Up until now, Italian company Landi Renzo has been mainly known for its conversion sets for gas engines. Now the automotive supplier, which employs more than 1,200 staff globally, is venturing into the hydrogen sector and developing an advanced electronic pressure regulator for medium- and heavy-duty vehicles with H₂ combustion engines.

The Cavriago-based company has joined forces with German group Bosch to help it broaden its range beyond components for natural gas, biomethane or LPG. Its aim is to produce and market hydrogen-based fuel systems with next-generation mechatronic pressure regulators before the end of 2024. In doing so, Landi Renzo hopes to become an enabler of carbon-neutral commercial vehicle operation and thus play a part in accelerating the decarbonization of the mobility and transport sector.

Damiano Micelli, head of technology, commented: “This mechatronic hydrogen pressure regulator is an important milestone in technological advancement which we are able to offer to the rapidly evolving mobility and transportation market. […] This is a highly innovative solution that will be available shortly for medium- and heavy-duty applications.”

Pressure regulators are a key element in conversion kits since they help to balance out large pressure differences and, if needed, change the state of a particular fuel. According to Landi Renzo, “a simple and robust mechanical regulator” was previously sufficient to fulfill this function. However, mechatronic pressure regulators such as the EM-H can also control and calibrate the hydrogen delivery pressure in line with vehicle requirements. In a two-stage process, the inlet pressure is initially reduced mechanically from high to medium. The pressure is then lowered entirely electronically to the desired value.

Landi Renzo has over 70 years of experience in the automotive and energy sectors and its facilities include an H₂ center of excellence in Bologna which has a well-equipped, modular Class 8 clean room.
