Solid State Thermal Battery
Project Innovation + Advantages:
The Antora Energy team will develop key components for a thermal energy storage system (solid state thermal battery) that stores thermal energy in inexpensive carbon blocks. To charge the battery, power from the grid will heat the blocks to temperatures exceeding 2000°C (3632°F) via resistive heating. To discharge energy, the hot blocks are exposed to thermophotovoltaics (TPV) panels that are similar to traditional solar panels but specifically designed to efficiently use the heat radiated by the blocks. The team will develop a thermophotovoltaic heat engine capable of efficiently and durably converting high-temperature heat into electricity. It will seek to double panel efficiency through new materials and smart system design, potentially enabling a cost effective grid storage solution.
Long-duration storage can help prevent blackouts and smooth overall grid operation, improving resilience and enhancing grid security.
New, extended storage options could enable greater integration of intermittent renewable energy sources, greatly reducing emissions from the power sector.
