"ASCENT will provide a robust proof-of-concept of three related high temperature processes; each will lead to a step-change in efficiency of carbon removal in three types of pre-combustion capture, producing the hydrogen needed for highly efficient low-carbon power production. The project brings together five small and medium enterprises preparing to launch these concepts with the support of leading research institutes, universities and industrial partners.The essential feature linking the three technologies is the use of a high temperature solid sorbent for the simultaneous separation of CO2 during conversion of other carbon containing gases (CO and CH4) into H2. Each technology provides a step-change in efficiency because they all separate the CO2 at elevated temperatures (>300°C) providing for more efficient heat integration options not available in technologies where the separation occurs at lower temperatures. Each process matches both endothermic and exothermic heat requirements of associated reactions and sorbent regeneration in an integrated in situ approach.The synergies between the three technologies are strong, allowing both multiple interactions between the different work packages and allowing a consistent framework for cross-cutting activities across all the technologies. Each technology will be proven under industrially relevant conditions of pressure and temperature, at a scale that allows the use of industrially relevant materials that can be manufactured at a scale needed for real implementation. This represents a necessary step to be taken for each of the technologies before setting out on the route to future demonstration level activities.ASCENT, Advanced Solid Cycles with Efficient Novel Technologies, addresses the need for original ideas to reduce the energy penalty associated with capturing carbon dioxide during power generation, and create a sustainable market for low carbon emission power with low associated energy penalties"
