvent, allowing extremely thin membranes to be fabricated. Since the membrane permeance increases as the membranes become thinner, higher fluxes of CO2 can be selectively passed through the membrane, reducing the cost and size of membrane treatment for flue gas.$3,144,646
GE Global Research Center
(GE Energy, Univ. of Pittsburgh)
Phase Change: CO2 Capture Process Using Phase-Changing Absorbents
This GE-led team will develop a novel cost-efficient CO2 capture process that uses a liquid absorbent which, upon contact with CO2, changes into a solid powder. The solid can be separated and the CO2 can be released by heating, after which the absorbent returns to its liquid form. Because the absorbent solid contains a high percentage of CO2, the energy efficiency of the process is improved over current technology, and compression and capital costs are reduced. The goal is to achieve < 10% parasitic power load at 90% CO2 capture and <$25/ton CO2 capture cost. In addition, the approach offers a smaller footprint and would be retrofittable into existing plants.$3,017,511
Notre Dame University
(Mid-Atlantic Technology, Research, & Innovation Center)
Phase Change: Phase-changing ionic liquids for CO2 capture A recent discovery by Notre Dame has identified a class of ionic liquid materials which undergo a phase transition from solid phase to liquid when reacting with CO2. A detailed synthetic study of these new compounds will aim to identify materials best suited for carbon capture applications. Lower heats of regeneration are required with these materials, since the heat of fusion during the phase change reduces the amount of energy input to release the CO2 that is captured. $2,559,563 Research Triangle Institute (BASF) Solvents: CO2-binding organic liquids RTI and BASF are teaming to explore a new class of materials known as CO2 binding organic liquids. These co-solvents form a miscible mixture that becomes an ionic liquid with high CO2 uptake upon reaction with flue gas. By using solvents that are not compatible with water, low energy separation techniques may be used to remove the water, which would normally require an energy intensive distillation process.$2,000,000

Membranes / Solvents: A Solvent/Membrane Hybrid Post-combustion CO2 Capture Process for Existing Coal-Fired Power Plants
The University of Kentucky-led team will develop a hybrid absorption solvent/catalytic membrane post-combustion CO2 capture process for existing coal-fired power plants. The membrane acts as a catalytic separator, coupling nanofiltration separation and catalysis functions to produce a concentrated permeate that lowers regeneration costs. The solvents of interest include aqueous ammonium and some typical alkyl amines (e.g., MEA). This catalytic membrane reactor could greatly reduce the energy penalty for CO2 capture, and the membrane unit could be conveniently integrated into the typical carbon capture process for fossil fuel-fired power plants.

This Georgia Tech proposal will incorporate metal organic frameworks—new compounds that show great promise in carbon capture—into hollow fiber membranes for improved CO2 selectivity. The use of hollow fiber membranes allows high surface area, and the selective incorporation of MOFs into the polymer matrix will improve throughput and selectivity, helping to reduce capture costs.
$1,000,000 MIT (Siemens) Sorbents: Electrochemically Mediated Separation for Carbon Capture and Mitigation The MIT-led team will develop electrochemically mediated separation (ECMS) processes for post--combustion CO2 capture at coal-fired power plants.

The project will involve molecular modeling and experimental optimization of carrier structure, fabrication and evaluation of prototype separation units.$1,000,000
Oak Ridge National Laboratory
(Georgia Institute of Technology)
Sorbents: Hollow fiber membranes with ionic liquids for CO2 capture The team from Oak Ridge and Georgia Tech are using hollow fiber membranes to provide a high surface area support for ionic liquids to capture and release CO2. In order to provide rapid adsorption and desorption of the CO2, water or steam are passed through the fibers which rapidly heat or cool the sorbent. These fast thermal cycles can reduce the capital costs by minimizing the equipment needed for CO2 capture. $987,547 ### Comments A seemingly prudent expenditure to accomplish two basic goals: 1) Improve chemical storage systems to 400Wh/kg 2) Convert CO2 to useful biofuels The first area appears to have some very good potential. Especially interesting is the A123 low cost manufacturing process. Should this be successful, a proprietary low cost process <$.10/Wh would compete with low cost labor overseas - meaning new JOBS.

The second emphasizing CO2-based electrofuels will be interesting to see scalability. Most processes seem to produce small output of usable fuels given the electrical inputs. But more efficient than photosynthesis alone.
