New En­ergy in Full Swing

Beijing (English) - - CONTENTS - Trans­lated by Wang Hui­hui Edited by Noah We­ber Pho­tos cour­tesy of Bei­jing Ori­en­tal En­ergy Tech­nol­ogy Co., Ltd. and Xin­jiang Gold­wind Sci­ence & Tech­nol­ogy Co., Ltd.

Un­like the pre­vi­ous two en­ergy rev­o­lu­tions, the rise of new en­ergy en­ables China to be­come a ma­jor pro­moter of a third en­ergy revo­lu­tion.

Take a drive through the Bei­jing Eco­nomic-tech­no­log­i­cal De­vel­op­ment Area (BDA) and you’ll brush past count­less mod­ern build­ings. With only a quick glance, one is able to ver­i­ta­bly smell the sen­sa­tion of tech­nol­ogy. Tall wind­mills along the roads stand like strap­ping guards in the fields, trans­form­ing wind en­ergy into elec­tric­ity, and guarding a piece of Bei­jing’s blue sky. So­lar pan­els line the roofs like an ocean of blue, har­ness­ing the gift of the sun, and pass­ing its warmth on to the peo­ple.

In re­cent years, a his­toric en­ergy revo­lu­tion has been tak­ing shape world­wide. New forms of en­ergy—pri­mar­ily wind and so­lar power— have de­vel­oped rapidly, of­fer­ing a chal­lenge to tra­di­tional forms of en­ergy such as oil and coal. In 2015, the in­stalled ca­pac­ity of re­new­able en­ergy gen­er­a­tors ex­ceeded that of con­ven­tional en­ergy gen­er­a­tors for the first time. A to­tal of 173 coun­tries have set their own goals for new en­ergy de­vel­op­ment, and the pro­por­tion of new en­ergy con­sump­tion within the to­tal en­ergy con­sump­tion con­tin­ues to rise. The Euro­pean Union plans to in­crease the pro­por­tion of its non­fos­sil en­ergy con­sump­tion to 75 per­cent of its to­tal en­ergy con­sump­tion by 2050. Swe­den and other coun­tries have pro­posed to achieve 100 per­cent re­new­able en­ergy-gen­er­ated elec­tric­ity by around 2040. The Chi­nese govern­ment has made clear that by 2030, non-fos­sil en­ergy will ac­count for 50 per­cent of its to­tal elec­tric­ity. Un­like the pre­vi­ous two en­ergy rev­o­lu­tions, the rise of new en­ergy in China en­ables China to be­come a ma­jor pro­moter of this third en­ergy revo­lu­tion.

Pho­to­voltaic Ocean

Bei­jing Ori­en­tal En­ergy Tech­nol­ogy Co.,

Ltd. (BOE Smart En­ergy) is a wholly-owned sub­sidiary of BOE Tech­nol­ogy Group Co., Ltd., which spe­cialises in new en­ergy busi­ness. Es­tab­lished in 2009, BOE Smart En­ergy is China’s first en­ter­prise to en­gage in new en­ergy ser­vices and so­lu­tions, com­mit­ted to be­com­ing a global leader in the en­ergy-based In­ter­net of Things (IOT). Against the back­ground of sup­ply­side en­ergy re­form, new modes of en­ergy pro­duc­tion and con­sump­tion are achieved through dis­trib­uted en­ergy, smart grids, and com­ple­men­tary en­ergy forms.

“We have many new en­ergy power plants, and most of them are pho­to­voltaic power plants in­stalled on roofs. Bei­jing’s first roof pro­ject ‘Golden Sun’ was built by us,” said Song Hang­bin, gen­eral man­ager of BOE Smart En­ergy. Stand­ing on the roof of the plant of the BOE Gen­er­a­tion 8.5 TFT-LCD in BDA, Song pointed at the so­lar pho­to­voltaic pan­els, call­ing them the BOE Gen­er­a­tion 8.5 TFTLCD Fac­tory Pho­to­voltaic Power Gen­er­a­tion Pro­ject. The pho­to­voltaic power sta­tion oc­cu­pies an area of 113,000 square me­tres on the roof, and it is the largest in­dus­trial plant roof demon­stra­tion pro­ject among China’s 13 pho­to­voltaic power gen­er­a­tion demon­stra­tion ar­eas. The to­tal in­stalled ca­pac­ity of the pro­ject is about 5,000 kilo­watts (kw), with over 21,000 bat­tery pan­els of 235 watts ( W) pro­duced by Yingli. It can gen­er­ate more than 6 mil­lion kilo­watts-hour (kwh) of elec­tric­ity ev­ery year, sav­ing 1,900 tons of stan­dard coal, and re­duc­ing the emis­sion of car­bon diox­ide by about 5,800 tons, equiv­a­lent to plant­ing 17 hectares of broad-leaved for­est. The pro­ject rep­re­sents not only BEO’S prac­tice of “green man­u­fac­tur­ing,” but also the ef­forts of Bei­jing mu­nic­i­pal govern­ment to ad­just its en­ergy struc­ture and de­velop re­new­able en­ergy, play­ing an ac­tive role in pro­mot­ing the ap­pli­ca­tion and pop­u­lar­i­sa­tion of pho­to­voltaic power gen­er­a­tion.

China’s so­lar plants are built on bar­ren hills not suit­able for grow­ing crops, on low­ly­ing lakes not suit­able for fish-farm­ing, and on the roofs of build­ings. Pre­vi­ously, new en­ergy had noth­ing to do with Chi­nese farm­ers. But now, the govern­ment has sup­ported some projects and helped farm­ers in­stall so­lar en­ergy equip­ment on their roofs. In Jiangsu, Zhe­jiang and other de­vel­oped ar­eas, peo­ple pay to in­stall so­lar pho­to­voltaic pan­els, and the govern­ment also pro­vides them sub­si­dies. Pre­vi­ously in north­ern China, farm­ers would burn coal for heat, but fol­low­ing “coal-to­elec­tric­ity” en­ergy re­form, ther­mal in­su­la­tion walls and so­lar water heaters have been in­stalled. To­day, hot water supplied by so­lar water heat­ing sys­tems is avail­able in most ru­ral ar­eas of north­ern China.

In densely pop­u­lated ar­eas short on land re­sources, new en­ergy is de­vel­oped in a smallscale and dis­trib­uted man­ner. In deserts, new en­ergy is de­vel­oped in a large-scale and in­ten­sive man­ner. In China’s nat­u­ral con­di­tions the lat­ter mode pre­vails. In Gansu and In­ner Mon­go­lia, the av­er­age util­i­sa­tion time of wind and elec­tric power reaches over 3,000 hours per year, and the av­er­age an­nual pho­to­elec­tric util­i­sa­tion time reaches over 2,000 hours in Ti­bet and Qing­hai— both are higher than those of the eastern and cen­tral ar­eas (about 500–1,000 hours). There­fore, western ar­eas are most suit­able for build­ing 10 mil­lion-kw new en­ergy bases.

Aside from pho­to­voltaic power projects, BOE Smart En­ergy also pro­vides pho­to­voltaic busi­ness, en­ergy-sav­ing ser­vices, smart mi­cro­grids, trans­ac­tion busi­ness and a plant fac­tory. It has more than 30 patents in the field of new en­ergy, and in­vests in the re­search and de­vel­op­ment of elec­tric­ity sale and distri­bu­tion, en­ergy stor­age, and car­bon trad­ing. Based on its pho­to­voltaic power plants, BOE works to ac­tively de­velop the en­ergy In­ter­net. The ca­pac­ity of BOE Smart En­ergy’s pho­to­voltaic power plants is ex­pected to reach 4 gi­gawatts (gw) in 2020, and these pho­to­voltaic power plants will pro­vide a to­tal of 110 bil­lion kwh of clean elec­tric­ity. Com­pared with coal-fired power plants, pho­to­voltaic power plants have the ad­van­tages of sav­ing stan­dard coal, re­duc­ing air pol­lu­tant emis­sions (sul­phur diox­ide, ni­tro­gen ox­ide and car­bon diox­ide), sav­ing en­ergy, pro­tect­ing the en­vi­ron­ment and gen­er­ally ben­e­fit­ing so­ci­ety.

Song ex­plained that China’s en­ergy con­sump­tion per unit of GDP is presently far more than that of the US and Ja­pan. There­fore, there is great po­ten­tial in re­duc­ing en­ergy con­sump­tion from the user side. He said, “We in­creased our pro­duc­tion ca­pac­ity by 20 times from 2010 to 2016, while the en­ergy con­sump­tion in­creased by only six times, as we have made a lot of ef­forts to save en­ergy. For ex­am­ple, af­ter we ap­plied new tech­nolo­gies in an old cen­tral air con­di­tioner in the orig­i­nal fac­tory, 1,000 kwh of elec­tric­ity was saved.”

Smart Mi­cro­grid

The tall wind­mill in BDA built by Xin­jiang Gold­wind Sci­ence & Tech­nol­ogy Co., Ltd. is ac­tu­ally a set of 2.5-megawatt (MW) per­ma­nent mag­net di­rect drive wind tur­bines. Gold­wind is one of the pi­o­neer en­ter­prises en­gag­ing in

wind tur­bine de­vel­op­ment and man­u­fac­tur­ing. Af­ter more than 10 years of de­vel­op­ment, it has be­come a lead­ing so­lu­tion provider for wind power. With high ef­fi­ciency, low main­te­nance and op­er­a­tion costs, ex­cel­lent grid con­nec­tion per­for­mance, and high avail­abil­ity, the com­pany’s 1.5- to 6.0-MW per­ma­nent mag­net di­rect drive wind tur­bines have been patented, and rep­re­sent the most promis­ing tech­ni­cal route in the field of global wind power.

By the end of 2016, the cu­mu­la­tive in­stalled ca­pac­ity of Gold­wind ex­ceeded 38 gi­gawatts (GW), and its cu­mu­la­tive an­nual en­ergy out­put reached 72 bil­lion kwh, equiv­a­lent to sav­ing 22.96 mil­lion tons of stan­dard coal, re­duc­ing 73.9 mil­lion tons of car­bon emis­sions, and cre­at­ing 40.38 mil­lion cu­bic me­tres of for­est. Ac­cord­ing to China Wind En­ergy As­so­ci­a­tion, Gold­wind ranks first for six con­sec­u­tive years na­tion­wide. Ac­cord­ing to the re­port of Bloomberg New En­ergy Fi­nance on global wind tur­bine man­u­fac­tur­ers’ mar­ket share, Gold­wind ranked third in the world in 2016.

Gold­wind be­gan ex­plor­ing smart mi­cro­grid, en­ergy In­ter­net and in­dus­tri­al­i­sa­tion as early as 2010. Cur­rently, its mi­cro­grid prod­ucts have been put into mass ap­pli­ca­tion, and have made break­throughs in the US and Thai­land mar­kets. By the end of 2016, the com­pany had built and op­er­ated over 10 mi­cro­grid projects all over the world, with ex­cel­lent per­for­mances in grid con­nec­tion and is­land­ing, pro­vid­ing eco­nomic, en­vi­ron­men­tally-friendly and con­ve­nient en­ergy so­lu­tions for lo­cal en­ter­prises and de­vel­op­ment zones.

Built in Au­gust 2010, the Smart En­ergy In­ter­net Pro­ject in the Re­new­able En­ergy Com­ple­men­ta­tion Park is the first in­verse power trans­mis­sion mi­cro­grid demon­stra­tion pro­ject in Bei­jing, the first mul­ti­ple en­ergy stor­age ap­pli­ca­tion and tech­nol­ogy plat­form in the world, the in­ter­na­tional IEC stan­dard test base, and the first Mw-level iso­lated is­land op­er­a­tion demon­stra­tion pro­ject with dis­trib­uted ac­cess of wind tur­bines.

In the Smart Mi­cro­grid Mon­i­tor­ing Room of Gold­wind in Bei­jing, the direc­tor said that the smart mi­cro­grid of Gold­wind Bei­jing Park con­tains about 1,250-kw pho­to­voltaic power gen­er­a­tion, 2,500-kw wind power gen­er­a­tion, com­bined cool­ing, heat­ing and power (CCHP) sys­tem com­posed of a 600kw mini gas tur­bine and two 65-kw mi­cro gas tur­bines, lithium bat­tery, vana­dium flow bat­tery, su­per ca­pac­i­tor and other en­ergy stor­age sys­tems. It pro­vides elec­tric­ity for Gold­wind of­fice build­ing, work­shop and big data cen­tre. A 2,000-kw wind tur­bine will be built in the smart mi­cro­grid in the fu­ture. The de­ploy­ment of this in­de­pen­dently-de­vel­oped en­ergy man­age­ment sys­tem will help build en­ergy In­ter­net sys­tems, in­crease the pro­por­tion of clean en­ergy in the park’s to­tal en­ergy con­sump­tion to 90 per­cent and more, and achieve flex­i­ble smart en­ergy con­trol over users. As a 1-MW sup­port­ing power pro­ject of the na­tional 863 ac­tive distri­bu­tion net­work, the pro­ject was named one of the “Cap­i­tal Blue Sky Ac­tion Tech­nol­ogy Demon­stra­tion Projects.”

Gold­wind’s smart mi­cro­grid pro­ject demon­strates well the many func­tions of smart mi­cro­grids. The eco­nomic ad­van­tages of smart mi­cro­grids can be sensed in the first com­mer­cial pro­ject of Gold­wind. Jiangsu Dafeng Wind Power In­dus­trial Park’s Smart Mi­cro­grid Pro­ject is the first com­mer­cial 1MW-

level grid con­nec­tion-type mi­cro­grid pro­ject na­tion­wide, in­clud­ing a 2-MW wind tur­bine, a 100-kw small wind tur­bine and a 96-kw pho­to­voltaic gen­er­a­tor, with the en­ergy stor­age device of 200 kw * 3 hours lead­car­bon bat­ter­ies, pro­vid­ing clean en­ergy for a num­ber of en­ter­prises.

A mon­i­tor­ing sys­tem al­lows real-time elec­tric­ity con­sump­tion in­for­ma­tion of the mi­cro­grid to be ob­tained. The gen­er­a­tion ca­pac­ity of this mi­cro­grid can sat­isfy 25 per­cent of the elec­tric­ity con­sump­tion of Jiangsu CRRC, achiev­ing self-use and sur­plus power trans­mis­sion to the grid. Build­ing smart mi­cro­grid for users can help them re­duce en­ergy costs, and pro­vide an­cil­lary ser­vices, such as im­prov­ing the power sup­ply in parks.

In 2016, Gold­wind car­ried out a dozen smart mi­cro­grid projects at the same time, con­tin­ued to ex­plore more busi­ness mod­els and ap­pli­ca­tion tech­nolo­gies—in­clud­ing a mi­cro- com­bus­tion en­gine CCHP sys­tem in parks—pro­vided cool­ing and heat­ing ser­vices for parks, and con­tin­ued to ex­plore the var­i­ous ap­pli­ca­tions for their en­ergy ef­fi­ciency plat­form. Data col­lec­tion and re­duc­tion pro­vides data sup­port for the best ca­pac­ity de­sign of mi­cro­grid. Backed by its ad­vanced tech­nolo­gies and ex­pe­ri­ence in the field of smart en­ergy, Gold­wind suc­ceeds in pro­vid­ing so­lu­tions for the Smart City Pro­ject of Dafeng Dis­trict, Yancheng City, Jiangsu Prov­ince, and the com­pre­hen­sive en­ergy ef­fi­ciency projects of sev­eral do­mes­tic man­u­fac­tur­ing en­ter­prises. Stick­ing to the cor­po­rate mis­sion of “con­tribut­ing to a good ecol­ogy while sav­ing more re­sources for the fu­ture,” Gold­wind has al­ways played an ac­tive role in ex­plor­ing the fields of en­ergy sav­ing, en­vi­ron­men­tal pro­tec­tion, new ma­te­rial and green tech­nol­ogy, striv­ing to be­come a world-lead­ing over­all so­lu­tion provider of clean en­ergy, en­ergy sav­ing and en­vi­ron­men­tal pro­tec­tion.

New Agri­cul­ture

At a smart pho­to­voltaic green­house, a staff mem­ber of Gold­wind Tech­nol­ogy said, “China's agri­cul­ture is un­der­go­ing a third in­dus­trial trans­for­ma­tion. Through the in-depth study of the sta­tus and fu­ture de­vel­op­ment of mod­ern agri­cul­ture, we be­lieve that re­fined smart agri­cul­ture will pre­vail. How­ever, be­cause of the long pay­back pe­riod of agri­cul­tural in­vest­ment, agri­cul­ture is now con­strained by a low in­tel­li­gence level and high en­ergy sup­ply cost. To achieve the sus­tain­able de­vel­op­ment of an agri­cul­tural econ­omy, we com­bine new en­ergy and agri­cul­ture to de­velop an eco-econ­omy fea­tur­ing ‘new en­ergy plus smart agri­cul­ture,' and make new en­ergy in­come the pre-cap­i­tal guar­an­tee of the agri­cul­tural in­dus­try. The area of our ex­per­i­men­tal green­house is about 0.27 hectares. Cur­rently, an­other new en­ergy and agri­cul­ture demon­stra­tion park is built in Zhangji­akou City, He­bei Prov­ince to trans­form part of our re­search re­sults.”

There are toma­toes and leafy veg­eta­bles of dif­fer­ent va­ri­eties in the green­house. The tomato plant­ing area adopts an eco-friendly ma­trix and a water and fer­tiliser in­te­gra­tion sys­tem, which makes it pos­si­ble to fer­tilise plants ac­cord­ing to their va­ri­eties, growth pe­ri­ods and in­di­vid­ual needs. Or­ange-red pho­to­voltaic pan­els are in­stalled on the roof of the green­house, with a light trans­mit­tance of 19 per­cent. The pan­els are ar­ranged ac­cord­ing to the light re­quire­ment of the plants. There­fore, a small smart mi­cro­grid has taken shape in the green­house. The pho­to­voltaic elec­tric­ity is supplied for the green­house to use, while the sur­plus elec­tric­ity is trans­mit­ted to the mi­cro­grid. At night or in the win­ter when the amount of pho­to­voltaic elec­tric­ity gen­er­a­tion is not enough, the green­house can “take back” the pho­to­voltaic elec­tric­ity from the smart mi­cro­grid. In Bei­jing, pho­to­voltaic elec­tric­ity gen­er­a­tion can meet the green­house's de­mands for elec­tric­ity from March to Oc­to­ber.

At this stage of chang­ing from tra­di­tional agri­cul­ture to mod­ern agri­cul­ture, China closely com­bines its agri­cul­ture, mod­ern in­dus­try, emerg­ing tech­nol­ogy and in­for­ma­tion, and new en­ergy. Green and low­car­bon wind power and pho­to­voltaic power achieve har­mony be­tween na­ture and hu­man be­ings, with­out the risk of re­source de­ple­tion. Com­pared with coal, oil and nat­u­ral gas, wind and so­lar en­ergy is in­ex­haustible. Many new en­ergy en­ter­prises try to ex­plore new mod­els for com­bin­ing new en­ergy and agri­cul­ture, to pro­mote plants growth and meet their own de­mands for en­ergy.

BOE is also ex­plor­ing a com­bi­na­tion of new en­ergy and agri­cul­ture. Song Hang­bin said, “In the past, it took 30 days to grow seedlings in the soil, and then the seedlings would be trans­ferred to nat­u­ral light for cul­ti­va­tion. We've now put for­ward the con­cept of a plant fac­tory where it just takes seven days to grow seedlings, and 30 days to make them ripe by suit­able LED light­ing.” He con­tin­ued to say, “The orig­i­nal green­house could grow four ro­ta­tions of veg­eta­bles per year, but now the plant fac­tory can grow 10 to 12 ro­ta­tions of veg­eta­bles per year. When this new plant­ing tech­nol­ogy is ma­ture, the pro­duc­tion ca­pac­ity will in­crease, and so will the har­vest of unit area. Our plant fac­tory is lo­cated in Dax­ing Dis­trict with an area of 4,500 square me­tres. It can achieve year-round pro­duc­tion, and pro­duce 80,000 veg­eta­bles monthly, five times more than that of tra­di­tional land. Presently, veg­eta­bles pro­duced by the plant fac­tory have been pro­vided to sev­eral restau­rants in Bei­jing.”
