Sometimes liquids occur unintentionally in the gas distribution network. These include, for example, condensed gases from the gas network, often referred to as ‘natural gas condensate’. Liquids in the gas network can be harmful to both human health and the environment. Therefore, correct procedures for removing these liquids are essential. The procedures depend on the type of liquid, which cannot always be determined by visual inspection. Fortunately, there is a solution: infrared spectroscopy (FTIR). This measurement method makes it possible to identify the type of liquid.

At the request of Dutch drinking water company Vitens, Kiwa conducted an energy and decarbonization scan for Spannenburg, the largest drinking water production site in the Netherlands. The scan provides insight into Spannenburg’s energy consumption and explores possible measures to make the site more sustainable. The results provide building blocks for further steps towards reducing CO2 emissions.

The energy transition is leading to a growing need for excavation work in the Netherlands. The installation, replacement and reinforcement of cables and pipelines increasingly requires work to be carried out underground. Careful excavation is essential, as damage to data cables can disrupt internet, television and telephone services, causing inconvenience for users and costs for companies and society.

This case study highlights the challenges, expertise and detailed process involved in testing liquid hydrogen (LH2, chemically H₂) systems, based on the experience of Kiwa as an independent testing laboratory. To understand what this work entails, this case study takes you through the landscape in which LH₂ technology is developing, the capabilities of Kiwa and the step-by-step testing process that customers can rely on.

Water boards treat vast amounts of wastewater daily, leaving behind sewage sludge. This sludge presents an opportunity to contribute to the energy transition by digesting it into biogas, which can then be upgraded to green gas. By doing so, water boards can make their energy supply more sustainable and play a circular role in the energy market.

Waste processors play a key role in the circular economy. By converting organic waste into green gas, you can contribute to the energy transition while making your operations more sustainable. Additionally, green gas provides an extra revenue stream and helps optimize the use of residual waste.

Green gas is playing an increasingly important role in the Dutch energy transition. The government is actively promoting a mix of renewable energy sources, including wind, solar and green gas. The goal is to produce two billion cubic meters (BCM) of green gas annually in the Netherlands from 2030 onwards. Let’s dive deeper into the trends, developments, and opportunities.

Converting manure into green gas can help address manure surpluses, reduce methane and nitrogen emissions and generate an additional source of income. But how does this work in practice?

Green gas is gaining popularity as a sustainable alternative to fossil natural gas. It helps reduce CO₂ emissions and contributes to the energy transition. But what is it exactly? And how does it differ from biogas? In this article, we will guide you through the basics of green gas, its injection into the natural gas grid and what is involved in the process.

Kiwa, together with Alliander, DEP and Stedin, has won the IGU Global Gas Award during the 29th World Gas Conference (WGC2025) in Beijing. The award was granted for the paper ‘OGMP 2.0 Methane Emissions Reporting: The Dutch Approach’.

How can your Smart Energy Hub prepare for a future where hydrogen plays a central role in the energy transition? Let’s explore some critical questions that can help your hub make strategic choices.

Kiwa is proud to collaborate with Hydriven, the student team from the University of Twente and Saxion University of Applied Sciences, focused on developing a hydrogen-powered race car for the Formula Student competition. In this video, the team shares insights about their race car and what they aim to achieve with it.

Many people think of hydrogen as something new—a futuristic technology that has only recently gained attention. This isn’t entirely true. Hydrogen has been used for decades in industrial processes. However, numerous misconceptions still surround hydrogen, especially as it gains prominence in the energy transition. Let’s debunk some of these myths.

Is your industrial organisation ready for the energy transition? Many Dutch industrial companies are facing increasing pressure to reduce energy consumption, driven not only by societal expectations but also by stricter regulations. With the ambition to achieve climate neutrality by 2050 and a CO₂ reduction of 55% by 2030, the government expects companies to actively contribute to decarbonization. The question is: how can your business prepare and what role can hydrogen play in this?   

The energy transition involves significant changes: phasing out fossil fuels and switching to sustainable, clean energy sources. Hydrogen plays a key role in this shift. Although hydrogen has long been used in industrial processes, it is now gaining attention as a clean energy source. But why is hydrogen so vital in this transition? Let’s dive in.

In the application of hydrogen excess hydrogen inevitably occurs. To prevent its release, it is essential to equip vehicles and hydrogen networks with a boil-off management system (BMS) capable of efficiently venting excess gas. Kiwa's hydrogen expert Hans de Laat wrote an article on this topic.
