Technology Description:

Chemtronergy will develop an advanced solid oxide fuel cell (SOFC) system to electrochemically convert ammonia into electricity. Conventional SOFC systems are manufactured using ceramic fabrication techniques that are time-consuming, energy-intensive, and have high material costs. SOFCs also typically operate at 700-900°C to chemically activate the fuel feedstock and ensure that it is sufficiently cracked or reformed for electrochemical use. This high temperature, however, imposes harsh operating conditions and stresses on the materials, which further increases costs. To address these challenges, the team proposes to lower the operating temperature below 650°C and to develop anode, cathode, and electrolyte materials using a combination of advanced materials discovery, reaction kinetics modeling, and 3D printing technology for large-scale rapid prototyping. The team hopes to greatly reduce the cost of SOFC systems while providing a distributed power-generating option with high efficiency, long life, and a reduced carbon footprint.

Potential Impact:

If successful, developments from REFUEL projects will enable energy generated from domestic, renewable resources to increase fuel diversity in the transportation sector in a cost-effective and efficient way.

Security:

The U.S. transportation sector is heavily dependent on petroleum for its energy. Increasing the diversity of energy-dense liquid fuels would bolster energy security and help reduce energy imports.

Environment:

Liquid fuels created using energy from renewable resources are carbon-neutral, helping reduce transportation sector emissions.

Economy:

Fuel diversity reduces exposure to price volatility. By storing energy in hydrogen-rich liquid fuels instead of pure hydrogen in liquid or gaseous form, transportation costs can be greatly reduced, helping make CNLFs cost-competitive with traditional fuels.
