Experimental Development of a Zero Carbon Boiler to a stage where it can deployed in real homes with beta customers

Caldera是一家蓄热公司，希望通过解决电网规模问题来实现经济脱碳。英国政府希望通过“重建更好的"绿色经济来应对新冠肺炎对经济的影响，这将直接实现政府的清洁增长战略和净零碳目标。Caldera开发了一种零碳锅炉，它从电网中获取可再生电力，并将其转化为热量，储存在机组中，直到消费者需要供暖或热水。Warmstone技术将增加可有效利用的可再生能源的数量，从而降低可再生能源的成本。为了使这项技术更接近现实，该设备需要开发到一个可以在家庭中安全部署和测试的程度。零碳锅炉内部有一个创新的核心，商标为“Warmstone”技术。Warmstone技术是一种低成本的存储介质，能够吸收可再生电力，并为一个4居室的家庭存储相当于冬季最冷的一天24小时或夏季7天热水的能量。零碳锅炉是一个圆柱形的锅炉，重1.5吨，直径1米，高1.6米。该单位将位于外部的财产或在车库或厂房。现有的锅炉被拆除，并更换为热接口单元。热接口单元是大规模生产的，因为它们用于区域供热网络，将热量从网络转移到个人家庭。使用标准的热接口单元意味着这项技术是一种直接的改造，可以由管道工进行，而无需额外的培训或对物业进行修改。热接口单元通过两个绝缘管道连接到零碳锅炉。零碳锅炉还连接到家庭的主要电力供应。迄今为止，Cadera位于Fareham的生产设施已经建造并测试了半个尺寸的设备，并准备在今年9月（2020年）部署到测试室。当新装置安装并在测试室中运行时，它将处于技术就绪等级5（2020年9月）。该项目将把技术就绪等级5的装置发展到技术就绪等级6，以便它可以在2021年夏季安全地安装在真实的家庭中，并在接下来的冬季进行试验。该项目将包括制造两个装置，一个用于认证测试，另一个安装在Fareham的Caldera设施进行试验。

Caldera is a heat storage company looking to decarbonise the economy by solving grid scale problems. The UK government is looking to tackle the economic impact of Covid-19 by 'building back better' a green economy that will deliver directly on the government's Clean Growth Strategy and net zero carbon ambition.Caldera has developed a Zero Carbon Boiler which takes renewable electricity from the grid and converts it into heat which is stored within the unit until the consumer wants heating or hot water. The Warmstone technology will increase the amount of renewable energy that can be productively used, which in turn keeps down the cost of renewable energy. To bring this technology a step closer to reality, the unit needs to be developed to a point where it is safe to deploy and test in a domestic home.The Zero Carbon Boiler has an innovative core inside that is trademarked as "Warmstone" Technology. The Warmstone technology is a low cost storage media that is able to absorb renewable electricity and store the equivalent energy for a 4 bedroom home to cover a 24 hour period on the coldest winter day or seven days of hot water in the summer. The energy is retained with 5-10% losses per day with an efficient insulation strategy.The Zero Carbon Boiler is cylindrical in shape, weighs 1.5 tonnes and is 1m in diameter by 1.6m tall. The unit will be located externally to the property or in a garage or plant room. The existing boiler is removed and replaced with a Heat Interface Unit. Heat Interface Units are mass produced as they are used in district heating networks to transfer heat from the network to individual homes. The use of a standard Heat Interface Unit means that this technology is a straight forward retrofit and can be carried out by a plumber without additional training or modification to the property. The Heat Interface Unit is connected to the Zero Carbon Boiler via two insulated pipes. The Zero Carbon Boiler is also connected to the main electricity supply to the home.To date a half size unit has been built and tested in Cadera's production facility in Fareham, with a full size unit in manufacture ready for deployment to a test house in September this year (2020). When the new unit has been installed and is functioning in the test house it will be at Technology Readiness Level 5 (September 2020).This project will develop the Technology Readiness Level 5 unit to a Technology Readiness Level 6 status so that it can be safely fitted in real homes in summer 2021 for trials over the following winter. The project will include the manufacture of two units with one being used for certification testing and the other installed for trials at the Caldera facility in Fareham.
