德国柏林阿德勒斯霍夫地区的地球研究中心的科学家正在评估一个拟议的含水层热储项目的地下情况。迄今为止，已经进行了450米的试钻，进入了适合储水的砂岩层。

这个热储项目将与位于舍内魏德地区的区域供热公司BTB运行的热泵设施相辅相成。热泵从斯普雷河中取水，提取热能并将其输送到柏林区域供热网络中。然而，该系统在夏季产生过多的能量，在冬季产生过少的能量。

如果成功，含水层热储可以在夏季储存多余的能量，并在冬季提供。水被保持在数百米地下的温暖，但是这样的系统需要特定类型的岩石才能运行。

“[它们]是实施能源转型的关键。以使系统能够稳定运行，”来自波茨坦GFZ的SvenFuchs博士评论道。

阿德勒斯霍夫的热储设施完成还需要几年时间。在此期间，其容量也将受到限制-它可以储存足够的能量供应约3000户家庭一个冬季季节。为了扩大这个容量，BTB的董事总经理DavidWeiblein表示，需要在柏林进行几次勘探钻探活动。这带来了失败的风险，因此需要柏林州以资金或其他财务激励形式的支持。

当阿德勒斯霍夫的含水层热储设施完成时，它将成为柏林最大的同类项目。目前，联邦议院下方有一个地方地热能储存设施。

BTB的项目经理StephanieDedeyne希望该项目能够获得更快的批准和更少的官僚主义。根据Stephanie的说法，该设施的开发仍需要至少四年的时间，尽管她期待其完成和启动，但实现这一目标的过程将“可能是一条崎岖的道路。”

之前已经宣布在柏林进行大规模地热区域供热计划，最初有三个勘探钻探点。该计划已经扩大，增加了九个额外的勘探钻孔和一项三维地震勘测，覆盖整个城市区域。

Scientistsfrom the Georesearch Center in Potsdam is evaluating the subsurface in the locality of Adlershof in Berlin, Germany for a proposed aquifer thermal storage project. Test drilling has so far been done to a depth of 450 meters, accessing sandstone suitable for water storage.

Thethermal storage project will complement a heat pump facility being run by district heating provide BTBin the area of Schöneweide. The heat pumps draw water from the Spree river, extracting the heat and feeding it into the Berlin district heating network. However, the system generates too much energy in the summer and too little in the winter.

Ifsuccessful, aquifer thermal storage can store the excess energy during summer and make it available during winter. The water is kept warm at hundreds of meters underground, although certain types of rock are needed for such a system to work.

“[They]are essential in order to be able to implement the heat transition. So that the system can function stably,”commented Dr Sven Fuchs from GFZ Potsdam.

Itwill still take a few years before the thermal storage facility in Adlershof is finished. Its capacity will also be limited for the meantime – it can storage enough energy to supply around 3000 households over a winter season. To expand this capacity, BTB Managing Director David Weiblein said that several exploratory drilling campaigns will be needed across Berlin. This carries the risk of failure, so support from the state of Berlin in the form of funding or other financial incentives will be necessary.

Whenthe Adlershof aquifer thermal storage facility is completed, it will be the largest project of its kind in Berlin. Currently, there is a local geothermal energy storage facility under the Bundestag.

StephanieDedeyne, Project Manager at BTB, is hoping for faster approvals and less bureaucracy for the project. According to Stephanie, it will still take at least four years for the facility to be developed, and although she looks forward to its completion and launching, the process of getting there will “probablybe a rocky road.”

Plansfor large-scale geothermal district heatinghad previously been announced in Berlin, initially with three exploratory drilling sites. The plan hassince been expandedwith nine additional exploratory boreholes and a 3D seismic survey to cover the entire city area.
