Molecular dynamics simulations elucidate the essential role of strong interaction between water molecules and polymer chains in generating the negative pressure. With such a large negative pressure, we demonstrate a streaming potential generator that spontaneously converts environmental energy into electricity and outputs a voltage of 1.06 V.
To address these issues, a power generation system for pressure energy recovery at natural gas city gate stations is proposed and investigated. Firstly, the post-heating method is adopted and turboexpander is employed to convert the pressure energy into electricity.
Under design conditions, the system energy and exergy efficiencies reach 42.54% and 88.77%, while the energy recovery rate is 88.11% in high pressure mode. Parameter sensitivity analysis implies that the increase of NG inlet pressure has a positive effect on ERR, but a negative effect on system energy and exergy efficiencies.
By using the negative pressure, we fabricated a streaming potential generator that spontaneously converts environmental heat energy into electricity and outputs a voltage of 1.06. Moreover, we proposed and demonstrated “negative pressure heat pipe” for the first time, achieving a high heat transfer density of 11.2 kW cm–2 with a flow length of 1 m.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
