The HEIDI: Hydrogen Electric Integrated Drivetrain Initiative project will develop a hydrogen fuel cell double-deck bus, using innovative, low-cost fuel cell technology developed in the UK. This fuel cell bus will only emit water. Hydrogen fuel cell technology is crucial to decarbonizing our public transport and improving air quality in our towns and citi...

The push to decarbonise heavy-duty vehicles lags far behind light-duty applications. This is primarily because the extreme demands on powertrain cost-performance, operational availability, design life and reliability are yet to be wholly met by any existing low carbon powertrain approach, such as fuel cells, battery electric, hybrids and use of alternativ...

H2GEAR develops a disruptive modular aerospace electrical power generation and propulsion system powered using hydrogen, enabling emission free flight, with water as the only by-product. The innovative modular powertrain comprises a hydrogen fuel cell system and next generation cryogenic motor/drive and electrical network. A smart venting system, which ai...

With hydrogen-electric aviation as the only credible large-scale zero-carbon aviation option, the HyFlyer II project aims to take huge steps towards accelerating its adoption. It will repower an existing sub-regional airframe with a certifiable 600kW powertrain developed by ZeroAvia, integrating Aeristech's unique air compression technology. To complete t...

The project will develop a novel energy recovery and boosting system for internal combustion engines, leading to a step change in vehicle energy efficiency, fuel consumption and CO2 emissions. Aeristech’s Full Electric Turbocharger Technology (FETT) is a mechanically decoupled turbochaqrger and comprises of 3 elements; (1) an electric turbine generator re...

The aim of this project is to bring Aeristech’s novel electric supercharger to TRL 6/7 maturity level (“A-Sample” in the terminology of the automotive industry). This will build upon Aeristech’s successful proof of concept grant project completed in Q1 2014, and make the technology commercially attractive. Once at TRL 6/7, the automotive industry is welle...

This project aims to make turbomachine compressors available to the fuel cell industry. This requires aerodynamic, electrical, and mechanical innovations, but if successful it will provide the most low-cost, compact, efficient, and scalable compressor for automotive fuel cell systems. The project will use an aluminium, turbomachine-type compressor with vo...

This project will investigate the possibility of providing high levels of boost (2 bar target) to small engines (2.0 litre or less) when they are idling and running at low speeds (less than 2000 RPM) with a compact, efficient turbocompressor. Historically, the requirement for high pressure with low flow is met only by positive displacement compressors (ro...
