Decarbonisation Of Food Cold Chain Through Integrated Hydrogen Technologies

英国政府承诺到2050年将碳排放量减少到净零。为了实现这一承诺，供暖和制冷的脱碳至关重要，因为它占英国二氧化碳排放量的三分之一以上。一个可能的解决办法是建立以氢为基础的能源基础设施，促进用可持续能源替代化石燃料。基于氢的未来能源系统的核心将是氢燃料电池（hfc）的部署，将可持续来源的氢（例如来自太阳能和风能）转化为电能，因为它们高效、经济且可扩展。燃料电池的全球市场预计将达到14美元。到2027年，全球对氢气的需求将超过7000万吨，每年增长500万吨。如果氢要成为英国未来能源系统的一个组成部分，并协助加热和冷却的脱碳，那么就需要技术来促进氢的安全有效地输送到最终用途。我们建议开发综合氢技术，同时提供氢的控制释放，以满足燃料电池的电力需求和冷生产。这项技术的关键是金属氢化物（MH）储存的吸热分解产生冷却，所得的氢供应燃料电池。通过向以氢为基础的净零经济过渡，我们的新技术为英国食物链（农业生产、制造、分销、零售和消费）的脱碳提供了机会，英国食物链占英国能源消耗总量的18%，二氧化碳排放量为1.15亿吨。

The UK government is committed to reducing carbon emissions to net zero by 2050. In order to meet this commitment, it is essential that heating and cooling is decarbonised as it accounts for over a third of CO2 emissions in the UK. A potential solution would be the establishment of a hydrogen-based energy infrastructure facilitating the replacement of fossil fuels by sustainable energy sources. Central to a future energy system based upon hydrogen would be the deployment of hydrogen fuel cells (HFCs) to convert sustainably derived hydrogen (e.g. from solar and wind) to electricity, as they are highly efficient, economic and scalable. The global market for fuel cells is projected to reach US$14. 6 billion by 2027, and the global demand for hydrogen is now over 70Mt rising by 5 Mt a year. If hydrogen is to be an integral part of the UK's future energy system and assist in decarbonisation of heating and cooling, then technologies are required to facilitate the safe and efficient delivery of hydrogen to end use applications. We propose the development of integrated hydrogen technologies that will simultaneously provide the controlled release of hydrogen to service fuel cell power needs and cold production. Key to this technology is the endothermic decomposition of a metal hydride (MH) store to generate cooling, with the resultant hydrogen supplying a fuel cell. By transitioning to a hydrogen-based net-zero economy, our new technology provides an opportunity to assist in the decarbonisation of the UK food chain (agricultural production, manufacturing, distribution, retail and consumption) which is responsible for 18% of the total UK energy use or 115 MtCO2 emissions.
