Key Takeaways

  • H2 serves as a fuel, industrial feedstock, and refinery/metals enabler.
  • Production method determines lifecycle emissions and climate impact.
  • Choice between electrolysis and steam reforming affects cost and scale.
  • Malaysia can use H2 for backup power, fleet decarbonization, and exports.
  • Decision-makers should weigh H2 vs batteries and direct electrification.

Why this matters today: the present landscape of hydrogen uses and energy transition

Today, hydrogen sits at a crossroads between tried-and-true industrial roles and fast-moving low-carbon pilots. Refineries and ammonia plants remain the largest customers, using high-purity gas for hydrodesulfurization, hydrocracking, and Haber‑Bosch synthesis.

Most supply still comes from steam methane reforming of natural gas, so carbon management and capture matter for real emissions cuts. At the same time, green hydrogen made by electrolysis is attracting policy support and investor capital.

Emerging activity includes fleet trials with fuel cells, industrial retrofits, and early power-to-gas projects that soak up excess solar and wind and return firm power when needed. Technology readiness spans mature chemical feedstock uses to newer mobility and storage pilots moving toward commercial scale.

  • Market dynamics:
  • Companies compare hydrogen to batteries and fuels to find highest value uses.
  • Malaysia can tailor projects to local grids, ports, and industrial clusters.

Understanding production choices, project design, and lifecycle carbon is crucial for shaping practical, low‑carbon outcomes.

Hydrogen in a nutshell: properties, production, and why it’s an energy carrier

Hydrogen packs a lot of energy into a tiny molecule, and that makes it useful across heat, power, and transport.

It is the simplest element and normally appears as a colourless, odourless diatomic gas.

Combustion with oxygen follows 2 H2 + O2 → 2 H2O and releases about 141.865 MJ/kg as useful heat. Flames can be faint and mostly blue or UV, so detection matters.

Nearly all current production comes from steam methane reforming, but electrolysis of water using renewables can make low‑carbon supply for critical uses.

As an energy carrier, it stores power that later converts to electricity in fuel cells or back to heat in turbines. Fuel cells combine hydrogen oxygen electrochemically to yield electricity, heat, and water with high efficiency and quiet operation.

What are the 3 main uses of hydrogen?

Hydrogen serves three practical, scalable roles that matter for Malaysia’s energy and industry.

First, it acts as an energy carrier for power and mobility. It supports backup generators, distributed generation, and fuel cell vehicles with fast refueling and zero tailpipe emissions.

Second, it is a core industrial feedstock. Plants use hydrogen to make ammonia, methanol, and other chemicals that underpin fertiliser and manufacturing supply chains.

Third, it helps refining and metals work. Refineries rely on hydrogen for hydrodesulfurization and hydrocracking, while metals producers test hydrogen as a reducing agent in low‑CO2 steel routes.

These three uses capture most near‑term demand and link reliability, productivity, and decarbonisation in clear ways.

Decision-makers should weigh safety, on‑site production, and cluster integration when choosing which use best fits their project timeline and costs in Malaysia.

  • Carrier role: bridges renewables and end uses by storing surplus power as gas.
  • Feedstock: mature, high‑volume needs favour local production or industrial clusters.
  • Refining & metals: aligns with rules for cleaner fuels and lower emissions.

Main use one: Energy carrier for power, backup generators, and mobility

Hydrogen functions as a versatile energy carrier that supports mobility, on-site generation, and long-duration storage. It links surplus solar or wind to later uses and helps operators manage supply variability.

Fuel cells in cars, buses, and trains

Hydrogen fuel cells convert fuel and oxygen into electricity and water. They let cars and heavy vehicles refuel quickly and travel far while producing no tailpipe emissions. Public transport agencies and rail operators test these systems where batteries add weight or need long downtime.

Stationary power and backup generators

Fuel cells and generators running on hydrogen deliver quiet, clean electricity for data centers, hospitals, and campuses. Compared with diesel, they cut local pollutants and can pair with solar to form resilient microgrids. Hydrogen also serves as a coolant in large generators thanks to low density and high thermal conductivity.

Grid storage via power-to-gas

Power-to-gas turns excess renewable electricity into hydrogen for later re-electrification. This storage option fills gaps batteries may not cover and unlocks new potential for peak shaving and demand management.

In the middle ground, a sleek, futuristic-looking vehicle powered by hydrogen fuel cells, conveying a sense of clean, efficient mobility. The background features a cityscape with modern skyscrapers and renewable energy infrastructure, hinting at the wider applications of hydrogen as an energy carrier for power and backup systems.

  • Practical note: safe ventilation, certified sensors, and careful heating design are essential.
  • Malaysia fit: transport corridors and industrial parks can host refueling hubs and behind-the-meter generation.

Main use two: Industrial feedstock for ammonia, methanol, and chemicals

Across industry, hydrogen helps convert raw materials into everyday chemicals and fertilisers.

Ammonia and fertiliser via Haber‑Bosch

Ammonia plants run at 150–250 bar and 400–500 °C over iron catalysts. Multi‑bed looping and gas recycling push overall conversion above 97% in large plants such as Al‑Jubail (1,300 t/d).

Hydrogen used in these units is traditionally produced using steam methane reforming from natural gas, though many producers evaluate green hydrogen to cut lifecycle emissions.

Methanol routes and carbon reuse

Methanol production follows syngas chemistry or CO2 + hydrogen routes. Catalysts like palladium‑copper on porous supports improve conversion and selectivity for cleaner products.

Hydrogenation and refinery roles

Hydrogenation converts unsaturated fats into stable oils at 140–250 °C and low pressure with nickel catalysts. Hydrodesulfurization removes sulfur to meet fuel standards and protect downstream catalysts.

  • On‑site generation, storage, and purification suit continuous plant needs.
  • Malaysia can blend retrofit green hydrogen with existing infrastructure for lower carbon intensity.

Main use three: Refining and metals — from hydrocracking to low-CO2 steel

Across refineries and mills, hydrogen plays a hands-on role in upgrading fuels and lowering emissions.

Oil refining: hydrodesulfurization and hydrocracking with high-purity hydrogen

Refineries depend on high-purity hydrogen for hydrodesulfurization (HDS) and hydrocracking to meet strict sulfur rules and to turn heavy fractions into lighter fuel products.

Many plants produce hydrogen on-site via SMR to secure steady gas supply and integrate compression and storage systems. UK refineries alone make over 100,000 t/y, showing industrial scale.

Steelmaking and metals: hydrogen as a reducing agent for a greener future

Metals processing uses hydrogen to reduce ores. It is already used commercially for tungsten and is being tested for copper oxides.

Hydrogen-based direct reduction of iron (DRI) is moving from pilots to demos. SSAB’s HYBRIT project in Sweden is a leading example aiming to cut carbon in steel production.

  • Key points: refining needs high-purity hydrogen for cleaner oil-derived products and higher yields from hydrocracking.
  • Metals opportunity: DRI technology could replace coke, lowering carbon from steel when low-carbon hydrogen is available.
  • Malaysia fit: project planning should link production, gas infrastructure, and co-location to unlock benefits.

How hydrogen is produced: natural gas reforming vs green hydrogen

Production choices shape cost and carbon outcomes. Supply today splits between large steam reforming facilities and electrolyzers that run on renewable electricity.

Steam methane reforming today: scale, cost, and CO2 implications

Steam methane reforming dominates industrial supply because it scales and costs less for steady, high-volume demand. Big ammonia and refinery plants commonly use on-site SMR fed by natural gas to keep continuous output.

SMR turns gas and steam into syngas, then shifts and purifies it to yield hydrogen. That route emits significant CO2 unless carbon capture is added. For scale, note Al‑Jubail’s single train at about 1,300 t/d using SMR-derived hydrogen.

Green hydrogen from electrolysis: renewable electricity in, hydrogen out

Electrolysis splits water using electricity. Proton exchange membrane and alkaline technology are the two leading options as manufacturing scales.

A plant produced using renewable electricity yields low‑CO2 hydrogen, useful for green ammonia, methanol, and fuel applications with strict emissions goals. Electricity costs and water access drive levelized cost of hydrogen, so Malaysian developers weigh solar, hydro, and grid tariffs closely.

Practical notes:

  • Early projects pair small electrolyzers with on-site use to cut logistics and prove operations.
  • SMR plus CO2 control or new electrolysis builds will both play roles as green hydrogen production grows.

Storage and transport realities: compression, liquefaction, and blending with natural gas

How hydrogen is stored and shipped shapes safety, cost, and the timeline for deployment. Practical choices influence whether a project suits local industry, transport hubs, or long‑distance export.

In the background, a distant landscape of rolling hills or a cityscape, hinting at the wider context in which this facility operates. The overall scene conveys a sense of technological sophistication, precision engineering, and the critical role of hydrogen storage in the energy transition.

Compressed or liquid hydrogen: energy density, leakage, and logistics

Compressed gas storage is common for near‑term use. Cylinders and composite tanks balance pressure ratings and inspections for safe operation.

Liquefaction boosts volumetric density but needs cooling below ~20.28 K and care with ortho‑to‑para conversion to limit boil‑off. Centrifugal compressors face back‑leakage issues because of low molecular mass.

“Hydrogen forms explosive mixtures with air between 4–74% and has a very low ignition energy.”

Pipelines and on‑site production: matching projects to market and time

Blending with natural gas can extend existing networks, yet operators must check energy per volume, appliance compatibility, and codes.

On‑site generation reduces trucking losses and matches output to demand. Purpose‑built pipelines or upgraded mains move large volumes to hubs and industrial clusters more efficiently.

  • Practical tips: model multi‑year demand, delivery range, and storage sizing before committing.
  • Malaysia fit: hub‑and‑spoke designs link on‑site generators, tanker deliveries, and future pipeline upgrades.
  • End‑use: heating and power equipment compatibility decides whether to use pure gas, blends, or local reformation.

Safety and handling: high flame speed, NOx, and best-practice mitigation

Managing risks starts with design choices that reflect hydrogen’s fast flame speed and low ignition energy.

Hydrogen is a high-energy element that forms explosive mixtures with air from 4–74% and autoignites near 500 °C. Flames can be nearly invisible, with blue/UV emissions, so visual checks are unreliable.

Combustion with oxygen produces water, yet high flame temperature may increase NOx. Burner design and after-treatment matter for emissions when using combustion systems.

Detection, ventilation, and materials: making systems safe

Early detection and ventilation are primary defenses. Install hydrogen-specific leak sensors, UV/IR flame detectors, and clear purge protocols for enclosures.

Materials and components must resist embrittlement and leakage. Use certified valves, seals, piping, and storage vessels per standards. Commissioning routines should include leak tests, detector calibration, and relief-device checks.

  • Technology choice affects profiles: fuel cells avoid flames and yield only electricity and water at point of use.
  • Training, product documentation, and compliance with Malaysian and international codes build trust and enable safe rollout.

Malaysia’s outlook: hydrogen projects, market potential, and use cases

Aiming to balance cost and decarbonization, Malaysian pilots plan clustered projects that share production and storage assets.

Local activity links renewables, industry, and transport. Small demonstrations pair solar farms with electrolyzers so a plant can run on low‑carbon fuel and capture operational learning.

Energy and industry: pilot projects in power, mobility, and refinery integration

Operators can pilot fuel cell buses and depot refueling for cars and light fleets along key corridors.

Refineries may test green blends to lower oil product intensity while keeping HDS and hydrocracking reliable.

Green hydrogen opportunity: solar-rich production and export potential

Solar-rich zones offer sites for green hydrogen production that feed local plants or ship abroad as demand grows.

  • Practical actions: trial hydrogen generators for hospitals and data centers to prove resilience.
  • Develop shared compression and storage to cut unit costs and speed learning.
  • Track steel DRI pilots and support feasibility studies for future scale-up.
  • Encourage partnerships among fuel cell suppliers, EPC firms, and financiers to improve bankability.

Result: focused pilots can unlock broader market potential while building skills, standards, and confidence for larger projects.
