受COVID-19疫情影响，全球对减少温室气体排放的需求比以往任何时候都更加明确。二氧化碳排放量的减少是可记录的，表明改变是可能的。英国政府已认识到COVID-19后的复苏应以“绿色”举措为核心。但停止全球旅行和国际贸易的影响对经济和生计也同样具有破坏性。运输需要能源，公路运输的某些部门甚至航空的某些方面的电气化是可能的，但目前和设想的电池能量密度并没有显示出大型客运或货运飞机完全电动并具有可行的航程和有效载荷的可行替代方案。这导致了对替代和绿色燃料的需求。氢如果从可持续能源产生，则是碳氢化合物的清洁替代品，无论是化石还是合成来源。但氢的能量密度低于碳氢化合物，因此要实现可行航程的氢体积/质量，飞机必须具有非常轻的结构和储氢罐，以抵消这种较低的能量密度。该项目将有助于开发TISICS独特的轻质净形空间聚焦化学和气体罐技术，可扩展以满足航空所需的容量和经济性。坦克将采用轻型薄壁铝扩散结合，以避免需要较低的完整性和较重的传统焊接制造。净成形技术可实现具有集成安装结构的自适应油箱设计，并可从铝过渡到高完整性不锈钢或钛管道系统。与传统航空航天制造相比，制造过程中的废料通常为5%，而传统航空航天制造中购买的材料在最终产品中的残留率不到10%。这意味着供应链中的能源和二氧化碳排放量将进一步显著减少。这些储罐的可扩展技术的发展超出了空间系统的尺寸，这对工具提出了新的挑战，TISICS建立在30年的跨多个部门的创新金属复合材料研究历史的基础上，能够开发我们的空间推进剂贮箱，气体和化学推进，成为一个规模化的制造方法，能够提供大型，安全的长期使用寿命的氢存储罐，用于未来的航空使用。这建立在我们为当前和未来一代燃油效率飞机提供轻量化部件的广泛工作基础上。在英国开发这项技术将增强英国现有的制造和出口市场地位。这维持了制造业就业机会，并创造了新的先进工程和制造业就业机会，为英国航空航天，航天和汽车行业提供服务，并为英国经济创造了进一步的出口机会。氢运输的世界领导地位对于超越碳氢燃料并通过清洁车载混合动力或燃料电池发电来增强电气化至关重要。但这需要重量轻的氢气罐。

The global need for greenhouse gas emission reduction is clearer than ever as a result of the COVID-19 Pandemic. Reductions in CO2 emissions are recordable and show that change is possible. The UK government has recognised that a post COVID-19 recovery should have 'green' initiatives at its core. But the impact of stopping global travel and international trade has been equally damaging to economies and livelihoods. Therefore a balance is needed to recover transport businesses and in particular aviation without continued emissions and damage to the environment.Transport needs an energy source, electrification of some sectors of road transport and even some aspects of aviation is possible but current and envisaged energy density for batteries do not show a viable alternative for large passenger or freight aircraft to be entirely electric and have viable range and payload. This leads to the need for alternative and green fuels. Hydrogen if generated form sustainable energy sources is a clean alternative to hydrocarbons whether fossil or synthetically sourced. But the energy density of hydrogen is lower than hydrocarbons and therefore to achieve the volume/mass of hydrogen for viable range, aircraft must have very light structures and hydrogen storage tanks to offset this lower energy density.This project will help develop TISICS unique lightweight net shape space focused chemical and gas tank technology to be scalable to meet the capacity and economics needed for aviation. The tanks will utilise lightweight thin wall aluminium diffusion bonded to avoid the need for lower integrity and heavier conventional welded manufacturing. The net shape technology enables adaptable tank designs with integrated mounting structures and transitions from aluminium to high integrity stainless steel or titanium pipework.The fabrication process has the additional benefits of low waste manufacture typically 5% compared to conventional aerospace manufacturing where less than 10% of the material bought remains in the final product. This represents significant further energy and hence CO2 emission savings in the supply chain.The development of the scalable technology for these tanks to beyond space system size presents new challenges for tooling, process conditions and inspection that will be addressed in this project.TISICS builds on a 30 year history of innovative metal composite research across multiple sectors to be in a position to develop our space propellant tanks for gas and chemical propulsion, into a scalebale manufacturing method capable of delivering large, safe long service life hydrogen storage tanks for aviation use in the future. This builds on our extensive work on lightweight parts for current and future generation fuel efficient aircraft.Developing this technology in the UK will enhance the existing manufacturing and export market position held by the UK. This sustains manufacturing jobs and creates new advanced engineering and manufacturing jobs supplying UK aerospace, space and automotive sectors and creating further export opportunities for the UK economy.World leadership in hydrogen for transport is essential to move beyond hydrocarbon fuels and augments electrification through clean onboard hybrids or fuel cell power generation. But this needs light-weight hydrogen tanks.
