2014 Global Summary of Five Major Scientific and Technological Achievements in Energy Conservation and Emission Reduction

As the energy-saving and environmental protection industry continues to grow, global companies are constantly innovating their technologies to maximize energy efficiency. With advancements in energy-saving techniques steadily advancing, here’s a roundup of recent innovations from both domestic and international markets.

Hunan has completed China's first hydrogen peroxide-to-propylene oxide plant. The project, a key initiative under Sinopec's "Ten Dragon" program and the country's first domestically developed hydrogen peroxide-to-propylene oxide unit, was successfully built at the Changling Refining & Chemical Complex in Hunan. With a designed production capacity of 100,000 tons per year, the facility is expected to generate annual sales revenue exceeding 1.1 billion yuan once operational.

Propylene oxide is widely used in industries such as chemicals, agrochemicals, textiles, and personal care products, making it a crucial basic chemical feedstock. The direct oxidation of hydrogen peroxide to produce propylene oxide is an emerging, environmentally friendly production process. Compared to traditional methods like the chlorohydrin process, this method boasts advantages such as lower energy consumption and reduced pollution, with virtually no industrial wastewater discharged.

In a context where a few foreign companies hold technological monopolies and face immense challenges in technology transfer, Changling Refining & Chemical Co., Ltd., in collaboration with the Research Institute of Petrochemical Sciences, Hunan Changling Petrochemical Technology Development Co., Ltd., Sinopec Shanghai Engineering Co., Ltd., and Qingdao Safety Engineering Research Institute, successfully developed this process independently—breaking the foreign monopoly on this green and environmentally friendly technology.

In 2010, the process moved out of the design room and into industrial-scale trials, with results showing that all technical indicators met the design specifications—and some even surpassed international standards.

In 2012, the technology was approved by Sinopec Corporation and subsequently entered the pilot production phase.

In January 2013, construction began on the 100,000-ton-per-year hydrogen peroxide-to-propylene oxide unit at Changling Refining & Chemicals. The Project Management Department meticulously planned and coordinated, implementing a robust safety management and assurance system, as well as standardized, procedural construction practices. Despite multiple design changes, tight equipment procurement schedules, and significant challenges in construction coordination, the project achieved an impressive milestone: no recordable safety incidents during its first million man-hours of safe construction.

Germany's standard passive energy-efficient homes have arrived in Jinan. Recently, three pilot projects featuring Germany-standard passive ultra-low-energy buildings—commonly known as "passive houses"—were officially established in the city. The three pilot projects selected by Jinan include the Disaster Prevention and Emergency Command Center in Quancheng Park, a teaching and experimental center at Shandong University of Architecture, and an educational facility at Shandong Urban Construction College. All three projects will strictly adhere to Germany's renowned passive house construction standards.

Also confirmed were eight additional pilot projects across the province, bringing the total number of these initiatives to 11. These 11 projects will receive a subsidy of 60 million yuan from the provincial treasury. Many in the industry likely still remember the catchy slogan "Say goodbye to the era of air conditioning and heating," which highlighted the innovative concept of maintaining comfortable indoor temperatures without relying on conventional heating or cooling systems. Back in 2002, Beijing Fengshang Real Estate took the lead by introducing this vision at the Fengshang International Apartments, located in the Wanliu area of Haidian District. This development became the first residential building in China designed and constructed using Europe’s advanced, eco-friendly design principles focused on high comfort and minimal energy consumption. The project integrated five key systems—concrete-based heating and cooling, a healthy fresh-air ventilation system, an optimized exterior wall system, cutting-edge window technology, and a state-of-the-art rooftop system—to create an ecological apartment complex. By doing so, it not only ensured exceptional living comfort but also enabled the sustainable reuse of renewable resources while significantly reducing energy usage.

These benchmark energy-efficient buildings once sent ripples of excitement through China's real estate industry. Since then, low-energy-consumption architecture has gradually come into the public eye. Yet, over the past decade or more, there have been few reports in China about zero-energy or passive-building designs—practices that remain largely shrouded in mystery, with actual implementations often kept discreetly out of sight, leaving many feeling both intrigued and somewhat overwhelmed by the challenge ahead.

A so-called "passive" house is one that achieves comfortable indoor temperatures without relying on air conditioning or heating systems. Throughout China's thousands-of-year history of construction, our ancestors' practices—such as digging earth caves and living in tree dwellings—were essentially early forms of passive housing.

Unlike traditional projects, passive house designs employ construction methods that differ significantly from conventional building practices to achieve exceptional insulation and airtightness. For instance, while typical projects usually rely on a 5-centimeter-thick insulation layer, passive houses boast insulation layers measuring a robust 20 to 25 centimeters. Another example: when installing solar water heater brackets, builders first place two layers of insulation underneath to ensure secure attachment—preventing any unwanted heat loss. Even the windows are custom-made, featuring triple-glazed units. Interestingly, even elements like wall-mounted electrical outlets inside the rooms undergo specialized treatment to enhance both insulation and airtightness. Thanks to these cutting-edge technologies and design innovations, passive houses can achieve energy savings of over 90% compared to today’s standard construction projects.

Boston Battery: Driving New Energy Bus Development with "Space-Quality" Standards Boston Battery, a global leader in next-generation ternary lithium battery technology for new energy vehicles, initiated bus battery testing last year in Hohhot, Inner Mongolia, and Xiangfan, Hubei Province. During these real-world trials, Boston’s battery products were rigorously tested under extreme weather conditions ranging from -20°C to 34°C—enduring both scorching heat and freezing cold. According to an internal report from Boston Battery, the company’s buses in Hohhot underwent testing across two seasons—summer and winter. In summer, a single charge enabled a range of up to 280 kilometers (SOC: 99% to 25%), while in winter, the range extended to 258 kilometers (SOC: 95% to 30%). These results clearly demonstrate that the batteries fully meet the demands of urban public transportation. Notably, throughout all driving conditions, the voltage difference among individual battery cells never exceeded 100mV, highlighting the system’s exceptional stability and performance. Meanwhile, during battery pack testing in Xiangfan, after more than 14,000 kilometers of regular operation, technicians from the bus company inspected the battery compartments—and found no signs of contamination inside. This underscores Boston Battery’s outstanding performance in terms of sealing and protective measures, further solidifying its reputation as a reliable and cutting-edge solution for sustainable mobility.

Recently, Boston Power successfully completed NASA’s rigorous space testing. According to the test report, Boston Power’s batteries demonstrated "aerospace-grade" performance in critical areas—including charging and discharging, shock resistance, and the battery’s secure, airtight design—under challenging, simulated space conditions that closely mimic the harsh realities of outer space. NASA’s stringent battery selection process evaluates not only safety under extreme scenarios but also meticulous quality control and consistent manufacturing standards. During the testing phase, NASA randomly selected multiple batches of batteries directly from the production line for thorough evaluation. Boston Power’s batteries stood out for their exceptional consistency, earning high praise from the agency.

German industry giants join forces to launch the construction of a rapid-charging network, aiming to accelerate the adoption of electric mobility. To drive forward the development of electric transportation, a comprehensive network of charging stations will be built in major metropolitan areas and along key transport routes. Germany’s BMW, Daimler, Porsche, and Volkswagen, along with energy provider EnBW, the German Cooperative Publishing Group, and two prominent German universities, have jointly unveiled a major project called "SLAM – Rapid-Charging Network."

Within the framework of this project, the plan is to complete the construction of 400 AC and DC fast-charging stations by 2017. These stations will be designed to deliver 80% of a vehicle’s battery capacity within just 30 minutes, and they will feature the European-standard CCS connectors, making them compatible with all vehicles equipped with this system. As a pilot initiative, the company will invest in setting up at least 20 fast-charging stations around select banks by the end of September this year, aiming to gauge public acceptance and feedback.

Japanese farmers are boosting their income by "growing" electricity alongside their vegetable crops—increasing it tenfold! Typically, you’d spot scarecrows in fields to keep birds and pests at bay, but in Ichihara City, Chiba Prefecture, in the Kanto region of Japan’s main island of Honshu, the scene is entirely different: neatly arranged rows of poles support staggered, lead-gray solar panels that aren’t there to ward off birds. Upon closer inspection, you’ll notice these aren’t ordinary scarecrows—they’re actually solar panels! This 750-square-meter farm has been equipped with 348 solar panels, mounted atop sturdy metal pipes and elevated 3 meters off the ground, with 5-meter gaps between each row. To maximize energy production, the panels can even adjust their tilt angle depending on the season—switching from about 40 degrees in winter to roughly 25 degrees in summer, ensuring optimal sunlight exposure year-round.
