1/ Here's what the evidence not funded by any industry interests says about hydrogen for heating. I published a meta-review of all independent existing studies I could find in September.
2/ The paper "The viability of implementing hydrogen in the Commonwealth of Massachusetts" would have been excluded in my review because it did receive industry funding. frontiersin.org/articles/10.33…
3/ This is what the paper states where funding came from.
4/ The Boston Globe has found out: hundreds of pages of documents obtained by a public records request reveal that the authors knew that the funds had been solicited directly from some of the foundation’s members in the natural gas and pipeline industry.
5/ The authors state in the paper that there is no conflict of interests.
6/ Emails sent among the study’s principals and their funders reveal that specialists at a gas grid company and a business lobbyist with ties to the industry were allowed to review and suggest changes before the study was released.
7/ And some of the study’s recommendations were substantially written by the lobbyist. This is not just a conflict of interest but misleading as the lobbyist is not listed as an author of the paper.
"My personal take is this should not have been published in a peer reviewed journal as it is, because I think the presentation is biased, slanted, and misleading in a way that’s hard to defend academically."
9/ Frontiers in Energy Research is part of Frontiers Media. In 2015, Frontiers Media was classified as a possible predatory publisher.
10/ "Frontiers has used an in-house journals management software that does not give reviewers the option to recommend the rejection of manuscripts" and the "system is setup to make it almost impossible to reject papers." Source is: "Pseudoscience: The Conspiracy against Science"
11/ In 2017, editors were removed, allegedly for their rejection rate being high. In December 2017, Adam Marcus and Ivan Oransky of Retraction Watch wrote in the magazine Nautilus that the acceptance rate of manuscripts in Frontiers journals was reported to be near 90%.
12/ Why does this matter? It means that the paper has not undergone the usual scrutiny of a peer-review process published in a journal that seems to publish almost anything submitted.
13/ That is the reason that I publish in reputable journals such as Nature Energy, Joule, RSER, Energy Policy etc. - you get 3 or more people to scrutinise your paper and often they will reject it.

1/ Yes COP is a circus and a talking shop. The quality of the conversations differs with some events being poorly attended and the level of discussion low. Navigating the COP venue is challenging and sensory overstimulation in terms of noise and the sheer number of people.
2/ But nowhere else have I met so many leaders from key players in the clean energy space in one place. This includes government officials, international organisations, business associations, think tanks, NGOs and academics.
2/ The EU @Energy4Europe played a key role in socialising the idea of energy labels and standards after introducing the first labels in 1992. This approach was copied all over the world. ec.europa.eu/energy/sites/e…
Solar and wind have seen huge drops in cost over the last decade according to @IPCC_CH.
Solar ⬇️ 85%
Wind ⬇️ 55%
But skeptics often state that using levelised cost of energy (LCOE) as a metric is meaningless because it ignores cost of integrating solar and wind.
A response. 🧵
1/ Commentators in the mainstream and on social media often still contend that the need for a back-up for wind or solar makes them prohibitively expensive.
2/ Luckily the question of integration costs has been studied in great detail. The @IEA started to provide value‐adjusted LCOE (VALCOE) incorporates information on both costs and the value provided to the power system. IEA data for Europe below.
Producing green hydrogen in the UK is expected to cost 3-11x more than fossil gas at pre-pandemic levels.
Analysis of official UK government data below.
🧵
1/ Predicting future costs of green hydrogen is associated with significant uncertainties. There are multiple sources out there ranging from more pessimistic to more optimistic cost pathways. I used UK government data published last year. gov.uk/government/pub…
2/ Pre-pandemic gas prices at wholesale level have been obtained from Ofgem on a monthly basis. I used the average for March 2015-Feb 2020. Not much variation with an average of around 43p/therm equivalent to 1.5p/kWh. ofgem.gov.uk/energy-data-an…
It will be much more expensive to operate gas-fired power plants in the long term than to build new solar PV capacity in Europe says new study by @RystadEnergy.
1/ Gas prices have risen from an average of €46 per megawatt-hour (MWh) in 2021 to €134 per MWh so far this year. Rystad Energy forecasts that TTF prices will stabilize at around €31 per MWh by 2030.
2/ This puts the levelized cost of electricity (LCOE) of existing gas plants closer to €150 per MWh. That’s still three times more than the LCOE of new solar PV facilities.
