Powering a Cleaner World: What's Driving Green Innovations in Energy, Transport, and Industry?
We all know that looking after our planet is super important. To build a future where our environment is healthy, we need green innovations. These are clever new ideas and technologies that help us:
Reduce greenhouse gas emissions: Lessening the gases that cause our planet to warm up too much (how to reduce greenhouse gas emissions).
Minimise pollution: Keeping our air, water, and land clean (ways to minimise pollution in industry).
Preserve natural resources and biodiversity: Protecting the Earth's valuable materials and the amazing variety of life on it (importance of preserving natural resources).
But where are we with these green innovations, and how are they different from other kinds of new ideas? This blog post will explore what’s happening in four key areas:
Green hydrogen: A clean fuel made from water using renewable energy (what is green hydrogen energy).
Green steel: Making steel without using fossil fuels, which cuts down on pollution (how is green steel produced).
Batteries: Better and cleaner ways to store energy for our devices and vehicles (advancements in battery technology).
Electric vehicles (EVs): Cars, trucks, and buses that run on electricity instead of gasoline or diesel (benefits of electric vehicles for the environment).
We’ll also look at what helps these green technologies grow and get used by more people and businesses (factors influencing green technology adoption).
The Speed of Green Innovation: Why Some Go Faster Than Others
Countries all over the world are working hard to cut carbon emissions and move towards cleaner economies (transitioning to a clean economy). In this big shift, innovation is playing a vital role. From green hydrogen production and low-emission steel manufacturing to the development of high-performance batteries and the increasing popularity of electric vehicles, the technologies that can help us clean up our energy, transportation, and factories are being created and put to use. However, they are not all moving at the same speed.
In some areas, like electric vehicles for personal transport and the development of advanced batteries, we’ve seen really fast progress in creating more sustainable solutions. These technologies are becoming more common and better all the time. On the other hand, green hydrogen as a widespread fuel source and green steel production at a large scale are still in the very early stages of development and haven't taken off as quickly.
Why this uneven progress? Which countries are leading the way in green technology innovation (countries leading in green technology)? And what else needs to happen to accelerate the green transition (how to accelerate the green transition), further reduce greenhouse gas emissions from industry and transport (reducing emissions from transport), significantly minimise pollution from manufacturing (minimising industrial pollution), and effectively preserve natural resources and biodiversity for the future (preserving biodiversity through innovation)? Let's take a closer look at these questions.
Green Innovation Across Four Key Sectors: A Snapshot
Green innovation isn't moving at the same pace for all clean technologies. While electric vehicles and battery technology for EVs have entered a period of rapid growth, green hydrogen production methods and sustainable steel manufacturing are still in the initial phases.
In 2023, it’s amazing to think that almost one out of every five cars sold worldwide was electric! This huge growth is the result of many years of government investment in green technology (public investment in EVs), strong competition among companies to make better EVs (private sector competition in EVs), and more and more people wanting to buy electric cars (rising consumer demand for EVs).
In contrast, low-emission hydrogen, which includes green hydrogen produced with renewables, accounted for only about 1% of all the hydrogen produced globally. And green steel production, made without the traditional high-emission methods, represents a tiny fraction – only around 0.05% – of the total steel produced around the world (challenges in scaling green steel).
To move forward on our green development goals (achieving green development goals), various innovation efforts are absolutely crucial. This includes:
Improving the safety of EVs and batteries: Making sure electric cars are safe and battery technology is reliable (EV battery safety improvements).
Enhancing the performance of battery technologies and their life cycles: Making batteries last longer, work better, and be used for other purposes after their first life in a vehicle (extending EV battery lifespan).
Developing new battery chemistries that reduce reliance on scarce critical minerals: Finding ways to make batteries with materials that are easier to get and less harmful to the environment (alternative battery materials).
Introducing innovations that improve possibilities for battery recycling: Creating better ways to take apart old batteries and reuse their valuable materials (advancements in battery recycling technology).
Green steel requires breakthroughs in production technologies: Finding new and cleaner ways to make steel on a large scale (innovative green steel production).
For green hydrogen, innovation is needed in areas such as electrolyser efficiency: Making the machines that produce hydrogen from water using electricity more effective (improving electrolyser efficiency).
Integration with renewable energy systems: Connecting hydrogen production directly with solar and wind power to make it truly green (integrating renewables with hydrogen production).
Safe storage and transport solutions: Finding better and safer ways to store and move hydrogen around (safe hydrogen storage and transport).
Innovation Beyond Technology: New Ways of Thinking and Doing
While technological progress is absolutely essential, it’s only part of the bigger picture. We also need non-technological innovation – new ways of doing things, new business models, and different choices that help us reduce our polluting habits (reducing polluting consumption patterns).
For example, with green hydrogen, moving it over long distances can be difficult and use a lot of energy. One potential solution is to move the energy-intensive industries that use hydrogen closer to where it’s produced. This doesn’t just require building new pipelines and storage facilities (infrastructure investment for green hydrogen) but also setting up entirely new green hydrogen supply chains (building green hydrogen supply chains).
When it comes to electric vehicles, making our transportation systems more sustainable requires more than just better EVs. We need innovations in urban and rural mobility services (sustainable transport solutions), including:
Smart urban planning: Designing our cities in ways that encourage walking, cycling, and the use of public transport (urban planning for sustainable transport).
Expanding electric micro-mobility options: Making it easier to use electric scooters, bikes, and other small electric vehicles (electric micro-mobility solutions).
Car-sharing platforms to maximise EV usage: Encouraging people to share electric cars, so fewer are needed overall (EV car-sharing benefits).
In the steel and batteries sectors, big improvements in recycling, reuse, and logistics are vital. Finding more efficient ways to collect and process steel scrap can significantly lower the emissions from making new steel (emissions reduction through steel recycling). Similarly, developing new strategies and business models for battery reuse (giving old EV batteries a second life in homes or businesses) and advanced battery recycling can reduce our need for new critical minerals for batteries (reducing reliance on critical minerals) and make our supply chains more secure (strengthening battery supply chain resilience).
Who Are the Green Innovators?
Looking around the world, certain places are playing a much bigger role in creating green innovations. Japan, the United States, South Korea, and the European Union (EU) – especially countries like Germany – are major centers for creating new green patents (leading countries in green patenting) and investing in green research and development (investment in green R&D).
China, on the other hand, has become a major global manufacturer of green technologies, particularly in the areas of green hydrogen production equipment (electrolysers), advanced battery manufacturing, and the production of electric vehicles (China's role in green technology manufacturing).
Within individual countries, the creation of green patents often happens in the same areas where patenting in general is concentrated. We’ve seen evidence of this pattern in both Germany and the United States, suggesting that existing centers of innovation are also becoming hubs for sustainable technology development (regional concentration of green innovation).
The growth of innovation ecosystems also benefits greatly from the interactions between established companies and new, smaller players. When disruptive actors enter the market with fresh ideas, it often pushes the larger, more traditional companies to innovate faster (impact of newcomers on green innovation). Furthermore, collaboration across different parts of the supply chain is crucial. For example, the interaction between companies that make batteries and electrolysers (upstream suppliers) and companies that use these technologies, like car manufacturers (downstream providers), has played a key role in moving green innovation forward (value chain interactions in green technology). The contributions of public research institutions and university researchers also provide essential knowledge and breakthroughs (role of public research in green innovation).
What Are the Roadblocks to Green Innovation?
Despite the clear progress we’ve seen in some areas, green innovation still faces some significant hurdles:
Not enough investment in green innovations: Often, the environmental damage caused by polluting technologies isn't fully reflected in their prices. This means that companies don't always have a strong enough financial reason to invest in developing cleaner alternatives. Also, uncertainties about new technologies, how the market will develop, and future regulations can make private companies hesitant to invest large sums (challenges in private investment in green tech).
Entrenched traditional technologies: Many industries have been using the same technologies for a long time, making it difficult and expensive to switch to greener options. This is especially true when it requires completely new infrastructure or a workforce with different skills (resistance to switching from traditional technologies). For example, we need more people with expertise in renewable energy systems and other green technology areas (skills shortage in green technology). Also, current consumer habits and preferences can sometimes make it harder for greener products and services to take off (consumer behaviour as a barrier to green tech).
Higher costs of green products: Often, green products cost more to produce than their more polluting alternatives. This can make it hard for consumers and businesses to choose the greener option, even if they want to (cost competitiveness of green products). We see this across all four sectors we’ve looked at, although the price difference is gradually getting smaller for EVs and batteries (narrowing cost gap for EVs). For EVs to be as convenient as gasoline cars, we also need a much larger network of EV charging infrastructure (expansion of EV charging infrastructure).
Sector-specific supply-side challenges: Different industries face their own unique challenges. For example, making green steel requires huge upfront investments (high capital investment for green steel). Steelmaking plants also have very long lifespans (around 50 years), which means companies are less likely to replace them quickly. Additionally, the fact that there’s already too much steel being produced globally reduces companies’ profits and their ability to invest in green steel production technologies (impact of steel overcapacity on green innovation). For the car industry, switching from traditional cars to EVs requires reskilling the workforce (workforce reskilling for EV production) and building entirely new supply chains for things like batteries, while also moving away from the need for traditional car parts like transmissions (shifting away from ICE car components).
