Hydrogen Ladder

The Hydrogen Ladder

Clean hydrogen is essential to limit global warming to below 2°C. Despite the influx of funding, widespread adoption is difficult due to the limited availability of green electricity. Michael Liebreich suggests prioritizing applications via his Hydrogen Ladder framework. In this blog post we explore its implications.

Hydrogen is used for more than you think

Clean hydrogen is on the rise. In many areas, it’s one of the few, if not the only, viable solutions to reduce CO2 emissions. The areas of use are many and varied. Providing a complete list is impossible, as new applications are emerging almost daily. To give you a sense of how diverse the market is, this post describes the five key areas of hydrogen applications, first at a glance and then in more detail. The post ends with a selection of applications from the different areas.

Hydrogen feeds the world

Fertilizer production requires large amounts of hydrogen. Today, 95 percent of this hydrogen is produced from fossil fuels, leading to colossal greenhouse gas emissions of CO₂. To save the Earth from more than 2 °C of global warming, politicians are using economic incentives to get the fertilizer industry to switch from fossil hydrogen to clean hydrogen produced by electrolyzers. This makes the fertilizer industry one of the largest markets for electrolyzers. In this blog post, we take a closer look at this little-known market, which, given its size, is more interesting than many of the more well-known ones.

E‑fuel made of hydrogen

E-fuel is an umbrella term for fossil-free alternatives to gasoline, diesel, and other fossil fuels. These fuels are produced by converting fossil-free hydrogen and capturing carbon dioxide. They can be used in existing engines without increasing the amount of carbon dioxide (CO₂) in the atmosphere. Is this the silver bullet that allows us to drive cars and other vehicles with a clear conscience?

Tech brief: Hydrogen classification systems

Hydrogen can be produced in many different ways and from different feedstocks. The choice of method and feedstock gives rise to more or less greenhouse gas emissions. In the general discourse on hydrogen and climate change, it is essential to distinguish between different types of hydrogen. As a result, systems have emerged to classify hydrogen, the most commonly known and used being colors. However, the European Commission has introduced one that focuses more on emissions. This tech brief explains the two systems.

Why capacitors?

Smoltek’s business division for the semiconductor industry, Smoltek Semi, focuses one hundred percent on capacitors. Why? After all, a capacitor is not a semiconductor. And what is the endgame for this venture? These are questions we address in this blog post.

On the Curse of Knowledge and the need for a glossary

Smolek has created a glossary of terms and abbreviations that may appear in the company's communication. Although everyone who writes for Smoltek does their best to explain in layman's words, technical terms inevitably creep into the text and make it difficult to read. This is due to a cognitive bias known as the Curse of Knowledge. This is the subject of this column, published on the spookiest day of them all – Halloween.

The machine

In March 2022, we told the world we had ordered a machine. In October 2023, we announced that it is ready for delivery. But what kind of machine is it? What does it do? Why has it taken so long? Where will it be located? How will it be used? You will find the answers here.

Carbon nanofibers in hydrogen electrolysis and fuel cells

Carbon nanofibers in hydrogen electrolysis & fuel cells Hydrogen has emerged as a key to store renewable energy and making heavy industry carbon-free. Two application areas of immediate vital importance. The core technologies that make this possible are hydrogen electrolysis and fuel cells. Electrolysis converts electricity into hydrogen, while fuel cells convert the hydrogen back to electricity.

Miniaturized capacitors with carbon nanofibers

Smoltek has developed the world’s thinnest discrete capacitor. You have to stack ten of them on top of each other to reach the same height as today’s industry-standard when it comes to surface-mounted capacitors. The most amazing thing about this microscopic capacitor is its performance. One square millimeter has a capacitance of a whopping 650 nanofarads (650 nF/mm2). Read on for more details.
