I braved the Christmas shopping and party crowds to join a group of people looking to make energy supply as reliable and efficient as possible.
PowerEx Live at the Park Plaza Westminster Bridge London gathers professionals from the worlds of combined heat and power (CHP), data centres, and ‘genset’ (generator set) – machines that produce electricity on-site – along with industry and consultancy folk.
The odd-sounding mix makes sense. Efficiency is critical not only to grid supply but also to temporary and emergency power and the growing, and energy-hungry, data centre industry.
Why ‘gensets’? Power interruptions cost money and are potentially lethal to healthcare, data centres and financial services, so backup is vital. Generators also serve construction sites, agriculture and remote functions such as mining.
CHP, or ‘cogeneration’ enables large energy customers in industry, commerce and institutions to capture and use heat that’s a by-product of on-site electricity generation – that would otherwise go into the atmosphere – a ‘win-win’ that saves money and reduces emissions.
Staff at the Preheat Engineering stand at Thursday’s event described how heating gas and liquids before use saves money and cuts pollution in industry and transport. Simon Gristwood, Managing Director said: “Machinery runs better and more cleanly at the right temperature. Look at how cars run smoothly with warm engine, and the smoke ship tunnels emit when the engines start.”
Car fan Simon, who has led the Slough-based UK manufacturer since 2015, is also an authority on the history of alternatives to fossil fuel and their outcomes.
Mark Gibbons, Sales Manager – CHP and Heatpumps at another exhibitor, 2G, explained how the Runcorn-based company’s plants reduce costs long-term and offer protection from rising electricity prices. “Our technology saves up to 40% in primary energy,” he said, adding that CO2 emissions dropped by up to 60% compared to conventional power generation in large power plants.
A fast-growing newcomer to energy markets, biogas is seeing big demand from traditional natural gas users who seek security of supply, protection from price volatility, and to reduce CO2 emissions.
Ben Chalk, Client Engagement Director of Future Biogas, said big-name industrial customers were happy to pay more for biomethane, to decarbonise their operations and for ESG benefits such as accelerating net zero.
Majority-owned by 3i Infrastructure since 2023 and now also with RWE as an investor, Future is building a UK network of anaerobic digestion plants to convert crops to unsubsidised biomethane. Farmers like long-term offtake deals and reviving soil through crop rotation, returning nutrients to the land.
A hot topic in breakout sessions was data centres. These are popping up around the world to store and process burgeoning information produced by our reliance on screens and growing demand by governments, businesses and institutions such as the NHS.
Power consumption by these low-visibility leviathans is growing fast, even before factoring in projected growth in AI, so demands for energy efficiency in the sector will be huge – something delegates no doubt pondered at a floating event after-party on the Thames.
