    Abstract: The present disclosure relates to algae cultivation including the integration of liners for large-scale open algal biomass to facilitate algae facility commercial scale-up operations. Liners include those having a first portion having a first thickness and a second portion comprising a second thickness, wherein the first thickness and the second thickness are different. Liners also include those having a first portion having a first thickness, a second portion comprising a second thickness, and a third portion comprising a third thickness, wherein the first thickness, the second thickness, and the third thickness are different.

    Abstract: Systems and methods are provided for hydrogenation of CO2 in a reverse flow reactor environment via a reverse water gas shift reaction. A reverse flow reactor environment is suitable for performing endothermic reactions at high temperatures, where a reactant flow is passed into the reactor in a first portion of the cycle in a first flow direction while a combustion or heating flow is passed into the reactor during a second portion of the reaction cycle from the opposite direction. This can allow for efficient heating of surfaces within the reactor to provide heat for the endothermic reverse water gas shift reaction while reducing or minimizing incorporation of combustion products into the desired reaction products.

    Abstract: Systems and methods are provided for performing CO2 sorption and desorption using a sorbent structure with an integrated heat pump. The integrated heat pump can allow at least a portion of the heat generated during sorption to be recovered by forming steam from water. The steam raised during the sorption process can then be compressed and optionally heated to raise the temperature of the steam. The compressed and optionally heated steam can then be used as at least a portion of the steam for desorption of CO2 in the same sorbent bed or a different sorbent bed. By recovering the heat of sorption to raise steam, substantial energy savings can be achieved relative to a conventional process.
