Renewable energy harnessing in future mobility - can close collaboration across sectors enable greener tranformation?

EV sector is growing fast. As many people already drive electric vehicles, and due to the current development of railways, we of course expect that the energy source is also green, do we?

Let's take for instance Dutch railways. From 2018 every electric train on the Dutch railways NS network gets 100% of its energy from wind energy.

How did they achieve that? NS (Dutch Railways) has partnered with energy company Eneco to use its wind turbines to generate the energy needed to power all of its electric trains.

NS annually consumes 1.2 billion kWh of wind electricity, reportedly equivalent to the amount all households consume each year. The 100 per cent wind energy-powered trains transport 600,000 passengers and three strokes of an Eneco wind turbine drives a railway train one kilometre.

NS is using the sustainable energy on behalf of rail carrier association Vivens, which includes ProRail, Arriva, Connexxion, Kombi Rail Europe, DB Schenker, ERS Railways, HSL Logistik, Rotterdam Rail Feeding and Rurtalbahn Benelux.

But let's look into the Nordics.

Denmark has been a pioneer in renewable energy, particularly wind power, and has made substantial progress in incorporating green energy into various sectors, including transportation. In 2021, electricity from renewables accounted for 71.9% of Danish domestic electricity supply, compared to 68.0% in 2020.

The Danish railway operator, DSB (Danske Statsbaner), has committed to using electricity generated entirely from renewable sources to power its trains. However, they aimed to achieve this by 2025, striving to transition away from fossil fuels and embrace renewable energy sources like wind power. Today electric traction is just 37% of Denmark's overall energy efficiency costs.

In Sweden, more than 70% of all train lines on the main routes are now electrified. In Norway, this applies to 85% of all rail transport – calculated in train-kilometres. With Sweden possessing a number of hydroelectric and wind-powered energy plants capable of producing 100% renewable electricity, which could in turn be used for powering rail. Swedish railway operator SJ only purchases electricity from renewable sources. All renewable electricity in Sweden comes from wind and hydropower.

Also, the Norwegian railway operator Vy, sources its power with guarantees of origin. This provides a guarantee that the electricity they use is produced as renewable power at Norwegian hydro-power plants.

The current growth the Trans-European Transport Network (TEN-T) corridors and a boom in renewable energy sector in the regions regions like the North and Baltic Seas, seems to be a driving force in the transition to greener future. 

The connection between railway and renewable energy sectors is a catalyst for envisioning a future that embraces both connectivity and energy efficiency. The cooperative efforts between these two dynamic industries not only promise sustainable solutions but also contribute significantly to environmental conservation and technological innovation.

Integration of renewable energy in railway infrastructure

One transformative aspect lies in integrating renewable energy sources into railway networks. This integration holds immense potential, envisioning trains powered by renewable energy, thereby curbing carbon footprints and amplifying environmental sustainability. This synergy leads to reduced reliance on traditional fossil fuels, contributing positively to climate change mitigation efforts.

Improving connectivity and efficiency

The collaboration between these sectors could not only to enhance connectivity but also to fortify energy efficiency. By incorporating renewable energy systems into railway networks, we witness a dual benefit - improved connectivity and reduced energy consumption. This aligns seamlessly with the escalating demand for sustainable solutions.

Strategies for a harmonized future

To harness the full potential of this collaboration, concerted efforts are imperative. Strategic partnerships, joint research ventures, and technological innovations act as the cornerstone for propelling this synergy forward. Additionally, advocating policy frameworks supporting cross-sectoral collaboration lays the foundation for a harmonized and sustainable future.

Technological advancements and innovations

Exploring and implementing cutting-edge technologies that facilitate the seamless integration of renewable energy sources into railway systems is pivotal. Innovations in energy-efficient trains, smart grid technology, and renewable energy storage systems play a pivotal role in driving this transformation.

Economic viability and job creation

Analyzing the economic implications and investment opportunities resulting from collaboration between railway and renewable energy industries is crucial. Sustainable practices not only reduce operational costs but also create avenues for job opportunities within these evolving sectors, fostering economic growth.

Environmental preservation and climate impact

Detailed assessments of reduced carbon emissions and the broader environmental impact of utilizing renewable energy in railway systems are paramount. Mitigating climate change by reducing greenhouse gas emissions aligns with global efforts to preserve the environment for future generations.

Policy advocacy and regulatory frameworks

Examining existing policies and advocating for new frameworks that incentivize collaborative ventures between these sectors is essential. Addressing regulatory challenges and government involvement are crucial steps towards fostering an environment conducive to such partnerships.

Global case studies and success stories

Highlighting successful projects from various regions that integrate renewable energy into rail networks provides practical insights. Case studies serve as a testament to the feasibility and benefits of such initiatives, inspiring emulation on a broader scale.

Challenges and future outlook

Acknowledging challenges in implementing collaborative projects and strategizing to overcome them is imperative. Foreseeing the future trajectory, potential innovations, and expansions beyond the current scope are essential for sustained progress.

Social impact and public engagement

Understanding the social implications and promoting public awareness is crucial for widespread acceptance and support. Strategies involving community engagement and fostering public participation play a key role in shaping the success of sustainable mobility initiatives.

Railway and renewable energy sectors signify a monumental leap towards sustainable mobility. Collaboration, innovation, and strategic integration pave the way for a future that embodies efficiency, connectivity, and environmental responsibility. This synergy not only revolutionizes transportation but sets a precedent for a more sustainable and interconnected world.
