Hydrogen engines offer a fundamentally different approach to decarbonizing transport. IDTechEx Technology Analyst Mika Takahashi explains more about the technology in this short video.

Global demand for low-carbon cement is increasing. Government regulation for low-carbon cement production is strongest in the European Union, and the US government has been particularly active in green public procurement. Private sector demand is growing, and the advent of book and claim systems could accelerate this market even further.

Thursday 9 January 2025 - Navigating Emerging Trends for the Economic Development of Second-Life EV Batteries; Applications of second-life electric vehicle batteries; Overview of the global second-life electric vehicle battery market, including commentary on key players, regional activity, and an introduction to policies; Discussion on cost bottlenecks identified by IDTechEx in the second-life battery repurposing process, informed by primary interviews with key repurposers; Emerging trends to impact repurposing costs and economic development of second-life EV batteries. This includes business-to-business (B2B) battery marketplaces, advanced battery testing / grading / diagnostics technologies, semi-automated EV battery disassembly technologies, EV battery trends, and revenue sharing business models; IDTechEx's outlook and conclusions on the global second-life EV battery market

IDTechEx forecasts the second-life EV battery market to grow to US$4.2B in value by 2035, given the increasing availability of retired EV batteries over the coming decade. Li-ion batteries in electric vehicles may be used for 6-15 years, depending on the application and their degradation over time. Once these batteries reach a capacity, or State-of-Health (SOH), that is too low to facilitate the driving range requirements of the EV, these are retired. These batteries could be recycled to reclaim critical and valuable raw materials, which could be reintroduced into new EV battery manufacturing.

The e-fuels sector stands at a critical juncture in its evolution from laboratory innovation and demonstration projects to industrial-scale production. While significant progress has been made in technology development and market interest, evidenced by substantial corporate investments and supportive policy frameworks, considerable challenges remain.

IDTechEx predicts the stationary fuel cell market is expected to grow with a CAGR of 16.7% between now and 2035, with targets in place in countries worldwide to help achieve maximum growth and deployment of fuel cell technology. Despite the hype of low carbon benefits attached to fuel cells, this is only applicable when green hydrogen is used, with other gases producing carbon as a by-product of their sourcing, or reaction process within the fuel cell.

Industrial Internet of Things sensor technology (IIoT) seeks to enable greater industrial automation, improved worker safety, and streamlined maintenance planning. From cameras, LiDAR, and radar for machine vision in robotics, to skin patches and miniaturized gas sensors in smart personal protection equipment, emerging IIoT applications present growth opportunities for a variety of sensor technologies.

IDTechEx projects that the annual water electrolyzer market will exceed US$70 billion by 2034. However, access to more low-cost renewable electricity and stronger policy support for green hydrogen is needed to make it more competitive in various applications.

IDTechEx predicts that the annual demand for stationary fuel cells in the commercial market will surpass 1.9GW by 2035, with the main applications being in residential, industrial, utilities, commercial, and data sectors. Currently, over 80% of power worldwide is still obtained from fossil fuels, meaning there is lots of opportunity for growth and expansion of sustainable energy sourcing, with large demand and potential for fuel cells.

Friday 13 December 2024 - Building Towards Net-Zero: Which Technologies Can Decarbonize Cement? Discussion of key drivers and barriers for cement sector decarbonization, including stimulating public sector and private sector demand; Benchmarking the most impactful cement decarbonization technologies over the coming decade (leading supplementary cementitious materials, biomass-based fuels, waste-derived fuels, and CCUS), alongside emerging cement decarbonization technologies (new cement production processes and materials, kiln electrification, concentrated solar power, hydrogen); Contextualizing the impact of cement decarbonization technologies in 2035 within global progress towards net-zero by 2050

Achieving net zero by 2050 will require approximately 30 gigatonnes less CO2 to be emitted each year, alongside 2-10 gigatonnes of CO2 removal per year. CCUS has been recognized by many global bodies, including the Intergovernmental Panel on Climate Change and the International Energy Agency, as a great decarbonization tool to help achieve these goals.

Haptics might fly under the radar, but they form a major industry that offers serious user experience benefits to consumers. IDTechEx forecasts a US$7.1 billion market for haptic technology in 2035, with much of the growth in this market being fueled by the adoption of haptics in new classes of device.

As global populations rise and more regions urbanize, cutting back on construction isn't a viable decarbonization strategy. Leading cement decarbonization technologies, including supplementary cementitious materials, alternative fuels, and carbon capture, will avoid an additional 422 million tonnes of CO2 emissions, in the cement sector over the coming decade.

If H2ICE offers significant emissions reductions, can be done quickly, and does not compromise on performance and range (essential metrics for commercial vehicles), then what is holding it back?

With growing interest into the integration of fuel cells for stationary power, many commercial players have chosen to adopt either proton exchange membrane (PEM) or solid oxide fuel cells (SOFC). However, alternative fuel cell technologies like alkaline fuel cells (AFCs), molten carbonate fuel cells (MCFCs), phosphoric acid fuel cells (PAFCs) and direct methanol fuel cells (DMFCs) still compete for market share.

Across the globe, over 140 countries have set a net-zero target, with many committed to reaching net-zero CO2 emissions by 2050. This Herculean task will require many emission reduction technologies in tandem - and the groundwork must be laid now. CCUS (carbon capture, utilization, and storage) solutions have been identified as one such vital tool with the ability to decarbonize existing industry assets.

Utilizing alternatives to helium where possible could allow for a greater conservation of helium, which could prove to be necessary for the market going forward. IDTechEx reports that since 2005, there have been 4 supply shortages of helium, each resulting in high price volatility, with the price of helium having almost doubled since 2021.

As the world grapples with the environmental impact of traditional plastics, bioplastics derived from carbon dioxide (CO2) and waste materials present a promising solution. This emerging sustainable market seeks to address two critical global challenges: reducing greenhouse gas emissions and managing waste.

Electric vehicles (EVs) have seen tremendous growth historically, but growth has slowed somewhat in 2024. The goal of automakers is to reduce the cost of making EVs, both to improve their profit margins on existing vehicles and to make lower-cost models more feasible.
