Solar steam reforming methane is one of the energy effective technologies for producing lowcarbonhydrogen from methane. 12 The use of concentrated solar energy for ahigh-temperature heat source to the SRM process has the potential of avoiding up to 35–40% of the CO 2 emissions derived from the conventional SRM process based on fossil fuel ...

The reaction used to make ammonia for synthetic fertilizer requires hydrogen. Nowadays, that hydrogen is stripped from methane, creating CO2 as a by-product. Licht et al. demonstrate a relatively efficient electrochemical process in which water and nitrogen react directly to form ammonia. The approach removes the need for an independent hydrogen generation step.

Solar-thermal desalination (STD) is a potentially low-cost, sustainable approach for providinghigh-quality fresh water in the absence of water and energy infrastructures. Despite recent efforts to advance STD by improving heat-absorbing materials and system designs, the best strategies for maximizing STD performance remain uncertain. To address this problem, we identify three major steps in ...
