What is blue gas, and who makes it?

Blue hydrogen, often referred to as blue gas, has become a focal point of interest in the last two years. This form of energy is derived from natural gas through a process known as steam methane reforming (SMR). During this process, carbon emissions are diligently captured, stored, or used, classifying blue gas as a low-carbon energy source.

The potential of blue gas, particularly as a crucial catalyst for the transition towards a green hydrogen economy, is widely recognised. Currently, the production of blue gas is more cost-effective than green hydrogen, which requires renewable energy and electrolysis. This positions blue gas as a practical alternative for nations and industries aiming to diminish carbon emissions in the immediate and medium term.

Various countries have acknowledged the role of blue gas in their energy transition plans. For instance, the UK government has pledged to follow a “twin track” approach, endorsing both blue and green hydrogen. Canada, with its vast natural gas reserves and carbon capture and storage (CCS) technology, is another country investing in blue gas.

In the corporate sector, major energy corporations such as BP, Shell, and Equinor are directing investments towards blue gas projects. BP, for instance, plans to establish a blue gas production facility in the UK, which could commence operations by 2027.

However, the mainstream adoption of blue gas faces certain obstacles. Its production is an energy-intensive process, and the efficiency of carbon capture and storage is not always absolute. There are also apprehensions regarding methane leakage during the extraction of natural gas, which could negate the carbon benefits of blue gas.

Furthermore, the declining costs of renewable energy and electrolyzers are making green hydrogen a more competitive option. Critics suggest that investments in blue gas could potentially divert resources away from green hydrogen, which is ultimately the more sustainable solution.

Blue Gas: The Contender Against Tesla?

The triumph of Tesla has silenced many sceptics and inspired marketers to envision investments that could yield Tesla-like returns. Tesla’s success has been so influential that it has propelled every automobile manufacturer to join the electric vehicle (EV) movement. In this scenario, a novel fuel known as blue gas is being promoted as the nemesis of batteries. The technology behind blue gas, essentially blue hydrogen, is being touted for its zero harmful emissions.

While blue gas has been projected as a cleaner substitute for conventional fossil fuels, its environmental benefits are a topic of ongoing discussion. The production of blue hydrogen is heavily dependent on natural gas, which serves as its primary raw material. To classify it as “blue,” the carbon emissions produced during steam methane reforming need to be captured and stored subterraneously. However, research indicates that carbon capture rates often fall short of 100%, leading to the emission of greenhouse gases.

Moreover, extracting and transporting natural gas leads to methane leakage, a formidable greenhouse gas. Some specialists estimate that blue hydrogen produces 20% more carbon emissions than directly using natural gas. Therefore, while advocates of blue gas argue that it burns cleaner than coal or oil, its overall climate impacts may not be significantly superior to existing fossil fuels.

Further research is necessary to enhance the efficiency and reduce the emissions of blue hydrogen production. Other sources of hydrogen, such as green hydrogen produced through electrolysis powered by renewables, might hold more potential as a sustainable fuel. To date, however, Blue Gas has not definitively earned the “battery killer” label that some marketers have assigned to it. There are considerable technical and economic challenges before it can realistically compete with electric vehicles and their rapidly evolving battery technologies.

The Art of Crafting Blue Gas: A Deep Dive into the Production Process! The production of blue hydrogen, or blue gas, primarily hinges on a process known as steam methane reforming (SMR), which employs natural gas as the main ingredient. The natural gas undergoes a reaction with steam at extremely high temperatures, resulting in a split into hydrogen and carbon monoxide. The subsequent phase involves the water-gas shift reaction, which transforms carbon monoxide into carbon dioxide and additional hydrogen.

To classify it as “blue,” the carbon dioxide emissions generated from these processes must be captured. This is typically achieved through carbon capture and storage (CCS) technology. The CO2 is compressed into a liquid state and injected deep underground for permanent containment. This process of emission sequestration lends blue gas its “low carbon” distinction in comparison to grey hydrogen, which is produced via SMR without CCS.

Elon Musk’s Perspective on Blue Gas: A Worthwhile Alternative or Not?

Elon Musk, the forward-thinking entrepreneur and CEO of Tesla, is known for his candid views on alternative energy sources. His stance on blue gas is no exception, as he has openly expressed his scepticism, dubbing the concept “mind-boggling” and “stupid.” In his typical candid style, he has even suggested that instead of being termed “fuel cells,” they should be referred to as “fool cells.”

Musk’s perspective on blue gas mirrors his profound commitment to electric vehicles and the widespread adoption of battery-powered cars. He envisions that electric vehicles, backed by their rapidly advancing battery technology, are the future of sustainable transportation. His scepticism towards blue gas likely arises from his concern that it may divert focus and resources from the development and enhancement of electric vehicles.

However, it’s crucial to acknowledge that there are varying opinions on the potential of blue gas as an alternative fuel source. Arval, a French bank BNP Paribas Group subsidiary, offers a contrasting viewpoint. They underscore several advantages of blue gas:

One notable advantage is the quick refuelling time, which is comparable to refuelling a gasoline vehicle, which takes only 3 to 5 minutes. This addresses one of the key drawbacks of electric vehicles, which typically require longer charging times.

Another benefit is the absence of harmful emissions. Blue-gas vehicles produce only water as a byproduct, making them environmentally friendly and reducing air pollution.

Furthermore, blue gas provides an impressive range of around 300 miles on a single tank, placing it on par with conventional gasoline vehicles. This extended range alleviates one of the common concerns associated with electric cars: range anxiety.

In terms of efficiency, fuel cell powertrains are highly efficient at extracting energy from hydrogen, surpassing the efficiency levels of traditional gasoline or diesel vehicles.

Given these differing viewpoints, the question arises: Is blue gas a viable and worthwhile alternative to conventional fuels and electric vehicles? While Musk’s criticism is well-known, it is essential to weigh the pros and cons objectively and consider the potential role of blue gas in the broader landscape of sustainable transportation. Ultimately, the future of blue gas will depend on ongoing technological advancements, environmental considerations, and the preferences of consumers and policymakers.

Navigating Challenges and Considerations in the Blue Gas Movement As we delve deeper into the world of blue gas as a potential substitute for conventional fuels, it becomes critical to scrutinise its merits and the challenges and considerations surrounding this innovative concept.

One of the main challenges in embracing blue gas technology is the limited availability of refuelling spots. Unlike gasoline or diesel, which have an extensive network of refuelling stations, the infrastructure for hydrogen refuelling is still in its early stages of development. This constraint can present a significant hurdle for those considering hydrogen-powered vehicles, as access to refuelling stations may be restricted in many regions.

Another aspect to consider is the cost of developing and implementing blue gas technology. While the expense of fueling a hydrogen vehicle may be on par with traditional fuels, the costs associated with building the infrastructure for hydrogen production, storage, and transportation are substantial. Storing and transporting hydrogen safely can be challenging and expensive due to its low density and unique properties, which require specialised equipment and facilities. These economic considerations can affect the affordability and accessibility of blue gas technology.

Moreover, the environmental benefits of blue gas heavily depend on the source of the electricity used to produce hydrogen. To genuinely realise a reduction in carbon emissions, the electricity powering the hydrogen production process must come from renewable sources. Without a shift towards renewable energy generation, hydrogen production may still involve carbon emissions, negating the environmental benefits often associated with fuel cell vehicles.

While blue gas presents a promising path for sustainable transportation, it’s essential to acknowledge the hurdles and prerequisites it involves. Overcoming challenges like the expansion of refuelling infrastructure, managing costs, and ensuring the use of renewable energy sources will be critical in determining the viability and success of blue gas as a revolutionary alternative to traditional fuels. As we traverse this evolving landscape, we must balance these factors against the potential benefits in our pursuit of a more sustainable future.
