At WindEnergy Hamburg, CRRC Corporation Limited (CRRC) is demonstrating its innovative line-up of wind-solar-hydrogen-storage integration solutions, attracting visitors to Booth 241 in Hall B7 of the Hamburg Messe und Congress. The exhibit highlights how CRRC’s technology seamlessly connects wind and solar power to the urban grid, utilizing a booster station to transfer electricity. Surplus energy is either stored in an energy storage system or used for hydrogen production, showcasing a green, low-carbon, and sustainable ecosystem.
CRRC’s comprehensive renewable energy portfolio encompasses wind, solar, hydrogen production, and energy storage. With its complete wind turbines as the foundation, CRRC has built a robust technology and industry chain that encompasses all facets of clean electricity – from generation to transmission, distribution, and usage. The company is well-equipped to offer tailored wind-solar-hydrogen-storage integration solutions for diverse scenarios, accelerating the global transition towards carbon peaking and neutrality.
A Comprehensive Wind and Solar Power Industry Chain
China’s substantial role in the expansion of wind energy worldwide is evident in the fact that in 2023, 60% of all new wind power capacity added globally came from China. CRRC, a pioneer in China’s wind power equipment manufacturing sector, boasts a complete industry chain and a wide range of products. The company has successfully established an industrial cluster for wind power equipment, encompassing complete wind turbines, generators, blades, tower barrels, converters, gearboxes, transformers, and more. CRRC offers over 80 models, with flagship products spanning 1.5 MW to 12 MW for onshore applications and 8 MW to 20 MW for offshore applications. Its capabilities in equipment development, design, and manufacturing are among the world’s best, serving over 260 wind farms globally with a total installed capacity exceeding 13,000 units.
In April of this year, Brinckmann (BM), a leading global renewable energy consulting and research firm, announced the market share rankings for the top four component manufacturers in wind turbine blades, gearboxes, converters, and generators. CRRC secured the top global position for wind generators.
Beyond wind power, CRRC has made significant strides in the PV industry. Leveraging its core technologies from the rail transit sector, such as system integration, converters, and control systems, CRRC has developed a series of centralized and string inverters, with over 50GW delivered cumulatively. These offerings are suitable for diverse environments ranging from large-scale desert and mudflat power plants to industrial and commercial rooftops, and are used in over 20 countries worldwide.
Hydrogen Energy and Energy Storage: Flexibility, Safety, Efficiency
The rapid growth of renewable energy sources, such as wind and solar, has positioned green power-to-hydrogen as a crucial solution to address the volatility and intermittency of these resources. CRRC’s flexible green power to hydrogen system maintains a dynamic balance between hydrogen production load and wind-solar generation capacity. Utilizing wind-solar forecasting, energy scheduling, cluster control, and gas-liquid regulation, the solution embodies flexibility, safety, efficiency, and intelligence. It offers optimal system-level benefits for multiple renewable energy hydrogen production scenarios, including AC/DC, grid connection/stand-alone, and others.
Energy storage is essential for the development of renewable energy and is a key element of the new power system. It stores and releases energy, reduces wind and solar curtailment, manages peak demand, and enhances power supply reliability. CRRC has introduced the 5.X liquid-cooling energy storage system, featuring a 5 MWh single-cabin capacity and 99% maximum converter efficiency. The system ensures superior safety, longevity, and reliability.
As a global energy technology leader, CRRC is committed to spearheading technological advancements, driving the evolution and upgrading of renewable energy technologies, and contributing to the global energy transition towards a cleaner, more beautiful Earth.
