With Canada’s carbon tax set to rise to C$170 per ton by 2030 from C$40 per ton now, oil and gas firms operating in Alberta's key energy hub are responding to a provincial government request for proposals to build new or larger underground carbon capture and storage projects.

Alberta’s push to create a massive carbon capture grid comes as Canada scrambles to slash greenhouse gas emissions 40-45% by 2030. A federal investment tax credit for carbon capture projects is anticipated..

省能源官员现在正在评估48 different plans, aiming to invite a subset to submit final proposals in December, said Jerry Bellikka, Alberta energy ministry chief of state, in an email. The province said it seeks to create carbon capture hubs that will “provide open access to all emitters,” and not limited to carbon emissions of particular proponents and companies

Terming submissions confidential, the province declined to disclose proposer identities, but they "probably represent most of the major players in the region and some of the ambitious junior players,” says Mark Lea-Wilson, hydrogen hub lead at The Transition Accelerator, a Canadian non-profit business advisor on net-zero and climate change approaches.

碳存储方法

Pembina Pipeline Corp. in June announced a joint proposal with TC Energy to lease underground space from the province to build a large carbon capture and storage hub.

Pembina提议对其现有管道网络的一部分进行改造，将碳捕获到艾伯塔省水库的萨斯喀彻温省，它说足够大，可以容纳20亿吨₂，代表“数十年的隔离能力”。

荷兰皇家壳牌公司还在7月份宣布了一项计划，旨在从埃德蒙顿附近的炼油厂和化学厂中捕获和存储多达3亿吨的碳，该碳在其CCS项目的一生中。在其第一阶段，它将每年捕获和存储多达750,000吨碳。

壳牌表示，它将在2023年对该设施做出最终的投资决定，IT和Pembina都将于2025年启动其各自项目的初始阶段。18luck官网

Shell and U.S. independent power producer Silicon Ranch, in which the oil company holds an ownership stake, also plan to develop a $100-million solar project on a 414-acre site to provide up to 20% of the facility’s power when it operates in 2023, according to published reports.

Meanwhile, Pembina CEO Mike Dilger has approached executives linked to rival proposals about combining forces on a single carbon capture and storage project. "A single, large carbon capture program at scale is by far the most sensible way to do things," he told Reuters, terming such an approach "a more cost-effective solution."

建立协同作用？

过渡加速器的Lea-Wilson在此类链接中指出了基本协同作用。

彭比纳（Pembina）可以利用其管道从壳牌的炼油厂和油砂途径成员的石油设施中汇入碳，该集团由加拿大能源生产者，加拿大天然，塞诺维斯能源，加拿大康菲氏菌，帝国，梅格能源和阳光能量组成。

莱维尔森说：“壳牌的北极星项目利用彭比纳提供的基础设施是有道理的。”

多伦多律师事务所的合伙人桑德·邓肯森（Sander Duncanson）说与能源部门客户合作的Osler，Hoskin＆Harcourt LLP。

Profit margins are thin, and paying another operator, such as a pipeline operator, to funnel carbon to an underground storage hub would be an added expense, he says.

For some oil and gas operators, it may make more sense to store carbon on site, although that isn’t possible for companies working in Alberta's oil sands region, where geological conditions preclude building underground carbon storage complexes, Duncanson says.

“There is a lot of interest – that’s for sure – it’s too early to say how many of these projects are actually going to proceed,” he says. “The economics around carbon capture are still challenging.”

一位能源部发言人说，艾伯塔省能源监管机构计划在明年第一季度宣布其计划的“成功支持者”。没有人会获得任何政府资金。
