“…The utilization of the cold energy (or both the power and cold energy) associated with these clean fuels can recover part of the cost of liquefying or compression and thus promote the application of these fuels. To the best of our knowledge, previous studies have usually used such cold energy for cooling [14][15][16] , or utilized the temperature difference between the environment and the cold energy resources to generate power [15][16][17][18] ; in contrast, we propose for the first time a simple and general approach to utilizing this temperature difference to supply heat. A considerable proportion of these fuels are exactly used to supply heat, in this case the application of HC-2s can bring significant benefits-consuming equal fuel to supply more heat, or consuming less fuel to supply equal heat.…”

Considering the significance of thermodynamic cycles in the global energy system, it is necessary to develop new general classes of thermodynamic cycles to relieve current energy and environmental problems. Inspired by the relationship between power cycles and refrigeration cycles, we realize that general classes of thermodynamic cycles should occur in pairs with opposite functions. Here we reverse class 1 heating cycles to obtain another new general class of thermodynamic cycles named class 2 heating cycles (HC-2s). HC-2s have two basic forms, and each contains six thermodynamic processes. HC-2s present the simplest and most general approach to utilizing the temperature difference between a medium-temperature heat source and a low-temperature heat sink to achieve efficient high-temperature heating. HC-2s fill the gaps that have existed since the origin of thermal science, and they will play significant roles in the global sustainable energy system.

“…Biomass energy has been gradually substituted after the discovery of huge quantities of cheap fossil fuels, which proved to be more convenient for daily use and transport purposes (Thornley 2006 ) . The use of biomass energy on a large scale has been considered a promising option, which could contribute to sustainable development in the environmental, social and economic sectors (Trevisani et al 2007 ;Serrano-Ruiz et al 2010 ) .…”

“…Due to the lack of large application, little research have focused on the cold energy utilization of LH 2 . Trevisani et al proposed and compared gas turbine and magnetohydrodynamics based energy recovery systems that produce electric energy [12]. Zhang et al established a novel Brayton cycle with the integration of LH 2 cryogenic exergy utilization, which can reach high energy and exergy efficiency (73% and 45%, respectively) [13].…”

In this paper, a kind of on-board liquid hydrogen (LH2) cold energy utilization system for a heavy-duty fuel cell hybrid truck is proposed. Through this system, the cold energy of LH2 is used for cooling the inlet air of a compressor and the coolant of the accessories cooling system, sequentially, to reduce the parasitic power, including the air compressor, water pump, and radiator fan power. To estimate the cold energy utilization ratio and parasitic power saving capabilities of this system, a model based on AMESim software was established and simulated under different ambient temperatures and fuel cell stack loads. The simulation results show that cold energy utilization ratio can keep at a high level except under extremely low ambient temperature and light load. Compared to the original LH2 system without cold energy utilization, the total parasitic power consumption can be saved by up to 15% (namely 1.8 kW).
