ElectraTherm selected for US$1.4 million Cooperative Agreement from US DOE

In the United States (US), waste heat to power (WHP) technology provider ElectraTherm Inc., has announced it was selected by the US Department of Energy (DOE) for approximately US$1.4 million towards a cooperative agreement, estimated to begin October 1, 2018. The milestone-based funding, supporting several years of research and development, will enhance reciprocating engine based combined heat and power (CHP) systems via integrated waste heat to power Organic Rankine Cycle (ORC) technology.

ElectraTherm utilizes Organic Rankine Cycle (ORC) and proprietary technologies to generate power from low-temperature heat ranging from 77-122°C (170-252°F). Hot water is the only “fuel” consumed by its “Power+ Generator”.

According to ElectraTherm, the project will help accelerate the development of a high-temperature ORC generation unit to provide additional power when needed by the grid, while also maintaining useful thermal energy for combined heat and power (CHP) applications.

The ORC developed under this project will overcome the current limitation of useful thermal energy after the bottoming cycle by driving the current input temperature limits listed above towards 149°C (300°F) and available heat after power production to the 82°C (180°F)  range.

According to the DOE, CHP systems “can provide utilities and grid operators with a cost-effective way to obtain the grid services they need to stabilize the electric power system and keep it running. CHP can also help improve the resiliency of the US electric grid by providing supplemental power during natural disasters, and help reduce the strain on existing grid infrastructure by meeting peak demand, reducing congestion, and improving overall power quality. In addition, these systems can also provide facility owners with more efficient and lower cost electricity.”

We look forward to working with the Department of Energy on the optimization of ORC technology for CHP systems. This will be our second project with the DOE and their past support leads us to the successful commercialization of micro-geothermal systems. We look forward to working together on increasing CHP implementation nationwide at small-to-midsize facilities that could tremendously benefit from flexible, cost-effective power, said John Fox, Managing Director of ElectraTherm.
