Combined Energies Novel Power Electronics for Distributed Generation and Energy Storage Applications Hydrogen+Batteries+Fuel Cell Exhibit Hannover Messe 2018 Efficient by design.
Company Overview • Combined Energies is a product development and manufacturing startup located in upstate New York, USA, focused on providing power electronics for the clean technology market. • Formed in 2011, the founders were pursuing residential CHP fuel cells. Lacking investment interest, the company pivoted to pursue the development of a DC-DC power converter technology specifically for fuel cells. Recently we’ve expanded our interests to include renewables, energy storage and fuel cell range extenders. • Combined Energies was granted at US Patent 9,413,271 for our high boost, bi-directional converter and was recently granted U.S. Patent 9,906,039 which claims our high boost converter with multiple DC inputs. An EU patent has been filed.
Combined Energies in the News • April 2018 CE receives $501K grant from New York State Energy Research and Development Authority (NYSERDA) to fund commercial design of DC to DC Converter • February 2018 CE receives Global New York State Trade Expansion Program (STEP) Grant Award to attend Hannover Messe 2018 trade show. • January 2018 CE was accepted into the Clean Energy Incubator at RIT Venture Creations in Rochester, New York USA
Our Product: The Marathon LR Motivation: There is a need for power electronics that efficiently and cost effectively convert variable, low voltage DC power into steady, high voltage DC. Electrochemical device (fuel cell) example 0.75 End of life with Typical voltage current DC to DC degradation curve converters 0.70 Cell Voltage Minimum voltage for 0.65 inverter operation Area of increased Increased 0.60 energy recovery voltage range Life increase with Marathon LR 0.55 Life
Industries that Benefit Variable Low Voltage Input Bi-Directional High Efficiency > 10:1 Boost
The Marathon LR- Efficient by design. Solution: Combines Gallium Nitride (GaN) FETs, high current, DC boost topology with a transformer stage to create a single power conversion device that provides: • Greater than 10:1 boost ratio • High efficiency (>95%) at very low voltages • No active cooling requirements • Bi-directional or uni- directional operation • Grid isolation 10kW building blocks- 3.3kW X 3
New York State Energy Research and Development Authority • Award is $501K with a 50% cost share • Funds development of a DC-DC for three different applications • Contracted with Vanteon Electronic Design in Rochester, NY. • Three project partners – Sunfire GmbH- SOFC fuel cells and electrolyzers – Ducted Turbines International – small wind – Fuel cell range extender • Customized packaging based on the application • Available in late 2018 10kW X 3
