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.

由于2019冠状病毒病大流行，全球减少温室气体排放的必要性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。英国政府已经认识到，新冠肺炎疫情后的复苏应该以“绿色”倡议为核心。但是，停止全球旅行和国际贸易对经济和生计的影响同样具有破坏性。因此，在不继续排放和破坏环境的情况下恢复运输业务，特别是航空业，需要一种平衡。运输需要一种能源，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一种可行的替代方案，可以让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。这导致了对替代和绿色燃料的需求。氢气如果是由可持续能源产生的，无论是化石能源还是合成能源，都是碳氢化合物的清洁替代品。但是氢气的能量密度比碳氢化合物低，因此为了实现可行范围内氢气的体积/质量，飞机必须有非常轻的结构和储氢罐来抵消这种较低的能量密度。该项目将有助于开发TISICS独特的轻质网状空间化学和气罐技术，以满足航空的容量和经济需求。储罐将利用轻质薄壁铝扩散粘合，以避免需要较低的完整性和较重的传统焊接制造。网形技术使储罐设计具有适应性，具有集成的安装结构和从铝到高完整性不锈钢或钛管道的过渡。与传统航空航天制造相比，该制造过程还有一个额外的好处，即低废物制造（通常为5%），在传统航空航天制造中，购买的材料中只有不到10%留在最终产品中。这意味着在供应链中进一步节省大量能源和二氧化碳排放。这些储罐的可扩展技术的发展超出了空间系统的规模，这对该项目将解决的工具、工艺条件和检查提出了新的挑战。TISICS建立在30年的创新金属复合材料研究历史的基础上，跨越多个领域，能够开发我们用于气体和化学推进的空间推进剂储罐，成为一种可扩展的制造方法，能够为未来的航空用途提供大型，安全，长使用寿命的储氢罐。这建立在我们为当前和未来一代节油飞机的轻质部件所做的广泛工作的基础上。在英国开发这项技术将增强英国现有的制造业和出口市场地位。这维持了制造业的就业机会，并为英国航空航天、航天和汽车行业创造了新的先进工程和制造业就业机会，并为英国经济创造了进一步的出口机会。要想超越碳氢化合物燃料，并通过清洁的车载混合动力或燃料电池发电增强电气化，世界在氢运输领域的领导地位至关重要。但这需要轻便的氢气罐。
