You see steam. We see…

Steam is familiar in nature and part of life every day.
Yet this extraordinary fluid is a high efficiency, mission-critical tool for diverse and important industries, and increasingly relevant as part of our sustainable future. Steam is too small a word for it. This is Natural Technology.

NATURAL TECHNOLOGY,
INCREASINGLY SUSTAINABLE

STEAM - THE TRANSITION TO GREENER TECHNOLOGIES

More and more industries and organisations are recognising steam as the Natural Technology that fits with their sustainability agendas. With new steam generation technologies, we're on a path towards carbon-free steam generation.

FUTURE READY, NOW

NATURAL TECHNOLOGY FOR TODAY'S WORLD

Industrial scale solutions are already in operation to generate steam in cleaner, more sustainable ways.

RENEWABLE, ELECTRIC STEAM

Carbon-free, emissions-free, and 100% renewable steam. Higher capacity users in commercial and industrial sectors are able to decarbonise their steam generation today, thanks to the power of electric systems. Such systems align well with the portfolio of solutions driving progressive companies towards a truly sustainable business.
When coupled with 100% renewable power sources, such as hydroelectric, PV solar and wind, electric steam generators are capable of 1 to 20 tonnes of steam production with no emission or carbon generation. They are capable of converting renewable electricity into steam at 97% energy conversion efficiency.

BIOMASS STEAM BOILERS

BIOMASS STEAM BOILERS

Steam can be generated from combustion of organic waste materials such as olive pulp, rice husks and palm kernel shells created from various manufacturing processes. Biomass can be used to generate electrical energy as well as heat, when used in a Combined Heat and Power (CHP) systems. The reduction of organic waste and the utilisation of biomass, helps to improve environmental sustainability and lower energy bills.

...AND TOMORROW'S

Rapidly advancing technology will deliver on the promise of zero carbon steam generation.

THERMAL BATTERY

Thermal batteries offer a sustainable steam generation alternative, harnessing renewable electricity which is stored as thermal energy, enabling release of steam on demand for an array of industrial applications. Each thermal battery has an expected thermal efficiency of above 90%, a lifespan of 20+ years with minimal maintenance and no loss of performance. An exciting pathway to zero emission steam.

STEAM FROM HYDROGEN

With a 2030 target of 10m tonnes per year, green hydrogen plays a big part in the transition to a lower carbon economy as steam can be generated without producing carbon dioxide alongside it. Watch this video to learn more.

STEAM GENERATING BOILERS

NET ZERO HYDROGEN POWER

STEAM GENERATING BOILERS

While burning natural gas generates approximately 10% carbon, burning hydrogen generates no carbon emissions. Hydrogen-only energy centres are developed specifically to support the UK Government’s target of net zero by 2050.
This technology is well suited to boilers for steam generation. The hydrogen infrastructure requires further development, but there is no cost premium for a zero carbon hydrogen-ready burner for steam generation at scale. The technology has also demonstrated a 10% reduction in flue gas volumes, meaning significantly improved boiler efficiency.

SHOWCASE: DIGITALISATION

Remote monitoring and control of steam systems will play a key role in steam's sustainability journey.
In place of inefficient reactive responses to problems, digitalisation brings early alerts, predictability and rapid problem-solving, with new levels of control for customers.

Greater efficiency

Problems are detected and acted on immediately, before more severe issues arise.

Extension of product life

Early problem detection means smarter maintenance and repairs.

Carbon savings

Optimised steam systems result in a saving as energy emissions are reduced.

Process gains

Sub-optimal system detection enables improved process productivity.
