“…The use of a Stirling engine for heat recovery was studied by (Güven, Bedir, & Anlaç, 2019) with 30% additional useful energy generation when used with an internal combustion engine. Figure 10 shows the relationship between the power generated and the temperature of the hot cylinder of the Stirling engine.…”

The use of adsorption in Thermal Energy Storage has gained considerable research interest of late. Some applications have focused on the use of TES for transformation of low temperature heat in applications such as cooling and heating. Zeolite and water have been studied as suitable materials. Their characteristics as environmentally friendly materials and high affinity makes them conspicuous. The unique properties of zeolites to hold adsorbed water/heat with very minimal loss is also significant. With the aid of a dynamo, a Stirling engine as heat engine and the adsorption energy storage system serving as heat pump was used to generate electricity. The relationship between electricity generation and temperature was investigated. The obtained average temperature and pressure of the zeolite - water adsorption heat pump was also compared with the basic adsorption cycle.

“…Notably, using Stirling engines to tap into the energy of waste heat is promising because the majority of the primary energy has been dissipated into the environment during a variety of energy conversion processes (LLNL 18 ). Guven et al 19 reported a study of employing Stirling engines to recover waste heat in the exhaust gases of a heavy‐duty truck's diesel engine. They concluded that a β ‐type engine would be more effective for this task than an α ‐ or a γ ‐type.…”

Despite the fast advance of modern technology, poverty is still a serious problem in many developing countries; and more than 1 billion people are having no access to electricity. For these people, even a few Watts of electricity supply for lighting can make a big difference. In this study, a simple, compact, unpressurized, Watt-level low-temperature-differential Stirling engine has been developed aiming to solve the lighting problem in developing countries. The engine in this study is compact. Yet, it is capable of delivering useful electrical power. It is a γ-type Stirling engine with twin power pistons. The diameter of the displacer cylinder is 220 mm, comparable to the size of a cooking pot, and the weight of the engine is under 5 kg. Two energy-conservation/ heat-transfer enhancement measures have been incorporated into the engine's design: one is adopting a displacer/regenerator unit, and the other is machining engine-turn slotted grooves on its hot-and cold-end plates. CFD analysis showed that the combination of both measures could effectively improve the performance of the engine. Experiments were conducted to examine the engine's performance. In one experiment, the engine produced 3.7 W of electric power as temperature difference was 100 C, and its power was found to be almost linearly proportional to temperature difference. With a higher temperature difference of 140 C, the electric power reached 5.3 W. Another experiment that operated the engine for a prolonged period has proven the reliability of the engine's performance for long-time use. In practice, the engine can be operated by putting it on a stove table, and the residual heat from cooking is good enough to power the engine to produce usable electricity. Or it can be directly put on a wood fire to generate even higher electrical power.

Waste Heat to Power: Technologies, Current Applications, and Future Potential

Energy consumption, environmental impact, and sustainability have risen fast through the ranks, achieving the first places in driving investments, policies, and concerns of all countries at any developmental stage. Energy transformation, though, must cope with nonunitary efficiency of devices and processes, which results in a distributed production of waste heat. A reduction of emissions, implying a conversion of waste heat to more noble forms of energy and a concurrent increase in efficiency of the same devices and processes, is of paramount importance. In view of the enthalpy content and distribution of the different sources of waste heat, low‐grade/low‐enthalpy sources below 200 °C are considered the most fertile field for research and development, with an impressive industrial growth rate. Thermodynamic cycles and thermal conversion devices based on the most relevant physical effects are herein introduced and briefly described, including both solutions that already achieved industrial maturity and less developed systems and devices whose study is still in progress. A specific focus on three application domains, selected due to their economic relevance, is done: industrial processes for the vast energy and capital availability, automotive sector for its permeation, and wearable devices for the market size. Limits and opportunities are critically discussed.
