Increasing reliance on intermittent renewable electricity sources makes balancing supply to demand difficult. This will become increasingly challenging as the proportion of renewables increases into the future. One solution is the large-scale geological storage of energy in the form of hydrogen. Electricity generation from stored hydrogen can balance summer to winter seasonal energy demands, with the added potential for hydrogen to repurpose the gas grid and replace methane for heating. This is significant as the heating of buildings is currently the largest source of carbon emissions in the UK, exceeding those for electricity generation.However, the underground storage of hydrogen in porous rocks has not yet been demonstrated commercially. This project hence uses state-of-the-art laboratory experiments to address questions which require insight before commercial trials occur, focusing on the geological (underground) storage of hydrogen in geographically-widespread porous rocks. Storage of hydrogen underground is well established in caverns of halite (salt). However, in the UK this type of geology is restricted only to Teesside, Northern Ireland and Cheshire, with long and costly transport to consumers elsewhere. Methane gas in the UK is already stored underground onshore in porous reservoirs and offshore in re-purposed natural gas fields, and that provides insight to operational designs and challenges. The project partners have expertise in hydrocarbon reservoirs, geological assessment of CO2 storage, and compressed air energy storage using porous rocks.WP1 Hydrogen reactivity examines whether the hydrogen could react chemically with the rocks into which it is injected or the overlying seal rock, which could prevent the gas from being recovered and used. Controlled laboratory experiments with hydrogen injection into porous rock at subsurface temperatures and pressures will identify and quantify likely chemical reactions.WP2 Petrophysics assesses how effectively hydrogen migrates through water-filled porous media, and how much of the injected hydrogen can actually be recovered from the rock. Because the rock is made of solid grains with a network of pore spaces between, capillary forces naturally trap some of the hydrogen. How much is trapped affects the commercial viability of the whole process. Laboratory-based experimentation will inject hydrogen into rock samples to help answer this question. CT scanning provides live 3D images of the hydrogen retention in the rock pores.WP3 Flow simulation uses digital computer models of fluid flow adapted from hydrocarbon simulation to scale up from laboratory experiments to an underground storage site. Hydrogen reactive flow properties from WP1 and WP2 will be used to calibrate numerical fluid flow software codes. These models can calculate how efficiently the hydrogen can be injected, and predict how much of the hydrogen can be recovered during operation. Volumes and types of cushion gas to be left in the reservoir as a precaution to maintain operation pressure and minimise water encroachment during withdrawal periods will also be assessed.WP4 Public perception considers how societal familiarity with hydrogen may be much lower compared to natural gas. A key objective of the project is to ascertain at an early stage how citizens and key opinion shapers feel about hydrogen storage underground, and to engage civil society with the research and development process to ensure that hydrogen storage develops in a way that is both technically feasible and socially acceptable.WP5 Project management, industry advisory board, communication and outreach are essential in this type of project. Digital updates will be posted on a dedicated project website and social media channels, with presentations made at academic and industry events. Public project reports and, eventually, peer reviewed publications will provide an open access record of project progress.

对间歇性可再生电力源的依赖越来越依赖，使需求的供应变得平衡。随着可再生能源的比例增加，这将变得越来越具有挑战性。一种解决方案是以氢的形式大规模的能量储存。从储存的氢中发电可以平衡夏季到冬季季节性能量的需求，并增加氢气再利用气电网并取代甲烷进行加热的潜力。这很重要，因为建筑物的加热目前是英国最大的碳排放来源，超过了发电的碳排放。因此，该项目使用最先进的实验室实验来解决需要在商业试验之前进行洞察力的问题，重点是地质（地下）在地理广泛的多孔岩石中储存氢。地下氢的储存已在Halite（盐）的洞穴中得到很好的确定。但是，在英国，这种类型的地质仅限于北爱尔兰和柴郡的Teesside，又有昂贵且昂贵的消费者运输。英国的甲烷天然气已经在陆上的地下存储在多孔的水库和近海中，并在重新塑造的天然气田中存储，这为操作设计和挑战提供了见识。该项目合作伙伴在碳氢化合物储层，二氧化碳存储的地质评估以及使用多孔岩石的压缩空气存储方面具有专业知识。WP1氢反应性检查氢可以与注入的岩石或上覆盖的密封岩相化地反应，从而防止气体被回收和使用。在地下温度和压力下将氢注射到多孔岩石中的受控实验室实验将识别和量化可能的化学反应。WP2石油物理学评估了如何有效地通过水填充的多孔培养基迁移氢，并且实际上可以从岩石中回收多少注射的氢。由于岩石是由固体晶粒制成的，毛细管之间具有孔隙空间的网络，因此毛细管自然会捕获一些氢。被困的多少会影响整个过程的商业生存能力。基于实验室的实验将把氢注入岩石样品中，以帮助回答这个问题。 CT扫描提供了岩石孔中氢保留的实时3D图像。Wp3Flow Simulation使用从碳氢化合物模拟适应的流体流量的数字计算机模型，从实验室实验到地下存储站点进行扩展。 WP1和WP2的氢反应流量特性将用于校准数值流体流量软件代码。这些模型可以计算如何有效地注入氢，并预测在运行过程中可以回收多少氢。还将评估储层中要保留的垫子气体的体积和类型，以预防措施，以维持运行压力并最大程度地减少戒断期间的水分侵占。WP4公众认识考虑到与天然气相比，对社会熟悉的氢气可能如何低得多。该项目的一个关键目的是在早期阶段确定公民和关键意见塑造者对氢存储地下的感觉，并吸引民间社会进行研发过程，以确保以技术上可行且在公路上可接受的方式发展氢气。WP5项目管理，行业咨询委员会，沟通，沟通和推广至关重要。数字更新将发布在专门的项目网站和社交媒体渠道上，并在学术和行业活动中进行了演讲。公共项目报告，最终，同行评审的出版物将提供项目进度的开放访问记录。
