  • 实现碳中和、绿电成为主要电力来源,这一目标距离我们似乎还比较遥远,至少还有二三十年时间吧。

    然而,看似遥远的场景在昨天却出现了。9月20日,澳大利亚主电网创造出一个纪录:在半小时内,可再生能源发电占到70%以上。虽然只有半小时,这却为我们展示了一个绿色的未来。

    今天,澳大利亚能源市场运营商(AEMO)向欧洲能源门户证实,本周三(9月20日),该国主要电网的可再生能源占比,创下历史新高。

    根据AEMO数据,9月20日上午11点至11点30期间,澳洲的可再生能源并网比例,高达惊人的69.9%。与此同时,发布全国电力市场数据的在线平台OpenNEM在9月20日上午11点45分,更是创下70.6%的最高峰值。以上两个数字,均创下澳大利亚家电力市场(NEM)可再生能源电力的历史新高。

    在上述绿电的闪光时刻,澳洲的屋顶太阳能发电占到那可再生能源比例的38%,其次是集中式电站,占比为17%、风力发电占比13%,以及水力发电占比2%,为家庭和企业提供的电力总计,超过19吉瓦。

    据AEMO称,上述可再生能源的创纪录高点,同时导致了该国煤炭发电量创下历史新低。9月20日上午11:45,该公司记录的NEM煤炭瞬时最低份额,仅为28.5%。

    以上还不是一种最极端的统计。在当时,其实有约12.6%(4吉瓦)的可再生能源已经被削减,考虑这一因素,可再生能源电力的渗透率将会更高。

    根据咨询公司Energy Edge董事总经理斯特布勒(Josh Stabler)统计,如果这些多余的可再生能源得到利用,可再生能源在澳大利亚家电力市场的渗透率,将会达到惊人的83.2%。

    斯特布勒同时指出,该时段绿电严重产能过剩,很大一部分是由于维多利亚州、昆士兰州和南澳大利亚州的大幅负电价造成的。

    为了避免弃风弃光,斯特布勒建议,应该尽快建设新型储能,包括大力推动电气化、电动汽车、绿氢生产等。目前,澳大利亚年平均可再生能源渗透率,已经来到37.5%。

    当然,尽管取得了上述成就,但可再生能源的更高渗透率,仍有尚未开发的巨大潜力,可以通过部署额外的电池存储和整合新兴技术来释放这一潜力。这些进步对于实现澳大利亚的可再生能源目标至关重要。

    • 国际能源署(IEA)数据显示,2021年,全球太阳能、风能和其他可再生能源发电的新增产能已创下纪录。为了保障能源安全,改善气候环境,各国政府可再生能源利用水平不断提高,并且今年将进一步提升。 国际能源署(IEA)发布《可再生能源市场更新》指出,2021年,全球新增可再生能源发电克服了供应链危机,施工延误和原材料价格高等问题,发电量高达295吉瓦,创下历史新高。预计2022年,全球新增发电量将达到320吉瓦,相当于欧盟的天然气发电总量,几乎能够满足德国全部电力需求。太阳能光伏发电量有望在2022年达到全球可再生能源新增发电量的60%,排名第二和第三的分别是风力发电和水力发电。 今明两年新增光伏发电量有望破纪录 报告显示,2021年,欧盟的可再生能源发电新增装机量猛增近30%,达到36吉瓦,超过了欧盟在十年前创下的35吉瓦的纪录。2022年和2023年投入使用的可再生能源新产能有可能显著降低欧盟电力部门对俄罗斯天然气的依赖。 报告指出,今年以来,得益于中国、欧盟和拉丁美洲强有力政策的支持,可再生能源的增长速度远快于最初的预期。而美国的前景因风能和太阳能新激励措施的不确定性以及针对太阳能进口的贸易行动而黯淡。 报告指出,今明两年,全球新增太阳能光伏发电量有望打破纪录,到2023年,年发电量将达到200吉瓦。中国和印度的大规模太阳能项目均有政策支持,所以两国的太阳能项目发展速度变快,并且项目成本比使用化石燃料的替代品更低。在欧盟地区,由于电费上涨,家庭和公司安装太阳能屋顶装置还能帮消费者节省开支。 报告还明确提出警示:如果各国没有更强有力的政策,随着太阳能将继续推进,可再生能源的增加量将在2023年趋于平稳,但水电的增加量将下降40%,而风电的增加量将相对保持不变。 “最近几个月的能源市场发展——尤其是在欧洲,再次证明了可再生能源在改善能源安全方面的重要作用,此外它们在减少排放方面已经确立了有效性。”国际能源署署长法提赫·比罗尔希望各国政府削减“繁文缛节”,加快审批进程,并为更快部署可再生能源提供适当的激励措施。 可再生能源成本增加但竞争力没有削减 报告显示,自2021年初以来,许多原材料价格和运费成本一直呈上涨趋势。到2022年3月,太阳能级多晶硅价格翻了4倍多,钢材价格上涨了50%,铜上涨了70%,铝上涨了一倍,运费上涨了近5倍。十年来光伏发电、风电成本持续下降的势头首次出现逆转,这是由于风机和光伏组件的价格上涨,制造商向下游转嫁设备成本的涨幅。 报告明确指出,各国政策具有不确定性,许可条例冗长复杂,都阻碍了风电行业的发展。2020年太阳能装机容量达到惊人水平,2021年却骤降了32%,预计今明两年新增陆上风力发电量将出现恢复性增长。 在全球范围内,自去年以来,许多地区的电力价格都突破了历史纪录,尤其是那些以天然气作为电力批发市场最终分时电价和每日电价“定价之锚”的国家。这在欧盟国家尤为普遍,与2016年至2020年的均值相比,德国、法国、意大利和西班牙如今的批发电价平均上涨了6倍以上。 报告显示,从历史上看,光伏发电和风电拍卖的长期合同价格一直高于许多大型欧盟市场的批发电价。然而,即便是过去五年签署的价格最高的陆上风电和公用事业规模光伏发电合同,只有今天欧盟平均批发电价的一半。 清洁能源转型紧迫性加快 俄乌冲突增加了清洁能源转型的紧迫性,部署更多可再生能源现已成为许多国家的战略要务,尤其是欧盟。 欧盟国家对俄罗斯天然气的依赖程度不同。在欧盟成员国中,就绝对发电量而言,德国和意大利对俄罗斯天然气的依存度最高。然而,根据报告对2023年风电和光伏发电的市场预期,德国以可再生能源减少对俄气依赖的潜力明显高于意大利——除非后者出台新的、更强有力的政策并且加快实施步伐。法国和荷兰对俄罗斯天然气的依赖度相对较低,这使得可再生能源取代天然气的潜力更大。相反,在奥地利、匈牙利和希腊,可再生能源扩张对于减少对俄罗斯天然气依赖的作用依然有限。 报告称,今年和明年,全球新增光伏发电装机量有望创下新纪录,到2023年全年新增将达到200吉瓦。光伏发电在中国和印度市场的增长正在加速,这得益于对大型项目的强有力政策支持,可以比化石燃料替代品实现更低的成本。在欧盟,随着电费上涨,家庭和公司安装屋顶太阳能有望帮助消费者省钱。 由于中国多个省份推出的激励措施和欧盟市场的扩张,2022年全球海上风电装机容量将比2020年增加一倍。预计中国将在2022年底超过欧洲,成为全球最大的海上风电市场。

    • Renewable Energy Gains in Australia . February 25, 2024February 24, 2024 16 hours ago David Waterworth 0 Comments Sign up for daily news updates from CleanTechnica on email. Or follow us on Google News ! It is a sweltering Queensland summer. The air conditioner is belting out cold dry air as we hit a maximum of 35 degrees Celsius in Brisbane with very high humidity. Down south in the “colder” states (Victoria) they are achieving maximums of over 40 degrees, whereas in the west, records are tumbling as some areas head towards 50 degrees. Three tornadoes in the north of Australia have kept Queensland humidity high, and the vegetation lush — though, there has been a lot damage from winds and flooding. The humidity is keeping bushfires at bay in the north, but Victoria is burning with loss of property, wildlife, and stock. Some anti-wind farm lunatics are actually saying that the local wind farms are fanning the flames and making the fires worse! These extreme climate events are becoming more and more severe, and more frequent. The weather has become the news. But some still doubt that there is such a thing as climate change and fight the forward march of renewable energy . Some good news, though! The federal government has declared three offshore wind zones off the coast of New South Wales, Victoria, and Western Australia — it is strange that there are as yet no zones designated for South Australia and Queensland. Three more are being considered. The mythbusting page from the Department of Climate Change, Energy, the Environment and Water deals deftly with the FUD being thrown at the industry — offshore wind farms will not be visible from the beach; there won’t be any cables running along the beach (for the surfers to get tangled in); offshore wind turbines are not as big as the Eiffel Tower; offshore wind farms won’t scare away the tourists. Yes, they have lights, but they are for safety reasons. Yes, these are real objections — promoted by conservative politicians and media, and, sadly, believed by many. But wait, there’s more: Wind turbines save more carbon than is emitted during their manufacture; you can’t hear them turning from the beach; offshore wind farms won’t make the beach hotter; they will have measures in place to protect whales and sea birds; you can still fish! A few days ago, the federal government commenced the consultation process for a wind energy development zone off the coast of southern Western Australia. The area can accommodate up to 20 GW of projects powered by wind from the Indian Ocean. It will be situated at least 20 km off the shore — so it won’t ruin the view! Offshore wind projects take time. Federal energy minister Chris Bowen cautions us: “We are at the very beginning of a multi-year process . More studies and consultation will happen before offshore wind projects can be given the green light.” According to Norton, Rose, Fullbright , Australia has the potential to harvest 2,000 GW of power from offshore wind. Now, that’s energy security! Onshore wind continues to progress, with records being continuously broken for the largest wind farm. Recently, it was Macintyre in Queensland, then Golden Plains in Victoria — now it is the 1500 MW Yanco Delta wind farm in New South Wales. Yanco has just been approved by Australia Minister for the Environment and Water Tanya Plibersek and is situated in a declared Renewable Energy Zone. Yanco will consist of 208 wind turbines, which will each have a tip height of 270 metres. They will be connected to an 800MW/800MWh battery. There continues to be progress in the installation of large-scale batteries, large- and small-scale solar, and of course rooftop renewable energy for the common man and woman. One that came to my notice is the installation of a 250 MW/500 MWh battery at a former power station at a coal mine in Ipswich, Queensland. How ironic. This site has quite the history — it is situated on a coal mine which dates back over 100 years. Not all the tunnels have been mapped and recorded (a close suburb is suffering subsidence due to tunnels collapsing). Until recently, the tunnels had been used to deposit rubbish from nearby New South Wales, and some areas are burning slowly. Let’s hope the engineers do a good job. For once, I am agreeing with some of the local naysayers on their Facebook page. The Tesla battery will arrive later this year and the site should be operational by mid 2025, supplying power for the two-hour evening peak and reducing reliance on high-priced gas generation. The politicians, locals, and I all hope that this leads to reduced power bills. “Renewables are driving down the spot wholesale price of power below zero, which is why we will continue to invest in them,” says Queensland Premier Steven Miles. The state is also investing over half a billion dollars to stimulate a homegrown battery industry. In the “Nero fiddles while Rome burns department,” we have the farcical debate in federal parliament over a bill from an independent senator which seeks to protect children and future generations from the effects of climate change. Both Labour and Liberal politicians questioned whether climate change presented a pressing a health risk at all. Do these people not look out the window, or watch the news? Are they blinded by their own pecuniary interest. No and yes, methinks. At the federal level, just to muddy the water further, the conservative federal opposition is proposing that rooftop solar should be boosted with more subsidies. Isn’t that, you say, a good thing? Sounds like it, but they are planning to get the money by stopping government support for solar and wind farms. Perhaps that would convince my neighbour to put solar on his roof. It is one of the very few in my neighbourhood that has none — he says it is too expensive to install! As I sit at my computer looking out the window, it is a grey and overcast day in Brisbane. So, I thought I would check how the country is doing with renewable energy power generation today. For those who like the numbers: Queensland is generating 1.5 GW of power from wind and solar and 5.5 GW from coal. NSW is generating 4.4 GW from renewables and 5.6 GW from fossil fuels. For Victoria, the numbers are: 1.8 GW and 2.5 GW (brown coal). For South Australia, they are 1.5 GW and 0.7 GW (gas). For Western Australia, they are 225 MW wind and solar, 2 GW coal and gas. As usual, Tasmania is the star of the show with 100% hydropower, wind, and solar. It is impossible to write up all the news that is happening in the renewable energy sector in Australia. These are just some snippets that have interested me. Suffice to say, progress is being made on all fronts, as is evidenced by a look at the live NEM widget . This is despite the crazy (literally, sometimes) attempts to keep coal, oil, and gas in the loop. Have a tip for CleanTechnica? Want to advertise?
