Technology directory
Energy technologies, explained independently.
We start with your business and its energy requirements — not with a product. This directory sets out the renewable, low-carbon, efficiency, storage, flexibility and electrification technologies available to UK organisations, and what actually determines whether each one fits.
19 categories · 107 technologies
Browse by category
Categories are maintained by UEG and expand as the market develops. Where we do not yet hold enough substantiated detail on a technology, we say so rather than filling the gap.
Renewable generation
Solar, wind, hydro, geothermal and bioenergy.
5 categories · 29 technologies
Solar
Photovoltaic and solar thermal technologies for commercial and industrial sites, from rooftop arrays to ground-mounted schemes.
Wind
Onshore, small-scale and offshore wind generation technologies.
Hydro
Water-driven generation and pumped storage technologies.
Geothermal
Energy recovered from the ground, mine water and deeper geological resources.
Biomass and bioenergy
Fuels and conversion technologies derived from biological and organic feedstocks.
Storage & flexibility
Electrical and thermal storage, flexible demand and grid services.
2 categories · 17 technologies
Heat & efficiency
Heat pumps, heat recovery and demand reduction.
3 categories · 17 technologies
Heat pumps
Electrically driven heat pump technologies for space heating, hot water and process heat.
Heat recovery
Technologies that capture and reuse heat that would otherwise be rejected.
Building energy efficiency
Measures that reduce demand before generation is considered.
Networks & controls
Energy management, private networks and power quality.
2 categories · 15 technologies
Low-carbon fuels & power
Hydrogen, fuel cells, CHP and distributed generation.
3 categories · 13 technologies
Transport, waste & carbon
EV infrastructure, waste-to-energy and carbon management.
4 categories · 16 technologies
EV and transport electrification
Charging infrastructure and vehicle-grid technologies for fleets and workplaces.
Waste to energy
Recovering energy from residual waste and waste streams.
Carbon management
Technologies for capturing, using and storing carbon, and for decarbonising industry.
Emerging technologies
Technologies at earlier commercial maturity that do not yet justify their own category.
Suppliers behind the technologies
Alongside the technology directory we are building an independent UK supplier directory — manufacturers, distributors, installers, EPC contractors, integrators, consultants, funders and software providers.
Not sure which technologies are right for your sites?
An Energy Transition Review starts with your consumption, operations and constraints — then identifies which of these technologies are worth pursuing, and in what order.
