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’.

Ever seen a Cracked Round Bar (CRB) test? In this video, we showcase in slow motion how a polyethylene test specimen fails under cyclic loading. The CRB test is specifically designed to simulate the slow crack growth (SCG) process in polyethylene (PE) and delivers faster results than traditional methods such as PENT and FNCT.

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.

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.

Dutch energy distributor Alliander asked Kiwa to research and visualize the combustion of hydrogen at low concentrations. Kiwa developed a special test box and recording. The video shows that at low concentrations, the probability of ignition of hydrogen is lower compared with natural gas.

As an authority in energy and water distribution, Kiwa has been involved in testing and certifying materials used in gas, water and other pipeline systems for years. Kiwa's material experts have accumulated a wealth of experience, utilized in residual lifetime and failure assessments, resulting in a well-equipped material research laboratory that serves the entire energy and water sector.

This month marks the start of the third phase of the public-private hydrogen research program HyDelta. HyDelta 3 focuses on the economic and technical integration of hydrogen gas into the national gas transportation and distribution system. As part of the HyDelta consortium, Kiwa is taking on a significant number of work packages within HyDelta 3.

Hydrogen (H2) plays an important role in the energy transition. Currently, hydrogen is mostly applied in industry, mobility and the built environment. In this infographic Kiwa's hydrogen experts zoom in on these three applications. Discover the role of hydrogen as an energy source, as an energy carrier, for vehicles and for decarbonising the natural gas grid.

Kiwa joins forces with Eriks and SHV Energy to showcase our hydrogen solutions at the Gastech Exhibition, 5-8 September 2023. We invite you to visit our stand A512 and discover the limitless possibilities of this clean energy source.

Both Japan and the Netherlands have a strong interest in hydrogen as a clean energy source and are working on its development and implementation. What are the strengths of both countries? Kiwa researched this for Rijksdienst voor Ondernemend Nederland (RVO). This resulted in the action plan 'Towards reducing hydrogen supply chain costs', which you can download below.

To prevent further global warming and combat climate change, worldwide effort is being put into low-carbon, affordable and reliable energy solutions. Hydrogen can meet the energy and raw material needs of industry, the built environment and the transport sector, sectors that are difficult to decarbonize. However, depending on the application, hydrogen must meet certain quality requirements.

In natural gas distribution, odorization contributes to a high level of safety and this will be no different for hydrogen distribution. In this whitepaper Kiwa’s expert odorization Erik Polman takes a closer look at the odorization of hydrogen. What exactly is an odorant? What types of odorants are there? And how do we know whether a certain odorant is sufficient? The paper outlines what experience has already been gained in determining an odorant for hydrogen and also discusses the challenges that remain.

Zero-emission transportation, greater flexibility of the electricity grid and cleaner industrial processes are all necessary to realise energy transition. Hydrogen, thanks to its characteristics, contributes significantly to the achievement of this ambitious goal. Discover the flammability limits in air, molecular mass, thermal conductivity, heating values and the other important properties of hydrogen in a clear infographic.

Autumn 2022 Kiwa has started two new projects in Portugal for two Portuguese gas district system operators: H2REN for REN Portgás and Retrofit for Floene. In commission of these two operators, Kiwa will assess the suitability of their gas distribution networks for hydrogen.
