SuperCharGen

Challenge

The global challenge of Electric Vehicles (EV) deployment represents an exciting opportunity for Samad Power from the emerging transport electrification and decarbonisation.
National Grid’s “Future Energy Scenarios” report shows over 11 million cars in the UK are going to be electric by 2030 accounting for an additional 22TWh electricity consumption. The generation and management of the peaks of power demand will be challenging with today’s system.

Our Proposal

To address the latency of demand for EV charging infrastructure, Samad Power intends to explore the use of off-the-shelf gas turbine engines from established OEMs in a high-power EV charging setup, with a view to switch to hydrogen as a zero carbon fuel when it becomes abundantly available.
This turbo-generator, called ‘SuperCharGen’ provides complementary power source for a small number of rapid chargers as well as larger array of slower chargers. The proposed innovative solution tackles the issue of power access and transmission loss as well as the fast charging infrastructure needed to facilitate EV deployment.
SuperCharGen is in line with UK Government’s Clean Growth Strategy vision and addresses “decarbonising energy, business and industry” and “accelerating the shift to low carbon transport” themes.

Innovation Features

Variable speed GT engine with single rotating shaft and direct drive system to achieve high power density.

 

  • Variable speed GT engine with single rotating shaft and direct drive system to achieve high power density.
  • Integrated hybrid power storage system to allow fast charge and discharge.
  • Smart power management strategy (PMS) to satisfy the demand from EV chargers, local building and Demand Side Response (DSR) event to increase usage factor.
  • Two-way communication and a multi-objective optimisation algorithm capable of efficiently managing the energy flows (50kW to 350kW) to provide dynamically optimal charging profiles for each EV, while prolonging the lifetime of battery systems.
  • Efficient hydrogen micromix combustor to achieve zero CO2 and ultra-low NOx emissions.

 

SuperCharGen will in future take advantage of the growing supply of renewable hydrogen including local renewable hydrogen generation. It is aiming for ~41% electrical efficiency and up to 90% overall energy efficiency in CHP mode.

Market

En-route rapid chargers need to increase by 20X from about 800 in 2019 to 16,000 by 2030 to keep up with demand (Delta-EE). The National Grid is developing plans to install a network of fifty 350 kW superfast charging points along Britain’s motorways. However, the requirement for ‘top-up’ charging is expected to increase 10X from 2,700 in 2016 to 27,000 by 2030 (CCC Report, 2018), with a potential market value of £3 billion. The EU market is worth £20 billion and £117.5 billion globally (~200k units).
The initial target market for our solution is 4,000 supermarkets sized over 1,000 square meter in the UK (UK Supermarket Chain Profiles by GAIN), followed by introduction to service stations, shopping malls, hotels, airports, leisure facilities (over 40,000). UK supermarkets regard charging points as a green strategy to maintain in-store footfall. Approximately 97% UK supermarkets have an unmet need for EV charging service (Emu Analytics, 2018).
