The LC30 generator, which AFC hopes can displace diesel generators, offers a 50% mass reduction, 45% reduced volumes, while being 20% efficient than the company’s previous versions.

It is also slated to have an increased operating range, from -20°C to +50°C, and can accommodate 100KW fuel cell to increase output on demand.

AFC says the unit will achieve regulatory approval, progressing to certification and pre-production. It has not yet specified a timeline.

It comes as the culmination of a 10-month programme working with power solution manufacturing firm Volex, where AFC aimed to improve the economics of its generators.

John Wilson, CEO of AFC, said the development aimed to “drive toward cost parity” with diesel generators, surpassing 66% reduction targets.

The technology comes as a key arm of AFC’s business strategy, which looks to provide fuel cell generators and hydrogen fuel – cracked from ammonia – on-site to end-users.

Under its hydrogen-as-a-service offering, the company plans to deploy its small-scale ammonia crackers and generators across UK construction sites through its joint venture with construction equipment hire firm Speedy Hire.

It intends to sell hydrogen on-site for £10/kg – which it claims meets cost parity with diesel generators – with no upfront costs for customers.

Wilson stressed that AFC was “well-positioned” to convert opportunities into firm orders.
