Home refuelling unit for CNG cars and vans

使用压缩天然气(CNG)作为道路燃料是一项成熟的技术，目前全球有超过1200万辆汽车使用CNG作为道路燃料。使用CNG可以减少车辆排放，减少二氧化碳排放，降低燃料成本，并被视为一种从石油转向多元化的方式。甲烷的非化石来源生物甲烷也可以作为天然气的来源。与所有替代燃料一样，CNG市场的增长可能会受到加油基础设施创建速度的限制，导致CNG的潜在用户变得沮丧。为了帮助克服这一点，GasFill Limited的愿景是开发并向市场推出一种低成本、易于安装、低维护的缓慢填充CNG加油装置，可以在世界任何地方使用。目标市场被视为国内市场。加斯加仑开发了一种创新的三级无油压缩机，使用正常的单相电源，天然气可以从国内供应管道压力21mbar到车载储存压力200bar。该压缩机已在英国获得专利，在美国和欧洲的专利申请进展顺利。该压缩机已用于概念验证技术演示CNG加油装置，以获得寿命性能数据和潜在用户的反馈。基于这一反馈，已经制定了一种适合国内市场的加油装置的成本和性能规范。该项目的目的是开发一种符合该规范的“接近市场”的原型，用于在投放市场之前对试生产单元进行详尽的测试、可制造性和坚固性评估。预计该项目将产生一种用于CNG汽车的缓慢填充的家用加油装置，将有可能在全球范围内大量销售。

The use of CNG (compressed natural gas) as a road fuel is a well established technology andthere are now over 12 million vehicles worldwide using CNG as a road fuel.The use of CNG results in lower vehicle emissions, less CO2 impact, reduced fuel costs andis seen as a way of diversifying away from oil. Biomethane, a ‘non fossil’ source of methanecan also be used as the source for the CNG.As with all alternative fuels, the growth of the CNG market can be constrained by the rate atwhich the refuelling infrastructure is created leading to potential users of CNG becomingfrustrated.To help overcome this, gasfill Limited’s vision is to develop and bring to market a low cost,easy to install, low maintenance slow fill CNG refuelling unit that can be used anywhere inthe world. The target market is seen as the domestic market.gasfill have developed an innovative 3 stage oil less compressor that allows natural gas to becompressed from the domestic supply line pressure of 21mbar up to the on vehicle storagepressure of 200bar using a normal single phase electrical supply. This compressor has beenpatented in the UK and patent applications in the USA and Europe are .well advanced.The compressor has been used in a proof of concept technology demonstrator CNG refuellingunit to obtain lifetime performance data and to obtain feedback from potential users. Based onthis feedback a cost and performance specification for a refuelling unit suitable for thedomestic market has been developed.The aim of this project is to develop a ‘near market’ prototype which meets the specificationand which will be used to facilitate exhaustive testing, manufacturability and robustnessassessment required of a pre production unit prior to market launch.It is anticipated that the project will result in a slow fill home refuelling unit for CNG vehiclesthat will have the potential for high volume sales worldwide.
