项目摘要
'Solar fuels' are synthetic, storable, high energy density chemicals, produced using sunlight as the sole energy source. Solar fuels include hydrogen (termed "golden hydrogen"), which is generated by solar-driven water reduction, and various carbon-based fuels produced through the reduction of carbon dioxide. Fuels synthesised in this way can contribute towards reaching net zero greenhouse gas emissions. The projected increase in global power demand necessitates urgent decarbonisation of power sources and fuels to limit the release of CO2 into the atmosphere. One major pathway to achieving this goal is to harness and utilise renewable energies. These, however, are intermittent and so require management, for example via energy storage in chemical bonds.Photoelectrochemical reactors present a potential technological solution for producing solar fuels at scale. Such reactors combine - in a single device - the functions of photovoltaic (PV) panels and electrolysers; the former convert solar energy to electrical energy, while the latter convert electrical energy to chemical energy. In photoelectrochemical reactors, photoabsorbing components are immersed in liquid media. This approach was conceived to lower the capital cost of solar fuel production compared with commercially available PV + electrolyser systems. The overarching aim of this research is to answer the question 'What might an industrial scale photoelectrochemical reactor system ultimately look like?'. Development of up-scaled reactors is a multidisciplinary challenge, involving material science, (photo)electrochemistry, electrochemical engineering and optics, supplemented by numerical modelling of the complete system to guide its design and optimisation. These many considerations need to be addressed simultaneously. By answering some of these critical questions and developing large-scale prototype reactors, this project will accelerate the development of sustainable hydrogen production using photoelectrochemical devices and bring us closer to the decarbonisation of our energy systems that we urgently need.
“太阳能燃料”是一种合成的、可储存的、高能量密度的化学物质,以阳光为唯一能源生产。太阳能燃料包括通过太阳能驱动的水减少产生的氢气(被称为金氢),以及通过减少二氧化碳产生的各种碳基燃料。以这种方式合成的燃料可以为实现温室气体净零排放做出贡献。预计全球电力需求将会增加,因此迫切需要对能源和燃料进行脱碳,以限制二氧化碳向大气中的排放。实现这一目标的一个主要途径是利用和利用可再生能源。然而,这些都是间歇性的,因此需要管理,例如通过化学键存储能量。光电化学反应器为大规模生产太阳能燃料提供了一种潜在的技术解决方案。这类反应堆将光伏(PV)电池板和电解槽的功能结合在一起;前者将太阳能转化为电能,后者将电能转化为化学能。在光电化学反应器中,光吸收元件浸入液体介质中。与商用的光伏+电解槽系统相比,这种方法旨在降低太阳能燃料生产的资本成本。这项研究的首要目的是回答这样一个问题:一个工业规模的光电化学反应系统最终会是什么样子?大规模反应堆的开发是一个多学科的挑战,涉及材料科学、(照片)电化学、电化学工程和光学,并辅之以整个系统的数值模拟,以指导其设计和优化。这许多考虑因素需要同时解决。通过回答其中一些关键问题和开发大型原型反应堆,该项目将加快利用光电化学设备进行可持续氢气生产的发展,并使我们更接近我们迫切需要的能源系统的脱碳。
