Slide Heading for a green future Electrification is not all about batteries.
Liquid e-fuel is one way to store electricity,
battery another

If the world community is to truly succeed in achieving the goals of the Paris Agreement, we must be able to think holistically. A successful conversion from fossil to renewable energy carriers requires that all parts of the supply chain receive credible and economically feasible zero-emission solutions. Our contribution is an engine technology that can utilize the new liquid energy carriers and contribute to realize a market for the new zero-emission fuels.

Liquified storage of electricity

Bio-Fuels and e-Fuels are expected to play a significant role in decarbonizing the transport sector.

Despite the efforts on electrification, there will be boundaries related to energy density and “recharging” which makes it obvious that this is not a global solution. E-fuels – liquified storage of electricity – might be.

Increased integration of renewable power into the global energy mix will be fundamental to achieve reduced dependency on fossil fuels. Wind and solar energy are inherently intermittent and power transmission networks are ill-equipped to accommodate fluctuating energy. Future energy systems will benefit from applying load-following storage technologies at large scale. Emissions-to-Liquids (ETL) and Power-to-Liquids (PTL) technologies can absorb surplus power generated at peak times and in remote locations. Storing surplus electricity as liquid methanol allows cars, trucks, ships, and power generators to leverage existing distribution infrastructure and gain access to new energy markets.

Methanol has a long history as a road transport fuel, and it is starting to make in-roads into the maritime sector as a marine fuel. In the past, interest in methanol as a fuel was largely driven by its high-octane level that can enhance the performance of vehicles. As a fuel, it can be blended with gasoline or used neat, and it was commonly used in high-performance racing cars. Recent interest in methanol is largely driven by the global trend to bolster sustainability and accelerate decarbonization. Methanol’s clean-burning properties allow it to offer immediate emission reductions when combusted in Internal Combustion Engines (ICEs).

Methanol’s ability to be produced from renewable feedstocks such as Biomass, Captured CO2 and municipal solid waste (MSW) allows it to be a carbon-neutral fuel aligned with the global agenda to decarbonize the transport sector.

Multifuel is the key

The environmental challenge must be addressed and the growing effort on develop and produce zero CO2 fuels is a part of our common sustainable future. E-Fuels and BioFuels are a global and achievable path to decarbonize transportation on land, air, and sea.

Petrol and diesel are hydrocarbons – composed of hydrogen and carbon atoms. While conventional fuels are derived from oil, e-Fuels get their hydrogen from water and carbon from the air, with these elements then combined to mimic the structure of petrol, diesel and other oil-derived fuels. The energy used to create synthetic fuels can be renewable, and while burning them generates carbon dioxide (CO2), capturing carbon from the atmosphere during synthesis can offset this. eFuels can also be a smart way of storing energy generated by renewable sources during times of low demand. It`s actually liquefied storage of electricity.

There is a number of different e-fuels on the block, all with different fuel properties and areas of application.  The future will tell if there is one winner or a number of winners depending on the sector. The more diversified the picture is, the more important it is to have a true multifuel engine concept.

Patentec`s patented engine architecture, The Linear Rod Technology (LRT), with variable geometric compression ratio, offers the key features to adapt multiple fuels in a fuel-efficient way. An engine that can operate with different compression ratios, depending on the fuels at hand. This unique feature gives the flexibility to adapt to a wide range of  different e-Fuels that will be a part of our sustainable future.

Fuel efficiency

Traditional fuels, based on oil, are the most costefficient due to scale of operation, both on production and distribution. This is a position developed through decades,  but that does not have to be the case in the future. Through legislation and environmental fees, the authorities can change this picture. This makes it likely that fuel prices will increase in the future and the engines fuel effeciency will be even more important than today.

Infrastructure is reusable

The infrastructure for storage and transportation of liquid fuels are present in  the infrastructure  we have built to handle fossile fuels.  This infrastructure may easily be converted to handle a number of e-fuels.
