脱碳——工业的制胜之牌
工业供热脱碳现在在布鲁塞尔得到了更多的关注。10月11日，国会议员比阿特丽斯·科瓦西（Beatrice Covassi）与Solar Heat Europe在欧盟议会组织了一场题为“实现工业脱碳”的活动。法国南部麦芽生产商 Boortmalt 的10MW太阳能工业热厂是两小时活动中展示的两个案例研究之一，活动以社交饮料结束。法国New Heat总裁Hugues Defreville和比利时Boortmalt集团能源优化经理Gianni Vanneste（左三和左四）以及Solar Heat Europe的Pedro Dias（右一）在约90名与会者参加的小组讨论中解释了太阳能工业供热的重要性。

“这次活动向我们发出了来自欧洲议会和欧盟委员会的明确政治信号，即到目前为止，高温议程被低估了，需要获得更多的知名度，”Solar Heat Europe董事总经理Valérie Séjourné说。“随着明年新的委员会和议会的成立，这将需要为2040年的目标而努力，我们的技术将在欧盟和地方层面获得进一步的动力、推广和支持。
Boortmalt是绿色工业供热解决方案的合适案例研究。这家比利时集团在全球经营着27家麦芽厂，并制定了影响深远的气候目标。自2021年以来，它一直是科学基础目标倡议的成员，并承诺到2030年实现50%的脱碳。这一目标已经在法国伊苏丹的工厂实现。在那里，室外空气首先通过麦芽干燥过程的废热和燃气锅炉的废气预热至40°C左右，以干燥谷物以生产麦芽。然后，空气被太阳能罐加热到所需的 67°C。在夜间和低辐照期间，空气加热的备用能源部分来自生物质锅炉。
工业供热脱碳——房间里的大象
“我很高兴房间里的大象——工业供热脱碳——终于在欧洲层面上得到了解决，”范内斯特在演讲中说。Boortmalt 将自己的1.5 °C目标建立在四大支柱之上：太阳能热能、地热能、供热电气化和区域供热。
“我们始终选择最具成本效益的脱碳技术。当太阳能从这个分析中出来时，这是因为良好的辐照区域和廉价的可用土地的高产量。Boortmalt正在考虑的可能的太阳能站点主要位于西班牙和澳大利亚。其中一个太阳能脱碳项目是西班牙的工程阶段，其储热量相当于80个奥林匹克游泳池，因此太阳能部分可以满足工厂90%的热量需求。

比利时安特卫普港附近的Boortmalt工厂的脱碳将基于与热回路的连接。一个12公里长的热管系统正在建设中，它将把废热从焚烧厂带到温度为100°C的麦芽厂。废热将使Boortmalt工厂的气体消耗量减少一半。计划于今年年底开始运营。
2023年10月11日，Solar Heat Europe 团队和支持欧盟议会活动的 SHE 成员之间露出了非常高兴的面孔。该活动的计划早在2022年秋季就开始了，当时投资行业协会接到了电话。Solar Heat Europe与欧洲地热能委员会联合申请提交一份展示旗舰项目的提案，该提案于今年3月初获得批准。

该活动向欧洲机构发出了一个明确的信息，即太阳能热能已准备好通过对欧洲制造基地的大力投资来扩大规模。“我们不想将能源转型分包给中国，因此我们需要在碳定价、降低化石燃料补贴以及为工业和区域供热参与者制定具有约束力的可再生能源目标方面提供更多支持”，Solar Heat Europe总裁Guglielmo Cioni在闭幕词中明确表示。
Cioni还感谢主办此次活动的欧洲议会议员兼可持续，长期投资和竞争性欧洲工业集团联合主席Beatrice Covassi。她强调，欧洲工业应将可持续发展作为制胜之牌。编译 陈讲运
Decarbonization – a winning card for industry
Decarbonization of heat in industry is now getting a lot more attention in Brussels. The Member of Parliament Beatrice Covassi together with Solar Heat Europe organized an event at the EU Parliament on 11 October under the title “Enabling industrial decarbonization”. The 10 MW solar industrial heat plant at malt producer Boortmalt in Southern France was one of two case studies presented during the two-hour event, which ended with networking drinks. Hugues Defreville, President of New Heat in France, and Gianni Vanneste, Group Energy Optimization Manager at Boortmalt in Belgium (third and fourth from left) together with Pedro Dias from Solar Heat Europe (first on the right) explained the importance of solar industrial heat during the panel discussion attended by around 90 participants.

“This event has given us clear political signals from both the European Parliament and the European Commission that the heat agenda has been underestimated so far and needs to gain more visibility”, said Valérie Séjourné, Managing Director of Solar Heat Europe. “With a new Commission and Parliament coming up next year, which will need to work on the 2040 targets, our technology will gain further momentum, promotion and support, both at EU and local levels.”
Boortmalt is a suitable case study for green industrial heat solutions. The Belgian group operates 27 malt houses around the world and has far-reaching climate goals. It has been a member of the Science Base Target Initiative since 2021 and has committed itself to 50 % decarbonization by 2030. This goal has already been achieved at the factory in Issoudun, France. There, the outside air is first preheated by waste heat from the malt drying process and the exhaust fumes of the gas boilers to around 40 °C to dry the grains to produce malt. The air is then heated by the solar tank to the required 67°C. During the night and low-irradiation periods, backup energy for air heating comes partly from a biomass boiler.
Decarbonizing of heat in industry – the elephant in the room
“I am pleased that the elephant in the room – decarbonizing industrial heat – is finally being addressed on a European Level,” said Vanneste during his presentation. Boortmalt is basing its own 1.5 °C target on four pillars: solar thermal, geothermal, electrification of heat and district heating.
“We always opt for the most cost efficient decarbonization technology. When solar comes out of this analysis it is because of the high yields in good irradiation areas and cheap available land.” Possible solar sites that Boortmalt is looking at are mostly in Spain and Australia. One of the solar decarbonization projects is the engineering phase in Spain with a heat storage volume equivalent to 80 Olympic swimming pools, so that a solar fraction of 90 % of the factory’s heat demand is reached.

The decarbonization of the Boortmalt factory near the port of Antwerp in Belgium will be based on connection to a heat loop. A 12 km heat-pipe system is under construction, which will bring waste heat from an incineration plant to the malting factory at temperatures of 100 °C. The waste heat will reduce the gas consumption of the Boortmalt factory by half. Operation start is planned for the end of this year.
Very happy faces among the Solar Heat Europe team and the SHE members who supported the EU Parliament event on 11 October 2023. Planning for the event began already in autumn 2022 with a call from the Investment Industry Intergroup. Solar Heat Europe applied jointly with the European Geothermal Energy Council to submit a proposal showcasing flagship projects, which was approved in early March this year.

The event has sent a clear message to the European institutions that solar thermal is ready to scale up with strong investments into the European manufacturing base. “We do not want to subcontract the energy transition to China, so we need more support in terms of carbon pricing, lower subsidies on fossil fuels and binding renewable targets for industry and district heating players”, Guglielmo Cioni, President of Solar Heat Europe, made clear in his closing remarks.
Cioni also thanked Beatrice Covassi, Member of the European Parliament and Co-Chair of the Sustainable, Long-term Investments & Competitive European Industry Intergroup who hosted the event. She underlined that European industry should make sustainability its winning card.
