Heating and cooling are essential to our lives. We rely on them for comfort in our homes and vehicles, and businesses need heating and cooling for productive workplaces and industrial processes. Taken together, space and process heating and cooling represent the biggest contribution to the UK's energy consumption, and the biggest source of greenhouse gas emissions.Heating is primarily provided from burning natural gas, whereas cooling is primarily provided from compressing volatile fluorinated gases. However, these conventional technologies are neither efficient, not friendly to the environment.Barocaloric effects are reversible thermal changes that occur in mechanically responsive solids when subjected to changes in pressure. These effects are analogous to the pressure-induced thermal changes in gases that are exploited in current heat pumps, but they promise higher energy efficiencies and obviate the need for harmful greenhouse gases.We aim at developing an energy-efficient barocaloric heat pump based on novel barocaloric hybrid composite materials that combine the best properties of organic barocaloric materials, namely extremely large pressure-driven thermal changes, and the best of inorganic barocaloric materials, namely high thermal conductivity and low hysteresis.A technological transformation of this magnitude will require the development of bespoke economic and policy strategies for its successful deployment. Therefore, we aim at developing a fully integrated bespoke economic and policy strategy that will support the innovation of BC heat pumps through to commercialisation.The achievement of heat pumps that operate using barocaloric materials instead of gases will permit decarbonising heating and cooling, provide energy independence, and enable the UK to become the world leader on this emerging technology.

供暖和冷却对我们的生活至关重要。我们依靠它们在房屋和车辆中舒适，企业需要加热和冷却，以实现生产力的工作场所和工业流程。两者合计，空间和过程的供暖和冷却代表了对英国能源消耗的最大贡献，而温室气体排放的最大来源主要是由燃烧的天然气提供的，而冷却主要是由压缩挥发性荧光的气体提供的。但是，这些常规技术既不有效，也不对环境不友好。当受压力变化时，在机械响应固体中发生的可逆热变化是可逆的热变化。 These effects are analogous to the pressure-induced thermal changes in gases that are exploited in current heat pumps, but they promise higher energy efficiencies and obviate the need for harmful greenhouse gases.We aim at developing an energy-efficient barocaloric heat pump based on novel barocaloric hybrid composite materials that combine the best properties of organic barocaloric materials, namely extremely large pressure-driven thermal changes, and the best of inorganic突出材料，即高温导电性和低滞后作用。这种大小的技术转型将需要制定定制的经济和政策策略以成功地部署。因此，我们旨在制定一项完全集成的定制经济和政策战略，该战略将支持BC热泵通过商业化的创新。实现使用降压材料而不是气体运行的热泵的实现，将允许脱碳加热和冷却，提供能源独立性，并使英国能够成为这种新兴技术的世界领导者。
