Development of a zero-carbon power generator for construction sites

建筑工地的脱碳是非常具有挑战性的。电网连接经常不可用，因此，化石燃料被用来为发电机和设备供电。这个项目将评估一种通过使用绿色氨(NH3)作为现场发电的能源来实现脱碳和减少与化石燃料相关的其他排放的方法。绿色氨正在变得可用，可以低成本地在世界各地运输，并且很容易用卡车运送到建筑工地，无论它们在哪里。氨本身燃烧得不够好，不足以在现有的发电机中使用，但当与少量氢气混合时，据广泛报道，一些混合物可以燃烧，性质接近化石燃料。Catalsys开发了一种新的、高效的技术来生产氨/氢混合物。研究表明，这种混合物可以用于传统的、未经改造的天然气发动机发电机。该项目将研究这一假设的实际实施情况。该产品的成功开发将为建筑工地运营商提供一种商业上可行的选择，用于为公用事业和电动汽车充电提供现场电力。Catalsys技术能够通过利用发动机排气产生的热量来提供生产氨/氢混合物所需的所有能源，从而实现高效率。它可以完全独立于任何外部电网基础设施运行，并可以在站点之间轻松运输。Catalsys将与布鲁内尔大学合作，优化各种发动机类型所需的燃料组合和发动机控制参数，该项目将生产出与商业天然气发动机发电机集成的原型。英国一家大型建筑公司Skanska将在一个建筑工地上进行一项受控实验，以提供技术验证。发电机将用于为不同类型的设备提供电力，将在不同的负载条件下进行测试，并将由工厂运营商评估其易用性。将对发电机的运行和氨燃料在真实地点储存所需的法规和许可进行详细评估。还将进行全面的安全和可操作性分析，以确定在进一步商业开发之前需要进行的修改和改进。

The decarbonisation of construction sites is very challenging. An electrical grid connection is often not available and consequently, fossil fuels are used to power generators and equipment. This project will evaluate a means of achieving decarbonisation and reducing other emissions associated with fossil fuels by using green ammonia (NH3) as an energy source for on-site power generation.Green ammonia is becoming available and can be transported around the world at low cost, and easily delivered by truck to construction sites, wherever they may be.On its own, ammonia does not burn well enough for use in existing generators but when mixed with a small amount of hydrogen, it is widely reported that some mixtures can burn with properties close to those of fossil fuels.Catalsys has developed a novel, high efficiency technology to produce ammonia/hydrogen mixes. Research indicates that such mixes could be used in conventional, unmodified natural gas engine generators. This project will investigate the practical implementation of this hypothesis.Successful development of this product will provide construction site operators with a commercially viable option for the production of on-site power for utilities and electric vehicle recharging.Catalsys technology is able to achieve high efficiency by using the heat from the engine's exhaust to provide all of the energy required for the production of the ammonia/hydrogen mixture. It can operate totally independently of any external grid infrastructure and can be easily transported between sites.Catalsys will work with Brunel University to optimise the fuel mix and engine control parameters needed by various engine types and the project will produce a prototype integrated with a commercial natural gas engine generator. Skanska, a major UK construction firm, will host this in a controlled experiment on a construction site to provide a technology validation. The generator will be used to provide power for different types of equipment, will be tested under varying load conditions and will be assessed by plant operators for its ease of use.A detailed assessment will be made of the regulations and permissions required for the operation of the generator and the storage of ammonia fuel on a real-world site. A comprehensive safety and operability analysis will also be performed to identify modifications and improvements required before further commercial development.
