Wind power is another rapidly growing renewable energy source. Innovations in turbine design, such as larger rotor diameters and taller towers, are increasing the efficiency of wind farms. Offshore wind power is particularly promising, as it can harness stronger and more consistent winds. Europe is at the forefront of offshore wind development, with large-scale projects in the North Sea and Baltic Sea. Floating wind turbines are also being developed, which can be deployed in deeper waters and open up new areas for wind energy development. For example, Scotland is a leading country exploring floating wind turbine technology.

Hydropower

Hydropower has been a long-established source of renewable energy, but innovations are focusing on minimizing its environmental impact. Run-of-river hydropower projects, which divert a portion of a river's flow to generate electricity, can reduce the impacts on fish migration and river ecosystems compared to traditional dam projects. Pumped hydro storage, which uses excess electricity to pump water to a higher reservoir and then releases it to generate power when needed, is also an important technology for grid-scale energy storage.

Geothermal Energy

Geothermal energy harnesses heat from the Earth's interior to generate electricity and provide heating. Enhanced geothermal systems (EGS) are being developed to access geothermal resources in areas where conventional geothermal reservoirs are not available. EGS involves injecting water into hot, dry rocks deep underground, which fractures the rocks and creates a pathway for the water to circulate and extract heat. Iceland is a world leader in geothermal energy, using it to generate electricity and heat homes and businesses.

Carbon Capture, Utilization, and Storage (CCUS)

Carbon capture, utilization, and storage (CCUS) technologies are designed to capture carbon dioxide (CO2) emissions from industrial sources or directly from the atmosphere and then either utilize the CO2 or store it permanently underground. CCUS is considered a crucial technology for reducing emissions from hard-to-abate sectors, such as cement and steel production.

Carbon Capture Technologies

Various technologies are available for capturing CO2, including post-combustion capture, pre-combustion capture, and oxy-fuel combustion. Post-combustion capture involves separating CO2 from flue gas after combustion. Pre-combustion capture involves converting fuel into a mixture of hydrogen and CO2 before combustion, which allows for easier separation of the CO2. Oxy-fuel combustion involves burning fuel in pure oxygen, which produces a flue gas consisting primarily of CO2 and water vapor.

Carbon Utilization

Captured CO2 can be utilized in a variety of ways, including enhanced oil recovery (EOR), where CO2 is injected into oil reservoirs to increase oil production. CO2 can also be used to produce chemicals, fuels, and building materials. For example, some companies are developing technologies to convert CO2 into polymers, which can be used to make plastics. Others are using CO2 to produce synthetic fuels, such as methanol and jet fuel. These technologies offer the potential to create new markets for CO2 and reduce the demand for fossil fuels.

Carbon Storage

If CO2 is not utilized, it can be stored permanently underground in geological formations, such as deep saline aquifers or depleted oil and gas reservoirs. The CO2 is injected into these formations and trapped by impermeable layers of rock. Monitoring is essential to ensure that the CO2 remains securely stored and does not leak back into the atmosphere. Norway has been a pioneer in carbon storage, with the Sleipner project storing CO2 in a deep saline aquifer since 1996.

Sustainable Agriculture and Land Use

Agriculture and land use are significant contributors to greenhouse gas emissions, accounting for approximately 24% of global emissions. Innovations in sustainable agriculture and land management practices are essential for reducing emissions and enhancing carbon sequestration.

Precision Agriculture

Precision agriculture uses sensors, drones, and data analytics to optimize crop yields and reduce the use of inputs such as fertilizers and pesticides. By precisely targeting inputs to where they are needed, precision agriculture can reduce emissions from fertilizer production and application. For example, in the United States, farmers are using precision agriculture techniques to reduce fertilizer use and improve water management.

Conservation Agriculture

Conservation agriculture practices, such as no-till farming, cover cropping, and crop rotation, can improve soil health, reduce erosion, and increase carbon sequestration. No-till farming involves planting crops directly into the soil without tilling, which reduces soil disturbance and carbon emissions. Cover cropping involves planting crops between harvest and planting to protect the soil and improve its fertility. Crop rotation involves planting different crops in sequence to improve soil health and reduce pest and disease pressure. These practices are being adopted in many parts of the world, including South America and Africa, to improve agricultural sustainability.

Agroforestry

Agroforestry involves integrating trees and shrubs into agricultural systems. Trees can sequester carbon, provide shade for crops and livestock, and improve soil health. Agroforestry systems can also provide additional income for farmers through the sale of timber, fruits, and nuts. In many tropical countries, agroforestry is a traditional practice that is being promoted to enhance carbon sequestration and biodiversity.

Sustainable Livestock Management

Livestock production is a significant source of greenhouse gas emissions, particularly methane. Innovations in livestock management practices, such as improved feeding strategies and manure management, can reduce emissions. For example, feeding livestock seaweed or other supplements can reduce methane emissions. Manure digesters can capture methane from manure and use it to generate biogas, which can be used for electricity or heating. New Zealand is a global leader in researching and implementing sustainable livestock management practices.

Climate-Resilient Infrastructure

Climate change is increasing the frequency and intensity of extreme weather events, such as floods, droughts, and heatwaves. Climate-resilient infrastructure is designed to withstand these impacts and ensure the continued provision of essential services.
