Net Zero carbon in the Dairy Supply Chain - Innovative Productive Use of Energy Products

实现净零碳排放是全球范围内的当务之急，英国政府正在率先制定雄心勃勃的目标，并资助开发新技术、产品和服务，以在全球范围内出口这一能力，促进我们的经济、就业和出口。该项目将为发展中国家的牛奶行业开发无电池的离网太阳能制冷能力，在这些国家，腐败，浪费，效率低下，不可靠的柴油发电机是常态。太阳能电池板的价格正在迅速下降，但逆变器和电池的成本是静态的，占一些太阳能项目成本的50%以上。通过改进绝缘和（相变）材料，用冷存储代替电池，降低了成本。直流压缩机提高了效率，消除了逆变器。太阳能是可扩展的，使小型小型制冷机和绝缘（相变）牛奶搅拌器可行，减少牛奶浪费，提高质量，同时增加牛奶收集半径。这反过来又会增加农民的数量和进入更高价值牛奶加工链的牛奶数量，这将推动规模经济，并为23%的5岁以下儿童营养不良和发育不良的国家提供更多的营养。坦桑尼亚和乌干达的奶制品是重要的出口产品，2016-2018年翻了一番，达到每年1.3亿美元。

Reaching net-zero-carbon emissions is a world-wide imperative and the UK Government is taking the lead by setting ambitious targets and funding the development of new technologies, products and services to export this capability worldwide, enhancing our economy, jobs and exports. This project will develop off-grid solar refrigeration capability without batteries, for the milk industries in developing countries where spoilage, wastage, inefficient, unreliable diesel generators are the norm. Solar panel prices are falling rapidly, but inverter and battery costs are static accounting for \>50% of the costs in some solar projects. Replacing batteries with cold storage through improved insulation and (phase-change) materials, reduces costs. DC compressors improve efficiencies and eliminate inverters. Solar is scalable, making small small-holder chillers and insulated (phase-change) milk churns viable reducing milk wastage and improving quality whilst increasing the radius of milk collection. This will, in turn, increase the number of farmers and volume of milk feeding into the higher value milk processing chain, which will drive economies of scale and provide increased nutrition in countries were 23% of under 5's are malnourished and stunted. Milk products in Tanzania and Uganda are an important export, doubling in 2016-2018 to $130m per annum.
