Integrated Community Energy and Harvesting Systems (ICE-Harvest)

综合社区能源和收获系统是一个合作研究项目，为以社区为基础的热能和电能的使用和生产提供了一种创新的机制，大大减少了温室气体排放(GHG)。问题是，传统的天然气发电厂会产生“废”热；由于发热量与热需求之间的距离，燃料中高达60%-70%的能量被“损失”或“浪费”。拟议中的ICE-Heavest系统将在社区层面整合电力和热能生产，使社区能够获得天然气发电厂产生的热量，从而减少我们家庭需要燃烧的额外天然气的量。由于安大略省的供热需求如此之大(产生的二氧化碳排放量大约是电力的4倍)，因此有很大的机会大幅减少化石燃料的消耗，从而潜在地每年减少560万吨二氧化碳的碳足迹。ICE-Heavest系统在密集的混合使用地区附近以小规模(250千瓦-2兆瓦)发电，以满足当地的高峰需求(这些需求在一天、季节和一年中都会发生变化)，同时收集很大一部分“废弃”热能来供应当地的微型热网。ICE-GRAVEST是不同的，更适合安大略省和其他需要优先考虑热管理的寒冷地区，因此有能力更好地管理我们的能源需求，同时减少化石燃料消耗。它通过一种新的需求管理技术组合--热泵和吸收冷水机组--来管理对电力和热能的动态需求，并采用短期和季节性的储热方式，如地热法和相变法。这里提出的研究将创造独特的设计工具，使我们能够规划潜在地点的能源系统集成。这些工具将使用已经资助的麦克马斯特ICE-嘉实研究系统进行验证和演示；这一设施不仅在加拿大，而且在全球都是独一无二的。

Integrated Community Energy and Harvesting System (ICE-Harvest) is a cooperative research project that provides an innovative mechanism for community based integration of thermal and electrical energy use and production that significantly reduces greenhouse gas emissions (GHG). The problem is that traditional natural gas power plants produce "waste" heat; up to 60-70% of the energy in the fuel is "lost" or "wasted" due to the distance between heat generation and thermal demand. The proposed ICE-Harvest system will instead integrate electricity and heat production at the community level, so that communities will have access to this heat produced by natural gas power plants, decreasing the amount of extra natural gas required to be burned in our homes for heat. As the demand for heat in Ontario is so large (producing approximately 4 times the CO2 emissions of electricity), there is a great opportunity to significantly reduce fossil fuel consumption, thus potentially reducing our carbon footprint by 5.6 million tonnes of CO2 per year. The ICE-Harvest system generates electricity at a small-scale (250 kWe-2 MWe) near intensified, mixed-used areas in order to meet local peak demands (which change throughout the day, season, and year) while harvesting a significant portion of the "waste" thermal energy to supply local micro-thermal networks. ICE-Harvest is different and more appropriate for Ontario and other cold regions that need to prioritize heat management, and thus has the capability to better manage our energy needs while simultaneously reducing fossil fuel consumption. It does this through a novel combination of demand management technologies - heat pumps and absorption chillers to manage the dynamic demand for both electrical and thermal energy with both short-term and seasonal thermal storage, such as geothermal and phase change approaches. The research proposed herein will create unique design tools that will enable us to plan energy system integration for potential sites. The tools will be validated and demonstrated using the already funded McMaster ICE-Harvest Research System; a facility that is unique not only in Canada but globally.
