AN ALTERNATIVE WAY TO REDUCE CARBON, REDUCE COSTS - AND CLEAN THE AIR ON EXISTING RAIL ASSETS TODAY:

G-volution Technology Summary:

 

 

The concept:  diesel engines are extremely efficient and prevalent.  They do not need to run on diesel fuel.  They need to be cleaner, greener and cheaper to operate. G-volution has pioneered the concept of dual fuelling (CO-COMBUSTION) which enables diesel engines to run on two or more fuels at the same time replacing a large proportion of diesel with a cleaner and cheaper alternative fuel (see www.g-volution.com).  This enables existing (or new) diesel engines to run on cheaper and cleaner fuels, whilst retaining the flexibility to run on diesel if required.  This concept allows the possibility of introducing clean fuels cost effectively (3-5 year payback, including infrastructure) and delivering infrastructure in a range of fuels (depending on price and availability) including bio LPG (liquefied petroleum gas), bio-Methane (LNG, Liquefied Natural Gas), hydrogen, and potentially methanol (used in marine) and hydrous ethanol.

 

G-volution has pioneered this approach in the US Rail market, and the UK HGV market since 2008.  Both LPG and Natural Gas (LNG) – which have bio-gas equivalents – work in this context.  The technology is thus proven and therefore represents low technology risk.  The opportunity to decarbonise the UK rail sector is set out below.

 

The Issue:  In the UK Rail sector there is a need to:

There are some parts of the network where electrification can never be economically justified, or is simply impracticable (i.e. freight).  Freight operations (in the main) require vehicles that can ‘go anywhere’ which due to the aforementioned issues with economically electrifying the entire network means that freight traction will need to be self-powered for the foreseeable future.

  1. The Proposal, illustrated and demonstrated:  as stated above, the proven concept of dual fuelling is to enable diesel power trains to run on two fuels at the same time [see co-combustion as above].  This ensures use of cleaner eFuels in a gradually expanded fuelling infrastructure [in each fuel, natural gas, bio gas, bio LPG as required/available].  The train can run on diesel only when required. Thus there are no range or power issues unlike, say, batteries.

  

  1. Barriers to entry:  as with all rail projects there are significant barriers to entry.  These are all  overcome by the two projects, Grand Central Class 180 and Network Rail Class 73, during 2020,and include:

  1. NOTE:  THE ROLE OF NATURAL GAS, AND OTHER FUELS LIKE BIO-LPG, ARE PART OF RAIL DECARBONISATION STRATEGIES IN SCOTLAND, SPAIN, CALIFORNIA AND ITALY.  BIO-METHANE IS A KEY ELEMENT IN HGV DE-CARBONISATION IN EUROPE AND USA.  DUAL FUELLING HAS BECOME THE PROCESS OF EVOLUTION IN THE MARINE INDUSTRY ALSO.

 

  1. Conclusion:  in conclusion, given the practical and time constraints on the rail industry, G-volution proposes dual fuelling as a quick, sustainable,  low cost and low carbon alternative which immediately ameliorates the reality that a large part of the rail fleet will be powered by diesel engines for many years to come.  These can be established by demonstrating [on an engine test cell] the routes and duty cycles in question, the cost and environmental savings, and then implementing them.  The solution is both applicable to existing assets and new build. It is fully compatible with other solutions [such as hybrid and bi-mode] , will encourage the development of new infrastructures, especially hydrogen, and importantly, G-volution’s proposal allows for the use of zero net emission fuels in the future as and when infrastructure, fuel cost and availability allow.  

 

 

 

 

 

 

We cannot allow ‘the perfect to be the enemy of the good’– G-volution’s proposal can make an immediate, substantial, sustainable  and highly cost effective impact on decarbonisation to the benefit of train operators (lower carbon, lower fuel costs), and to train staff, to passengers and to the wider public (cleaner air)
