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.

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?
