(3) Standard of review The Secretary shall review activities carried out under the program described in paragraph (1) to determine the achievement of technical milestones. (4) Prohibition No funds allocated to the program described in paragraph (1) may be obligated or expended for commercial application of energy technology. (c) Biochemistry, replication of natural photosynthesis, and related processes (1) In general The Secretary shall carry out under the Initiative a program to support research needed to replicate natural photosynthetic processes by use of artificial photosynthetic components and materials. (2) Activities As part of the program described in paragraph (1)— (A) the Director of the Office of Basic Energy Sciences shall support basic research to expand fundamental knowledge to replicate natural synthesis processes, including— (i) the photoinduced reduction of dinitrogen to ammonia; (ii) the absorption of carbon dioxide from ambient air; (iii) molecular-based charge separation and storage; (iv) photoinitiated electron transfer; and (v) catalysis in biological or biomimetic systems; (B) the Associate Director of Biological and Environmental Research shall support systems biology and genomics approaches to understand genetic and physiological pathways connected to photosynthetic mechanisms
