With record-breaking carbon credit sales in 2024 and increasing overlap of voluntary and compliance carbon markets, the business case for carbon dioxide removal is growing stronger. IDTechEx forecasts the carbon credit market revenue from durable, engineered carbon dioxide removal technologies will exceed US$14 billion in 2035.

The renewable energy landscape is evolving rapidly, with solar power leading the way. In 2023, global investments in solar energy reportedly surpassed all other power generation sources—including oil—for the first time. This article details the major growth factors for the thin film photovoltaics market, including the emerging technologies and application areas.

Photovoltaic technologies are gaining momentum as a result of solar power being one of the fastest-growing renewable energy sources across the world. In 2021, solar installations were seen to overtake wind generation, and in 2023, approximately 450GW of new solar capacity was recorded.

Automotive and battery OEMs are responsible for collecting retired batteries, which is where the second-life battery value chain begins. Recycling processes may see critical raw materials such as lithium, cobalt, and nickel reclaimed by OEMs. However, the already somewhat established relationship between recyclers and manufacturers may prove tricky for repurposing companies to interrupt.

Data centers can be likened to an ecosystem of computing facilities that contain many facets required to store and handle data. IDTechEx's latest report, "Sustainability for Data Centers 2025-2035: Green Technologies, Market Forecasts, and Players", unpacks efforts being made in the data center sector towards increased sustainability in response to the rising CO2 emissions from the development of AI.

Key trends are emerging that suggest where the second-life battery market will develop and what applications these technologies will be used for. As written in their recently updated market report, "Second-life Electric Vehicle Batteries 2025-2035: Markets, Forecasts, Players, and Technologies", IDTechEx predicts that by 2035, the global second-life EV battery market will be valued at US$4.2 billion.

Germany has one of the strongest battery energy storage systems (BESS) potential worldwide, with an already large uptake of residential battery storage, meaning market growth is set to succeed within the next decade.

Public awareness of PFAS (per- and polyfluoroalkyl substances) is hitting a new high as headlines concerning "forever chemicals" continue to appear in prominent news outlets. Whether it be news about PFAS bans in different industries, lawsuits against PFAS manufacturers and users, detection of PFAS in various locations and products, and treatment of PFAS in drinking water, there is no doubt that for many, PFAS is one of the foremost health issues of the 2020s.

The advancement of fuel cell technologies, combined with the global commitment to sustainable aviation, creates a significant opportunity for hydrogen-fuelled planes to enhance the sustainability of air travel.

Silicon-based solar technologies continue to dominate the market; however, there is rising interest in an emerging technology known as perovskite. Perovskites have the potential to enhance existing silicon solar supplies, but which applications can perovskite solar be used for, and how will it compete in a market dominated by an already well-established technology?

IDTechEx forecasts that by 2035, the global data center sector will have saved US$150 billion by using low-carbon energy sources compared to a fossil fuel scenario (taking 2024 as the baseline). Some emerging energy technologies expected to play an increasingly important role are explored in this article.

As growing numbers of countries identify critical materials within their economies, the ability to recycle them is becoming increasingly important, especially considering both their economic importance and ongoing supply risks. Sustainability goals rely on growing technology sectors like electric vehicles, which rely on magnets to be manufactured, ultimately meaning sourcing and recycling critical materials is an economic necessity to keep supply chains running.

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.
