本研究采用ECLIPSE模拟软件，研究了一个家庭规模的三联产柴油发电机的基础上与氢相比，单代，热电联产的性能和排放特性。在单代模拟中，发动机发电机组仅用于发电，发动机的热量被排放到大气中。在热电联产和三联产中，除了发电机组产生的电力外，热废气和发动机冷却系统排出的废热通过热交换器和热水箱被捕获用于生活热水供应;并且部分废热用于驱动三联产中的吸收式冷却。对这三种工况下的模拟结果进行了比较。结果证明，氢气是未来潜在的能源载体，是满足即将到来的严格温室气体排放的关键。研究表明，氢气具有很好的前景，可以在能量性能方面实现比传统柴油更好或等同的性能，并且碳排放接近零，这取决于氢气生产方式的生命周期分析。研究结果还表明，与单一发电相比，热电联产和三联产具有巨大的潜在燃料节约潜力，每单位有用能源产出的温室气体排放量也大幅减少。
This study examined the performance and emission characteristics of a household size trigeneration based on a diesel engine generator fuelled with hydrogen comparing to that of single generation, cogeneration using ECLIPSE simulation software. In single generation simulation, the engine genset is used to produce electricity only and the heat from the engine is rejected to the atmosphere. In cogeneration and trigeneration, in addition to the electricity generated from the genset, the waste heat rejected from the hot exhaust gases and engine cooling system, is captured for domestic hot water supply using heat exchangers and hot water tank; and a part of the waste heat is used to drive absorption cooling in trigeneration. Comparisons have been made for the simulated results of these three modes of operation for hydrogen and diesel. The results prove that hydrogen is a potential energy vector in the future which is a key to meeting upcoming stringent greenhouse gases emissions. The study show that hydrogen has very good prospects to achieve a better or equal performance to conventional diesel fuel in terms of energetic performance, and a near zero carbon emission, depending on the life cycle analysis of the way the hydrogen is produced. The results also show enormous potential fuel savings and massive reductions in greenhouse gas emissions per unit of useful energy outputs with cogeneration and trigeneration compared with that of single generation.
