Rail: UK and around the world


The Challenge for the Rail Sector Worldwide

1. To de-carbonise rail operations now and cost effectively as the rail industry requires a positive payback model on all investments

2. Find and deliver new fuels and a new infrastructure for sustainable, deliverable, cost-effective low carbon energy

The Facts

UK Rail is one example where:

25% of all UK passenger trains are diesel powered
90% of all UK freight trains are diesel powered
Diesel engines are efficient, and numerous and so will be difficult and prohibitively expensive to replace in the short and medium term. 
They are also already made, as are the vehicles they run on, so represent a vast quantity of already ‘sunk carbon’.


Cleaner fuels are available. These can be biofuels Bio LPG, Bio LNG as well as Hydrogen, Ammonia and Methanol.
Transmission towers
Electricity is not necessarily:  
  • Available
  • Green; or
  • Affordable
Some parts of the network demonstrate that electrification can never be economically justified (or is simply impracticable (i.e. freight)).  So, there will always be a need for self-powered trains.
Renewable fuels such as bio-LPG and bio LNG have a far higher energy content than batteries or hydrogen
Cleaner Fuels are available and can be delivered NOW within the existing fuelling infrastructure utilising existing assets. This allows for future new refuelling infrastructure to be established for zero emission fuels such as hydrogen, methanol and ammonia.

A Solution

One BIG Solution, which requires only SMALL change has already been demonstrated in the UK and USA by G-volution Ltd: a fuel agnostic approach to immediate use of cleaner, greener and cheaper fuels on the rail network.
The proven concept of dual fuelling is to enable diesel power trains to run on two fuels at the same time. This ensures use of cleaner Fuels in a gradually expanded fuelling infrastructure. The train can run on diesel only when required.
The results of this concept in the UK rail framework have been set out in the G-volution feasibility study for the RSSB.

The report illustrates that, on an example train route (‘diagram’) the operator may:

Reduce carbon by 26-44% (depending on which fuel is used, and the replacement ratio)

Reduce fuel costs by 33-42% (again, dependant on fuel chosen)

Reduce particulate matter by up to 60-90%

G-volution Dual Fuel Experience:

G-volution delivers maximum Engine Efficiency and Secondary Fuel Substitution based on 10+ years of Dual Fuel experience. G-volutions patented technology has been deployed in Rail, Road [HGV] and static power generation.
