The Canadian fuel cell innovator has revealed details of its new S1200 system which it says builds on its existing technology, providing an additional 20% in efficiency, reaching up to 60% net system efficiency, compared to 44% typical fuel efficiency of a diesel engine.

When integrated into an electric vehicle, Loop says the fuel cell can deliver up to 54% fuel to wheel efficiency, compared to the typical fuel to wheel efficiency of a diesel engine at 20-25%.

Incorporating Loop’s patented eFlow™ fuel cell architecture, the fuel cell features trapezoid plates with narrowing channels for its bipolar plates, which the company says increases gas velocity, delivering superb performance for fuel efficiency and power output.

It is hoped the development will significantly impact commercial vehicle manufacturers, fleet operators and associated industries, as well as the global clean energy transition. Loop has said, fuel costs make up approximately half of the total cost of ownership for heavy-duty hydrogen vehicles, making fuel efficiency a key factor in creating a tipping point for commercial vehicles.

Revealed at IAA Transportation in Hanover, Germany on September 19 (2022), Loop Energy anticipates the S1200 to open up a new market for the company, offering quicken integration for vehicle OEMs, Loop says the S1200 is a ready-to-adopt solution.

Ben Nyland, President & CEO of Loop Energy, said, “We are proud to say that Loop Energy is leading the way in bringing the decarbonisation of the global transport industry even closer with the launch of our new fuel cell system. The S1200 brings world-leading fuel efficiency levels for medium to heavy-duty vehicles, crucially making the total cost of ownership lower and bringing cost parity forward by four-to-eight years.

“We are keen to work with OEMs, governments, and the wider hydrogen industry to help meet zero-emission targets. We strongly believe that energy transition must happen now, and hydrogen fuel cell technology is in prime place as an alternative to diesel-powered vehicles.”

How Loop Energy believes its S1200 beats diesel engines on fuel costs

Loop Energy said, “As an example, today, fuel consumption for an average loaded truck on long haul with a diesel engine is approximately 48 litres per 100 km, and with diesel priced between $1.83 to $2.28/L in Europe, the diesel fuel cost per 100 km for the truck is $87.95 to $109.46.

“Assuming a typical diesel engine efficiency at 44%, we can calculate the total energy the diesel engine produces to drive 100 km: diesel contains 10.03 kWh per litre, so the truck requires 211.74 kWh of energy over 100 km. Knowing we require 211.7 kWh of energy to drive the same distance using a hydrogen-electric truck, and that hydrogen contains 33.33 kWh per kg, we can determine the hydrogen fuel cost for comparison.

“Today, retail delivered hydrogen can be as low as $10 per kg, which corresponds to $90 in fuel cost over 100 km for the fully-loaded truck with regenerative braking, if fitted with a Loop Energy fuel cell with 60% efficiency. Here, the hydrogen fuel cost is already matching diesel fuel.

“However, if the truck was fitted with a typical fuel cell with 45% efficiency, the truck’s hydrogen fuel would cost $120 for 100 km, which is not in range of diesel fuel costs.  In this situation, hydrogen must decrease to $7.50/kg, or another 25% cheaper, in order to reach parity with diesel fuel cost.  Yet, another $2.5 reduction in cost of hydrogen is not expected until 2030, according to a report by Deloitte. So, Loop Energy has effectively brought hydrogen-diesel fuel cost parity forward by four to eight years, and its newest product’s fuel efficiency enables hydrogen to be competitive with diesel fuel cost now.”
