100% Solar energy run Cold Storage (SolCoS)

SolCoS项目由两个英国行业Solar Polar和CoolSky、一个肯尼亚行业Kijani和一所英国大学伦敦布鲁内尔大学（BUL）合作，旨在为肯尼亚小农户的园艺产品提供一个创新的冷藏库。SolCoS冷库将包括三个创新的新功能-（i）紧凑，模块化的热运行（200- 250 ℃）扩散吸收式制冷机（DAR），能够在13 ℃下提供制冷空间，COP>0.7;（ii）专门开发的聚光太阳能技术，以利用肯尼亚巨大的太阳能资源供应所需的热能和电能，以及真空绝缘，以实现<0.25 W/m2 K的存储水平U值。该项目将展示用于香蕉水果的SolCoS技术，尽管任何园艺产品都可以使用它来保存。最大限度地减少园艺产品的损失和浪费可以有效地减少生产所需的面积和/或增加粮食供应。在肯尼亚，由于缺乏储存设施，大约25-45%的香蕉果实损失，给40万农民（其中大多数是妇女）和50万分部门雇员造成经济损失。一定比例的营养损失是可以理解的。SolCoS技术被认为是一种具有成本效益和技术可行性的解决方案，因为它提出了最大限度地提高肯尼亚高太阳能资源的价值，允许农业工业发展而不影响网络电力，因此不会阻碍肯尼亚到2030年实现每户家庭用电的电气化目标;目前的比率为75%。SolCoS项目将在Kijani位于基苏穆的测试场地设计、制造和安装一个原型，包括配备模块化扩散吸收式制冷机和太阳能集中器的真空板隔热冷藏库。在基苏穆的成功示范将使SolCoS冷藏技术能够推广到所有主要的香蕉生产集群和市场，为90万小农和小企业提供直接的经济利益。这样保存下来的香蕉果实将为数百万人提供营养。此外，这笔赠款将为非洲和全球香蕉业的太阳能热技术提供机会，从而发展英国的太阳能业务。尽管非洲拥有世界上最丰富的太阳能资源，但仅安装了5吉瓦（GW）的太阳能发电，不到全球装机容量的1%，工业过程的太阳能热量几乎为零。

The collaborative SolCoS project among two UK industries Solar Polar and CoolSky, one Kenyan industry, Kijani and one UK university, Brunel University London (BUL), aims to deliver a radically innovative cold storage for horticultural produce of smallholders of Kenya. SolCoS cold storage will comprise of three innovative novel features -- (i) a compact, modular heat run (200-250C) diffusion absorption chiller (DAR) able to deliver a chilled space at 13 C at COP of \>0.7; (ii) a specially developed concentrating solar technology to harness Kenya's vast solar resource supply heating and electrical energy required and (iii) vacuum insulation to achieve a storage level U-value of <0.25 W/m2K. The project will demonstrate the SolCoS technology for banana fruit, though any horticulture produce could be preserved using it. Minimising loss and waste of horticultural products can effectively reduce the area needed for production and/or increase food availability. In Kenya, about 25-45% of Banana fruit is lost due to lack of storage facilities causing economic loss to 400,000 farmers, majority of whom are women, and 500,000 subsector employees. A nutrition loss of a proportionate amount can be comprehended. The solar run cold storage SolCoS technology is proposed as a cost-effective and technologically viable solution because it proposes to maximise the value of high solar resource of Kenya allowing agro-industrial development without biting into network electricity, thus without hindering Kenya's electrification target of reaching power to every household by 2030; current rate is 75%. SolCoS project will design, manufacture and install a prototype comprising vacuum panel insulated cold storage equipped with modular Diffusion absorption chillers and solar concentrator at Kijani's testing site at Kisumu. A successful demonstration at Kisumu will enable rolling out the SolCoS cold storage technology to all major banana production clusters and markets providing a direct route to pass economic benefits to 900,000 smallholders and small businesses. Banana fruit thus saved will deliver nutrition to millions. Additionally, this grant will unleash an opportunity for solar heat technology in African and global banana industry, growing UK's solar energy business. Africa despite the richest solar resources in the world, has installed only 5 gigawatts (GW) of solar power, less than 1% of the global installed capacity, and nearly zero solar heat for industrial processes.
