The Powerful Development of Hydrogen at CIHC 2026

Posted on 26 February 202626 February 2026 by Cassandra Brightley

China’s hydrogen industry is growing fast and is worth keeping a close eye on. The progress being made in hydrogen across the country is nothing short of incredible. The decisions made at CIHC are likely to have a positive impact on how hydrogen systems will be designed, protected and regulated for years to come.

CIHC is the China International Hydrogen Congress and Expo, an event held at the China National Convention Center in Beijing. This March, CIHC is the place to be if you want to understand where the hydrogen industry is heading.

This event is bringing together the people designing, building, and safeguarding hydrogen systems at scale. We’ll be there, alongside our Chinese distributor partner at this event, Shanghai Suitech M&E Co., Ltd (上海苏业机电设备有限公司), one of our several valued partners in China.

China Leading the Hydrogen Charge

China produced and consumed over 36 million tonnes of hydrogen in 2024, more than any other country in the world. Renewables now make up more than 60% of China’s total installed power capacity, and in 2025, China generated around 4 trillion kilowatt-hours of renewable electricity, more than the entire EU uses in a year. The BBC has covered this shift in depth, and their conclusion is hard to argue with: China is becoming a green superpower.

CIHC sits right at the centre of this. Now in its fifth year, CIHC 2026 brings together over 600 companies from more than 20 countries across a 50,000 m² exhibition floor. You’ll find 1,000+ products and technologies covering the full hydrogen supply chain, from production to storage, transportation and refuelling, all the way to end use. Alongside the exhibition, CIHC 2026 runs a plenary conference and more than 10 specialist sessions, bringing over 200 speakers and around 3,000 delegates.

The event runs from 25th to 27th March 2026 at the China National Convention Center (Phase I & II), in Beijing. It’s organised by the China Hydrogen Alliance, China Electricity Council, and Beijing Tiger Exhibition Co., Ltd., among others.

This year’s theme is “Towards Innovation and Greenness, Building a Win-Win Future.”

Endorsed Safety Valves and Gauges at Marintec China 2025

Posted on 15 December 20257 January 2026 by Cassandra Brightley

Managing a cargo ship, workboat, or an offshore oil and gas site brings its own set of challenges. You must keep people safe, protect your equipment, and the environment. Not to mention, you must bear in mind all the regulatory changes that take place.

You need clear, reliable readings of the liquids inside your tanks. As well as robust pressure safety management via safety valves. However, if your liquid level gauges or safety valves fail, you face expensive stops to your workflow and cause serious safety risks across your site.

Imagine the worry of not knowing the exact liquid level in a tank; it could cause issues for your team. Not enough fuel in the tank could leave them stranded. Not enough water in the tank for your crew’s journey… well.

What about a valve not opening when pressure builds up in a system on your ship or rig? That uncertainty leaves you feeling exposed and vulnerable to failure, and puts lives at risk. That’s why we attended Marintec China. These are the sort of challenges we specialise in solving, and we aim to help you find the right liquid level gauge or safety valve for your needs.

At Marintec China 2025, we spoke with project engineers, directors and fellow business associates about our products that lessen those worries. We give you a clear, easy ways to manage safety and measurement across your ships and offshore platforms, letting you focus on your project goals.

Connecting with the Maritime Industry at Marintec China 2025

The shipping and offshore industry is constantly changing. This is especially true as we direct more of our focus towards greener fuel solutions for the planet, such as hydrogen. Which is why you need equipment that can handle these new demands on both your ships and your platforms. That way, you ensure you’re doing the best for your people, business and environment.

So, what did we get up to at Marintec China 2025?

Our representative, Larita Prescott, met with engineers and decision-makers in the maritime industry from around the world. We listened to the challenges you face in today’s marine environment. Such as meeting new energy, safety, and efficiency standards. We shared how our UK-manufactured, certified liquid level gauges and safety valves can help. It was a pleasure talking with everyone who stopped by and with fellow businesses in the marine industry.

Talk to Us About Liquid Level Gauges

Knowing the liquid level inside your oil tank or water tank must be something you can do easily. You need a reliable liquid level gauge to ensure your systems are safe and your tanks have the right liquid levels. We have perfected this with two leading products for the shipping and offshore industry, which we had the pleasure of discussing at Marintec China 2025.

The G31 Seeflex Liquid Level Gauge

The G31 Seeflex liquid level gauge gives your team a direct, easy view of the liquid level in your tank. It has a robust, mild stainless-steel build, toughened borosilicate reflex glass and comes with push-button spring-loaded valves. The spring-loaded valves isolates the contents of your tank till your crew goes to check the levels. This gauge helps you get clear readings of your levels, minimise leaks, and is SOLAS compliant. Your certified and proven solution in demanding environments.

The G35 Seemag Magnetic Liquid Level Gauge

Our high-quality yet economical magnetic liquid level indicator for all-round visibility liquid level checks. The G35 uses magnetic technology to give a clear reading without touching the liquid itself. It keeps your team and site secure. It also has the option of high/low-level alarms with remote digital reading. Yet another robust liquid level gauge that is SOLAS compliant and proven in a range of harsh environments.

Your team, business and environment are our priority. Which is why we engineer high-quality and easy-to-maintain liquid level gauges that go through strict tests and gain a range of approvals. Making them applicable for use in different industries and regions across the world.

Safety Valves for Current and Future Challenges

As ships and offshore rigs adopt new fuels and face new regulations. Safety valves must be able to deal with these new challenges. As well as go through rigorous tests to pass the new regulations to ensure their suitability and performance for these challenges.

Project engineers, decision makers, managers and those further afield. Had the opportunity to learn and share their knowledge on these greener fuels, and the challenges they bring at Marintec China 2025. We also had the opportunity to share how our hydrogen safety valves are built to tackle the challenges greener fuels like hydrogen bring. Your team relies on their environment, your site, to have reliable protection against pressure build-up, both with standard and with emerging fuel systems.

You, I… we’re all aware of the progress the hydrogen industry is making. We’re seeing hydrogen-powered cars like the Mercedes-Benz GLC F-Cell, which uses combined hydrogen consumption, hydrogen-powered trains in California, and liquid hydrogen-powered ferries like the MF Hydra.

We also have Fincantieri and Viking’s announcement from April 2025, of the first cruise ship in the world that will be powered by hydrogen stored onboard the ship. That hydrogen will be used for both propulsion and onboard electricity. Hydrogen is becoming such a big part of so many different industries as a green solution to be used for the well-being of our environment. That’s why we have developed safety valves that aren’t just capable of dealing with industries like oil and gas, refrigeration, chemical, etc, but safety valves that are built for the future.

Seetru Hydrogen Safety Valves

We offer a selection of safety valves built to handle the demands of hydrogen and other new fuels, helping you meet future safety standards. Below we’ll go over some of our selection.

Seetru’s Change-over Valves

These valves allow you to switch between two relief valves without needing to turn your whole system off. This means you can keep work going and your team safe, while maintenance or valve replacement is being done. Having this level of flexibility is key for any industry, as well as for offshore platforms and the marine industry in general. We are proud to have had the opportunity to share more about our change-over valve selection at Marintec China.

Seetru’s Flanged Valves

For larger industrial systems or sites that require high flow capacity, our safety valves with flanged connections offer easy installation and removal without complicated piping adjustments. The flanged connection means securing the valve is straightforward and ensures a strong, long-lasting seal. Saving your team time during installation and maintenance.

Seetru’s Safety Relief Valves

Beyond our change-over valves and flanged valves. We also offer a range of compact safety valves well suited to the hydrogen industry supply chain. Including Type 646/641, Type 946H5/956H5 and Type 946 threaded. These are just a few mentions from a selection of safety valves that are designed to deal with the demanding pressures and conditions found across the hydrogen supply chain, from hydrogen production and storage through to dispensing and transport.

Built for hydrogen conditions
Materials like the stainless steel 316 and our valve designs are chosen to help resist hydrogen embrittlement and minimise the potential of cracks in the valve that would cause leakage.

Compact and space‑saving
Valves such as the 946H5/956H5 are compact, so they fit easily into small skid units, dispensers and compressor systems without the need for major layout changes.

Consistent workflow
Our advanced sealing technology and simple internal mechanisms are designed for optimal and repeatable opening and tight reseating of the valve. This is to minimise the possibility of leaks, which would bring your work to a halt.

Flexible connection options
Threaded versions like the Type 946 let you screw the valve directly into existing threaded connections on pipework or small pre‑assembled units. This makes installation quicker and simpler, especially in tight spaces or where adding flanged connections is not practical.
