90–130 °C
Data centres
Firm power for AI campuses, with the turbine's waste heat driving absorption chillers instead of electric cooling.
900–1,500 °C
Steel
Hydrogen and high-grade heat for direct-reduced iron, without a blast furnace and without gas.
300–850 °C
Hydrogen and chemicals
Solid-oxide electrolysis at 700 °C uses 30 % less power per kilo than electrolysis at room temperature.
80–120 °C
District heat
Half the energy in fuel ends up as low-grade heat. Near a city, that heat warms 90,000 homes.
60–160 °C
Water
Thermal desalination that runs on heat that would otherwise be thrown away, instead of gas.
250–500 °C
Shipping fuels
Green ammonia and methanol, made at the port where the ships refuel.
Electricity
Utilities and the grid
Firm, synchronous power that uses the connections old coal plants left behind.
900–1,450 °C
Cement and glass
Electric kilns and furnaces, backed by power that is there every hour.
Electricity is halfthe story.
Two thirds of industrial energy is used as heat. Halvard's blanket runs at 650 °C, hot enough to replace gas in most of what factories do, and it can switch between heat and power every hour.
You buy megawatt-hours.We keep the star lit.
We finance and build
Halvard owns the plant. You sign a 20-year offtake at a fixed price, indexed to inflation, with no capital on your balance sheet.
We run it
Our operators, our licence, our spare parts. A 60-person crew per plant, trained at our own simulator in Cardiff.
You take power and heat
Electricity at the fence, steam or hot salt by pipe. Switch the mix hour by hour as your process needs.
