报 告 人：Dr. Aliakbar Hassanpouryouzband

报 告 人：Aliakbar Hassanpouryouzband is Chancellor's Fellow in Net Zero Technologies (since 2023) at the School of Geosciences, University of Edinburgh. He started his journey there in 2019 as a postdoctoral research associate. His research focuses on CCUS and large-scale sustainable energy generation, transport, and storage with particular focus on hydrogen. He completed his PhD at Heriot-Watt University in 2019, specializing in low-carbon energy production and CO2 capture and storage, a part of which was conducted at MIT's Molecular Engineering Laboratory. Aliakbar received his BSc (2013) and MSc (2015) in Petroleum Engineering from Sharif University of Technology.

报告摘要：Exploration for commercially viable natural hydrogen accumulations within the Earth's crust, here compared to ‘foraging’ for wild food, holds promise. However, a potentially more effective strategy lies in the in situ artificial generation of hydrogen in natural underground reservoirs, akin to ‘farming’. Both biotic and abiotic processes can be employed, converting introduced or indigenous components, gases, and nutrients into hydrogen. Through studying natural hydrogen-generating reactions, we can discern pathways for optimized engineering. Some reactions may be inherently slow, allowing for a ‘seed and leave’ methodology, where sites are infused with gases, nutrients, and specific bacterial strains, then left to gradually produce hydrogen. However, other reactions could offer quicker outcomes to harvest hydrogen. A crucial element of this strategy is our innovative concept of ‘X’ components—ranging from trace minerals to bioengineered microbes. These designed components enhance biotic and/or abiotic reactions and prove vital in accelerating hydrogen production. Drawing parallels with our ancestors' transition from hunter-gathering to agriculture, we propose a similar paradigm shift in the pursuit of hydrogen energy. As we transition towards a hydrogen-centric energy landscape, the amalgamation of geochemistry, advanced biology, and engineering emerges as a beacon, signalling a pathway towards a sustainable and transformative energy future.
