Liebherr partnership for green ammonia generators

Liebherr is partnering with Italian company Bruno Generators Group (BGG) on the feasibility of green ammonia for low and zero emission power generation in mining.

If successful, this will be another option for mining companies to reduce greenhouse gas emissions.

Liebherr has already investigated ammonia as a power source for dual-fuel internal combustion engines and the company’s Mining Equipment SAS executive vice president, R&D, engineering and production Oliver Weiss says he is excited to be working with BGG now.

“Their innovative mindset and tracked development and delivery of low emission solutions are a perfect match for us as we work towards our zero emissions targets,” he said.

‘When our combustion engines business unit saw promising results from ammonia as a low and zero emission power source after multiple test bench runs, we were excited to see how we could capitalise on this to provide even more ways our customers can pursue zero emissions.”

Bruno Generators Group chief executive Renato Bruno says the company is proud to partner and join forces with Liebherr Mining.

“Together, we share a common vision with an uncompromised commitment to sustainability, and we strive to lead the industry in responsible practices,” he said.

“This partnership represents an incredible milestone in our pursuit of sustainable solutions for the benefit of our customers in the mining segment.

“Sharing and blending our respective expertise will further enhance and naturally boost our innovation mindset, accelerating our journey toward a net zero future.”

Green ammonia, as a hydrogen carrier, can provide low or zero emission ways of supplementing power supplies on site through generators and off-board power units.

It has lower transport and storage costs compared with compressed or liquified green hydrogen.

Green ammonia generators are also a reduced emissions method of alleviating energy variations or blackouts on site.

Mobile offboard power units running on green ammonia can power electric excavators just outside the pit, reducing both emissions and infrastructure requirements.
