High-temperature heat
Many industrial processes require continuous heat at temperatures that limit straightforward electrification.
INDUSTRIES
Focused on the sectorswhere the challengeis greatest.
Terravia works with energy-intensive industries where high-temperature heat, process emissions and long-lived assets make decarbonisation particularly complex.
We bring sector context together with technical, economic and investment analysis to identify pathways that work in the real world.
Industrial decarbonisation across hard-to-abate sectors.
HARD-TO-ABATE INDUSTRY
Different sectors.A shared transition challenge.
Heavy industry cannot decarbonise through electricity procurement alone. Emissions are embedded in production processes, thermal systems, feedstocks and assets designed to operate for decades.
Each sector requires a different combination of technologies — and a different path through the transition.
Process emissions
In some sectors, emissions arise from chemical reactions inherent to production rather than from energy consumption alone.
Long-lived assets
Kilns, furnaces, reactors and other major production assets can remain operational for decades.
Infrastructure dependencies
Electrification, hydrogen and carbon capture can depend on energy and transport infrastructure beyond the facility boundary.
INDUSTRIES WE SERVE
Deep context wherethe decisions are hardest.
Our work focuses on four energy-intensive sectors where technology choices, capital cycles and infrastructure constraints create particularly demanding transition decisions.

01CEMENT & LIME
Decarbonising the process,not just the energy.
Cement and lime face a fundamental challenge: a significant share of emissions originates directly from the chemistry of production.
That means efficiency and fuel switching alone cannot deliver deep decarbonisation. Producers must consider a portfolio spanning clinker reduction, alternative fuels, electrification and carbon capture — while managing assets built to operate for decades.
TRANSITION LEVERS
- Efficiency
- Reduce thermal and electrical demand.
- Alternative Fuels
- Displace fossil thermal energy where technically viable.
- Clinker & Material Innovation
- Reduce the carbon intensity of the final product.
- Electrification
- Address suitable thermal and auxiliary processes.
- Carbon Capture
- Manage residual process emissions that cannot otherwise be eliminated.
02GLASS & CERAMICS
Rethinking heat withoutcompromising the process.
Glass and ceramic production depends on sustained high-temperature heat, often delivered by furnaces designed around fossil fuels.
Decarbonisation requires balancing new energy systems with furnace performance, product quality, infrastructure availability and tightly defined replacement windows.
TRANSITION LEVERS
- Efficiency
- Improve furnace and process performance.
- Electric Melting
- Electrify processes where product and capacity requirements allow.
- Hybrid Furnaces
- Combine electrical and combustion technologies.
- Hydrogen
- Evaluate applications where direct electrification remains constrained.
- Asset Timing
- Align major technology changes with furnace rebuild cycles.
03CHEMICALS
Untangling energy,feedstocks and carbon.
Chemical production combines diverse processes with complex relationships between energy, raw materials and emissions.
The transition can involve electrified heat, low-carbon hydrogen, alternative feedstocks, efficiency and carbon management — with economics varying significantly between products and locations.
TRANSITION LEVERS
- Process Efficiency
- Reduce energy and material intensity.
- Electrification
- Replace fossil energy in suitable thermal processes.
- Low-Carbon Hydrogen
- Decarbonise existing hydrogen demand and enable selected new processes.
- Feedstock Transition
- Evaluate lower-carbon and circular raw-material pathways.
- Carbon Management
- Address unavoidable or difficult-to-eliminate emissions.
04METALS
Transforming some of industry'smost demanding assets.
Metals production combines extreme temperatures, large energy requirements and long-lived capital assets.
Deep decarbonisation can require changes not only to energy supply but to the production route itself — making technology selection and investment timing critical.
TRANSITION LEVERS
- Energy Efficiency
- Optimise existing production assets.
- Electrification
- Expand electrical processing where technically appropriate.
- Hydrogen
- Evaluate hydrogen-based routes for selected processes.
- Recycled Feedstock
- Increase circular material pathways where product requirements allow.
- Process Transformation
- Transition toward fundamentally lower-carbon production routes.
ACROSS THE PORTFOLIO

Energy
Where will the energy come from?
Assess electricity, hydrogen, fuels and other energy requirements alongside infrastructure availability.
Economics
What makes the pathway viable?
Test capital requirements, operating economics and exposure to uncertain future energy and carbon prices.
Assets
When can the transition happen?
Align major interventions with rebuilds, shutdowns, replacements and existing capital programmes.
Infrastructure
What needs to exist first?
Identify grid, hydrogen, CO₂ and other external dependencies that constrain deployment.
Capital
What deserves investment?
Prioritise opportunities and sequence capital across sites, technologies and competing requirements.
