The annual energy consumption is estimated to around 420 Million of TJ generating huge amount of heat. Most of this heat, in particular at low-medium temperature, is dissipated to the environment without being recovered. The main limitation and barrier is that the current solutions are not economically feasible; solid state thermoelectric devices are the only technologies available to recover low grade heat, however, not yet cost-effective due to the large amounts of rare and expensive materials used and their very low energy conversion efficiencies. Key objectives of EHAWEDRY’s technology are: – Utilization of Abundant, Low-Cost Materials: By using materials that are readily available and inexpensive, the technology ensures cost-effective production and scalability. – Reduction of Conversion Process Costs: The innovative use of electrochemical capacitors, instead of complex mechanical systems, significantly lowers the costs associated with the energy conversion process. This makes the technology more economically viable. – Enhanced Design Flexibility: The absence of mechanical components allows for a more flexible and adaptable design. This flexibility means the technology can be tailored to a wide range of applications and easily integrated into various systems. Through this innovative approach, which allows a more feasible waste heat recovery, EHAWEDRY, will broadens the range of potential applications, enhancing the market scalability of thermoelectric devices.
