Energy & Decarbonization

Biofuels and e-fuels have been on the rise as many sectors worldwide aim to increase sustainability, with traditional aviation using fossil-based jet fuel contributing around 2.5% of global CO₂ emissions. Conventional aviation fuel (Jet A-1) can now be blended with or replaced by new sustainable fuel derived from biomass or electricity. The main advantage of these replacement fuels is repurposing waste products from other industries into useful products, with SAF reducing flight emissions from its production to end use, anywhere from 30% to 90% in best-case scenarios.

Scope 3 emissions (indirect greenhouse gas emissions that occur in a company's value chain but are not produced by the company itself) are hard to quantify and even harder for businesses to reduce. The embodied carbon from construction can often be a significant contributor, with most of this CO2 coming from the cement used. This article explores three new green cement solutions that are increasingly enabling companies to decrease scope 3 CO2 emissions.

The stationary fuel cell market is set to reach US$8bn by 2035. In this short video, IDTechEx Technology Analyst Maia Benstead talks through the dominant technologies, the alternatives competing for market share and the application areas for stationary fuel cells.

With growing concerns over energy security due to rising power demands and greater decarbonization targets, stationary fuel cells have garnered attention as alternative green power generation devices. But with various sectors aiming for decarbonization, which fuel cells will fit the mark, and which applications will be key to their success?

A free collection of insights from our industry experts, sharing some of the key technology innovation trends shaping the next decade.

By 2035, IDTechEx forecasts that the continued growth of artificial intelligence will result in over 2000 TWh of energy being consumed by data centers. The expected increase in CO2 emissions from powering these new data centers creates a dual challenge for both governments with net-zero targets and tech giants with internal carbon neutrality pledges alike: how can the unprecedented rise of AI be supported without causing major harm to the environment?

The growing availability of retired EV batteries will be a critical factor that will influence the growing penetration of second-life battery storage technologies. However, key considerations related to EV battery chemistry and repurposing processes will dictate how techno-economically feasible it will be to develop and deploy these technologies at commercial-scale and how competitive they will be compared to incumbent first-life Li-ion battery energy storage systems (BESS).

The aviation industry encompasses a diverse range of aircraft types and sizes, each with unique use cases and vastly different power and energy requirements. In this brief video, Dr. James Jeffs, Principal Technology Analyst at IDTechEx, explains more about what this means for the future of sustainable aviation.

Solar power is one of the fastest growing renewable energy technologies. In 2023 alone, over 340 GW of new solar power was installed. With rising energy demands, concerns over energy security, and increasing decarbonization goals, solar power installations are only anticipated to rise.
