Which Industries Will Benefit The Most From Energy Sustainability Technologies?

Renewable Electricity

Tandem Silicon-perovskite Solar Cells

Tandem silicon-perovskite solar cells, based on ytterbium halide, enable the production of solar cells without the use of toxic lead, and offer flexible, lightweight, and semi-transparent cell designs. Compared to state-of-the-art crystalline silicon solar cells, which only achieve solar conversion efficiencies below 20%, these new types of solar cells can achieve solar conversion efficiencies of up to 25%. Manufacturing solutions, such as producing perovskite layers with roll-to-roll printing, mean that these types of solar cells can be produced with cheap, high throughput, continuous production processes. This approach offers distinct advantages over the conventional production processes used to manufacture silicon solar cells. Tandem cells are becoming commercially available, and are finding use in as part of “smart glass”, portable electronic devices, and in the automotive industry.

Concentrated Multi-junction III-V Solar Cells

Concentrated multi-junction III-V solar cells have set a world record for solar conversion efficiency. They achieve a conversion efficiency of 47.1% under 143 times the sun intensity through concentrated illumination, powered by a gallium indium phosphide/gallium arsenide six-junction cell. Using light concentrators, solar cells can be much smaller than the traditional solar cells while generating the same amount of electricity, reducing the panel’s relative cost by a factor of 100-1000 compared to flat-plane silicon cells. Multi-junction III-V solar cells with concentrators are bulkier than the thin-film counterparts, but have an unmatched performance for the applications in the energy sector.

Green Fuels


Biomethane produced from anaerobic digestion of biomass and enriched by removing CO2, hydrogen sulphide, and water can be used for green heating/gas networks. Biomethane distribution is compatible with the existing gas distribution infrastructure, and countries across the world are launching green gas grid schemes to promote the use of low carbon sources for heating homes and commercial buildings. With Italy being the current pioneer in large-scale biomethane production, the technology could be viewed as tried and tested and as ready for expansion, with a potential market of 10 billion m3 per year.

Algae Biofuel

Algae biofuel made from algae can be distilled into several petroleum-like products that could serve as replacements for gasoline, diesel, and jet fuels. Unlike fossil fuels, algae are a completely renewable resource and CO2 neutral. Compared to other biofuels, algae can produce 10-300 times more oil per acre, are environmentally friendly, and offer other useful by-products. Algae biofuel can be refined using processes similar to those used to refine petrol, and in addition to serving as a direct replacement for common fuels in the automotive industry, and it can also be used to produce fertilisers, cosmetics, and chemical feedstocks.

Energy Storage & Distribution

Solid-state batteries with AG-C Composite Anodes

Solid-state batteries with Ag-C composite anodes offer a three-fold increase in energy density, improved safety, and 50% decrease in cell volume compared to widely used lithium-ion batteries, which utilise liquid electrolytes. Existing prototype solid-state cells will drive the further market expansion of electric vehicles in a wide range of industries, thus disrupting the current mobility and logistics sectors.

Vanadium Redox Flow Batteries

Vanadium redox flow batteries allow grid-scale, long-term energy storage. Redox flow batteries offer power output and energy capacity that can be engineered independently of each other, enabling higher lifetime than in Li-ion batteries of up to 5000 cycles and up to 15 years of operation time. Redox-flow batteries offer a promising solution for large-scale grid energy storage, with facilities as large as 800 MWh in capacity currently under construction China.

Energy Efficiency

Thermochromic and Electrochromic Metal Oxides

Thermochromic and electrochromic metal oxides in smart windows allow for active control of the transmittance of infrared radiation while remaining transparent. These windows are estimated to reduce the energy consumption required for heating of up to 40% compared with traditional static windows, thus reducing energy-related CO2 emissions. Energy-efficient materials, including smart windows, are starting to be utilised in residential and commercial building sectors.

Electrochemical Synthesis of Cement

Electrochemical synthesis of cement uses an electrolyser-based process to decarbonate calcium carbonate while producing useful gas streams. This approach could enable the “green” production of cement, the world’s leading construction material. It would also eliminate a major source of global greenhouse gas emissions (8% of all emissions), which are created by the conventional production processes involving burning limestone with sand and clay. Once scaled up, clean cement production processes will transform the construction and adjacent sectors.
