ULEMCo to introduce 50 kW hydrogen-fueled genset for urban environments

UK-based ULEMCo plans to launch a hydrogen-fueled 50 kW (KVA) generator later this year. The zero emission genset is targeted for use in urban areas, where the impact of harmful emissions from non-road mobile machinery (NRMM) is increasingly being understood.

When running over an eight-hour construction shift, the 50 kW genset will use around 15-20 kg of hydrogen, depending on the average load. It will emit zero emissions from an air quality perspective, without any aftertreatment, and depending on the source of hydrogen, will save up to 640 g/kWh CO2 against a diesel-powered counterpart.

When tested under the Type D2 ISO 8178 generator set engine standard, it demonstrates class leading thermal efficiency from the engine of up to 45%.

The work builds on the results delivered recently by ULEMCo’s R&D partners, Revolve Technologies, on 100% hydrogen engines. Working in collaboration with a genset integrator, the two companies will provide a solution that applies their experience of hydrogen energy systems with capability in clean combustion approaches, and knowledge of practical customer operational needs. The companies note that alternatives such as batteries struggle to be practical options for the full range of off-grid and backup power generation requirements.

Our initial work showed how an engine can be adapted to run on 100% hydrogen with zero emissions, and we were delighted to see the impressive overall efficiency results attained. Using hydrogen in this genset application instead of other zero emission alternatives like batteries, eliminates equipment down time for re-charging, and requires very little change of behaviour for the operators that would normally use diesel fuel. We believe that our prototype will gain significant interest from the industry.

—Paul Turner, Engineering Director at Revolve Technologies

ULEMCo plans to have a production ready genset available in the Autumn, and to have a prototype available for potential customers to trial in the next few months.

A few hours of freezing rain and many falling trees and broken branches created 325,000 power failures/outages in the local Hydro distribution lines in our region. Over 700 crews were required for 72 hours to fix all broken lines and outages

Too many (unreasonable) people plant trees under power distribution lines and then cry for help when those trees/branches fall and create power failures. All power cables in our immediate area are underground and we had no problem.

Small FC (10KW) clean power units could certainly be another solution for residences with tall trees near/under power lines. Hydro spent $73,000,000 last year to trim trees on private/city properties and more will be required.

That is the real answer, not distributed power. Hydro Quebec gets over 95% of electric power from water and has some of the lowest electric rates in North America.
Distributed Power would not solve the last mile of electric power distribution.
According to Quebec Power: "Québec has about 11% of the distribution lines below ground. Undergrounding any distribution system is more expensive than building overhead lines, and the decision is up to provincial and municipal authorities, not utilities."

Underground distribution power lines are relatively more expensive but a 5% increase in current energy very low cost, would cover the extra cost, over a 20 year period.

The majority would accept the extra (5%) cost, specially those with power failures due to broken trees. A 10 to 20 year programme could get it done. The current $100+M used to trim trees and repair damages would be greatly reduced.
