The federal grant notice titled "Grid-free Renewable Energy Enabling New Ways to Economical Liquids and Long-term Storage SBIR/STTR (GREENWELLS SBIR/STTR)" is being offered by the Advanced Research Projects Agency Energy (ARPA-E). This grant opportunity is aimed at producing sustainable carbon-containing liquids from renewable energy and carbon dioxide (CO2) by developing dynamically operable reactor systems that can utilize cheap, intermittent energy sources such as wind and solar.
The purpose of this grant is to address the challenges in interconnecting renewable energy projects to the electric grid. Currently, the wait times for wind and solar projects from interconnection request to operation can take up to four years. This grant aims to find a method to use renewable energy without grid interconnection, which can accelerate the deployment of renewable energy and provide cost-effective energy carriers for long- and medium-term energy storage.
Additionally, this grant seeks to develop technological solutions for transportation sectors, such as aviation, marine, and heavy-duty vehicles, to lower their emissions. Alternative fuels and power trains are being explored for these sectors, and low-carbon fuels derived from power-to-liquids (PtL) processes are being considered. However, the current cost of sustainable aviation fuel (SAF) derived from PtL processes is around $10 per gallon (gal). This grant aims to reduce costs by minimizing high capital expenditure units and utilizing cheaper electricity sources like wind and solar power with no connection to the grid.
The primary objective of the GREENWELLS program is to develop chemical reactors and supporting units that can economically store at least 50% of incoming intermittent electrical energy in carbon-containing liquids. The program expects that these reactors will need to be dynamically operable to optimize the entire system of renewable energy production, electrolysis capital, and energy storage. Various technical process approaches, such as thermal, electrochemical, plasmonic, photonic, and biological, are expected to be explored to address this problem.
Successful projects under this grant will provide low-cost carbon-containing liquids that enable the transportation and storage of renewable energy. These liquids should be suitable for use in the difficult-to-decarbonize sectors and contribute to reducing energy-related emissions and imports of energy from foreign sources. The deadline for submissions to this grant is April 18, 2024, at 9:30 a.m. Eastern Time.
