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 Accelerated Notched Pipe Test (ANPT) plays a crucial role in assessing the resistance of polyethylene (PE) pipes to slow crack growth, because it mimics real-world installation damage. However, recent restrictions on the detergent Arkopal N100, traditionally used in the test, have posed challenges for compliance with international standards. This article explores the search for a more sustainable alternative detergent, with Kiwa Technology at the forefront of these developments.

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.

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.

Recently Kiwa has been announced as a finalist for the Hydrogen Awards of 2023, where businesses are highlighted for their contribution to the hydrogen industry. The commissioning of our new hydrogen production plant has played a major role in the nomination.

Hydrogen produced from renewable energy sources can make an important contribution to reducing greenhouse gas emissions. When hydrogen gas is to be transported through the existing gas pipelines, the safety level has to be at least the same as for the transportation of natural gas. This means that important safety questions need to be answered, for example when it comes to the leak tightness of pipes and components that are used with hydrogen gas.
