AI in the renewable energy sector
As fossil fuels continue to be overshadowed by the emergence of renewable energy equivalents, AI has taken on greater precedence.
In fact, it could be argued, the advancement of AI and machine learning software has gone hand-in-hand with the increasing viability and applicability of renewable energy sources like solar and wind power.
In an article by Supply Chain Digital, the advantages of dedicated AI software from C3.ai highlighted the benefits to grid asset management, forecasting ability and increased energy efficiency for the utilities sector generally.
Similarly, Energy Digital explored how utilisation of enterprise AI is gaining momentum at an unprecedented rate across the board:
A survey by Gartner found that the number of enterprises implementing AI had grown by 270% between 2015 and 2019:
“Four years ago, AI implementation was rare, only 10% of survey respondents reported that their enterprises had deployed AI or would do so shortly. For 2019, that number has leapt to 37%,” said Chris Howard, VP, Gartner.
Augmenting renewable energy
Smart grids: The benefits of AI lie in its configuration within ‘smart grids’ - cloud-based, IoT integrated networks which consolidate data into one location and allow analytical software to analyse it for inefficiencies.
Not only this, but forecasting software can be used to more accurately predict weather patterns and environmental conditions, which is essential information for virtually all forms of renewable energy reliant on such factors.
Microgrids: To boost the stability of conventional electricity grids, many energy authorities are choosing to supplement their power during peak periods or for emergencies, such as blackouts - indeed, the international market for microgrids is expected to grow substantially.
AI regulation of energy flow can eliminate the need for wasteful ‘bottlenecks’ of power to prevent overloading grid, but rather enable excess to be stored in battery storage terminals and redistributed as/when it is required.
Safety: With an adequately set up network of IoT sensors, renewable energy companies will be able to monitor the status of their equipment, with AI analysis quickly detecting faults before they have time to develop into costlier problems.
Furthermore, image recognition AI software - such as C3.ai’s geospatial awareness - makes sending engineers into potentially risky situations unnecessary; video footage and photos can be analysed to diagnose faults instead.
Top uses of AI in renewable energy
The company’s vision is to do so “in a cost-effective manner that ensures grid stability as renewable energy sources gradually replace conventional, fossil-fuel generated power plants.”
GE: An innovator in grid analytics for the energy sector, General Electric (GE) released details of its new portfolio designed to optimise grids with AI and ML (machine learning) analytics: Storm Readiness, Network Connectivity and Effective Inertia.
“The energy industry today is leveraging a small fraction of their operational data. Our grid analytics enable utilities to use more of that data and orchestrate their networks and the workers who operate them in ways previously unimagined,” said Steven Martin, CEO.

Carbon dioxide removal revenues worth £2bn a year by 2030
Carbon dioxide removal revenues could reach £2bn a year by 2030 in the UK with costs per megatonne totalling up to £400 million, according to the National Infrastructure Commission.
Engineered greenhouse gas removals will become "a major new infrastructure sector" in the coming decades - although costs are uncertain given removal technologies are in their infancy - and revenues could match that of the UK’s water sector by 2050. The Commission’s analysis suggests engineered removals technologies need to have capacity to remove five to ten megatonnes of carbon dioxide no later than 2030, and between 40 and 100 megatonnes by 2050.
The Commission states technologies fit into two categories: extracting carbon dioxide directly out of the air; and bioenergy with carbon capture technology – processing biomass to recapture carbon dioxide absorbed as the fuel grew. In both cases, the captured CO2 is then stored permanently out of the atmosphere, typically under the seabed.
The report sets out how the engineered removal and storage of carbon dioxide offers the most realistic way to mitigate the final slice of emissions expected to remain by the 2040s from sources that don’t currently have a decarbonisation solution, like aviation and agriculture.
It stresses that the potential of these technologies is “not an excuse to delay necessary action elsewhere” and cannot replace efforts to reduce emissions from sectors like road transport or power, where removals would be a more expensive alternative.
The critical role these technologies will play in meeting climate targets means government must rapidly kick start the sector so that it becomes viable by the 2030s, according to the report, which was commissioned by government in November 2020.
Early movement by the UK to develop the expertise and capacity in greenhouse gas removal technologies could create a comparative advantage, with the prospect of other countries needing to procure the knowledge and skills the UK develops.
The Commission recommends that government should support the development of this new sector in the short term with policies that drive delivery of these technologies and create demand through obligations on polluting industries, which will over time enable a competitive market to develop. Robust independent regulation must also be put in place from the start to help build public and investor confidence.
While the burden of these costs could be shared by different parts of industries required to pay for removals or in part shared with government, the report acknowledges that, over the longer term, the aim should be to have polluting sectors pay for removals they need to reach carbon targets.
Polluting industries are likely to pass a proportion of the costs onto consumers. While those with bigger household expenditures will pay more than those on lower incomes, the report underlines that government will need to identify ways of protecting vulnerable consumers and to decide where in relevant industry supply chains the costs should fall.
Chair of the National Infrastructure Commission, Sir John Armitt, said taking steps to clean our air is something we’re going to have to get used to, just as we already manage our wastewater and household refuse.
"While engineered removals will not be everyone’s favourite device in the toolkit, they are there for the hardest jobs. And in the overall project of mitigating our impact on the planet for the sake of generations to come, we need every tool we can find," he said.
“But to get close to having the sector operating where and when we need it to, the government needs to get ahead of the game now. The adaptive approach to market building we recommend will create the best environment for emerging technologies to develop quickly and show their worth, avoiding the need for government to pick winners. We know from the dramatic fall in the cost of renewables that this approach works and we must apply the lessons learned to this novel, but necessary, technology.”
The Intergovernmental Panel on Climate Change and International Energy Agency estimate a global capacity for engineered removals of 2,000 to 16,000 megatonnes of carbon dioxide each year by 2050 will be needed in order to meet global reduction targets.
Yesterday Summit Carbon Solutions received "a strategic investment" from John Deere to advance a major CCUS project (click here). The project will accelerate decarbonisation efforts across the agriculture industry by enabling the production of low carbon ethanol, resulting in the production of more sustainable food, feed, and fuel. Summit Carbon Solutions has partnered with 31 biorefineries across the Midwest United States to capture and permanently sequester their CO2 emissions.
Cory Reed, President, Agriculture & Turf Division of John Deere, said: "Carbon neutral ethanol would have a positive impact on the environment and bolster the long-term sustainability of the agriculture industry. The work Summit Carbon Solutions is doing will be critical in delivering on these goals."
McKinsey highlights a number of CCUS methods which can drive CO2 to net zero:
- Today’s leader: Enhanced oil recovery Among CO2 uses by industry, enhanced oil recovery leads the field. It accounts for around 90 percent of all CO2 usage today
- Cementing in CO2 for the ages New processes could lock up CO2 permanently in concrete, “storing” CO2 in buildings, sidewalks, or anywhere else concrete is used
- Carbon neutral fuel for jets Technically, CO2 could be used to create virtually any type of fuel. Through a chemical reaction, CO2 captured from industry can be combined with hydrogen to create synthetic gasoline, jet fuel, and diesel
- Capturing CO2 from ambient air - anywhere Direct air capture (DAC) could push CO2 emissions into negative territory in a big way
- The biomass-energy cycle: CO2 neutral or even negative Bioenergy with carbon capture and storage relies on nature to remove CO2 from the atmosphere for use elsewhere
